Bellamy and Octavia

Bellamy and Octavia is the relationship between siblings Bellamy Blake and Octavia Blake. They are portrayed by starring cast members Bob Morley and Marie Avgeropoulos and début in the first episode of season one.

Because of the one child law on the Ark, Bellamy and Octavia are the only known siblings among the Sky People.

Summary
Bellamy's and Octavia's sibling relationship starts before the first episode of season one at Octavia's birth. After Octavia was discovered and locked up, Bellamy shot Chancellor Jaha in order to stow away on the Delinquents' drop ship so he could protect his sister on the ground. Throughout Season One, Bellamy is overly protective of Octavia to the point of them getting into numerous fights. Eventually, he acknowledges his sister is stronger than he thought and in We Are Grounders (Part 2), Bellamy says goodbye to Octavia and allows her to leave with Lincoln after she is injured in the war.

Bellamy and Octavia are re-united again in Season Two when Octavia saves him from Grounders in Many Happy Returns. Bellamy then helps Octavia find Lincoln and treat him through his Reaper drug withdrawals in Long Into an Abyss. After Bellamy infiltrates Mount Weather with the help of Lincoln in Survival of the Fittest, Octavia refuses to leave him behind, sacrificing her chance to be a Woods Clan warrior in Blood Must Have Blood (Part 1). Bellamy then saves her life by irradiating all of Mount Weather in Blood Must Have Blood (Part 2).

Throughout the Series
{{Scroll-1| In Pilot, Octavia Blake is sent down to Earth with the other delinquents. When the drop ship 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. Octavia 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. Bellamy holds back the other delinquents as she steps foot outside the drop ship and onto the ground, becoming the first "grounder" in 97 years. Later, Bellamy is reluctant to let Octavia go search for supplies in Mount Weather but she promises him that she will be fine, gives him a kiss on his cheek, and then leaves.

In Earth Skills, Octavia returns injured from their failed trip to Mount Weather. Bellamy helps clean her leg wound and bandages it. 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). Bellamy leaves Atom to watch over her and keep her from getting into trouble. Octavia quickly begins taunting Atom, saying how he can't not follow orders. Atom gets fed up and locks her in the drop ship with Monty. When Atom eventually lets her out of the drop ship, Monty asks how someone who was raised under the floor isn't a basket case. Atom tells her it's because she was loved by her brother. Octavia then wanders off following a butterfly and discovers a field full of them. Atom follows after her and Octavia kisses him. When Bellamy returns to camp, he catches Atom with Octavia. Bellamy punishes Atom by tying him up in a tree and tells him he will not be disobeyed before leaving him there for the rest of the night.

In Earth Kills, Bellamy orders a search for Trina and Pascal who have been missing for a while. He is confronted by Octavia because he punished Atom for kissing her. Bellamy leaves camp with a group of [{Delinquents]] to search for the two missing kids while Octavia remains behind and watches over Jasper as he recovers from his wounds. During the acidic fog storm, Octavia expresses concern for her brother because he's out in the woods. Bellamy manages to rescue another delinquent, Charlotte, and they make it inside a cave before the fog reaches them, however, Atom isn't with them. While in the cave, Charlotte has a nightmare and starts to scream. Bellamy tells her the same things he had told Octavia while growing up and that she can't be afraid because fear is death. He gives her a knife, telling her to "slay her own demons" as well as telling her to repeat the phrase, "Screw you. I'm not afraid," whenever she's afraid. Once the fog passes they set out in search of a missing Atom. They find him dying; his eyes are a pale, gray color and his skin is destroyed from where the fog touched it. Atom begs Bellamy to kill him and Charlotte hands Bellamy the knife he gave to her, telling him not to be afraid. He sends everyone back to camp and tries to bring himself to kill Atom. Clarke arrives and realizes there is no hope for Atom. Bellamy watches as she takes the knife from him and humanely kills Atom. Once back at camp, he tries to protect Octavia from seeing Atom but she does anyway and becomes upset.

In Murphy's Law, 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 John Murphy about it.

In Twilight's Last Gleaming, Octavia watches the Mir-3 escape pod crash to earth with the other delinquents and Bellamy tells them 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, claiming that she didn't ask him to do that for her, 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.

In His Sister's Keeper, their early life is revealed through flashbacks. In their present Timeline, Bellamy realizes that Octavia has gone missing and forms a search party in an effort to find her. They soon see a spectacular meteor shower, which Clarke realizes is actually a funeral for 320 people from the Ark. Bellamy brushes off Raven's accusations that it is all Bellamy's fault and he quickly takes off with a group of delinquents in search of Octavia. Once Bellamy and the rest of the search party are in the Grounder's territory, they are quickly under attack.

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.

After Mbege, Diggs, and Roma are killed by grounders, Bellamy, Finn, Jasper, and Monroe soon find themselves surrounded. A horn is heard in the distance and Finn, believing it to be Acid Fog, quickly sets up a tent and they take shelter under it. After a few minutes, Bellamy looks outside and finds no acid fog. They spot a Grounder running through the forest and they follow him back to his cave.

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 enter the cave. Bellamy quickly frees Octavia and threatens to kill the grounder but Octavia tells him that the Grounder had saved her life. While they argue, Finn notices the Grounder's horn and reaches for it. The Grounder stabs Finn in mistaken self-defense and a fight ensues with the Grounder pinning Bellamy down. Octavia begs the Grounder to not kill her brother right before Jasper knocks him out. Bellamy then hugs Octavia and they carry Finn back to The Camp. Once back at camp, Octavia tries to leave again, but Bellamy stops her. They get into a heated argument, blaming each other for their troubled past. Octavia walks off and Bellamy notices that a storm is coming.

