Octavia Blakè is a character in The 100. She débuts in the first episode of the first season of The 100. She is portrayed by starring member Marie Avgeropoulos and guest starring member Olivia Steele-Falconer.
Aurora Blake, Bellamy's mother, was forced to keep her second pregnancy a secret because of the one child law on the Ark. A young Bellamy watched his mother give birth to his sister and even helped keep her quiet after the birth. After the child was born, Aurora told Bellamy to name her. He had learned about the Roman emperor, Augustus, and named his sister after the emperor's sister, Octavia. Aurora told Bellamy that Octavia was his responsibility. He told her he loves her very much and promises to keep her safe, no matter what may happen. Because Octavia was an illegal second child, she had to be kept hidden in their room, never venturing out. Bellamy would tell her stories and play with her, telling her about the Ark. Their mother would also read them mythology, which Octavia loved. Octavia would also help Aurora, who was a seamstress on the Ark. In order to find out about the surprise inspections ahead of time, Aurora was sleeping with an Ark Guard and she was also trying to get Bellamy a position on the guard. During these inspections, Octavia was forced to hide under the floorboards and wait quietly until they were done. Bellamy told her to tell herself, "I am not afraid."
Octavia was finally exposed a year before they were sent to earth. Bellamy had become an Ark Guard Cadet and was able to get duty during the Unity Day masquerade party. He sneaks Octavia out of their room so she could attend and promises her that he'll keep her safe and deliver her home before their mother even knows they're gone. The party is disrupted by a solar flare alert, requiring everyone to show ID. Since Octavia didn't have any ID, they knew they would be caught. Bellamy tells her to go straight back to their room and hide but Octavia admits to him that she doesn't know how to get back. Commander Shumway notices that Bellamy has his shock baton out and starts to question them. Bellamy begs Commander Shumway to let her go, but he refuses stating Bellamy is not a guardsman yet. Octavia tries to run but is easily captured. Bellamy suddenly loses his sister, his mother, and his chance to be an Ark guard and becomes a janitor.
Sent to the Earth
Over the next year, Bellamy is unable to see Octavia in Lockup. He is then approached by Commander Shumway who tells Bellamy that 100 prisoners are being sent to the ground, among them his sister. He offer Bellamy the chance to go to Earth and protect Octavia but only if he shoots and kills the Chancellor. Bellamy accepts the deal and stows away on the drop ship.
Octavia is sent down to Earth with the other delinquents. When the spaceship lands she is reunited with her brother, Bellamy. Because she is the only one with a sibling, the delinquents realize that she is the illegal second child who used to hide under the floor. She doesn't take the comments well so Bellamy tells her she should give them something else to remember her by: she should be remembered as the first person to walk back on Earth. Later, Octavia goes to Mount Weather with Clarke, Finn, Monty and Jasper. When asked about why she was arrested she responds, "for being born." On their way to Mount Weather she stops to swim in a river where she is attacked by a sea creature. Jasper helps save her and they stop for the night. The next morning, Octavia watches Jasper swinging on a vine to cross the river to Mount Weather before he is pierced in the chest by a spear.
At the beginning of the episode, Octavia looks horrified after witnessing Jasper being speared and manages to escape back to camp with the rest of the group. Bellamy is worried about her and insists on treating her wound from the river serpent. She winces with pain while he is cleaning it, but she bares through it. When Clarke says they need to go after Jasper, she quickly volunteers to do so but is shot down by Clarke (who thinks her leg will slow them down) and Bellamy (who doesn't want her to get hurt again). Atom is left to watch over her and Octavia quickly begins taunting him, saying how he can't not follow orders. Atom eventually gets fed up and locks her in the drop ship with Monty, who is trying to find a way to communicate with the Ark. Octavia encourages Monty saying that Jasper would understand why he didn't go after him. After Atom lets her back out of the drop ship, she wanders off following a butterfly and discovers a field full of them. Atom follows after her and Octavia kisses him. The two are seen kissing again later, only with Bellamy catching them and tying Atom up on a tree.
Octavia remains at the camp and watches over Jasper as he recovers from his wounds. She gets in a fight with Bellamy when she finds out that he has scared Atom off from being with her any more. When Murphy tries to silence Jasper by killing him, she and Monty block him from getting to Jasper. When she hears of Atom's death, she confronts her brother and yells at him for his behavior.
