Maybe there are no good guys.Abby to Clarke Griffin
Abby was the Chief Medical Officer and a former Council member on the Ark. She was on the Council when they chose to send the 100 to Earth and had been monitoring them throughout the first season. She was the former Chancellor of Arkadia but struggled with leadership due to the rebellious actions of her daughter, Clarke Griffin. She took the City of Light Key to save Raven Reyes from further physical pain. Later, she is unchipped and saved by Clarke. Throughout the fourth season, Abby researches a way to create Nightblood, becomes girlfriend of Marcus Kane. Then Raven reveals to Abby about how to cure her seizures.
In "Adjustment Protocol," Abby becomes a Nightblood to protect Madi. As a result, Russell Lightbourne wipes Abby's mind, effectively killing her and turns Abby into the new host for his wife Simone. Simone is floated by Clarke shortly thereafter, killing Abby's body as well which is left floating away into deep space. In lieu of a body, Abby's wedding ring, returned by Russell to Clarke, is buried on Sanctum next to the dead Flame in "False Gods" as a form of funeral.
Abby's husband discovered an error with oxygen levels on the Ark and, knowing that it meant that life would stop being sustainable, thought the people had a right to know. Abby and the Council disagreed because they feared it would only cause riots and mass panic. Jake was going to go public with this knowledge anyway, but only Abigail, Clarke, and Wells Jaha (Clarke's best friend whom she had told in confidence), knew about it. Abby accidentally condemned Jake before he was able to release the video recording that he made because she told Chancellor Jaha, hoping he would convince Jake not to go through with it. Instead, Jaha arrested Jake and had him floated immediately. After watching her father being sucked into space, Clarke was put in juvenile lock-up, also known as the Sky Box, because of her knowledge of the error. Abby allowed Clarke to think it was Wells who had turned her father in, causing problems in both relationships.
Abby was part of the organization and running of the 100 program that sent 100 prisoners, including Clarke, down to Earth, although it was revealed in the Pilot that Abby did not have the final word about who was sent down to the ground, and it was Marcus Kane who made the final decision to include Clarke in the 100.
In Season Five, after the prisoners arrive back to Earth, a prisoner, Michael Vinson, starts giving her addicting pills. To make sure Abby can't die from not taking pills, Vinson has to kill other prisoners from pills, "knowing what it's like to crave something."
In Pilot, Abby's 17-year-old daughter Clarke tries to escape from the guards that came to collect her from her cell. Abby appears and hugs her daughter close to her. Clarke believes the Council is pushing up her execution date which is still a month away to help reduce the population on the Ark. Abigail reassures her that she's not being executed. Instead, they're being sent to the ground, all 100 of them. A guardsman shoots Clarke with a tranquilizer and she is put on board a dropship headed to Earth.
On the Ark, Marcus Kane informs everyone the 100 have landed but communications are down. It is only thanks to Abby's wristbands that they know what is happening on Earth. Abby informs Kane that so far they have two dead kids; they show as dark tiles. Abby and Eric Jackson theorize the two were killed on impact because they went black at the same time they lost communication. Kane deduces if it was radiation that killed them, there would be more fatalities showing up already. Kane is curious about what Abby thinks all of the red means. Abby explains it is either injuries sustained in the landing or they are excited to be there. Later, Callie Cartwig asks Abby how Clarke is doing. Abby replies Clarke's vital signs are strong but her blood sugar is low. The phone rings and Abby rushes to leave, informing Callie and Kane that the Chancellor has been shot.
Abby and Jackson operate on the Chancellor. During the operation, the Chancellor begins to awaken. Abby orders the nurse to increase the anesthesia. The nurse is hesitant, however, and Jackson notes that they have used too much blood and anesthesia and is worried about breaking the law. Abby tells him the Chancellor is dying and increases the anesthesia, herself.
Abby enters Earth Monitoring Station as Callie approaches and asks how the Chancellor is doing. Abby tells her she hopes he makes it through the night and asks if they have lost any more Delinquents. She is told John Murphy and John Mbege have gone dark and Kane tells her it did not happen during the landing. Abby says it is not radiation because that is not how radiation presents. Kane says it could be if there was enough of it but Abby says if there was that much, all of the Delinquents would be dead. Later, Abby mentions ten more tiles have gone dark. Jackson tells her to look at plasma osmolarity going up across the board and Abby realizes the Delinquents found water. Commander Shumway enters with Kane and publicly arrests Abby for "exceeding the maximum medical supplies allowed per patient." Abby tells Kane that breaking the law to keep him from becoming Chancellor was the easiest decision she has ever made. Kane, as Chancellor Pro Tempore, finds her guilty. Abby brings up the fact that he pressed charges against her husband and daughter and now this and that he is hiding behind the law. Kane sentences her to death and sets the execution for the next morning. He tells her he does it to ensure the human race survives. Abby tells him that is the difference between them, she wants to make sure the human race deserves to survive. Kane has her locked in Clarke's old prison cell where she sees all of the drawings Clarke had made over her year in solitude and cries.
Abby stares out a window into space as a guard opens her door and tells her it is time. She is led to an airlock where Commander Shumway and Kane wait. Callie hugs her goodbye and Abby walks into the airlock with Shumway sealing it behind her. Abby tells Eric Jackson to talk with Jacapo Sinclair in engineering about figuring out how to reverse-engineer the wristbands to communicate with the Delinquents. Kane gives the nod to Shumway to float Abby but is told to stop by Chancellor Jaha who has awoken from his surgery. He pardons Abby and tells Kane he will deal with him later. Shumway opens the door and Abby walks out of the airlock and orders Jaha back to bed before she leaves with Callie.
In Earth Skills, Jackson tells Abby that rumors are going around about the Delinquents' dropship launch. He reports that 23 Delinquents' tiles have gone dark with spiking vitals prior. Abby says there is another explanation. Jaha walks in and sees Wells' dark tile. Marcus Kane tells Jaha that the wristbands are telling them the Earth is not survivable. Abby asks Jaha to trust her because, for all they know, the kids are fine.
Later, Abby is checking Jaha's injuries and asks for his stance on Kane's Population Reduction Plan. If they do not act to reduce the population on the Ark, everyone will be dead within four months from lack of oxygen. Abby tells him they need to give more time to the Delinquents on the ground. Jaha tells her she has no proof and hope isn't enough when the end of the human race is at stake. Abby leaves as Kane enters and Jaha confronts him about almost floating Abby.
On their way into the mess hall, Jackson tells Abby that Kane is lobbying for votes and she should, too. Raven Reyes comes up and asks Abby about the quarantine in lockup and how she saw open ducts. Abby explains the virus isn't airborne and Raven confronts her about the Council hiding something. Later, Jackson and Abby are going over the data from the wristbands when Abby catches Raven eavesdropping from the air ducts. Raven tells them the Delinquents aren't dying; they're taking off their wristbands because they were told not to. Abby goes to speak before the Council and tells them the kids are taking off their wristbands by choice. They ask how that explains Wells' dark tile and Abby tells them the point is the kids need more time. Kane tells her they do not have time because engineering needs six months to fix the oxygen problem when they will be out of oxygen in four months. Every day they delay the culling, 10 more people will need to be sacrificed. Today, it is 209 and they need to vote now. The vote is split 3-to-3 with the Chancellor to break the tie. Jaha talks about how they were supposed to be a transitional generation but now they will be the generation who either returns to Earth or dies out. He still has hope so he will abstain from voting, ending the vote in a tie to be taken up in ten days. He tells Abby she has ten days to get proof.
Raven is called into a level of the Ark that is considered off-limits. Abby tells Raven that the Ark is dying and Abby has ten days to prove the Earth is survivable before they reduce the population by 320 people. Abby reveals a 130-year-old escape pod and tells Raven to get it ready in nine days. Raven tells her she can do it but she is going Earth with her.
In Earth Kills, in a flashback to a year ago on the Ark, Clarke and her father, Jake Griffin, are watching a soccer match from 2001 on a projection along with and his father, Chancellor Jaha. They joke with each other about the predictable outcome of a game that happened 147 years prior as Abby returns home. She tells Jake that the Systems Analysis he asked for is ready. Jake checks his watch and excuses himself.
Later, Abby asks Jake how his discussion with Jaha went. Jake tells her it is definitive that the Ark only has a year or two of oxygen left. He can't fix it because it is a system failure and the people have a right to know. Abby tells him he can't let people know because they will panic and asks him to promise her that he will obey the Council's orders and keep it quiet, at the very least for Clarke. Abby warns Jake that if he doesn't, he'll get floated while Clarke eavesdrops on the conversation.
Jake is saying goodbye to Abby prior to being floated for trying to tell the people the truth about the oxygen shortage. Abby tells him that Earth is their only chance. He hands her his wedding ring and is about to give her his watch for Clarke when Clarke runs in and they hug. He hands Clarke his watch and tells her to keep it for him. Jaha tells him it is time and Jake tells Clarke he loves her as he walks through the airlock. Clarke says, "I love you," back as they close the airlock and Jake is floated. Clarke collapses into her mother's arms crying inconsolably.
