Throughout the Series

 * -|Season One=

In Contents Under Pressure, Miller and Drew enter the dropship with Bellamy, holding an unconscious Lincoln. They take him upstairs and restrain him, so Bellamy can attempt to get answers out of him. Meanwhile, Miller goes through the grounder's stuff and they find little vials and a drawing book. Later, he watches Bellamy torture Lincoln in an attempt to get him to confess to which vial is the antidote for the poison on the blade used to stab Finn Collins. They are joined by Raven Reyes who takes a turn out of desperation. At the end of the episode, when Lincoln thanks Octavia for cleaning his wounds, Miller believes he heard him speak but Octavia denies it. He then tells her that Bellamy doesn't want her up there and she leaves.

In Day Trip, Miller approaches Bellamy who is watching over Lincoln and he's been informing some of the Delinquents' parents about their deaths. Afterward, he expresses his desire to kill Lincoln but Bellamy tells him they aren't going to. Miller doesn't hold back, however, messing with the grounder. Lincoln head-butts him after this. Later, when Octavia checks on Lincoln, Miller returns from talking on the radio, and tells her to get out, threatening to beat Lincoln if Octavia doesn't. Octavia obeys him, but after running into a hallucinating Jasper, she concocts a plan. She returns to the top level of the drop ship shortly after with some nuts that she gives to Miller. She claims it's a peace offering and won't go up there again, and he accepts them. After eating the nuts, Miller is shown out front in the camp, talking to himself. This allows Octavia to free Lincoln and help him escape. Later, when he's sobered up, he notices Lincoln missing and warns the others, just in time for Bellamy and Clarke to arrive. He stands in the crowd as he listens to their speech regarding the guns.

In Unity Day, Miller is seen standing around the radio with Raven, Fox, and some of the other Delinquents, as they watch Chancellor Jaha's Unity Day speech. He makes a snide comment about the fact that it's because of the Delinquents that the following Unity Day will be celebrated on the ground, and remarks that someone should shut him up. Raven chimes in, however, and tells him to shut up, to which he brushes off. Later on, during the celebration, he is seen standing by and watching Clarke, Fox and Sterling before Clarke leaves with Finn.

In We Are Grounders (Part 1), Miller announces via walkie talkie that someone is approaching the gates to the camp and calls for all the gunners to prepare. When everyone gathers around camp, Miller is the first to recognize Finn and Clarke, telling the other Delinquents to hold their fire and let them in.

In We Are Grounders (Part 2), Miller is as the front of the pack with Drew, Jasper, and others as Octavia leads them out of camp and into the woods to head to the beach to escape the attacking Grounders. He discusses that once they hit the beach, he plans to go surfing. However, Octavia stops the group and seemingly out of nowhere, a Grounder scout hiding in the trees attacks, throwing a metal object that strikes Drew in the face, instantly killing him. Miller and the other Delinquents retreat to camp, taking Drew's body with them and run to their posts to prepare for the battle.

Once back, Miller gets into his position in the foxhole with Monroe and Octavia. The Grounders approach the camp in no time, though they remain hidden. Bellamy joins them shortly and when he asks about Octavia's whereabouts, Miller informs him that Octavia ran off and makes a comment that he thinks she's a samurai. When the Grounders finally attack, Monroe flees in fear. Miller calls for her but one pounces on Bellamy. Miller calls out his name but before he could help, he is hit in the shoulder with a spear, and Bellamy is nearly killed until Octavia shows up just in time to save them. Bellamy orders that Miller return to camp, while he attends a wounded Octavia.

Back at camp, the Delinquents are doing everything in their power to fight back. However, most have returned to the drop ship. Miller enters, holding onto his wounded shoulder and informs Clarke that the Grounders are making it inside, and states he's going to shut the drop ship door. Clarke tells him not to though because they're still waiting for Finn and Bellamy. They go outside and Miller attempts to shoot at grounders that have made it past the wall, as Clarke attempts to get Finn and Bellamy. It doesn't last long, however, because the grounders kill multiple Delinquents and Miller rushes to Clarke and tells her that she can't save everyone and that they need to go inside. Finn gives her a nod from where he is, and eventually Clarke relents. Miller and Clarke return to the drop ship and shuts the main door.