Octavia tries to take Jasper out into the forest as he had fully recovered from his wounds but John Mbege grabs her from behind, frightening Jasper who trips and inadvertently discovers Wells' amputated fingers and a knife with the initials "J.M." They take these to Bellamy and Clarke, with the latter confronting Murphy about it. Charlotte, however, is revealed to be the true murderer and Murphy decides she needs to be punished like he was (hanged). Jasper tries to stop him but gets punched and Octavia shows concern for him. Later, when Jasper attempts to put the finishing touches on setting up the communication between the Ark and the drop ship, it fails and wipes out all the wristbands. Jasper laments that he is cursed. Octavia tells him he is not cursed but brave and kisses him.
Octavia watches the Mir-3 escape pod crash to earth with the other delinquents and Bellamy tells her that they will search for it in the morning. Bellamy instead goes out searching for it in the night and Octavia follows him, eventually confronting him about his lies. Bellamy reveals that the reason he wants to find the ship is because he shot Chancellor Jaha in order to get on the drop ship with Octavia. Octavia is furious with him for this and storms off. While heading back to camp she trips down a hill and is knocked unconscious. Later, when she awakens, she discovers a Grounder watching her.
Octavia awakens in a cave belonging to a Grounder, the same Grounder she saw earlier. He enters the room she's being held in and seals her leg wound shut. After the Grounder exits the room, Octavia proceeds to crawl out of the cave through a small opening and manages to run away, heading back to camp. She is quickly recaptured by the same Grounder, however, and is held captive while she watches Roma die at the hands of the Grounder traps and realizes the Grounder had saved her life. As he carries Octavia back to his cave, she pleads with him to save her brother. When they get back to the cave, he chains her up and leaves her again. Octavia "freaks out" about being chained up and when the Grounder returns, she hits him over the head, knocking him out. As she's scrambling to free herself, Bellamy, Jasper, Monroe, and Finn discover her location and help free her. Bellamy wants to kill the Grounder, but Octavia tells him that the Grounder had saved her life. Finn reaches for the Grounder's horn that had saved them from the acid fog but the Grounder awakens and stabs Finn. He pins Bellamy down and Octavia begs him not to kill Bellamy right before Jasper knocks him out. Bellamy then hugs Octavia and gets the others to carry Finn back to camp. Once back at camp, Octavia tries to leave again but Bellamy prevents her and they get into another massive fight.
Octavia is seen assisting Clarke with Finn's stabbing when Bellamy, Miller, and Drew drag the Grounder that saved Octavia into the drop ship. She follows them up to the third level where they tie up the Grounder but is told to leave. Octavia eventually follows Clarke back into the room where the Grounder is being beaten and interrogated. This upsets her because the Grounder had saved their lives. Finn's condition worsens when it's discovered the blade was poisoned. As Bellamy, Clarke, and Raven grow increasingly more brutal in the torture of the Grounder, Octavia puts a stop to it by slicing herself with the knife that the Grounder used on Finn, forcing the Grounder to reveal the correct antidote in order to save Octavia's life. At the end of the episode, Octavia takes over for Clarke and tends to the Grounder's wounds. Once Clarke leaves, the Grounder thanks Octavia. Miller asks if he heard the Grounder speak and Octavia lies to him as she continues tending to the Grounder's wounds.
Octavia is waiting to see the Grounder and Bellamy tells her she doesn't get to see him. Bellamy then leaves on a mission with Clarke. When Connor tells Miller that he needs to speak with Roma's parents, Octavia enters the room where the grounder is locked up and closes the hatch. Octavia mentions how Bellamy can be a dick sometimes and he smiles in agreement. She introduces herself and talks to him and he reveals his name to be Lincoln, asking her to remember him when he is dead. Miller returns and threatens to beat the grounder if Octavia doesn't leave so she does. Later on, Jasper runs up to her, hallucinating on jobi nuts. Octavia gets the idea to give jobi nuts to the delinquents, including Miller. Once everyone else is incapacitated, Octavia steals some clothes and sneaks back up to see Lincoln. She unties him and helps him get dressed. As he's about to leave, he turns around and kisses her passionately before escaping from the the drop ship. Soon after, Bellamy returns from his trip with Clarke and asks Octavia about Lincoln escaping. She replies by lying, saying she had nothing to do with it.
