Marcus Kane

Marcus Kane is a major character in the first, second, third, fourth, fifth and sixth seasons. He is portrayed by starring cast member Henry Ian Cusick and debuts in the series premiere.

Kane was a Council member on the Ark and Chancellor of Camp Jaha before his departure. Kane was on the Council when they decided to send the 100 to Earth and when they decided to cull 320 Ark citizens to save oxygen.

Once the Ark came to Earth, Kane helped establish Camp Jaha as its first Chancellor before passing along the Chancellorship to Abigail Griffin when he left on a mission to seek peace with the Grounders. After his return to Camp Jaha, he often sided with Clarke Griffin and worked as an emissary between the Sky People and the Grounders.

After Abby decided to step down as Chancellor, Kane was supposed to be elected the new Chancellor of Arkadia, but he lost the impromptu election to Charles Pike. Seeing Pike's tyrannical way of running things, Kane lead a small rebellion against Pike to attempt to restore order to Arkadia. Kane was captured and sentenced to death by Pike but managed to escape to safety, leaving Lincoln behind to be executed by Pike. He and his group later secured Pike's capture. Kane went with Pike to Polis but discovered that A.L.I.E. had taken over most of the city. Kane was forced into taking the chip after A.L.I.E. threatens Abby's life. He is later freed after Clarke activated A.L.I.E's kill switch.

Throughout the fourth season, Kane tries to maintain the peace between the Thirteen Clan, sleeps with Abby and becomes her boyfriend. Then he convinced Thelonious to never rebel against the Grounders, stating that he already saved humanity, which are 1,100 Grounders. As a result, Kane and Jaha started the Second Culling in the bunker to stop the riot and secure the survival of humanity and all survivors become Wonkru, one clan with Octavia Blake as their leader.

During the fifth season, he struggled to stop Abby from taking pills, he left with Abby to go to Shallow Valley with Charmaine Diyoza and the Eligius prisoners. While there, he helped Diyoza, giving her advice and tips about Octavia. He talked about their mistakes in the past and hoped that Diyoza wouldn't do the same mistakes. He tried to convince her that prisoners need Wonkru to survive. He convinced her and she brought the defectors to the valley. He also met Michael Vinson who, almost kills him and left him in a coma following Vinson's attack.

During the sixth season, Kane is still suffering neck injuries from Vinson. He is put into cryo after a throwing up blood due a heated argument with Octavia.

Early Life
Marcus Kane was born on the Ark to Vera Kane and later become a member of The Council, where he became acting Chancellor when Thelonious Jaha was shot and again when Jaha remained behind on the Ark when the rest of the Sky People went to Earth.

When Jake Griffin decided to defy the Council about the air shortage and go public, Kane pressed charges against him and included his daughter, Clarke Griffin, in those charges.

Throughout the Series

 * -|Season One=

In Pilot, Kane is first seen in The Ark's control room to monitor the delinquents statuses. Two Delinquents have appeared to have already died but are believed to have died from the crash landing rather than radiation. Afterward, he is seen speaking with Commander Shumway, who says that the chancellor had been shot, and the prime suspect behind it was Bellamy Blake. Kane says that this must mean they have a traitor among them, as Bellamy Blake disappeared after the chancellor's shooting, meaning that someone helped him escape onto the delinquent's dropship. When returning to the control room, Abigail Griffin and he discusses how John Murphy and John Mbege have both suddenly died. Kane says it was out of radiation, but Abigail Griffin argues that people just don't randomly die without signs of them dying first.

After Abby gives Thelonious Jaha, the Chancellor more medical supplies than the Ark's limit, Kane arrests her. Kane says she will be executed for her crime, but Abby says she did this to ensure he will never become Chancellor. Callie Cartwig, Abby's best friend confronts Kane and tells him to let her go, which Kane refuses saying the penalty will stay.

Before execution, Abby gives her goodbyes and tells everyone good luck. Right after Kane gives the order, Jaha bursts out of nowhere stating that Abigail will be freed. Kane in shock seeing the Chancellor alive is told by Jaha that he will be dealt with later.

In Earth Skills, he is called upon by Jaha in his room, where he and Abby are having a conversation. Abby is dismissed and Kane closes the door. Jaha asks him who would benefit from his death, but Kane tells him to get to the point. Jaha says he is the prime suspect of his attempted assassination, but Kane says he had nothing to do with it. Later, Kane is seen discussing The Culling with other Council members, an event that would kill hundreds in order to extend the Ark's oxygen supply.