However, Anya arrives just in time and manages to jump onto the drop ship before it closes. She attempts to attack the Delinquents before Miller strikes her in the head from behind, allowing him and some other Delinquents to kick her while she's down. Miller tries to finish her off with his knife, claiming that she deserves to die, but Clarke stops him and tells the Delinquents that they are not grounders. Jasper finishes just in time, and sets off the explosives, obliterating all the attacking grounders and any other bodies left behind.

When the sun rises, the Delinquents exit the dropship and take in what's left of the camp. Charred corpses surround them and they look upon the wreckage in despair. Gas grenades are suddenly tossed onto the campsite, and all of the surviving Delinquents are taken back to their base in Mount Weather.


 * -|Season Two=

In Inclement Weather, Miller makes his first appearance, being released after being in surgery for the injury sustained from battle. Maya gives him a bottle of pills, and Clarke welcomes him back to which he gives her a polite nod. He makes a comment afterward, though, alluding to her behavior since getting out of her room, to which Clarke gawks at Maya. Miller is later seen reading a book in his bottom bunk as Clarke talks to Jasper about her suspicion with Mount Weather. Jasper remarks her behavior as "crazy" and asks her what they might do to her if she keeps up her act, and Miller chimes in, deadpanning that she would be kicked out. Afterward, Clarke slumps in her seat in the mess hall, as she watches over her friends enjoying their stay, including Miller who beats another at arm wrestling. At the end of the episode, Miller's father is introduced and asks Bellamy to find his son, which marks the first time Miller is acknowledged by full name in the series, and Bellamy promises to do so.

In Fog of War, Miller is in the dormitory with the rest of the Delinquents, giving Jasper their attention. He is trying to convince everyone to volunteer for the blood transfusion for the Mountain Men, but Miller refuses, and Harper, Monty, and the others follow. Later, they relent, albeit off screen, and Miller is shown to be one of them. Him, along with Jasper, Monty, and Harper gather and Jasper states that they need to buy Clarke some time to come rescue them.

In Long Into an Abyss, Miller and the others are unhappy since the blood transfusion and Jasper states that them cooperating is good because it buys them some time. Miller, however, is unimpressed and states that if they're going to die, it might as well be by trying to escape to which the others agree. Jasper continues to try to maintain hope that Clarke will save them, however, but Monty tells him that Clarke may not have even escaped and she may be dead. Harper insists they try to escape, but Jasper says instead, they should find the truth.

Later on, Miller is standing watch as Monty attempts to get Dante's office door open. He seems anxious, though, and Jasper tells him to relax as Maya is helping them to which Miller doesn't seem convinced of. When Monty finally gets the door open, the group make their way inside. Miller attempts to get the drawers open as Monty attempts to hack into the computer. After some time, Miller finds something in one of the drawers and at the same time, Monty finds surveillance photos of Camp Jaha. This surprises the others as they were told there were no survivors.

Later, Miller and Monty are in the dormitory, looking at the papers Miller found. He states that if Alpha Station is on the ground, other stations may be as well. At this, Monty mentions that Miller was from Alpha Station and Miller informs him that his father was chief guard. He then makes a sarcastic comment that his father loved having a thief for a kid. Monty assures him that he's a great thief, though, to which Miller softly chuckles. Jasper enters the dormitories after that, asking where Harper is, but neither have seen her.

In Remember Me, Miller is playing a card game with Monty when Jasper and Maya arrive and join them. They gather to discuss the possible whereabouts of Harper, but Miller makes snide comments at Maya, and Jasper rushes to defend her and inform him that she's on their side, but Miller isn't convinced. During this, Monty inspects the base's map and informs them that they need to get to the wires that run into the antenna on the ground so that they can broadcast a message to the Ark survivors, and then tells them what they need.

Later, they get to the art warehouse and Miller has another dispute with Maya and Jasper when she tells him that the Mountain Men will hear if he pounds the wall with the hammer. She counts down to five and an alarm echoes through the base. This enables him to bash a whole in the wall, and Monty begins work. He attempts to get their message to send, but he's having issues unjamming the frequency. Maya returns then to warn them that a guard is coming, and they flee. Later, Jasper and Maya meet up with Miller at the dormitories and ask where Monty is, but Miller claims that he thought he was with them. They realize what's happened then, and Miller appears to be upset by this news.