Octavia sneaks away from the Unity Day Celebration with only Finn noticing her leaving. After following some white flowers, Octavia tries to sneak up on Lincoln in his cave, at first looking like she's going to kill him, but he has actually been training her to be a "warrior." It is then revealed that the two are now lovers. Finn shows up while they are saying goodbye and strikes up a deal for their leaders to meet to discuss peace. Lincoln brings his leader (Anya) and Finn brings Clarke but unknowingly to Finn, Lincoln, and Octavia, both leaders brought back-up. When things don't go as planned, Lincoln is hit by an arrow (calling it a "scratch") while trying to protect Octavia. Lincoln tells them to get back to their drop ship and takes off the other way. Back at camp, Octavia blames Jasper for ruining everything, and she walks away, angry.
Octavia spots a white flower outside camp walls right before a delinquent starts firing into the forest at some movement. Octavia is worried that it might be Lincoln so she goes outside the walls to find out who it was. It turns out that a badly beaten and tortured Murphy has returned to their camp after having been banished by Clarke and Bellamy. It is quickly discovered that Murphy was tortured by the Grounders before "escaping" and has brought a type of hemorrhagic fever back into their camp as the delinquents start getting very sick. Bellamy is worried about Octavia because she was the first one to find Murphy so he goes to check on her and catches her reading Lincoln's journal. He brings her to Clarke and Clarke tells Bellamy that she needs to quarantine her. Once Bellamy leaves, Clarke tells Octavia that she needs to talk to Lincoln to get the cure. When Octavia arrives at Lincoln's cave, he is happy to see that she is unaffected, calling her strong. He tells her that the grounders will attack at dawn and asks her to come with him as he is leaving. His people think he's a traitor because he loves Octavia. Octavia decides to go with him, but first she needs to warn her people of the impending attack. Back at the drop ship, when Bellamy falls ill, Octavia takes care of him, making the same promise that he made her when she was born. She spends the night tending to the sick as she is immune. At first light, Octavia sneaks back to Lincoln and tells him that she can't go with him because she's decided to stay and help her people.
Octavia is working in the Smokehouse with Murphy when Del brings in more wood for the fire. Octavia warns Del that they have too much wood but he decides to ignore her warning. As a result the Smokehouse ends up burning down. Later, Octavia joins the search party for Finn, Clarke, and Myles.
Octavia tells Bellamy that he is scaring people as he yells at one of the Delinquents for dozing off on their watch. When Jasper is taken hostage by Murphy, she challenges Bellamy to do something about it, which he was already doing when he sent Raven under the drop ship to figure out a way to open the door. After Bellamy trades places with Jasper, Octavia stays on the radio with Bellamy the whole time he and Murphy are locked in the drop ship together. After Bellamy is hanged by Murphy, she comforts him and encourages him to breathe. She witnesses Murphy's escape and Bellamy's motivational speech. When Clarke and Finn return after Lincoln helped them escape from the Grounders and the Reapers, Finn hands her Lincoln's sword, shaking his head to show that he didn't think Lincoln had escaped the Reapers.
Octavia fights with the other Delinquents in the war with the Grounders, despite her brother not want wanting her to. She later saves Bellamy's life after a Grounder attacks him. She is hit with an arrow and Bellamy is unable to get her back to the drop ship. Lincoln appears after he and Finn diverted the Reapers to the Grounders to help the Delinquents. Octavia is glad to see that he is still alive and Lincoln tells Bellamy that he can save her if they leave right away. Bellamy gives Lincoln permission to save Octavia and then they say their last goodbyes. Octavia is deeply saddened when she has to leave her brother behind.