In Murphy's Law, at the Camp, Clarke tells Finn Collins how Wells Jaha let her hate him so she would not hate her own mother for killing her father and decides to make Abby feel what she is feeling. Up in the Ark, an alarm sounds in Earth Monitoring Station and Abby sees that Clarke's tile has gone dark. Jackson tries calming Abby as she tries to rationalize why Clarke's wristband would be terminated and asks Jackson for a record of Clarke's vital signs.
Later, Kane stops Abby and asks her if she is heading to Mecha station and asks why she has been down there nine times in the past week. He invites himself along but Abby tells him he will have to be inoculated because a mechanic came down with strep and she doesn't want another outbreak. Kane declines and asks her to keep him informed. Abby leaves to meet with Raven at the drop ship she is refurbishing. Raven tells Abby there's a delay with the ship because she needs a pressure regulator before they can launch. Abby tells Raven that Clarke's wristband went out and Raven tells her she will get a pressure regulator that day. Raven leaves for the mess hall to speak with Nygel, the woman in charge of black market operations on board the Ark. Raven asks for a pressure regulator and Nygel tells Raven that she will need to sleep with the Chief of Electrical in order to get the part. Raven tells Nygel to float herself and Nygel tells Raven that her mother took that deal...many times, causing Raven to get irate and be carried out by Nygel's workers.
Raven is waiting in a long line for Medical. She approaches Abby and coughs discreetly and Abby does a cursory medical check on her before pulling her away into private consult, explaining the long line is due to oxygen deprivation. Raven tells Abby that Nygel would not give her the pressure regulator and Abby tells Raven she can get the part from Nygel. Later, Abby approaches Nygel in the mess hall and slips Nygel some morphine for the pressure regulator. Back at the refurbished drop ship, Abby hands Raven a pressure regulator and Raven tells her it might take a few hours to install it. A few hours later, Abby is pacing around while Raven works on the drop ship. Jackson comes in on Abby's telecommunication device and asks if she stole morphine. He tells her that Kane is on his way to arrest both her and Raven. Abby can't believe that Nygel turned her in and asks Raven how much longer. Raven tells her twenty minutes and Abby says that Kane will be there in five. She tells Raven that no matter what, she needs to launch the pod, with or without her, and radio back if she makes it or 300 people will die. Abby asks Raven to tell Clarke she loves her.
Raven gets the pressure regulator hooked up as Kane heads toward Mecha Station to arrest Abby. Raven realizes the pressure regulator is broken just as Kane approaches Abby who was waiting for him in the hallway. Abby tells him she did it for her daughter and she still believes the Delinquents are alive. Kane asks Abby what the pressure regulator is for and if there was even a staph infection. Raven dresses in a spacesuit since the pressure in the drop ship won't be regulated and begins the launch sequence for the pod. As Kane is having Abby arrested, Raven launches the drop ship and begins her descent to Earth. Abby tells Kane they have to know the truth.
In Twilight's Last Gleaming, Abby is still in Lockup when Jaha comes to visit her to tell her that they're reaching critical oxygen shortage levels within the Ark. The Council has granted Abby temporary work-release because so many of the Sky People are suffering from pulmonary toxicity. Jaha tells Abby that the Council approved Kane's population reduction plan and they start the Culling of 320 people in twelve hours. Abby asks about Raven Reyes and Jaha tells her that she will probably die like all of the others. Abby goes to work in medical, doing a vision check on nine-year-old Reese Lemkin. She has lost all vision in her left eye due to chronic oxygen deprivation. Reese's father, Tor Lemkin tries to put her hair back from her face with a barrette but she jokingly brushes him off before going outside to wait. Abby explains to Tor that the decline in her vision has been accelerating the last few days and Tor wants to know if they'll fix the air problem soon because his daughter should not have to deal with going blind and he leaves. Jackson comes up and asks Abby if she is all right. She tells him to listen to the radio because that is the only way they will be able to help everyone on the Ark.
Later, Abby confronts Jaha and asks him if it is true that he is going to die in Section 17 and leave the Chancellorship in the hands of Kane. Abby tells him that it is happening too fast and they have other options and possibilities left to try first. She tells Jaha he is a coward and he is running away before she leaves him. She goes to her quarters and removes a memory stick with Jake Griffin's message to the people of the Ark about the oxygen shortage that he was floated the year before for trying to broadcast. She broadcasts an Ark-wide message of Jake's video telling the people about the oxygen shortage. Commander Shumway alerts Kane and he goes after Abby. Jaha watches the message as Jake tells the people that they need to come together and face the crisis. After his message, Abby comes on and tells the Ark that her husband was killed trying to deliver that message and now, in twelve hours, 320 people will be sacrificed. Kane arrives where Abby is and the guards pry the door open. Jaha yells at Abby that she has made an impossible situation worse. Kane warns them there are 400 people gathered outside. A man tells Jaha that the crowd outside has sent an emissary to speak with Abby. Tor Lemkin enters and tells Abby he saw the video and he wants to "volunteer" for Section 17 because his daughter is going blind and he can help prevent that from happening. More Sky People follow each one volunteering for a spot in Section 17 to give their loved ones extra air. Jaha admits to Abby that Jake was right: it would bring out the best in them.
Tor says goodbye to his daughter, Reese, lying to her about working a double-shift. He tries again to pull her hair out of her face with a barrette and she tells him to stop. They kiss and hug goodbye and he watches her walk away with tears in his eyes. As the volunteers file into Section 17, Kane tells Abby he reminded Jaha that changing to a new Chancellor would be destabilizing. He also tells her he left two men monitoring the radio in case Raven calls in. Abby thanks him as they watch Tor enter Section 17. Jaha thanks Tor for his sacrifice and Tor tells him do not thank him because he's doing it for his daughter. Tor and 319 other Sky People all enter Section 17. Tor holds onto his daughter's barrette as Jacapo Sinclair reports to Jaha that all hatches and vents have been sealed in Section 17 and asks for the order. Jaha instead walks over to Sinclair's station and presses the button himself, terminating the airflow into Section 17. The people in Section 17 begin to fall asleep as the air supply is cut off. Tor plays with Reese's barrette as Jaha gives a eulogy for them. Tor eventually falls asleep, dropping the barrette. Later, Abby and Jackson enter Section 17 where the 320 bodies are piled where they fell asleep. They start to remove the corpses and Abby picks up Reese's barrette from where Tor had dropped it.
Later that night, Jaha visits Abby in lockup and passes her a flask as he tells her they make the best choices that they can and hope for forgiveness. She asks if they even deserve to be forgiven. Suddenly, Abby and Jaha see the rocket flares from the Delinquents through the window.
In Contents Under Pressure, Abby stands before the Council and is told that even though she broke laws and should be floated, they need her medical expertise too badly so she has received a stay of execution. Then suddenly they hear Raven calling over the Ark-wide channel, asking for help from the ground. Sinclair boosts the signal and Abby is able to talk to Clarke for the first time. Clarke asks for help with Finn and tells Jaha that Wells did not make it. Sinclair patches Clarke through to medical so Abby and Jackson can help Clarke with Finn's stab wound. The storm, however, temporarily disrupts communications. Abby is able to get back on the radio and Clarke describes Finn's injury to her. Abby guides Clarke through removing the blade from Finn's side. As Clarke is doing so, the storm gets worse and debris hits the drop ship, knocking everyone down, including Clarke and Finn. Luckily, the blade was removed without doing further damage. Clarke finishes stitching up Finn's wound and realizes he is feverish. Abby wants to talk with Clarke but she leaves for the third level. Later, Abby comes back on the radio and Clarke tells her she knows about her mother's involvement with her father's death.
In Day Trip, Jaha tries to get Clarke to forgive her mother for getting her father killed, however, Clarke refuses to speak with her mother.
In Unity Day, Chancellor Jaha gives a Unity Day Celebration speech on the Ark about how everyone will be on the ground next year. He tells that the first Exodus ship will be sent down to Earth in 60 hours with reinforcements. Everyone claps and Diana Sydney approaches Abby to ask if there are any hard feelings about her taking Abby's Council seat. Jaha cuts his speech short to begin the Unity Day pageant and Diana remarks on it to Abby before leaving. Jaha introduces the children who will be performing "The Story of Us." A girl in the pageant begins reciting how long ago, 12 Stations were floating alone when they decided to join together. Suddenly, an explosion blasts through the room. Arkers are lying unconscious and dead and people are scrambling to help. Abby asks if Jaha is okay and Jaha tells Kane to find out who did this. Kane finds his mother dying, impaled with a shard of metal. Abby comes over to help, but there isn't anything she can do. Kane realizes that four members of the Council are dead, telling Jaha that it was a coup and they need to get him out of there. They realize that Diana is missing and Jaha orders a lock-down while Kane goes looking for Diana.