In Contents Under Pressure, Octavia is 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 Bellamy makes Octavia leave when she protests the treatment of him. Bellamy beats the Grounder, trying to get information about the other Grounders. He looks through the Grounder's bag and they find a tin full of vials and a journal. In the journal, Bellamy sees a drawing of Octavia and is not pleased. He then sees a drawing of the drop ship and tally marks representing the number of delinquents with ten crossed out for the ten deaths that had already occurred. When Clarke discovers the blade that stabbed Finn was poisoned, she heads up to see the prisoner and Octavia follows her. Bellamy tells Clarke she doesn't have to be there while he tortures Lincoln to find the antidote, but Clarke stays. Octavia begs him to stop, telling him the Grounder had saved their lives even though Finn was dying downstairs. Bellamy brutally tortures the Grounder, whipping him with a seat-belt and putting a spike through his hand, yet the Grounder still will not speak. Raven comes into the room after Finn almost dies again and begins to electrocute the Grounder. Octavia makes her stop when she slices open her own forearm with the poisoned blade, saying that the Grounder wouldn't let her die. The Grounder finally reveals the antidote in order to save Octavia's life. Bellamy tries to comfort his sister but she rejects him.

In Day Trip, Bellamy is unsure what to do with Lincoln but has decided against killing him. Bellamy still won't let Octavia see Lincoln and leaves Miller in charge on the pretext of going on a scavenging mission with Clarke. In reality, he is planning on running away and leaving Octavia behind because he knows it is just a matter of time before he is punished for shooting Jaha. While he is gone, Octavia helps Lincoln escape. After Bellamy returns from his trip with Clarke, he asks Octavia about Lincoln escaping. She replies by lying, saying she had nothing to do with it. Bellamy wraps a blanket around her and promises her that he's not going anywhere.

In Unity Day, Bellamy recruits Raven and Jasper to accompany him as Clarke's backup to the meeting on the bridge with the grounders. When the meeting begins, Bellamy witnesses Octavia hugging Lincoln and is not pleased to realize his sister lied to him and freed the Grounder. Soon after, Jasper spots grounders in the trees and opens fire. Bellamy witnesses Lincoln taking an arrow for Octavia and they all flee back to The Camp.

In I Am Become Death, Octavia, Connor, and Derek discover Murphy outside The Camp walls and bring him inside. He has been severely tortured by the Grounders and managed to escape when they "forgot" to lock his cage. As the delinquents start getting very sick, they realize Murphy is carrying hemorrhagic fever. 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 Octavia. Once Bellamy leaves, Clarke sends Octavia back out to go talk to Lincoln and get a cure. When Octavia arrives at Lincoln's cave, he is happy to see that she is unaffected, calling her strong. He states there is no cure and that Anya uses the virus to weaken their opponents and she's planning to attack the delinquents at dawn. He also asks Octavia to run away with him across the sea to another clan that would take them both in. His people think he's a traitor because of Octavia. Octavia decides to go with him but first she needs to warn her people of the impending attack. Octavia returns to the camp and tells them there is no cure and that the Grounders are attacking at dawn. Bellamy works with Raven and Finn to come up with a plan to give the delinquents some more time against the grounders by blowing up the bridge. Bellamy becomes infected and begins coughing up blood, having to pass his job in the mission on to Jasper. Octavia takes care of Bellamy throughout the night, making the same promises to Bellamy that he made to her when she was first 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.

In The Calm, 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 ignores her warning. The Smokehouse catches on fire and there is a fight going on between Murphy and Del. Bellamy breaks up the fight, and is told by Octavia that all of the food was in that shed and it was Del's fault. Bellamy and Clarke decide that to survive, they must go hunting. Later, Bellamy, Monty, Octavia, and Raven are searching through the forest for for Clarke and Finn, both of whom never returned from hunting. They find an injured Myles and bring him back to camp, giving up on finding Finn and Clarke.

In We Are Grounders (Part 1), When a delinquent misfires and accidentally wastes a bullet, Bellamy freaks out and shakes him and Octavia tells him that he is scaring people. Later, when Murphy begins to threaten Jasper, Bellamy overhears on the radio and runs to the closed doors of the drop ship and uses the walkie-talkie to talk with Murphy inside. Octavia 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. Murphy tells Bellamy to tie a noose and Bellamy apologizes for kicking the crate out from under Murphy for Wells' murder. Murphy says he wants Bellamy to feel what he felt and he makes Bellamy put the noose around his neck and tightens it. He then kicks the crate out from under Bellamy. Raven gets the drop ship door open just in time and Octavia is able to save Bellamy and encourages him to breathe.

In We Are Grounders (Part 2), Octavia is in the midst of fighting in the war when she saves Bellamy's life after a Grounder attacks him. She is hit in the leg with an arrow and Bellamy is unable to get her back to the drop ship. Lincoln appears and Octavia is glad to see that he is still alive. Lincoln tells Bellamy that he can save her if they leave right away. Bellamy gives Lincoln his blessing to save Octavia. Octavia is deeply upset that she has to leave her brother and they exchange goodbyes before Lincoln carries her away. }}
