Sky People/The Second Culling

"This is how we save our people."

- Marcus Kane after he and Jaha gassed the bunker. The Second Dawn Culling, was an event that was necessary for the Sky People's overpopulation crisis caused by Bellamy Blake letting in 1,100 grounders to share the bunker equally.

Background
Back in Die All, Die Merrily when Luna announced that she was going to compete in the final Conclave, Clarke Griffin and Jaha improvised a plan to secure the bunker for the Sky People since they feared that Luna would easily win the Conclave. After Bellamy took down Echo from cheating in the Conclave, he was attempting to sneak back to Polis without being caught. However, an unidentified person snuck from behind and made Bellamy pass out. Later in the episode, Bellamy wakes up and to his confusion is in the bunker seeing Clarke, Jaha, and, Abby. Bellamy questions Clarke and Clarke says that she did what she needed to do by securing the bunker for the sky people's survival.

In The Other Side, Bellamy starts to furiously accuse Clarke and Jaha of the unfairness of the act and demands that they let everyone in. Jaha then tells Bellamy that if they open the door, they will be killed by the grounders. Bellamy then states that the only way that they can stop him from opening the door is by killing him. Then Jaha cues Nathan Miller to shock Bellamy and locks Bellamy in the turbine room. Later, Clarke asks Murphy to try to talk to Bellamy. Murphy goes to the turbine room and sees that Bellamy's wrists are bleeding due to him trying to escape. Murphy talks to Bellamy and Bellamy tries to tell him to set him free but, Murphy ends up leaving the room and Bellamy screams in anger. Later, Abby comes down to aid Bellamy's wrists and than Bellamy coaxes her to help him escape. A little later, Murphy comes down to check and Bellamy and is injected by Abby and he falls unconscious. Bellamy runs to the bunker entrance door and simultaneously Clarke realizes that Bellamy escaped and rushes towards the bunker entrance. Then when Bellamy was going to open the door, Clarke aims the gun at him and tells him to not open the door. Bellamy refuses and Clarke fires a stray bullet to show she was being serious. Bellamy says that the only way to stop him is to shoot him. Clarke shaking aims the gun at Bellamy but, gives up and aims the gun down letting Bellamy open the door. Bellamy then proceeds to go outside and sees Octavia and Indra. Bellamy hugs Octavia and tells her that he loves her and Octavia says "I knew you could do it."