In Coup de Grâce, Miller is seen standing in the dormitories with the other delinquents as Jasper and Monty alert them that they are leaving. They begin to pack up when an alarm sounds suddenly blares and the doors slam shut, locking them inside.

In Rubicon, Miller are awaiting news after being locked up for hours. Jasper tells them that Bellamy is there, but the others are skeptical. Suddenly, Dr. Lorelei Tsing enters the room with guards and take one of the kids away. He glares at her as she tells them that they are no longer leaving as Dante is no longer in charge. He attempts to stick with the others when they return for another, but the guards get physical and drag her off anyway.

Later, he stands alongside the other delinquents as they link arms, but again, they break them apart and begin to drag Monty away. During this, they attempt to fight back against the guards. They don't fair too well, however, and are beaten down. They trade Monty for Jasper and walk off. However, a radiation leak is exposed, thanks to Bellamy. This causes the Mount Weather guards to fall to the ground, weak and in pain. The delinquents are able to be free as a result, and take the guards' guns as they die. Dr. Tsing attempts to escape via the elevator, but Jasper stops its doors before they close and he, Harper, Monty and Miller stand in the doorway and ignore her cry as they watch her die.

In Resurrection, the delinquents have moved to the mess hall, and Miller and some of the others begin to barricade the main doors. Things are slow for a bit when they finish, though, awaiting an attack. The delinquents get into their positions and prepare for a fight. Miller is armed with a cleaver, and he tells Harper to be careful as she has a gun because she could hit one of them. After this, the guards bust the doors open and then throw gas grenades into the hall. When the guards take down the barricade a few moments later, they walk in and find the delinquents on the ground, presumably unconscious. It is revealed the grenades were tossed into buckets of water, and they are faking it. Jasper initiates the attack, and the delinquents jump up from their positions and fight back. Miller is seen attacking a guardsman with a post. After they retreat, Fox screams for Jasper as she is dragged away by a few guards. Jasper attempts to run after her, but Miller restrains him and calms him down, telling him that she'll be okay, though he is still visible upset.

Later, Miller informs Jasper that they are going to attack harder next time and states that they need more than a few guns and a few buckets of water to fight back and wait for Bellamy to rescue them. After Maya is set up to be killed if the delinquents don't surrender, Miller surrounds her with Jasper and Monty. Monty states he's going to fix the entrance to the trash shoot and Jasper tells Miller to help. He calls for Harper to join them and then follows. He watches as Monty tries to fix it, but when Monty gets impatient, he asks Miller to help him force it open. It is then when a force is heard on the other side and they all jump back, only to find it's Bellamy. He, Maya and Jasper go down the shoot and Maya is rescued. It is revealed towards the end of the episode that the delinquents escaped through the trash shoot. Miller comments that they're all just sitting ducks walking around in a group and Bellamy tells him that they're going to split up. When he makes a comment that Maya can't help them anymore, he asks who's going to help them now. Bellamy states, "They are." He leads them to acquaintances of Maya's family that don't agree with Cage. Maya's father motions for them to come, and tells them that they are going to be divided along the way. Miller follows immediately.

In Blood Must Have Blood (Part 1), Miller is seen in captivity with Jasper, Maya and Fox, their hands restrained in handcuffs as they are forced to follow one of the Mount Weather guards, Paul. Vincent, however, steps in the way and refuses to let them take Maya despite Maya's pleas. Miller looks over at Maya with remorse when Paul pulls out his gun to shoot Vincent, but Bellamy shoots Paul from inside the ventilation, killing him, and the other guard that was following behind rushes over to get Bellamy when Miller kicks the guard in the back of the leg, knocking him down onto his knees and then wraps his arms around the guard, pulling the handcuffs against his throat, strangling him, before smashing his head against the concrete walls. When Bellamy exits, he asks Miller if he's okay to which he replies, 'Better than him,' gesturing towards the dead guard on the floor as Jasper frees his hands. Bellamy then tells Vincent to get them to the harvest chamber and him, Miller, and Fox go as Jasper and Maya join Bellamy to find Monty. It's later revealed the harvest chamber has been cleared, the grounders freed as part of the deal Mount Weather made with Lexa and the delinquents captured.