Abby goes to the Exodus ship and begins packing first-aid supplies. She tells Kane that she is sorry about his mother. Diana comes running up and tells them they need to delay the launch because a mechanic, Cuyler Ridley, is the terrorist who planted the bomb because his wife died in the Culling and he has turned himself in. Kane questions Diana on why she left the pageant early and she tells him she was lucky. Kane leaves to question Ridley. Later, Abby is still packing the medical supplies while talking to Red, a mechanic, when Diana and her people take over the drop ship. Red makes a run for it back to the Ark and Diana tells them to let him go because she is going to lead everyone else home. Jaha and Sinclair arrive and help Red try to get the door open to the Service bay to prevent them from launching the drop ship. Ridley finds Abby hiding in the bay and brings her to Diana. Diana asks Abby to come with them because they need a doctor and Abby owes no loyalty to Jaha, the man who floated her husband and she'd be able to see Clarke again. Instead, Abby runs and tries to open the door for Jaha and is baton-shocked by one of Diana's guards but the door opens wide enough for Red to get a pry-bar in. They start trying to jack the door open when Sinclair realizes they haven't decoupled the drop ship from the Ark, meaning that all of the systems on the Ark will be crippled and everyone will die if the dropship launches. Jaha begs Diana not to do this and Diana tells everyone the truth: there aren't enough drop ships to get everyone to the ground. Red tells Jaha he doesn't trust either of them but he's going to the ground. He climbs through the door to the drop ship and knocks the jack loose, sealing the door so the drop ship can launch. The drop ship yanks away from the Ark, causing the power to go out and catastrophic damage across the Ark. At the Camp on Earth, there is a sonic boom and Clarke and Bellamy look up to see the Exodus ship coming down a day early, much too fast, and without a parachute. An explosion is seen in the distance and Clarke crumples to the ground in grief when she realizes her mom is dead.
In I Am Become Death, Clarke, Raven, and several other Delinquents investigate the Exodus drop ship crash but there are no survivors. Later, Raven tells Clarke she still hasn't been able to get back in contact with the Ark since the Unity Day Celebration and she has a bad feeling. She also tells Clarke she's sorry about her mom dying.
In The Calm, after the Exodus ship caused system-wide failure on the Ark, Sinclair discovers the service hatch was manually sealed before the launch of the Exodus ship, meaning there are survivors still in the service bay. Kane decides to go after them by going through an overheated maintenance shaft. He climbs through and sees people lying on the other side of the door in the service bay. He uses a battery Kyle Wick gave him to open the door and rushes inside, waking everyone up. He finds Abby curled in a corner and tells her to wake up as she opens her eyes.
In We Are Grounders (Part 1), Jaha is speaking with the Council and the Station Representatives, telling them that there is no way for anyone to get to the Earth. He says the Delinquents are their final hope and everyone should find peace within themselves in their final hours. He releases all resources to the people and told them that there would be no more rationing. Abby tells Jaha she needs to help a patient injured in the Exodus ship disaster and leaves. Abby and Jackson start working on an injured girl who looks a lot like Clarke. Jackson tells her they should have left her alone because they'll all be dead in two days anyway. The girl begins to convulse and Abby gives her a shot of epinephrine. When she asks Jackson for more epinephrine, he tells her they are all out and Abby has to let her patient go. Abby tells Jackson that Clarke blames her for her father's death and she'll never get to hug her again or protect her anymore. Jackson tells her that Clarke is strong-willed like her mother and that is what will keep her alive on the ground. They hug and she tells him to leave before she starts crying over the dead patient.
Later, Kane is running through simulations with Sinclair as he tries to find a way to save some of their people. Jaha enters and asks if they've tried not saving the Ark yet. He suggests they use the thrusters to propel the Ark into the atmosphere and tells Sinclair to find the 5% of the Ark that would survive. He asks Abby if she is ready to see her daughter again.
In We Are Grounders (Part 2), on the Ark, Sinclair informs Jaha, Kane, Abby and the other inhabitants of the Ark about the workings and possible consequences of bringing the Ark to Earth, explaining that some parts of the Ark will be destroyed when entering the atmosphere along with the people inside. Jaha tells the Station Representatives that they have no other choice if they do not want them all to die. Once everyone is strapped into different Stations on the Ark, Jaha gives the Traveler's Blessing across the PA system and tells Sinclair to begin their journey back to Earth. Sinclair tries to remotely separate the Ark's stations from GoSci and the Earth Monitoring Station with explosives so they can use the Ark's thrusters to blast them towards Earth, but the remote detonation fails. Sinclair informs Jaha that someone will have to manually detonate the bombs thus, someone must stay behind. Kane volunteers and is ready to leave. Abby asks how much air Kane will have and Sinclair tells her that Kane will have one week, two weeks at most. Suddenly, the bombs explode, shaking the Ark. Jaha tells Abby from Earth Monitoring Station that she will see her daughter soon. The Ark's stations separate from GoSci and head for Earth as the thrusters activate.Up in space in the remnants of the Ark, Jaha attempts to contact any surviving stations and is able to reach Abby on Mecha Station who was with Kane and Sinclair. She tells him they landed successfully and goes outside and describes what she sees to an emotional Jaha. Kane joins her outside and they see smoke in the distance in the mountains. Abby thinks it may be one of the other stations and Jaha advises that they check it out.
In The 48, Abby is reunited with the other Ark citizens on the ground. She finds Raven in the dropship and asks her how she got hurt, and Raven tells Abby that she was shot. Abby proceeds to ask where Clarke is, but Raven says that Clarke wasn't with her and that she is gone. Abby, along with the others, go to Camp Jaha.
In Inclement Weather, Abby orders a search team to go out and look for survivors. Abby performs Raven's surgery but tells her risk involved before she begins. Later, Kane and Abby talk about Raven and Bellamy, and Abby realizes that Kane never sent out the search team she asked him to send out, and is angered by that. Later, Abby breaks the news to Raven that she has nerve damage to her leg due to the damage from the bullet and because of that, she won't be able to use one of her legs. At night, Abby, along with Miller's dad, give guns to a group of Delinquents and allow them to go search for their friends.
In Reapercussions, Abby admits to Kane that she has committed a crime by sending armed Delinquents to search for their friends. At first, Kane doesn't want Abby punished, but Major Byrne successfully convinces him that it must be done to maintain order amongst the people. So, Kane orders Abby to be shock lashed ten times. After that, he comes to see Abby and she admits that he can shock lash her a hundred times, but she still doesn't regret what she did. Kane proceeds to ask her to be the Chancellor, to which she accepts.
In Human Trials, Abby is reunited with Clarke. Clarke is surprised and happy to see that Abby became the Chancellor, and she tells her mother about Mount Weather. Abby doesn't allow her or any other of the Delinquents to leave Camp Jaha to go find Finn and Murphy. However, Clarke goes against her mother's wishes and leaves with Octavia and Bellamy. Abigail suspects Raven had something to do with their escape plan, which she did, and interrogates her. Abigail becomes frustrated with Raven and slaps her across the face, which she immediately regrets. She explains that Clarke is still just a kid, but Raven argues that Clarke stopped being a kid the day Abby sent her down to Earth to die.
In Fog of War, two days after Finn's massacre at Lincoln's village, Raven Reyes reveals to Clarke she figured out why they had not heard from any of the other Stations: Mount Weather has been jamming their signals. Major Byrne overhears the conversation and tells Abby about it. Later, while Raven is explaining to Clarke how Mount Weather has been jamming their signals and even crashed the Exodus dropship that came down on Unity Day, Abby interrupts them and tries to stop them. Clarke and Raven convince Abby that they need to take down the radio tower on Mount Weather so they can find any other Ark survivors to help build their army. Abby tells Byrne to stay behind and guard the camp because Abby will be going with them to Mount Weather.
Clarke, Abby, Raven, and several other Sky People hike to Mount Weather to take out the radio tower. They stop and survey Mount Weather and Raven spots the radio tower. Finn gets upset because of the way everyone is acting towards him since the massacre and storms off with Clarke following after. Suddenly, Acid Fog starts rolling towards them and Clarke and Finn hid in the bunker. Meanwhile, Abby and Raven take cover in a tent from the Acid Fog as Raven attempts to get a radio signal. She picks up an encrypted channel and realizes they will be able to listen in on Mount Weather. Eventually, while they're still trapped by the Acid Fog, Raven breaks the encryption on the radio channel and they overhear the Mountain Men discussing "the veil." Abby wants to blow the radio tower to find out if there are any other Ark survivors but Raven tells her if she does blow the tower they won't be able to listen to the enemy anymore and that she knows what Clarke would do. Once Clarke and Abby meet back up at Camp Jaha, Abby tells Clarke that they decided against blowing the radio tower because they're not sure if there are any Ark survivors but they are sure that there are 47 Sky People trapped in Mount Weather. From the forest, a bloody Jaha approaches and tells them he has a message from the Commander: "leave or die, we have two days."