When the council is brought together, Kane and two other council members argue that The Culling must take place in order to preserve life on The Ark. Abby and the others argue however that they need to see if the Delinquents can survive on Earth before doing anything. When the vote towards the culling comes to a tie, Jaha is left to make the final decision. Jaha says he will abstain, which infuriates Kane, causing him to bang the table and storm out of the Council room.

Kane can later be seen alongside other Sky People as they watch the Delinquent number slowly go down.

In Earth Kills, Kane is mentioned during a flashback when Abigail Griffin talks to Jake Griffin about the oxygen issue and whether or not he should make the information public. Jake says she sounds like Kane, to which she answers "Because he's right."

In Murphy's Law, Kane is first seen speaking to Abby as they walk past each other in the halls. Kane asks Abby why she has been visiting Mecha Station so often, but Abby does not give him a straight forward answer. Kane asks her to keep him updated.

Nygel eventually asks Kane to come down and meet her while she is playing a game of chess. Kane passes by his mother Vera Kane, who is preaching to her church about how they will one day return to Earth. Vera asks him if he is there for the church, but Nygel answers her question and tells Vera he is there for her. Nygel then informs Kane that Abby took an illegal tool for unknown uses. Kane asks for evidence, which Nygel shows.

As Kane arrests Abby for her crime, a pod is seen launching, revealing Abby distracted Kane in order to allow Raven Reyes to escape down to Earth.

In Twilight's Last Gleaming, he is seen speaking with Abby about The Culling, and how The Council has made up their mind, deciding to go through with it, which angers Abby. After telling Abby about the decision, Kane goes to Jaha to speak with him, asking for his confirmation on the Culling. Jaha confirms it and announces he will be joining the those in Section 17, claiming that at the time he would be doing an "inspection". Kane advises him not to, but Jaha says he cannot choose the fate of others if he cannot choose the fate of himself.

Kane is later informed by Commander Shumway that a video of Jake Griffin, Abby's husband, has surfaced and is broadcasted across The Ark by Abby. When the council is brought together to discuss this, Kane says riots are to occur, but to their surprise, there were hundreds of people outside the Council room trying to volunteer for the Culling in order to help their loved ones. This turn of events shocks Kane greatly. Despite this news, Jaha still claims he will participate in the Culling no matter what everyone says. Kane, however, manages to convince him that he must show leadership, and it was him, not Jake Griffin who brought the people together. His death would only cause more problems.

Kane later is watching those who are entering the room for the Culling. Kane informs Abby that he still believes the Delinquents are a lost cause. However, he says he will call off the Culling immediately if there is any word from Raven Reyes. Kane can later be seen alongside Jaha and Jacapo Sinclair. Despite everything, the Culling takes place and those who participated all die.

In Contents Under Pressure, Kane is first seen at a Council Meeting informing Abby that she will be spared for her crimes, but will be removed from The Council immediately. Suddenly, a transmission is heard. Raven Reyes is radioing in from the ground, revealing that The 100 are still alive and the ground is survivable. He is then seen staring at the Ark's last tree where his mother and other Sky People are having a memorial for those who took part in The Culling. Cuyler Ridley steps in and is furious with Kane as he is standing on the ground where his wife died. Kane tries to calm him down but Ridley attacks him. Jaha steps in to save him and tells the room to clear out. Kane is supposedly drinking, which Jaha comments on, telling him to get his act together.

There are arguments, but Jaha and Diana Sydney are able to calm them down. Kane is then seen returning to the room of the Culling where is his mother is. Vera comforts Kane who feels depressed and responsible for 320 who died.

In Unity Day, Kane is first seen at the Unity Day Celebration. An explosion occurs at the celebration, killing six people. When Kane is ordered by Jaha to figure out who caused it, Kane finds the body of his mother on the floor and impaled by a shard. Kane holds her in her final moments and recites the traveler's blessing. Afterward, Kane and several others are told to guard the Exodus Ship. While guarding it Diana Sydney walks up to Marcus and Abby and informs the two of them that Cuyler Ridley was behind the explosion, as revenge for his wife's death in The Culling. Kane thanks her and he is sent to interrogate Ridley.