Octavia practices Lincoln's native language as Lincoln gathers ingredients from a river to treat the arrow wound in her leg. Octavia asks why she needs to learn the language and Lincoln explains to Octavia that only the Grounder warriors speak English and in order to blend in she needs to speak his native language. Octavia tells Lincoln to stop stalling and pull out the arrow, which he immediately does. He then cauterizes the wound and tastes the arrow tip, spitting when he realizes it was poisoned. Octavia tries to convince Lincoln not to go back to his village because if he does, he'll die the death of a thousand cuts and then be fed to the bugs. Lincoln comes up with a plan to use the beetles in the river as an antidote and leaves to collect the bugs. While Lincoln is away, Octavia begins screaming. When Lincoln returns, Octavia tells hims she saw a man who was more monster than man. Lincoln thinks she is hallucinating from the poison and they're running out of time. He picks her up and carries her away from the river. As they walk through the forest, Lincoln asks her to repeat the phrase he told her earlier in his native language. Octavia does so but grows fearful when she can't smell anything. Later, Octavia learns that Lincoln lied to her and took her to his village instead of taking her to the ocean. He promises to come back and leaves her alone near the statue of Abraham Lincoln.
Octavia awakes near the same statue. She sees a man a few feet away from her. He approaches her and hands her a concoction. When she asks about Lincoln, he says she needs to drink it. She asks the name of the man (Nyko), and is confused when he tells her she should run. Nyko tells her that Lincoln is paying for what he did (for helping her) while their clan is weak. She then says they have to do something but he says he did something by helping her and that she should run. After that she hits him and takes him as a hostage to Lincoln's village. She demands of the leader (Indra) an exchange for their healer, Nyko: she wants Lincoln. She tells the leader to bring Lincoln to the place she last saw him then threatens to kill her hostage if anyone else comes along. She says they have until dark. When dusk arrives, Octavia successfully swaps Nyko for Lincoln. As Lincoln is returned to her, they are ambushed by Reapers and both Lincoln and Nyko are taken away.
Octavia urges Indra to let her help search for Lincoln and Nyko. When Indra orders her death, Octavia runs from the Grounders and hides. Later, Octavia continues to follow Indra and her group as they search for Nyko and Lincoln. When Indra reveals that Octavia will be the bait for the Reapers she announces that she is not afraid. Octavia helps Indra and the other Grounders fight off the Reapers and at one point,Artigas saves her life. When Indra is defenseless, Octavia saves her by killing the Reaper who would have killed Indra. Once the Reapers are taken care of, Octavia discovers from Nyko that Lincoln is not among the freed Grounders. When she doesn't find him she screams out in anguish.</ref>"Reapercussions"</ref>
Octavia blows Lincoln's Acid Fog horn in order to call off a Grounder attack on some of the Delinquents. She is reunited with her brother and helps treat Monroe's arrow wound. Bellamy offers his sympathy when he learns that Lincoln didn't make it to safety. Octavia goes with her brother, Monroe, and Mel back to Camp Jaha while Finn and Murphy continue looking for Clarke and the rest of the missing delinquents.
Octavia witnesses Clarke hugging Bellamy when they make it back to camp, remarking she never thought she would see that. Clarke gives Octavia a hug, too. Octavia begins to lead the way to the Lincoln's village to bring back Murphy and Finn. Once night comes, they make camp in the woods and sleep. Octavia makes Clarke and Bellamy include Lincoln in their mission to rescue the remaining Delinquents from Mount Weather. She then insists they keep moving. Once at the Abraham Lincoln Memorial statue near the Grounder village, Bellamy comforts Octavia as she cries in his arms because she couldn't save Lincoln. They hear gunshots going off and the trio show up in time to see Finn massacring the grounders. Octavia immediately rushes over to Artigas' lifeless body. She is saddened by his death as he had once saved her life from Reapers.
Octavia and Bellamy go along on the mission to take out Mount Weather's radio tower. They sneak off from the group in order to search on their own for Lincoln. Their absence is soon noticed and some Ark guards are sent after them. Acid Fog descends upon everyone and Octavia follows the fleeing critters to a sealed door. They get the door open and make it into a long-forgotten parking garage, rescuing two of the three the Ark guards who had followed them (one was swallowed up by the fog). They split up from the guards with Sgt. Scott giving Bellamy a gun. They soon hear the guards screaming and run to them only to see Reapers devouring them. Bellamy kills the two Reapers and then they spot another one kneeling over Sgt. Scott. Octavia recognizes it's Lincoln and calls out to him. He turns and starts to attack her and she shoots him in the leg. She and Bellamy escape and plan a way to lure Lincoln back out so they can capture him. Octavia acts as bait and Bellamy uses the Ark guard's stun stick to knock Lincoln out. He tells Octavia that they will take Lincoln home.