In Long Into an Abyss, Abby and Jaha discuss their options of what to do about the Commander's order they leave or be killed. Abby wants to rescue the kids in Mount Weather but Jaha wants to flee. Major Byrne interrupts and tells Abby the rest of the Sky People are getting restless and need to hear a word from their Chancellor. Abby goes outside and tells everyone at Camp Jaha that yes, the Grounders have threatened them but they haven't made any decisions yet. Jaha tells everyone to pack and be ready to leave if they need to. He will lead them across the Dead Zone and to the City of Light. Clarke interrupts and asks about the Delinquents still trapped in Mount Weather. Abby tells everyone that no decision has been made yet, and they should all report to their station supervisors. Later, Sgt. Miller tells Abby that he's not leaving Camp Jaha without his son. Abby tells him to pack his things and report to Major Byrne because she wants everyone out of camp by dawn.
As everyone is preparing to evacuate from Camp Jaha, Clarke arrives from the dropship and tells Abby that she knows how to stop the Grounder threat by showing them the Sky People can save the Reapers. Suddenly, fire start to appear in the darkness of the night and everyone realizes the Grounder army has arrived. Jaha tries to take control of the situation and force everyone to evacuate but Abby stands her ground. Jaha tells Sgt. Miller and Major Byrne to arrest Abby but they only listen when Abby tells them to put Jaha in the stockade. Abby decides to head back to the drop ship to try and save Lincoln, while Clarke goes to talk to the Commander.
Abby arrives at the drop ship and gives Lincoln a shot to bring down his fever when he starts convulsing. He stops breathing and Abby begins chest compressions. Clarke is leading Lexa and her guards through the carnage outside the drop ship while Abby is trying to get Lincoln breathing again. Abby finally gives up and says that Lincoln is gone. Octavia refuses to believe her and continues chest compressions. Clarke and everyone else enters at that moment and they are at a standstill with everyone going for their weapons. Abby picks up the shock baton and holds it in front of her before using it as a defibrillator on Lincoln, shocking him twice before he starts breathing again, much to the Grounders' surprise and the Sky Peoples' relief.
In Spacewalker, Abby and Clarke visit with Octavia and Lincoln who is still recovering from being a Reaper. Abby asks Lincoln how to negotiate with Lexa in order to save Finn but, he says there is no way out of it and Finn must die. Octavia asks what would happen to him and Lincoln tells them that because Finn killed 18, he will suffer 18 deaths as a result. Clarke asks how he can say that about his friend and Lincoln tells Clarke that some of the people Finn massacred were also his friends too. Abby visits Raven where she is locked up in the stockade with Jaha after striking Major Byrne and allows her to go free. Jaha tells Abby she should give Finn up to keep them safe.
Later, as the Grounders start chanting loudly, Jus drein jus daun! ("Blood must have blood!"), Abby walks up to the gate to talk to the two riders Lexa left behind and tells them the Sky People are ready to fight if that is what it comes to. The riders take off back to Lexa's camp and they see someone else approaching: Marcus Kane. Kane, Abby, and a handcuffed Jaha meet to discuss the situation. Kane tells them he has gotten to know the Commander and she might be willing to allow the Sky People to put Finn on trial. Kane tells Abby it is the most merciful outcome for the boy. When Abby leaves the room, Raven and Bellamy confront her, asking her what they're planning to do with Finn and she tells them they are all trying to find a way out of the situation. Bellamy realizes that they are going to give Finn up. Kane and Abby go talk with Lincoln again and ask if Lexa would be willing to accept a deal where the Sky People put Finn on trial instead. Lincoln tells them it is not possible because Finn killed innocent people and they're already lucky because if it were up to Indra, all of the Sky People would be dead. Abby decides she needs to speak with Indra. Abby meets with Indra outside Camp Jaha and tells Indra she doesn't want to see any more people die. Indra tells Abby that she lies because they saw Finn in the forest. Indra says that Finn must die for what he has done.
Once Finn surrenders himself to the Grounders, Abby, Clarke, Raven, Bellamy, and the rest of the Sky People watch as the Grounders start setting up for Finn's execution. Abby says there is nothing to be done. Clarke decides to speak to Lexa one more time about sparing Finn's life, and Raven gives her a knife before she leaves. Abby watches as Clarke asks if she can say goodbye to Finn and Lexa allows her to. Clarke walks over to Finn and hugs him. When she steps away from him, she reveals that she has killed him with the knife Raven gave her. Lexa tells her warriors that it is done and keeps them from attacking Clarke.
In Remember Me, Clarke is alone in Lexa's tent as she tries to scrub Finn's blood off her hands after having mercy-killed him. Abby enters and hugs Clarke as she cries. Marcus Kane enters with Gustus behind him. Gustus tells Clarke the Commander is ready to talk. Lexa tells Clarke that Finn's body will be given to the people of Tondc since Clarke denied them their justice. Kane and Abby get into a disagreement with Indra over this but Clarke agrees to it. She says once it is done, they will talk about getting all of their people, both Sky People and Grounders, out of Mount Weather. Clarke tells Abby that if the truce doesn't hold, she killed Finn for nothing and walks away. Abby tells Kane that the Grounders are being led by a child and he responds, "so are we."
While camping for the night, Clarke places her mat on the side of the Grounders. Bellamy tells her it is safer on their side but Clarke says they need to trust the Grounders. Bellamy places his stuff down on the Grounder side as well. Behind them, Kane and Abby discuss Jaha and what they should do with him. When they arrive at Tondc all the Sky People have to disarm before entering. Raven stubbornly forces Gustus to search her and disarm her. As they enter the village, Grounders shout at the Sky People, calling them murderers. One man stands in their way because he lost both his wife and child. Gustus fights the man and is about to kill him when Clarke begs Lexa to stop him so the Sky People won't get blamed. Lexa calls it off and announces to everyone that if anyone tries to stop the alliance, they will pay with their life. Later, Lexa gives a eulogy for the dead in front of a funeral pyre. She passes the torch to Clarke who steps up and as she lights the pyre, she says, Yu gonplei ste odon ("Your fight is over").
Later, at the alliance banquet, Kane presents Lexa with a bottle of homemade alcohol as a gift. Clarke and Lexa both take a goblet but Gustus stops Lexa and takes a sip first before giving it back to her. As they toast and are about to take a sip, Gustus falls over having been poisoned. The Sky People are searched and they find the poison on Raven. She claims it is not hers and that Gustus put it there when he searched her. Lexa commands for all of the Sky People to be locked up. Clarke asks Raven if she tried to poison Lexa and Raven punches Clarke in the face, and tells her that "She's the only murderer here". Clarke sees Finn standing behind Raven and begins talking to him. Abby tells Clarke she knows how she feels and Clarke doesn't like the comparison between Finn's death and her dad's death but she realizes they are the same. Kane goes over to talk to Clarke and tells her that they need to figure out who would want Lexa dead. They come to the conclusion that the poisoner had to be someone who was trying to break the alliance. Nyko and Indra return and take Raven away. Indra tells them that Lexa is merciful and only wants Raven to die. The rest of them are free and they should run. Raven is tied up outside to a pole where Lexa and Indra begin the "Death by a 1000 Cuts." Clarke soon runs outside and asks Nyko for the bottle and drinks from it, showing it wasn't poisoned. Bellamy realizes that it was Gustus who poisoned the cup because he was trying to protect Lexa from the alliance. Lexa commands him to be tied up in Raven's place. As they're leaving Tondc, Abby approaches Clarke to give her some ashes from the fire to say goodbye to Finn but, Clarke tells Abby that she already said goodbye.
In Coup de Grâce, in the woods, two Mountain Men are hidden from sight as they watch Clarke riding with Abby and several Grounders on their way from Tondc back to Camp Jaha. One of them has his sniper rifle trained on Clarke just as the group stops. Abby tries to get Clarke to drink some puddle water but Clarke refuses, telling her she needs to get back to the radio to see if Bellamy has contacted them yet. As they're mounting up, Carl Emerson, one of the Mountain Men, tells the other one he has a shot. Suddenly, the sniper is hit by an arrow and the bullet misses Clarke, hitting a Grounder behind her. Octavia and Indra have found the Mountain Men and Octavia fights Emerson, tearing his radiation suit. Indra tells her to "finish it" just as Clarke rides up and stops her, telling Octavia they want to keep him alive and to check for a patch kit for his suit. Octavia digs through Emerson's bags and finds a picture of Clarke and Lexa on horseback, the intended targets. Indra sends a rider to go warn Lexa of the attempted assassination.
Back at Camp Jaha, Abby is trying to save the Grounder who was shot instead of Clarke. Jackson is helping Clarke with Emerson when Raven says she can hook up scrubbers to the airlock to make it safe to take off Emerson's protective outerwear. The Grounder ends up dying and Indra tells him, Yu gonplei ste odon ("Your fight is over") as she cuts a braid out of his hair. Clarke tells Abby to let her know when Emerson wakes up. Later, Marcus Kane and Abby are standing watch over an unconscious Emerson. They discuss how the Sky People blood heals the Mountain Men. Abby tells him she's worried about Clarke. Once Emerson wakes up, Kane begins to interrogate him but Emerson just repeats his name and rank. Kane threatens to open the door to get Emerson to talk. Clarke tells Kane that torture doesn't work. Kane storms off and Abby puts Emerson under 24-hour guard. Later, A PA announcement requests Clarke's presence at the airlock where Abby is waiting for Clarke and Kane. She tells them that Jackson found genetic anomalies in Emerson's blood that could have only come from a Sky Person. Clarke wants to kill him but Abby tells Clarke she's not in charge.