While interrogating Ridley he is mocked by him, telling him there are more things happening than he thinks. Kane asks for answers, but Ridley gives none. Suddenly one of the guards protecting Kane uses his stun stick to attack another guard and Ridley kicks down Kane. Ridley and the guard then lock Kane and the other guard inside the interrogation room. Later when the area Kane is in loses heat, Jaha comes in to save him. Before Diana Sydney takes off with the Exodus Ship, Kane, Jaha, Jacapo Sinclair and many others make an attempt to stop her from taking it. However, when Diana reveals that not everyone will make it down to Earth, a man jumps on the ship, allowing the Exodus Doors they were trying to pry open to close. Afterward, Kane pulls back Jaha and the Exodus Ship takes off, turning off all power on the Ark.

In The Calm, Kane is first seen waking up after The Ark's catastrophic power failure. After scouring The Ark to find other survivors he comes across Kyle Wick, who was holding a door open with his arm on Sinclair's orders. Kane frees him with a tool and they move forward, only to come across more survivors. When Kane tries to make his way to Earth Monitoring station, he finds that the area is covered in rubble. Kane gets on the intercom with Jaha, who instructs him to take the survivors to the mess hall as that is where Earth Monitoring is pumping most power. Kane says he will not leave Jaha as him and the others in Earth Monitoring will die from lack of oxygen, but Jaha says to get his people to safety.

Kane disobeys Jaha, having him and the other survivors remove the rubble to break into the room. Kane and the others help those trapped in Earth Monitoring onto their feet and they continue their mission to helping other survivors. While discussing a way to fix things, Wick mentions that some people who were supposedly launched on the Exodus Ship might have survived, as Diana Sydney might have seen them as a threat and decided to kick them off the ship. Wick also mentions however that to get there they will have to crawl through a vent, which is very hot. Kane volunteers anyways in order to find the potential survivors.

Before entering, Wick tells Kane good luck and Kane crawls through the vent. Kane struggles throughout the entirety of the crawl but eventually, after kicking the other vent door open he makes his way to the other side, entering the Service Bay. Kane enters a room filled with survivors, one of which is Abby, who was believed to be dead. Kane holds Abby in relief.

In We Are Grounders (Part 1), Kane is seen at the Ark's meeting where Jaha discusses how everyone should use their final moments wisely as there are only 51 hours of oxygen left. Kane tries to get Jaha to keep looking for another way. Later, Kane can be seen working with Jacapo Sinclair, who asks Kane if he can go home to his wife. Jaha comes into the room and tells everyone if they use thrusters from the stations, this can bring them down to Earth. Kane asks if this is the right way, and Jaha asks if he has any better ideas.

In We Are Grounders (Part 2), Kane is seen in Earth Monitoring with other Sky People when Sinclair is explaining how The Ark will be brought to the ground. Kane explains how some stations will explode, and the unfortunate fact is some people will be on those stations. Kane is then seen strapped in his seat belt with other citizens as they get ready to launch. However, due to an error in the system, Sinclair says someone will have to launch it manually. Kane volunteers but just before leaving, Jaha launches The Ark in order to save his people. Kane's station lands on Earth successfully and he and Abby admire the beauty of Earth. Abby notices a smoke in the distance and tells Jaha she, Kane, and the others will go investigate it.

Once arriving at the camp, Kane enters the dropship and encounters the injured Raven Reyes and John Murphy.

In Inclement Weather, Kane puts Bellamy under interrogation, asking him about the Grounders and the type of weapons they use. When questioned on why he couldn't defeat the Grounders when the 100 had guns, Bellamy says that they might have if there were more bullets. Kane mentions that his men found more guns and ammunition in the underground bunker and Bellamy comments that he should have searched better. Major Byrne then appears with a restrained Murphy and Kane has him locked up with Bellamy.

Later, Kane is walking around in Camp Jaha when a cry is heard from the forest. He and others follow the sound and find three men who have been crucified to a tree. Back at Camp Jaha, he is looking over the bodies when he spots an uncovered hand of a body. He covers it and then continues into the medical area to ask about Raven. He tells Abby that the kids have one quality; courage. When asked if he sent out the search team, Kane says he takes the crucifixion warning seriously. He apologizes when Abby asks again and says he has made his decision.

In Reapercussions, Kane learns that Abby helped Bellamy and the others escape and gave them weapons. Under the encouragement of Major Byrne, he has her lashed with an electric baton, according to the laws laid down by the Exodus Charter. He also witnesses several guards bringing in a captured grounder and later interrogates the grounder with help from Major Byrne. However, he sends Byrne away once she threatens the grounder with violence when he refuses to speak. Kane says that there has to be a better way to handle the Grounders.