In Blood Must Have Blood (Part 2), Miller is handcuffed to the wall when the Mount Weather guards bring in more Camp Jaha residents, his dad included. When he's revealed, Miller is shocked to see him. His dad is relieved to finally be reunited with him, but he is struck in the back of the head when he tries to run to him. This enrages Miller, who shouts at the guards from where he's restrained, tugging at the handcuffs above him, trying to be freed. Later, after the Mount Weather civilians are killed, the Millers are freed and are finally reunited. They smile as they take in the moment and then embrace. At the end of the episode, when the Sky People arrive home at Camp Jaha, Miller is seen walking side-by-side with David, his father's jacket around him.


 * -|Season Three=

In Wanheda (Part 1), Miller walks up to Bellamy while he is choosing people to come along for his mapping mission. Bellamy tosses Miller a gun and allows him to come. While driving, Miller joins in the sing-a-long of Add It Up, but the fun is cut short when the group receives a signal from Farm Station, which Miller's boyfriend is from. The gang realizes that Farm Station is in Ice Nation territory, but Miller insists they go. Miller and the others reach the border of Ice Nation in Sector 8. He steps outside with the others to greet the three Ice Nation warriors that arrive. Jasper grabs the beacon off of one of the warriors, laughs about it, and in turn, the warrior slits Jasper's throat. Miller, along with the rest of his friends, shoot and kill the three warriors. Miller manages to make it back to Arkadia with the others unharmed.

In Watch the Thrones, Miller is seen with his boyfriend, Bryan, attending the memorial for those from Farm Station that were killed at Mount Weather. He comforts Bryan as he grieves, and even encourages him to go forth and speak for one of the deceased.

In Hakeldama, Miller approaches the cell holding the Grounders, coming face to face with Lincoln. He tells the other guards to be careful because "this one doesn't like to be chained up". He then says to Lincoln that Octavia is not here to free him this time. But it is all an act. Miller opens an opening in the door and slips through a small bottle. Checking to see if the other guard is looking, Miller whispers to Lincoln that it is from Abby for Danae, a sick Grounder in the cell. He then informs Lincoln that Octavia got out with Clarke.

In Bitter Harvest, Miller brings Octavia a horse. He then questions her about what she plans to do because asking the Grounders to leave doesn't seem realistic. He adds that if the Grounders don't leave, they will be leading their people into an ambush. He suggests she talk to Bellamy but then realizes that they don't have another choice because if they don't stop the attack on the village, it'll be war and more dead friends.

Back in Arkadia, Miller is greeted by Bryan who was worried about his whereabouts. He lies to him, telling him that he lost a horse while he actually gave it to Octavia. He continues by telling how he wished Bryan didn't have to go on the mission to wipe out the village. Before leaving, Miller tells Bryan to be careful and they hug. As he watches Rover leave, Miller nods to Kane.

In Terms and Conditions, he is seen spying on Pike's meeting along with Kane and Harper. He also worries about Octavia who hasn't report back to them for a while.

Later that day, Bryan enters their quarters just as Miller is getting reading to leave for work. They speak of not seeing each other often due to having opposite shifts, with Bryan working days and Miller working nights. The conversation switches to Pike's politics, which is a sensitive topic since Bryan stands behind their Chancellor while Miller supports Kane. Bryan helps Miller put his jacket on and they kiss goodbye before Miller leaves for work.

Because Bryan bugged Miller's jacket, Monty overhears a conversation between him and Harper, proving that they are both working with Kane against Pike. At the end of the day, Miller, Bryan, and Harper sit around a camp fire and he and Harper exchange glances. Bellamy and Monty decide to not give up his name when questioned if they found other traitors.


 * -|Season Four=

In Heavy Lies the Crown, In Arkadia, Clarke, Bellamy, Raven, and Monty try to find a way to ride out the radiation and are debating whether the masses should be told. Suddenly, Monty realizes that they can survive inside Alpha Station as long as they patch up the ship. The next day, Bellamy explains the plan to Miller and Bryan and tells them they need to go to Farm Station to fetch a hydro generator. They arrive in the Ice Nation and find that Farm Station is inhabited by members of the Ice Nation. Suddenly, Ice Nation members surround them and take them to the station to meet the chief. Bellamy tells them they're just they're for the hydro generator at the request of King Roan. The Ice Nation members agree to let them take the machine. The crew goes to get the machine, but notice many people, including Riley, serving as slaves. The Ice Nation members tell them the deal was the take only the machine and the rest will remain theirs. Bellamy, Monty, Harper, Miller, and Bryan are debating whether they should save the slaves or take the hydro generator. Bryan and Harper want to free to slaves while Miller and Monty want to take the machine. The final decision is Bellamy's and he decides to use the machine to free the slaves. They take the machine, rigging it as a bomb and free the slaves. Many of Azgeda die in the explosion and their the chief is beaten to death by the slaves. They arrive back in Arkadia to be met with by Clarke and Raven. Bellamy confesses they didn't get the machine and rather used it to save the slaves. This reduces the number of people who can survive inside of Alpha Station to only one hundred.