Octavia is sitting in the drop ship room where Lincoln is once again chained to the walls while Clarke and Bellamy are discussing what the Mountain Men are doing to the Sky People and the Grounders. Lincoln manages to break free and attacks them. Octavia hits Lincoln over the head, knocking him unconscious. They get him chained back up and Octavia tries to give him some water but Lincoln thrashes at her, upsetting her. She leaves the drop ship to get some more water and spots a white flower in a tree, the same signal Lincoln had used with her in the past. Nyko appears and tells Octavia that the Commander will arrive soon and if they don't leave they will all die. When Nyko hears screams coming from the drop ship, he asks what it is and Octavia tells him it's Lincoln. Nyko immediately understands what she means: that Lincoln has become a Reaper. When Nyko comes in to see Lincoln, he spots Finn and wants to kill him for the massacre he caused earlier in Tondc. When Bellamy attempts to shoot Nyko, Octavia tries to stop him but Clarke shocks Nyko with an Ark guard's stun stick, knocking him out. Later, when Abby is unable to resuscitate Lincoln, Octavia refuses to believe it and continues CPR until she finally gives up, thinking Lincoln is dead for good. Moments later, Abby comes up with the idea to use the shock-baton as a defibrillator and brings Lincoln back to life. Octavia kisses him, happy to see that he is alive.
Octavia is with Lincoln in Camp Jaha's medical facility where he is recovering from being a Reaper. She's trying to keep him comfortable by fluffing his pillows. Clarke visits with Abigail Griffin and they ask 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 dead Finn had massacred were Lincoln's friends, too. Later, Marcus Kane and Abby are talking with Lincoln and Octavia 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's 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.
Octavia wants to talk to Lincoln but Lincoln doesn't want to talk about being a Reaper she tells him he's not that monster and they kiss. Later, Octavia is seen with Lincoln in Tondc, standing with the others while Finn´s body along with the other 18 Grounder bodies are lit on fire. Soon after that, when Gustus is poisoned at the peace dinner and Raven is blamed for it, Octavia asks Lincoln to talk to Indra to intervene on their behalf so they won't kill Raven. Indra tells Lincoln that he is one of the Sky People now in disdain. Later, Lincoln decides to help Bellamy get through the tunnels to Mount Weather in order to face what he had done as a Reaper. Octavia wants to join but Lincoln tells her that she needs to stay behind to make sure the Grounder-Sky People alliance doesn't fail since she has knowledge of both worlds now.
Octavia stands Camp Jaha guard as Grounders enter the camp for a meeting between Sky People and Grounders. She attempts to get Indra to let her train with the grounders, but Indra refuses. Later, as the Grounders are about to leave Camp Jaha, Octavia picks a fight with one of the Grounders so she can get trained with them like she wanted to. The Grounder, Fio, beats her up pretty severely, but Octavia continues to stand up again and again until Indra calls it off. As Octavia is recuperating from the fight, Indra appears and tells her that she fought like a child but Indra is willing to train her and take her on as her Second. Octavia agrees. After Indra and the grounders bring back food for the people of Camp Jaha, Kane acknowledges that it was Octavia who brought the Grounders and the Sky People together. Fio, the man whom she had sparred with earlier, brings her a plate of food. Kane asks her to "look out for [her] people," to which Octavia ambiguously replies that she is.
Octavia kills one of the Mount Weather guards and is about to kill the other one when Clarke arrives and stops her, telling her they are going to need him to get answers. Later, she tells Clarke that she is worried about Lincoln because he should be back from the mines by now. Clarke calms her by telling her that he and Bellamy are going to be all right. Soon after that, Octavia, along with Clarke and Indra, get the prisoner out of the airlock so he can deliver to Mount Weather a message from Clarke. After he takes off, Octavia asks Clarke how this is going to help Bellamy and Clarke tells her she wants Mount Weather to look at the army outside so they won't discover Bellamy inside. Octavia then walks away with Clarke and Indra.