Later, after the lashing, Kane approaches Abby and gives his Chancellorship to her while he heads off on a mission to broker peace with the Grounders.

Eventually, he unties the grounder, but he is attacked and knocked out. Kane awakens and realizes he's being carried by other grounders. They throw him into an underground cell. After Kane gets back on his feet, he notices a man walking out of the shadows. The man is revealed to be Thelonious Jaha.

Suddenly, Gustus walks in with Lexa and a few other grounders to inform them that one of them must kill the other. If they are both still alive by sunrise, both of them will die. Gustus leaves Lexa in the room with Kane and Jaha as he leaves the room. Kane and Jaha continue to think of ways to make it back to the Sky People, but nothing smart comes to mind. Ultimately Kane tells Jaha to kill him, however, he refuses and Kane slits his arm. Lexa and Jaha step in to help Kane, and Jaha picks up the knife he was given by Gustus and holds it to Lexa's throat. When Gustus walks in and sees him, Lexa manages to escape his hold and reveals that she is actually the grounder commander, and only needed info from the two.

Later during the grounder feast, Kane offers Lexa alcohol as a gift to the grounders. However, after one of her loyal guards Gustus tries the alcohol, it appears to be poisoned and Gustus is rushed out of the room. Lexa states that no Sky Person was to leave the feast room, isolating even Lincoln in the room until they figure out who is responsible.

Marcus is then seen asking Clarke who she thought would have done this, however, she herself is clueless. Later the grounders decide that Raven Reyes is responsible, and they take her outside to perform their torture ritual. However, this is quickly stopped by Clarke, who manages to figure out that Gustus poisoned himself as he thought it would protect Lexa and end the alliance.

In Survival of the Fittest, he is seen in Camp Jaha gathering a group of grounders together to train with the Sky People.

 * -|Season Three =

In Wanheda (Part 1), Bellamy goes to see Kane about traveling to Sector 7 and Kane gives his consent, however, he tells Bellamy that the weapons brought along are for reinforcements only and enforces the "non-lethal" response rule. Kane also says that there hasn't been a Grounder attack in three months meaning they might finally be at peace and tells Bellamy not to screw that up. Bellamy agrees and leaves the room, and Abby wakes up from the couch in the corner of the room and gazes at the Sector map Kane has drawn, wondering if Clarke is in Sector 7. Kane offers to send out another search and rescue party but Abby says that Clarke will only be found if she wants to be found. David Miller interrupts their conversation and tells Kane that there were three clicks on the secure channel, meaning that "she" wants to meet with him. Later on, Kane meets up with Bellamy and Monty Green in Sector 4. Kane is with Indra. Bellamy starts to explain the killing of the Ice Nation warriors but Kane dismisses him, saying that they'll talk about it later. He tells the two that Indra has come to warn them about Clarke, and Indra states that Clarke is being hunted by everyone. The four take the rover to search for Clarke, and Indra explains Clarke's situation and suggests they start searching for her at the trading posts. They encounter a fallen tree and Indra warns everyone that it has been cut down, but Bellamy disagrees, stating they don't know for sure. As Bellamy begins to investigate, another tree falls behind them, trapping them.

In Wanheda (Part 2), Bellamy, Monty, Indra, and Kane have been trapped in Sector 7 in the rover for three hours waiting for something to happen. Bellamy pokes his head out the moon roof and suddenly has a knife to his throat. The rest of them are ordered out of the rover as Bellamy is yanked out through the moon-roof. Indra, Kane, and Monty are quickly taken hostage by what appear to be Ice Nation warriors who find the Farm Station beacon on Monty. Monty tries to fight them and Bellamy calls out his name to get him to stop. One of the warriors repeats Monty's name and Monty recognize her voice as his mother's. Monty's mother, Hannah, removes her face mask and she and Monty embrace. Charles Pike orders the rest of them to stand down and greets Kane and Bellamy. Monty asks where his dad is and Hannah tells him that he didn't make it. Kane asks Pike how many of them from Farm Station survived and Pike says only 63 have survived and the rest of them are camped in the mountains to the north. He calls them "Grounder killers" and everyone cheers, "Hoo-rah!" Bellamy interrupts and tells them they need to find Clarke. Pike recognizes Clarke's name as a former student of the Earth Skills class that he taught on the Ark. They go to move the trees blocking the rover and Bellamy asks Monty if he is okay. Monty replies that he has to be. Pike tells Kane that everyone from Farm Station survived the landing, three times as many as the 63 who are still alive. Indra tells Pike the Ice Nation can be ruthless and he should take pride in those he saved. Kane introduces Indra and Pike. They get the trees out of the way of the rover and Kane sends the Farm Station warriors to collect the rest of their people and head to Arkadia. Pike and Hannah go with Kane, Bellamy, and Monty after Clarke.