After Clarke hears from Bellamy in Mount Weather, she brings Octavia, Indra, and several other Grounders with her to Emerson's airlock where Clarke makes the guard stand down and tells Emerson to get dressed. They take him outside and bring him to the gates where Kane and Abby try to stop her. Abby tells the Ark Guards to get the prisoner back inside but the Grounders behind Clarke step up threateningly. Clarke tells Abby, "you may be the Chancellor, but I'm in charge," and refuses to back down. Kane tells Abby that it is time they started trusting Clarke. Abby tells the Ark guards to stand down and Clarke makes her way through with Emerson. She tells Emerson to deliver a message to Mount Weather and that they have a secret Grounder army that the Acid Fog can't hurt. With the tone generator they got off of Emerson, the Reapers can't hurt them either. Mount Weather has one last chance to let the Delinquents go and the Sky People will let them live. Clarke releases air from Emerson's oxygen tank and tells him he has to make the eight-hour walk back to Mount Weather in six hours. Octavia asks how this will help Clarke and Bellamy tells her that it will make them look outside for this secret army instead of inside where they might find Bellamy and that Bellamy is the key to everything.
In Rubicon, at Camp Jaha, Bellamy comes in over the radio and tells Clarke about how the Delinquents are being taken away one by one. Clarke tells Bellamy to find the missing Delinquents and leaves to tell Kane that she is no longer going to Tondc so he needs to go instead. Abby enters and Kane says that maybe the Chancellor should go to Tondc instead but Clarke says Abby is needed at Camp Jaha. Abby shows Kane the note that Jaha left for them saying he is on his way to the City of Light.
Later, after Clarke finds out about Mount Weather's plan to bomb Tondc, Clarke goes there to warn Lexa. Clarke wants to evacuate everyone but Lexa tells her they can't since Mount Weather will know that they have someone on the inside. While they are sneaking out of Tondc Clarke hesitates and tells Lexa if they can find the spotter that will stop the attack. She suddenly sees Abby arrive in Tondc and goes back for her. Clarke gets Abby to leave with her while Kane and Indra realize Clarke and Lexa have gone missing. The missile hits Tondc causing a massive explosion that knocks Clarke and Abby off their feet. Clarke's ears are ringing as she checks on her mom, telling her they have to go. Abby realizes that Clarke knew about the missile ahead of time and can't believe that Clarke would let it happen. She begs Clarke to tell her it was Lexa's decision and not Clarke who did it, telling her she crossed a line but her secret is safe. Abby leaves in disgust and sadness and heads back into Tondc to help the injured.
In Resurrection, Abby and Nyko are racing around to the injured survivors in Tondc. Nyko tells her they can only save those who can be saved. Octavia and Lincoln are also trying to help dig people out of the rubble. Octavia tells Abby that she is sure Clarke is okay. Lincoln finds Indra alive under the rubble and pulls her out. Indra calls him a Reaper and tells him to put her down. There is a loud crack and suddenly, Indra is thrown down by a bullet in her shoulder. Everyone runs from the sniper (Whitman) with Lincoln dragging Indra to some coverage. As people try to move, the sniper shoots at them. Abby hears a noise in the rubble and tells everyone there are people still alive. The noise is being made by a half-conscious and pinned-down Marcus Kane. Abby begins crawling through the rubble and finds Kane trapped underneath debris. His leg is badly injured and when Abby tries to free it, they hear a girl calling out. Kane tells Abby that it might be Clarke. Abby is finally able to pry up the beam that has Kane's leg trapped but she quickly realizes the beam on top of him is keeping him from bleeding out and puts it back in place. Kane tells Abby to go find Clarke and Abby finally admits that Clarke and Lexa knew ahead of time and are safe. Just, the rubble shifts and debris comes crashing down around them.
Abby awakens beneath the rubble and is having a hard time getting herself free. She calls out for Kane and shines her light toward him, telling him to wake up. Kane tells her that he's okay and Abby apologizes to him because Clarke is her daughter and knew about the bombing ahead of time. Kane tells her Clarke did it because she grew up on The Ark and it is just like their flotations and cullings. He tells her they have to answer for their sins which makes Abby question if they even deserve to survive. Abby calls out to Kane but he doesn't respond. She finally manages to push the concrete slab off herself and crawls over to his side, telling him to hold on. Meanwhile, from above them, Octavia is able to break through to where Kane and Abby are trapped. She tells them she'll get them out.
Later, as they're carrying Kane out, Lincoln returns with Clarke and Lexa and reunites with Octavia. Lexa starts to give a speech about making the Mountain fall and avenging the dead when Abby interrupts and tells them there are still others who need saving and to get back to work. Clarke tells Abby she needs to go back to Camp Jaha with the wounded but Clarke will be marching on Mount Weather because the sniper wasn't wearing a hazmat suit which means they are killing the Delinquents. Abby asks her to not forget that they're the good guys.
In Blood Must Have Blood (Part 2), in Mount Weather, the residents have gathered on Level 5. Cage Wallace is told he is needed in the dorm where all of the Sky People are tied up as they extract bone marrow from a Delinquent. Emerson tells Cage that they suffered losses and he is the only one left who has received the bone marrow treatment. Emerson reveals the four additional Sky People they captured outside the Mountain: Zoe Monroe, Sgt. Miller, Abby, and Marcus Kane. The Delinquent on the table dies and they pick Raven to be used next.
Later, in the Command Center, Clarke tells Cage she has his father and will kill Dante if he doesn't let her people go. Dante tells Cage to "stay the course" and Clarke raises up her gun and aims it at Dante. Cage tells his dad he'll take care of their people and Clarke shoots Dante dead. Clarke tells Cage she will not stop until her people are free and will irradiate Level 5 if he doesn't let them go. Clarke tells Monty to get it set up so they can irradiate Level 5 if they have to. In the dorm, Cage orders Raven to be removed from the table and has Abby put on instead. Kane tells them no one has to die because the Sky People can donate it to the Mountain Men. Cage tells him that it will never happen and they can't all survive as they begin drilling into Abby. Bellamy warns Clarke there is no going back if they do this. Monty finishes the settings to irradiate Level 5 as Abby is unconscious on the table, being drilled for bone marrow. Clarke reaches for the lever and Bellamy places his hand on top of hers, saying, "together," and they pull the lever. The Mount Weather residents begin to succumb to the radiation. Octavia runs into the dorm and begins freeing the Sky People as Kane runs over to Abby to help her. Clarke is reunited with her mother in the dorm and tells her she tried to be the good guy. Abby tells her that "maybe there are no good guys." The next day, the Sky People return to Camp Jaha. Kane and Abby enter first with Abby on a stretcher while Kane holds her hand.
In Wanheda (Part 1), at Arkadia, Bellamy goes to see Kane about going into Sector 7. Abby is asleep on a couch. Kane grants permission to go into Sector 7 with weapons but re-enforces the "non-lethal response" rule since there hasn't been a Grounder attack since Mount Weather. Bellamy leaves and Abby wakes up and looks at the Sector map, wondering if Clarke is in Sector 7. Kane offers to send out another search party but Abby declines and tells him that they won't find her until Clarke is ready to be found. Sgt. Miller interrupts them and tells Kane that they got a signal of three clicks on the secure channel, meaning "she" wants to meet.
Later, Abby, Jackson, and Lincoln come running to the gates of Arkadia as Octavia, Miller, and Raven bring back the injured Jasper. Jackson takes Jasper to Medical as Abby asks Raven about Clarke. Octavia comments negatively on Lincoln wearing the Guard jacket and walks away from him to take care of her horse. Abby helps Raven off her horse because she can't get down on her own. Raven limps off to take care of her horse on her own.
Abby has called Lincoln to see her in Medical and tells him about her plans to make another trip to Mount Weather for medical supplies. Lincoln warns her that it might start to look like the Skaikru are colonizing the Mountain, which would break the truce. Jasper comes stumbling out of Medical with Jackson chasing after. Jasper claims he is fine as Raven arrives and says he is not fine. Abby lets Jasper go as long as he promises to come back in the morning. She dismisses Lincoln and tells Jackson she will be back in Medical in a minute. Jackson complains about the backlog of patients, including four contraceptive implant removals but he leaves. Abby corners Raven, asking about her hip and the pain she has had since the explosion at the dam three months ago. Abby tells Raven she is not handling it and that she pushed Kyle Wick away. Raven tells Abby that she should stop hiding her own pain and fix herself because she is failing at being both a chancellor and a doctor.
Back at Arkadia, Raven and Gina are in a common room with numerous other Sky People sorting through supplies from the last Mount Weather supply run. Abby approaches Raven and Raven asks if Abby is there as her chancellor or her doctor. Abby says she is there as a friend. Raven tells her to "shut up and drink" as Gina pours them shots.