In The Four Horsemen, he and his father are patrolling the front gates of Arkadia when Murphy approaches to them. They allow him to go through.

In A Lie Guarded, Miller leaves Arkadia with Jackson, Abby, Murphy, Emori, Luna, Raven, and a couple Guards. Once they arrive on Becca's Island, they approach a marker shaped like the Washington monument, and Emori pauses. She remembers that A.L.I.E. had a rule about not crossing a line there, but Murphy doesn't care. They all decide to walk past the line, when suddenly a drone shows up and shoots one of the Guards in the head. It begins to chase the rest of them, shooting at every moving target. They all decide to split up to search for Luna. Emori tells Murphy that there are more dangerous things on the island other than the drones. She keeps telling Murphy they need to find a place to hide away, but Abby interrupts them saying they need to keep moving. Raven attempt to run for the damaged drone. However, she starts getting shot at by another drone and needs a new plan. Suddenly we see that Jackson is shot and pinned down by the active drone. Even though he's accompanied by Nate, they're out of ammunition and need help. This is where Luna decides to help by acting as a decoy for the drone while Raven shoots at it. Luna runs into the forest after picking up the damaged drone. Raven begins to access the drone's system in order to alter its programming. We then see Abby run out and try to be a decoy as the active drone approaches her. Just as the drone attempts to shoot her, it deactivates and falls to the ground. Raven saved them by finding a way to hack the drones' systems.

In God Complex, Miller, Clarke, Abby, Jackson, Emori, Murphy, Raven, Roan, and Luna begin testing on an unnamed Grounder that Emori marked as "Baylis". It starts off well, he survives the amount of radiation of the black rain. However, when they increase the radiation levels, he dies a violent death, coughing up black blood. The test is deemed a failure. Emori's lie about the test subject's identity surfaces, resulting in her and Murphy getting locked up. In the lab, they are preparing Emori for the radiation chamber. Abby doesn't manage to inject her, so Clarke takes over. After contemplating, she injects herself instead. Her mother is not happy with this. After two hours have passed, Clarke's preparing to be tested. Abby doesn't want to let her go in. She explains that she saw Clarke with radiation poisoning her vision. Abby then smashes the radiation chamber until it's unusable.

In DNR, Nathan and Jackson enter The Lab to get Emori and Murphy back to Arkadia, leaving Raven alone.

The group come across a small lake and Murphy jumps in to swim, Nathan shouts him that the water may be unsafe and he didn't heal his wounds, however the water seems to be safe too. Later, sitting around the campfire he and Eric relaxes and talks about their new status as aliens, while they are observing a bug that they caught up in a jar.

As an eclipse approaches, the group notices that a bug they had captured in a jar is becoming extremely violent. Suddenly, a huge swarm of bugs approaches them at high speed. They run to seek shelter while using fire flares to scare off the bugs. Soon, they reach an electric tower with a radiation fence which kills the bugs. Shaw accidentally runs through the electric barrier and gets burned by the radiation. Clarke notices that they are radiation-type shockers and she can go through them because she has nightblood. She goes through the barriers and disables the tower temporarily to let the rest of the group get inside.

The group continues to explore while waiting for Raven to contact them. They explore more houses and find people in photographs standing by an American flag. Murphy finds a music player and turns it on.

While Miller and Jackson talking to each other sitting on the stairs they get interrupted by Murphy yelling at something. Miller then shouts that someone stole their transport ship and it's now flying away. A couple moments later, Emori starts attacking Murphy out of nowhere. The group quickly comes to save him and notices that Emori turned violent during the eclipse in a manner similar to what's depicted in the "Red Sun Rising" book.