At the trading post, Niylah is getting beaten up and interrogated by Roan's bounty hunter partner as he asks her where Clarke and Roan went. He is about to cut off her hand when Bellamy shoots him dead. Indra tells Niylah in Trigedasleng they are there to help. Pike demands she speak in English and Kane orders him to scout the perimeters with Monty and Hannah. Bellamy pleads with Niylah to tell them about Clarke. Niylah recognizes him as Skaikru and tells him that Clarke was there last night and the bounty hunter told her his partner was Ice Nation. Bellamy thanks her as Monty comes back to tell them he found their tracks but they can't take the rover because there are too many trees.

They are walking through the same field where Clarke and Roan were previously. Indra calls for everyone to be quiet as they hear war drums coming from a distance. Indra recognizes them as Azgeda by the three dead scouts in the field. Pike tells everyone they need to get the bodies off the field before the army arrives or they will be blamed for it. Bellamy spots Roan and Clarke far on the other side of the field as Kane spots the incoming army advancing from another end of the field, separating them from Clarke. Monty points out a cave for them to hide in until the army passes through and Indra leaves to warn the Commander because the Ice Nation has just marched into Trikru lands. Indra warns Kane that if the Ice Queen gets Clarke first, she will die and they will all be at war.

Bellamy wants to go after Clarke but they are stuck in the cave with the corpses of the three Ice Nation scouts as they wait for the army to clear out. Monty asks Hannah what happened to his father. Hannah tells him how Farm Station landed in the snow, absorbing some of the impact. She starts crying and Pike takes over the story, telling Monty that the children were playing in the snow and were the first to die. Monty's father saved four of fifteen kids but was killed when he went back for the fifth and he died a hero. Kane tells Pike that not all Grounders are the same as the Ice Nation and Pike says they are to him. Later, Monty finishes telling them how forty-two people got out of Mount Weather alive and they did what they had to do. Pike tells Monty he did the right thing and asks if Mount Weather belongs to the Sky People now. Kane tells him they use it for supplies because of the established truce. Pike warns Kane the Grounders will break the truce and they need the Mountain. Monty notices that Bellamy had stolen a scout's uniform and was no longer in the cave. They find Bellamy limping along, still trying to follow after Clarke and Roan. Kane and Pike try to get Bellamy to give up but he is worried about losing Clarke. Monty convinces Bellamy to head back and try again later.

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 she refuses. Kane, however, 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.

Marcus 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 Marcus 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. Kane and the rest of the Skaikru then return to Arkadia as they fear it will be the next site of an attack. Clarke decides to stay behind in Polis with Lexa and Kane tells her to stay safe.

In Watch the Thrones, Kane is first seen at a council meeting with Pike and Abby following the attack on Mount Weather. Pike wants to retaliate against the grounders but both Marcus and Abby refuse, saying that the commander will bring the Ice Nation to justice. They both attend the Mount Weather memorial when Pike approaches informing them that an army of 300 grounders is approaching Arkadia. Kane tells Pike he already knows since Indra radioed and the army is, in fact, a peacekeeping force, sent to protect Arkadia from the threat of the Ice Nation. This causes anger among the citizens and one even throws a rock at Lincoln's head which breaks into a full out riot before Pike is able to end it.

Kane and Abby later arrive when Pike, Bellamy, Hannah and the other Farm Station survivors are trying to leave to go attack the army. He puts them in lock-up, however, Pike demands that he show the Arkadian's the brand mark on his arm. Kane obliges announcing that it is the brand mark of the Coalition symbolizing that they are the thirteenth clan and therefore are in this fight together. Pike, however, instead says it is much more resemblant of what farmers would do to their livestock before it was slaughtered. A Farm Station citizen then tells Pike he should run for Chancellor, which the vast majority respond to positively as they chant his name as he is led away.