In Wanheda (Part 2), Abby tends to Jasper's cut on his face that he got during his fight with Macallan. She sarcastically remarks that follow-up appointments are about checking old injuries and not treating new ones. Jasper smiles and says that he was just trying to make the most of their time together. Abby then changes the bandages on the wound he received from the Ice Nation warrior, and asks him if he wants to talk about it but he refuses. She explains to him that he will never move past Maya's death unless he faces his feelings head on, and reminds him that Finn never faced his feelings and it broke him. Jasper points out that her daughter killed him, too. Octavia, Lincoln, and Jackson interrupt the pair and bring in a dying Nyko. Jackson takes a sample of Nyko's blood for the transfusion he will need and reveals his blood type to be Rh null. Abby states that Rh null can only take Rh null, and nobody has that blood type. Jackson proceeds to offer an alternative but Abby silences him. Lincoln asks what Jackson was going to say, and Jackson offers to take Nyko to Mount Weather. However, Abby scolds him for suggesting that, considering thousands of Grounders were bled to death there. Lincoln says they need to save Nyko, so Abby reluctantly agrees to take him there. She also tells Jasper that she hopes he is ready to face his feelings and brings him along. Abby manages to save Nyko's life, and he thanks her for doing so. Jackson explains the benefits that using Mount Weather can bring to both the Grounders and Arkers. Nyko says that he and Lincoln can change the minds of their people. With that discussion, Abby agrees to use Mount Weather once again, which pleases Jackson.
In Ye Who Enter Here, outside Polis, a truck arrives carrying the Sky People. Kane exits and tells everyone to leave their guns and radios in the truck and Lexa's guards will escort them to the summit. He tells Nelson and Hill to remain behind in the truck and man the radio. He notices one of the Arkadia Guards has a med kit from Mount Weather and orders him to leave it behind. Abby tells him to not take out his anger on the guard and Kane responds that she put their entire summit agenda at risk by moving people into Mount Weather. Abby tries to excuse herself by saying she did it to save Nyko but Kane tells her opening a hospital is different than moving into the Mountain and now they will have to add that to the list of objectives for the summit meeting: lifting Lincoln's kill order, opening trade, and getting Clarke back. He quickly apologizes for using Clarke as a bargaining chip but Abby worries they will not get Clarke back.
Kane enters Polis, seeing it for the first time above-ground and is amazed at the sight. He wanders through a marketplace with Abby and their guards as they take in everything. A girl grabs Abby's hand and drags her to a kiosk where a woman is frying up some local food and offers a piece to Abby but Abby refuses. Kane happily accepts the food and offers the woman the patch off his jacket in exchange. Abby sees that Kane has a vision for their people and offers him the Chancellor's pin but he refuses, saying they should hold an election instead of passing the pin around. Indra arrives and welcomes them to the capitol.
Kane and Abby are in Lexa's bedroom, waiting for her to arrive. The door opens behind them and Clarke walks in. Abby is overjoyed to see her and hugs her. Clarke gets down to business and tells them the terms of the summit have changed because of the Ice Nation. They are no longer there for a treaty but to join the Coalition to avoid a war. Abby refuses and Clarke calls it their new Unity Day where the Sky People can either be the thirteenth station or the thirteenth clan. Abby asks for Kane's advice and he agrees with Clarke.
At sundown, the summit begins with the Grounder Anthem as Clarke strides into the throne room and takes a stand before Lexa. Clarke pauses in front of Lexa before dropping down on one knee and bowing to her. Roan is the first to bow to Lexa after Clarke and the rest of the people follow suit with Kane and Abby and the rest of the Skaikru as the last kneel. Lexa orders everyone to rise and welcomes the Skaikru and Clarke to the summit. She tells the rest of the clans she is initiating them into the Coalition and the leader of the Skaikru will bear the mark. Abby passes the leadership over to Kane and he offers his forearm to be branded with the mark of the Coalition.
Octavia, Bellamy, and Pike barge in, holding a guard captive. Bellamy warns everyone the summit is a trap. Ivon, the Ice Nation representative, tells them it was the Skaikru who barged into the summit with guns. Pike says they are right because two Skaikru guards are already dead. Lexa asks how they came by the information and Octavia realizes Echo is no longer with them. Bellamy realizes Echo betrayed them as Kane tells him to stand down. Raven comes across the radio and tells them that the Grounders attacked Mount Weather and it is completely gone with only her and Sinclair surviving. Ivon tells them that is what they get for moving their people back into Mount Weather and the Ice Nation did what Lexa was too weak to do. Lexa declares war and orders the Ice Nation delegation along with Prince Roan to be arrested. Abby worries that Arkadia might be under attack next and Lexa commands them to go. Indra offers to escort them and tells Octavia she hopes she kept up on her training because she will need it before giving her back her sword.
In Watch the Thrones, Abby is first seen at a Council Meeting following the Ice Nation attack on Mount Weather. Pike is there as well as he asks her when they plan on retaliating for the attack. She says they won't be retaliating since the commander will bring them to justice. This clearly bothers Pike as he tries to prove her wrong but she simply ends the meeting. After everyone has left except her her and Kane she says that after the election "[Pike's] your problem."
Kane and Abby later attend the Mount Weather memorial when they are approached by Pike who tells them a grounder army is approaching Arkadia. Abby says that they already know since the army is a peacekeeping force that was sent by the commander to protect them. Later, Kane and Abby arrive to arrest Pike, Bellamy, and the surviving members of Farm Station who planned on massacring the army.
In Hakeldama, she is seen next to Kane wondering how the Farm Station survivors murdered an army of 300 and left no wounded. She is confronted by an angry Raven who she didn't clear medically, removing her from work, though Abby claims it was for her own good.
Abby later meets with Jaha who has returned to Arkadia. He tells her he has found the City of Light but she brushes him off. Later, she and Kane help Clarke and Octavia escape Arkadia after Bellamy tries to arrest them. Clarke asks her mother to come with her but Abby says she can't as she needed in Arkadia.
In Bitter Harvest, Abby is first checking on Raven who claims all her pain has disappeared. Since it appears that Raven is not on drugs, Abby allows her to return to work much to her delight. She finds Jasper watching Jaha distribute chips and requests he wait until she's run some tests on the chip before taking one himself.
Jackson approaches her in medical and says that Raven's test results are completely normal and the absence of her pain is not drug induced. Jackson comments that she seems disappointed by this result but Abby says she is simply surprised. Jackson makes a comment about hope as Kane enters medical. She tells him to go check out the grounder patients in lock-up and to report back to her. He then leaves her and Kane. Kane approaches her and expresses his worries over Pike, Bellamy, and Octavia. Abby comforts him by telling him that the members of the 100 are no longer just kids and kisses him on the cheek in order to give him hope.
She finds Jasper sitting with Jaha and about to take the chip which she catches just before he swallows it. Abby asks Jaha if he would've given the chip to Wells without testing it first and Jaha seems confused much to Abby's horror. She tells him she's shutting him down and confiscates his bag of chips before leaving.
In Stealing Fire, Abby is devastated about Kane's upcoming execution and visits him before it. She insists upon helping him escape while he begs her not to do so. Abby admits that "[She] can't do this again", in reference to her husband late Jake. They share a brief intimate moment before he tells her not to make this any harder for him than it already is and he is taken away by the guards.
Later, Abby enters the prisoner's room and undoes Kane's handcuffs. When all the prisoners are exiting through the hatch and Kane tells Abby she's next she admits she won't be coming with him. She says that Arkadia needs her to "show them the way out of the dark." In response, Kane kisses her passionately and tells her "May we meet again" to which she responds "We will" before exiting the room.
In Fallen, Abby approaches Raven's door to find Jaha. She orders that he leave but Jaha refuses and says that Raven is with them now. As a few of Jaha's chipped followers approach Abby orders they leave and they listen to her and Abby is able to enter Raven's room.
Raven is with Jasper and Abby and tells Abby she thinks she knows how to get A.L.I.E. out of her head, she just needs one of the wristbands Abby sent to Earth with the 100. Abby goes to tell Raven where it is but Raven stops her saying everything she hears ALIE will hear as well. Abby tells Jasper the location of the wristband and he goes to find it as Raven starts screaming. Abby carries a screaming Raven to medical and asks for a sedative to knock her out. Raven continues to scream as she relives her painful memories before entirely submitting to ALIE. Abby is angry that Jackson didn't help her but he instead plunges a syringe into her neck knocking her out.
Abby awakens with her hands bound behind a chair, with Jaha, Raven, and Jackson hovering over her. Jackson tries to convince her to take the key saying that as doctors they should be supportive of this miracle pain reliever. Abby responds by asking Jackson about his mother who the chip has erased from his memory. Jaha decides to try harder to convince Abby to take the chip but Abby claims that even if they torture her she will never do it. Instead, they use Raven and make her slit her own wrists and Jaha tells Abby she can save Raven if she takes the key. Abby begs Jaha but he refuses until she finally agrees to take the chip and allowed to help Raven. Abby is later seen with Jaha distributing chips to Arkadians claiming that as she took it herself, everything Jaha said is true.