Octavia is seen in Tondc with Indra telling her that she is worried about Lincoln not being back yet. Indra answers that Lincoln is no longer her concern and that she can worry about him when the battle is finished. Octavia is then put on watch with another Grounder, Atohl of the Ice Nation. When they hear a noise, Atohl goes to investigate and soon after Octavia hears him scream. She follows after him and finds Lincoln standing over Atohl, tying him up to take back to Mount Weather in exchange for more of the Reaper drug. She tells Lincoln to get off him and to come with her. Refusing to answer Octavia, Lincoln receives a punch in the face and Octavia quotes something he had said to her a while ago: "Ge smak daun, gyon op nodotaim." (Get knocked down, get back up!) and says, "Grounders don't give up. We fight," with the ultimatum that he can either get back up and fight what the Mountain Men did to him or he can "crawl away and die alone like a coward." Lincoln goes with her and at the end of the episode they are seen standing in front of Tondc after the missile hit, staring at the destruction in shock.
After they're pinned down from rescuing people by a sniper, Lincoln decides to go after the shooter. He tells Octavia that she needs to remain with Nyko and help him since Indra was shot by the sniper. Indra tells Octavia that because she's the Chief's Second, she must make the other Seconds follow her. Atohl and Caris, the other Seconds, tell Octavia that they can't do anything until Lincoln takes out the sniper. Octavia comes up with a plan to block the sniper's line-of-sight so they can get to the wreckage where Abby and Kane are trapped and the other Seconds follow her and they start to dig out the survivors. She is overjoyed to see Lincoln return alive after taking out the shooter and looks on with pride when Indra finally welcomes Lincoln back into their clan. Later, she and Lincoln leave Tondc with Clarke, Lexa, and Indra for Mount Weather.
Octavia tells Clarke that she figured out that Clarke knew about the missile and is disappointed in her for letting all those people die and thinking she was going to let her die too. When Lexa tells the guard to kill Octavia, Clarke is able to stop the guard in time. Later, Clarke tells Octavia she wants to take her out of the mines and put her at the back of the battle so she won't get hurt but Octavia says no, stating she only listens to Indra and then ends their friendship by telling Clarke she only fights this war with her because she wants their friends back. She and Indra discuss the Tondc bombing and she doesn't understand why Indra isn't mad at Lexa and Clarke for letting all those Grounders die. Indra tells her it was the Mountain Men who were responsible for their deaths. They soon join in the battle cry with the Grounders around her.
Octavia travels into the mines with Indra, Caris, Jackson, several Grounders, and several Sky People to clear the mines of Reapers so Bellamy can get the delinquents and the imprisoned grounders safely out of Mount Weather. Later, Octavia thanks Indra for forgiving Lincoln. Octavia uses Lincoln's maps of the mines to find the way to the Mount Weather intake door. They eventually reach the door to Mount Weather and Indra tells her she's a Grounder now, much to Octavia's pleasure. They soon they hear the horn sounding retreat and Indra commands Octavia to leave the mines with them. Caris asks Octavia to leave with them but Octavia tells them she is not leaving without her brother. Indra tells her she is no longer her Second and symbolically cuts her. After Indra and the Grounders leave, Jackson asks Octavia to come home with the Sky People. Octavia tells him she has no home and Jackson leaves with the others while Octavia stays in the mines.
Octavia is waiting by the mine entrance to Mount Weather when Clarke appears. She and Clarke get in a fight because Clarke is desperate to get into Mount Weather and will bring unwanted attention on them. Suddenly, the door opens and Bellamy appears with Monty, Jasper, and Maya. They split up with Bellamy, Clarke, and Monty going after Dante and Octavia going with Jasper and Maya to get her to Level 5 before she runs out of oxygen. Once on Level 5, Jasper leaves them to go kill Cage Wallace and Octavia and Maya sit and wait for the all clear. They are soon interrupted by a kissing couple who run away and alert the Mount Weather guards. Octavia chases after them and takes out two Mount Weather guards with her sword and newly learned grounder moves. Octavia and Maya are soon chased into the Mess Hall and are quickly surrounded by Mount Weather guards. Bellamy sees her predicament and irradiates Level 5 with Clarke in order to save her. Octavia sits with Maya as she succumbs to the radiation until Jasper gets there. She then leaves to free the imprisoned Sky People. The next day, Octavia returns to Camp Jaha, holding hands with Lincoln.