The next morning, Kane arrives in lock-up and hands Pike the Chancellor's pin congratulating him on his victory in the election. Pike takes his first few actions as Chancellor which including freeing himself and the other Farm Station survivors, rejecting the brand mark of the Coalition and proceeding with the massacre. All the Farm Station follow Pike out of the cell but Kane stops Bellamy telling him it's not too late to choose the right side. To Kane's dismay, Bellamy says that he already has before following Pike.

In Hakeldama, Kane is seen standing next to Abby when Pike, Bellamy, and the other Farm Station survivors return from the massacre. They listen to Pike's speech and Abby seems horrified that Pike's regime was able to kill 300 but leave no wounded. Indra radios Kane asking him to come to the site of the massacre but knowing Pike is watching his every move, Kane sends Octavia instead. Kane catches Bellamy and berates him about murdering 300 warriors sent to protect them. Bellamy says that Trikru are a threat as they killed many of his friends before The Ark survivors even landed on the ground.

Kane meets with Jaha who is with Abby in medical following his return to Arkadia. Jaha claims to have found the City of Light but neither Kane nor Abby believes him. Abby asks Kane where his uniform is and he admits that Pike stripped him of his command. He later assists Abby in helping both Clarke and Octavia escape Arkadia after Bellamy tries to have them arrested.

In Bitter Harvest, Kane is first seen in contact with Octavia over radio. She is spying on Gillmer and Hannah when they spot a grounder kid. Gillmer and Hannah chase the kid trying to kill him but Octavia cuts them off and saves the kid's life. She radios back Kane and says they need to find out what Pike's regime is up to, as they were willing to kill a kid to keep it hidden.

Nathan Miller is helping Kane bug the Chancellor's office while Kane goes to distract Pike. He tells Pike they need to stop the distribution of the Jaha's chips but Pike says that that's Abby field, not his. Pike begins to walk towards his office when Kane stops him again mentioning the grounder prisoners. Pike claims they are a liability which is why he won't set them free. Kane insists that not all grounders are the enemy but Pike tells him they've already been through this and election decided what the majority of Arkadians think. Realizing he's stalled Pike for long enough, Kane sarcastically tells him to keep up the good work leaving him to go to his office. Kane later finds Pike's regime in the hangar bay and again tries to convince Bellamy to choose the right side. Bellamy, however, brushes Kane off again before getting into the rover with the other members of Pike's regime and driving off.

Later that day, Kane enters medical. He finds Abby and tells her he blames himself for Pike's Chancellorship and expresses his fear over the safety of the kids. Abby reassures him that the 100 are no longer just kids and seeing that he is stressed she kisses him on the cheek in order to give him hope.

Following the failed attack on the grounder village, Pike is conferencing with Bellamy. They both know that someone told Octavia who in turn warned the grounders. Both Pike and Bellamy know it is Kane but they have no proof and therefore can not arrest him. Pike dismisses Bellamy and tells him to find proof.

In Terms and Conditions, Kane is first seen listening in on a council meeting with Nathan Miller and Harper McIntyre. Kane is still trying to find a peaceful solution but Harper suggests just kidnapping Pike and handing him over to the grounders. Kane refuses and says that it's not who they are. Kane enters while Pike and his team and sorting through their ammunition storage saying he'd like to talk to Pike. He leads Pike outside and tells him that he needs to turn himself in. Pike refuses and says that he is leading Arkadia to victory.

Kane, Miller, and Harper listen in on another council meeting and are in horror when they overhear Pike's regime will be destroying another grounder village, unaware this a trick set up by Pike since he is aware they are listening in. Kane meets with Jacapo Sinclair and they plan to disable to rover however, they are unaware that the conversation was overheard by Monty. Sinclair sets the plan in motion but he is caught and arrested by Bellamy. Sinclair is interrogated but he says nothing before he is brought to lock-up and tells Lincoln to get ready for Kane's plan.

Bellamy meets with Kane where Kane again tries to convince him to change sides but Bellamy refuses and says that was exactly the same reason he met with Kane, to try and convince him to change sides. Bellamy is called to lock-up and leaves. Pike meets with Kane while Bellamy tries to get information from Sinclair. When Sinclair requests immunity from Bellamy and begins telling him of the plan Lincoln comes forward and begins beating him. Bellamy enters the cell and a full riot breaks out. All the guards are called to lock-up leaving Kane and Pike alone. Kane takes the opportunity to shock Pike, knocking him out before kidnapping him and placing him the rover. Harper radios Kane and tells him the plan is working, however, Monty overhears the conversation through Miller's bug and tells Bellamy to go for the main gate. There, Bellamy stops in front of the rover preventing Kane from going any further. Bellamy refuses to budge and Kane is forced to surrender himself to the guards.