In Join or Die, Abby approaches Jaha in Polis and tells him to leave Kane to her when he dragged off as a prisoner. She later enters the room and tricks Kane into thinking she is unchipped. She tells him ALIE is looking for Clarke and tries to get him to give her Clarke's whereabouts. When she is unsuccessful, ALIE demands she try harder and she does by kissing Kane and pushing him onto a bed. However, by then Kane has already determined she is chipped and she orders he be crucified. She later watches unsympathetically as Kane is nailed to a cross. When Jaha points a gun at her head in an effort to convince Kane to take the key, she seems emotionless and unaware.
Abby is seen in a flashback on the Ark with Jaha when Pike is told he'll have to teach Earth Skills to the delinquents. She is later standing next to Kane as the members of the 100 board the dropship. Clarke is carried by a stretcher and she says goodbye to her. Kane apologizes to Abby about Clarke but she simply retorts back, "you got your extra air."
In Perverse Instantiation (Part 1), Abby and Jaha bring Clarke to the Polis tower and try and convince her to give them the passphrase for the flame. When Clarke refuses, Abby takes a scalpel and begins torturing her daughter by stabbing her in the chest in order to try and get her to talk. When Clarke says nothing, ALIE forces Abby to hang herself to again try and get the information out of Clarke. Luckily, Murphy arrives in time to cut Abby's noose saving her life.
In Perverse Instantiation (Part 2), Clarke uses the EMP on her mother destroying the chips. Upon waking up, Abby is horrified at what she has done under ALIE's influence and Clarke convinces her it was not her fault. Clarke then protects Abby from Bellamy, Pike, and Octavia and tells them she used the EMP and her mother is back. Murphy asks what they are going to do about Ontari and Clarke says that since Ontari is brain dead she can not be given the flame so instead Clarke will be putting the flame in her own head. She says that if she connects herself to Ontari the flame shouldn't harm her. At first, Abby refuses saying it's too dangerous but she eventually agrees when she realizes her daughter is right, it's their only choice.
She hooks Clarke up to Ontari and when enough nightblood is in her body allows Murphy to insert the flame into her neck. Clarke screams and Abby demands Murphy remove the flame but Clarke recovers quickly and insists that the flame stay. She says she now know how to stop ALIE. Clarke says she needs to enter the City of Light. Abby seems hesitant at first but she eventually agrees. While Clarke is in the City of Light, Abby watches as Ontari begins seizing and she performs chest compressions on her since if Clarke doesn't get enough nightblood, the flame will kill her. When Clarke begins seizing, Abby realizes Clarke isn't getting enough nightblood and she cuts open Ontari's chest and tells Murphy he'll have to pump Ontari's heart in order to keep Clare alive.
She watches the chipped victims enter the room and is forced to shoot a grounder who comes towards Clarke. Once Clarke has pulled the kill switch and the City of Light is destroyed, she unhooks her daughter from Ontari and helps her remove the flame. Abby then notices Kane is sobbing into his hands Clarke tells her to go to him insisting that she is ok. Abby approaches Kane and embraces him as he sobs into her arms.
In Adjustment Protocol, Abby is horrified when it appears that Josephine Lightbourne had permanent control of Clarke's body while Clarke is apparently dead. Abby vows revenge upon Russell Lightbourne who understands her pain and anger. Clarke later reveals the truth to Abby, Jackson and Raven. To protect Madi, Abby turns herself into a Nightblood to get the remaining doses of bone marrow. Abby and Raven subsequently make amends before Russell arrives with the newly-resurrected Primes. Abby realizes that Russell intends to make her the last host and orders the others to stand down, accepting her fate. As her friends struggle with the Sanctum guards, Russell injects Abby with the mind-wiping drug. In her final moments, Abby flashes back upon her husband, Marcus Kane and her daughter.
Clarke is later horrified to discover that Abby is dead and has become the new host of Simone Lightbourne. Simone mistakes Clarke's grief for Abby as being over seeing Gabriel Santiago again following his betrayal. Abby's murder also pushes Murphy and Emori to reject the Primes completely.
In The Blood of Sanctum, Clarke hopes that Abby survived the same way she did through A.L.I.E.'s neural mesh, but Russell confirms that Abby's was gone after the EMP, having checked before implanting Simone in her body. During a confrontation between Clarke, Simone and the Masons, Simone suddenly turns on the other Primes, claiming to have really been Abby pretending to be Simone all along. However, when Simone can't name Jake, Clarke floats the Primes, killing them. Simone manages to grab onto Clarke, but after sadly staring at her mother's body for a moment, Clarke pushes Simone off of her. Simone and Abby are blown into space, killing Simone and Abby's body. Abby's body is seen floating into deep space as a devastated Russell looks out the bridge window. Clarke later tells Bellamy that she tried to do the right thing before she lost Abby.
In From the Ashes, Clarke is shown to still be reeling from the death of her mother though she claims to be fine. When Clarke and her friends raise a toast to Abby, a traumatized Jackson knocks Murphy's glass, feeling like that Murphy was involved with Abby's death. Murphy insists that he had no idea what Russell intended to do and Clarke diffuses the situation, stating that she believes Murphy. However, Murphy continues to suffer from guilt, blaming his actions for Abby's demise. Madi later tries to comfort Clarke as she also had her mother die in her arms, but Clarke states that it was Simone she floated and Abby was already dead.
Later, Russell returns Abby's belongings to Clarke which had been removed by Simone when she was resurrected in an effort to goad Clarke into killing him. Holding Abby's ring, Clarke snaps and beats Russell severely before threatening him at gunpoint. However, Clarke knocks Russell unconscious instead and cries over Abby's belongings. Unaware that Russell has been killed and replaced by Sheidheda, Clarke prepares to leave him to burn in the palace while she departs with Abby's belongings, but is convinced to save him instead. Taking Sheidheda outside, the still-enraged Clarke announces the execution of "Russell" the next day for his crimes.
In Welcome to Bardo, Indra orders Jackson to remove Russell's Mind Drive without numbing the pain in order to prevent Sheidheda from ever being resurrected again. When Jackson is surprised that Indra doesn't want him to numb the pain, Indra tells him to let Sheidheda feel it "for Abby" and Jackson agrees.
In The Dying of the Light, after Madi takes off on her own to save everyone in the same way that Clarke often has, Clarke wonders if she made her mother feel the same way that she is currently feeling every time. Clarke tearfully states that she didn't meant to and Gaia reassures her that she's sure that Abby knew that just as Madi doesn't mean to hurt Clarke.
In The Last War, Clarke mentions seeing another person using her mother's face as part of her pain to the Judge. Later, the Judge takes on Abby's form when Raven takes the test and remains in that form until humanity passes the test and Transcends. The Judge notes that Abby's view of Raven means more to her than that of Raven's own mother and that Raven fears Abby's judgment.
Abby is a strong willed individual who tries to fight for what is right for her family and others.
She makes risky decisions, but in the end, she is always righteous in what she does and she is willing to face the consequences of her actions.
Abby has brown hair and brown eyes. She is often seen wearing jeans and a leather jacket.
In Season 5, after the 6 years and 7 days jump, her hair has white highlights.
Pilot, Abby tells her to be safe and that she loves her. After, Abby closely watches over Clarke's vitals. While on Earth, Clarke learns the truth about her mother's involvement in her father's death in Earth Kills. This causes a rift between Clarke and her mother. To punish her mother for her father's death, she takes her wristband off, letting Abby believe her to be dead. When Raven Reyes makes contact with the Ark in Contents Under Pressure, Clarke confronts her mother and tells her she knows the truth. Abby tries to apologizes explain his death was never supposed to happen. Clarke truly believes she will never be able to forgive her mother for turning in her father. When Clarke believes her mother to be dead in the Exodus ship crash, she is devastated.
When they are reunited in Human Trials, Clarke is happy to see her but their relationship is strained. The last time Abby saw Clarke she was her little girl and she has a hard time accepting how changed Clarke is. Clarke goes behind Abby's back to the point of usurping her authority on numerous occasions. Abby often disagrees with the decisions Clarke makes in regards to the people. Tensions escalate in Coup de Grâce when Clarke tells her mother that even though Abby is the Chancellor, Clarke is the one in charge. In Resurrection, when Abby finds out that Clarke knew ahead of time about the bombing of Tondc, she is appalled that her daughter would do such a thing and begs her to not forget they are the good guys. By Blood Must Have Blood (Part 2), Abby has come to realize the difficult choices her daughter has had to make are not so different than the choices she made on the Council and tells her daughter that maybe there are no good guys.