Later, Kane is being interrogated by Pike. Pike asks him if he has anything to say for himself. Kane states that he admires Pike's dedication to rule of law but begs him to look beyond the rules. Pike refuses and sentences Kane to death. Bellamy seems shocked and as Kane is led away to a cell, Bellamy asks Pike if they're really killing their own people now. Pike claims that Kane's execution will serve as an example and hopefully will convince other's to join his side.

In Stealing Fire, Kane is seen in lock-up alongside Lincoln, Jacapo Sinclair, and the other grounder prisoners. When Pike arrives, he sentences Lincoln and Sinclair to death as well. Kane is later taken to see Abby before his execution. She says she won't let it happen but he begs her not to save him since he fears her life would be put in danger in doing so. Abby reveals her affection for Kane when she cradles his face and tells him "[she] can't do this again," in reference to her late husband Jake. Kane pries her hands off him before telling her to not make this any harder than it already is. He then calls for the guards and is taken away.

Back in the cell, Pike arrives to take Lincoln, Kane, and Sinclair. He places them in a room and orders the guards to shoot anyone who comes near. However, the prisoner's hide under the floorboards so when Pike arrives it appears they are already gone. The guards are also drugged and Pike realizes he walked the prisoners right into their master plan. Abby enters the room and undoes Kane's handcuffs as Octavia coordinates the escape with Harper McIntyre over the radio. Monty and his mother overhear them but Monty redirects the guards to the main gate in order to allow the prisoners to escape. As the prisoners are all leaving Arkadia, Kane turns to Abby and she tells him she isn't leaving with them as she is needed in Arkadia. In response, he kisses her passionately and tells her "May we meet again." Abby leaves and Kane overhears Pike's message on the radio saying that if the prisoners do not turn themselves in the sick grounders will be killed. Lincoln turns himself in and hands Kane Octavia so they can escape Arkadia. Later, as the resistance is leaving Arkadia, Lincoln's execution is taking place. Octavia awakens and crawls forward to watch it, Kane stands behind her as she watches Pike shoot Lincoln in the head.

In Fallen, Kane and the resistance enter Lincoln's cave. When Bellamy asks where Lincoln is, Octavia angrily says that he is dead before proceeding to beat her brother. Kane tries to intervene to stop it but Bellamy refuses his help and allows Octavia to continue beating him. Later, Monty radios Bellamy and tells him he's in trouble, Kane is hesitant to respond since he believes it's a trap set up by Pike but Bellamy convinces him otherwise. The resistance agrees to meet Monty at the dropship, still wary about Pike, however, Kane refuses to bring the entire resistance. He initially plans on going alone however, Octavia offers him an ultimatum. They then both agree to bring Bellamy as a hostage so they have someone to trade for Monty.

Bellamy, Octavia, and Kane arrive at the dropship and find it deserted. Bellamy assumes they arrived first but Octavia knows they didn't and calls for Pike to come out. Monty emerges, Pike behind him with a gun to his head. Pike tells them to put down their weapons since Kane can't shoot Pike since Monty would be in the shot. Kane puts down his gun and surrenders while Octavia fights back. Pike goes to untie Bellamy and Bellamy agrees to lead him to the rest of the resistance. Furious, Octavia goes to attack her brother but she is shocked and knocked out.

Bellamy is leading Pike who has Kane and Octavia prisoner to the resistance's camp. However, as they approach the blockade line, Bellamy betrays Pike calling for the grounders of the blockade to take him. The grounders kill Pike's guards and take him prisoner. Pike tells Bellamy he's doomed them all. Octavia prepares to kill but Kane tells her not to. He says that since the grounders didn't get justice for Finn Collins, they'll need justice for Pike. The grounders decide on taking Pike to Polis and Kane offers to come along saying that they are the thirteenth clan and he has the mark of the Coalition. The grounders begrudgingly agree and tell him to not slow them down. He tells Octavia and Monty to return to Arkadia, and tells them to tell Abby he'll look out for Clarke in Polis. Before leaving, Kane asks Bellamy if he turned in Pike for his sister or because he knew it was the right thing but Bellamy simply brushes him off. Kane then walks off into the distance following the grounders.

In Join or Die, Kane is seen entering Polis with the grounders and Pike. He is shocked to see that Polis is completely decimated and adorned with crosses where dying and dead grounders are laying. Jaha approaches and offers Kane the key to the City of Light but he refuses, throwing it off into the distance. A bag is put over his head and Kane is dragged off as a prisoner. However, Abby approaches Jaha and requests he leave Kane to her instead.

Kane is later seen in the Polis tower when a chipped Abby enters pretending to be unchipped in an effort of gaining Clarke's whereabouts. When Kane gives no useful information, A.L.I.E. Abby is instructed to try harder. In order to do so, she attempts to seduce Kane by passionately kissing him and throwing him down onto a bed. However, by this point he has already discovered she is chipped. Abby orders he be crucified while he begs for her to wake up.

Kane is also seen in the flashbacks on The Ark when he brings Pike to Chancellor Jaha and Abby when Pike is told that he will be teaching Earth Skills to delinquents. He is also forced to intervene when Pike begins hitting Murphy and attacking the other delinquents, however, he assumes that it was the kids and not Pike who had started the brawl. He also stands beside Abby while the 100 board the dropship and watches her say farewell to Clarke. He apologizes to her but Abby simply retorts, "you got your extra air."

Kane is seen on the cross still refusing to give Jaha any information. Kane begs Jaha just to shoot him and get it over with, however, Jaha claims if he shoots Kane he won't get what he's looking for and instead he points the gun at Abby. Upon seeing Abby's life in danger, Kane immediately agrees to take the key which Jaha happily gives him.

In Perverse Instantiation (Part 1), he shoots Roan and allows for Clarke to be taken by Jaha. He then ambushes, Pike, Indra, Miller, Bryan, and Octavia and shoots Pike and Bryan. However, he is unaware they have planted a bomb. While, Pike, Miller, Bryan, and Octavia escape Indra notices Kane is far too close to bomb and she pushes him away from it to save his life.

In Perverse Instantiation (Part 2), he is seen with the other chipped soldiers climbing the Polis tower. When he reaches the top he is confronted by Octavia who tricks him into thinking she'll take the chip. He seems content with that, however, Octavia throws shock batons into the water electrocuting him and other chipped victims. He soon enters the throne room and finds Bellamy guarding Clarke. He begins to strangle Bellamy but luckily, Clarke is able to terminate the City of Light before he does any more damage. Kane awakens from the City of Light and begins sobbing into his hands. He is soon approached by Abby and they embrace.

 * -|Season Six=

Personality
Kane is a pragmatic individual, cold and willing to do whatever he deems necessary to "save the human race" for the beginning of the series. Rather than seeing himself as overly dedicated or mean, he saw others as lacking what it takes to do what needs to be done. He cared little for the lives of individuals, only for the idea of the human race as a whole.

Following the events of the Culling, however, Kane is filled with regret and remorse over his actions, depicted over the course of the next season and a half. After his failed attempts at leadership, he learns to place trust in his leaders. Marcus eventually ends up being very loyal to those above him. On the Ark after his mother was killed after Diana Sydney's planned explosion in Unity Day. On Earth, he supports and trusts Clarke as his leader.

After Section 17, Marcus becomes very selfless and willing to sacrifice himself. He stands up and begins to offer to leave himself behind on the Ark to allow the remaining humans to make it to Earth in We Are Grounders (Part 2), though Thelonious Jaha is already launching the ship before Marcus can do as such. In Fog of War, when Jaha and Marcus are informed they must kill the other to stop the bloodshed, Marcus never considers hurting Jaha an option. When Thelonious refuses to kill Marcus, Kane slits his wrists with the knife.

Kane often thinks logically rather than emotionally, though he is no longer "cold"; he often shows regret and remorse whenever he is compelled to make a sacrifice for the greater good of his people. What he believes is right is more often than not helpful for more people, such as his suggestion to turn in Finn to the Grounders and establish safety for the remaining Sky People, though he is written off as unfeeling for his objective approach.

Physical Appearance
Kane is a tall man in his forties with wavy dark brown hair and eyes, and tan skin. He appears to have an authoritative presence.

In Season 5, after the 6 years and 7 days jump, his hair is longer to his shoulder and is slicked back.