Abby and Clarke are reunited in Ye Who Enter Here when Abby and Marcus Kane travel to Polis to negotiate a peace treaty. When Azgeda blows up Mount Weather, Abby returns to Arkadia while Clarke stays in Polis to represent Skaikru. Abby and Clarke meet again in Perverse Instantiation (Part 1). At this point Abby has taken the chip and become a member of A.L.I.E.'s Cult, she tortures Clarke so she will tell them where the A.L.I.E. 2.0 is. When she refuses Abby hangs herself in order to force a confession, Clarke still will not divulge the location of A.L.I.E. 2.0. In Perverse Instantiation (Part 2) Clarke uses the EMP to fry Abby's chip. Abby helps connect Clarke to Ontari so Clarke may enter to the City of Light and defeat A.L.I.E.. While Clarke is in the City of Light Abby protects her daughter.
In The Dark Year, Abby revealed that she was responsible for the cannibalism, during the "Dark Year" in the Second Dawn Bunker and for Octavia's dark nature. However, out of altruistic reasons, it appears that Clarke does not hate her for it and forgives her for her decisions, suggesting that she only hated Abby for killing her family member, which was her father.
In Adjustment Protocol, Abby is reduced to immediate tears at the idea that Clarke is truly dead and threatens to kill Russell Lightbourne over her loss, something that Russell believes as one parent to another. Abby is later overjoyed to learn that Clarke has survived. In turn, Clarke is devastated when Abby is mind wiped to become the new host to Simone Lightbourne. Clarke holds out hope that Abby survived in The Blood of Sanctum, but accepts the truth after Russell confirms that her neural mesh is gone. Though Simone tries to trick Clarke by pretending to be Abby, Clarke is able to see through it and decides to float everybody in the corridor, Simone included. Though Simone hangs onto Clarke who has the chance to possibly save her, Clarke accepts that her mother is truly gone and after looking at Simone and thus Abby's body for a final moment, pushes Simone off of her so that she will be floated, taking Abby's body with her.In From the Ashes, Clarke nearly kills Russell after he returns Abby's belongings to her, something that Russell had intended. In False Gods, in lieu of a body, Clarke buries Abby's wedding ring as a form of funeral with Gaia burying the dead Flame with her.
The Ark was dying, Abby tries to convince him not to because she knows he will be floated. She turns to their friend, Jaha, in the hope that he will talk him out of it, but her telling Jaha of her husband's plans leads to Jake's execution. This devastates both Abby and also her daughter Clarke Griffin. However, while Abby knows the truth about Jake's death and blames herself, Clarke thinks it was the fault of Wells Jaha, who she told Jake's plan to in confidence. When Wells tells Clarke the truth, she is angry at her mother, but when the Exodus ship Clarke thinks Abby was on is crashed by Mount Weather, Clarke is distraught. When the two reunite in Human Trials, Clarke shows no anger towards her mother because she is so relieved to find Abby is alive. While Clarke may not have completely forgiven Abby, their relationship is mostly healed. In Adjustment Protocol, Jake is one of her last thoughts as Abby is mind wiped.
the Ark, Abby and Marcus Kane constantly had opposing views. Kane saw Abigail as a threat to his goals and frequently had her arrested and even almost floated her once due to his strict rule-following and her bending of the rules. Later, in The Calm, he seems to start caring for Abby, saving her life when he is exploring the other deck to look for survivors. On Earth, Marcus is the first person to follow Abby out of the Ark ship once it lands.
In The 48, they go out looking for the Camp of the Delinquents and Clarke together. When Abby gives guns to the Delinquents to help them escape and look for Clarke and the others, Marcus sentences her to shock-lashing in Reapercussions before passing along the Chancellorship to Abby. In Resurrection, Abby finds Marcus trapped under rubble after the missile on Tondc, pulling on a piece of metal to make noise and she grabs his hand to stop him. Abby tries to help him and he tells her to leave him and go find Clarke until Abby explains that Clarke got out as she already knew about the attack. When rocks fall down and trap them both further, they talk about how their actions on the Ark have influenced Clarke and the sins they have to answer for. In Blood Must Have Blood (Part 2), after they are captured by Mount Weather and Abby has her bone marrow extracted, they return to Camp Jaha, holding hands.
In Bitter Harvest, Abby kisses Marcus on the cheek, in order to give him "hope". In Stealing Fire Marcus is to be executed by Pike but is freed by Harper, Miller, Bryan, Octavia, and Abby and has to flee Arkadia. Abby decides to stay behind. In response, he kisses her passionately. The two then do not meet again until Join or Die, when Marcus goes to Polis. Abby pretends to be unchipped in order to obtain Clarke's whereabouts from Marcus. She seduces him, but he realizes it's not her. Abby has him crucified for his resistance. However, Marcus' defiance wavers when Jaha threatens to kill Abby, and he takes the chip for her. Later, in Perverse Instantiation (Part 2), they reunite at the end after Clarke shuts down the City of Light. Abby and Marcus share an embrace while crying, to comfort each other.
In Heavy Lies the Crown Abby and Kane sleep together. They spend the majority of the season separated from one another. In The Other Side Abby learns that Kane has been locked outside of the bunker. Abby and Bellamy Blake work together to open the bunker door. As a result only 100 members of Skaikru can remain in the bunker. Abby says she will be outside during Praimfaya. When Kane protests she tells him that she loves him, but she has made her decision. Kane does not follow Abby's wishes, and keeps her inside the bunker.In Season Six, Abby does everything she can to save Kane, even going so far as to make a deal with the Primes to resurrect Kane via a Mind Drive which requires the sacrifice of a young man named Gavin. However, Kane is unable to live with himself in this state and believes that Abby won't be able to live with herself either. Kane chooses to float himself, telling the devastated Abby that it is how they begin to do right again. In her final moments, Abby remembers Kane alongside her husband and daughter.
Raven was a regular patient of Abigail Griffin on the Ark and their relation became stronger as Abby needed Raven's help to go herself back to Earth. They later declared that they were family.In "The Old Man and the Anomaly" Raven agreed to do a spacewalk to create the Nightblood serum as a favor to save Abby's life and as a payback for Abby's support to Raven in the past. However, she makes it clear that she is still angry with Abby over her decisions. The two women make amends shortly before Abby's death in "Adjustment Protocol."
John MurphyDuring their interactions, Murphy and Abby are shown to be friends and allies. Murphy even risks his life in "Sic Semper Tyrannis" to help Marcus Kane save Abby. However, in Season Six, Murphy's deal with Josephine Lightbourne leads to him helping the Prime to manipulate Abby into making new Nightblood. After getting the new Nightblood, Russell Lightbourne sacrifices Abby to resurrect his deceased wife Simone Lightbourne. In Season Seven, Murphy is shown to carry enormous guilt over Abby's death, believing himself to be responsible for it when Emori and even Clarke don't blame him.
Michael VinsonAbby's relationship with Michael Vinson was ultimately an abusive one with Vinson developing an obsessive infatuation with her and becoming Abby's drug dealer to have leverage over her. After Abby got clean, Vinson was unwilling to let her go and attempted to murder Marcus Kane in order to use her grief to drive Abby back into addiction and dependence upon him. However, Abby killed Vinson for his actions upon discovering what he was doing.

- -- in Pilot
- Abby Griffin: "We always have a choice, Kane. You chose to press charges against my husband, your friend, even though you knew he would get floated for it. You chose to include my daughter in those charges, and now you're choosing this. Hiding behind the law absolves you of nothing."

- Abby Griffin: "You don't have to justify yourself, I broke the rules and accept the consequences. But you can lash me 100 times and I will still do whatever it takes to find those kids, my kid."
- -- in Reapercussions
- Abby Griffin: "And where's Marcus now? Imprisoned still? You're just going to leave him there? Like the kids in Mount Weather? If we run, who's going to rescue them?"
- Thelonious Jaha: "You weren't there, Abby. I saw them. Warriors trained since childhood to fight and die for their cause. As we speak, they are marching on this camp. And trust me when I tell you, the right choice is to live so that we can come back and fight another day."
- -- in Long Into an Abyss

- Marcus Kane: "It's amazing. When I dreamt of the ground, it was empty."
- Abby Griffin: "But it's not empty now. Marcus, you gave this to me, you asked me to set a good example, but what we're trying to do here is something new, something... Something you have a vision for. This should be yours."

- Abby Griffin: "Why would I start listening to you now?"
- -- in Stealing Fire
- Abby Griffin: "Clarke, listen to me. A.L.I.E. wants the Flame. If you take the chip you're giving it to her. The second someone sees you, A.L.I.E. is going to know you're there. She'll kill you. If your mind dies, you die."

- Abby Griffin: "Marcus, please. We are so close. We can make a new life. We can start over."
- Marcus Kane: "Not like this. You told me once that your job was to make sure that we deserve to survive. You remember? (Abby nods) That's what I'm doing now."
- Abby Griffin: "No, please. I can't do this on my own."
- Marcus Kane: "Yes, you can, Abby. You're so strong. You're so much stronger than me. You saved me so many times. Not just my life, me."
- Abby Griffin: "I need you. I love you."
- Marcus Kane: "I love you, too. I love you more than I ever thought I could love anyone. But if I don't do this now, then we both live to regret it, and so many more innocent lives will be lost. This is how we get our humanity back."
