Complete story — includes the ending
Raven, unconscious, has made it to the ground. Bellamy reaches her pod first and throws away her radio as he was the one to shoot Jaha and fears repercussions from his actions. Clarke and Finn follow, and help Raven, who is revealed to be Finn's girlfriend, leaving Clarke devastated. They catch up with Bellamy and tell him of the 300 people to be culled from the Ark to preserve oxygen. He helps locate the radio, but it cannot be repaired in time, so they devise a plan to fire "flare" rockets that the Ark will see, confirming that Earth is survivable. On the Ark, the approved plan calls for sealing off and deoxygenating Section 17. A desperate Abby reveals her husband's discovery to the Ark, causing some residents to volunteer for the culling. After the culling, Abby, imprisoned, and Jaha watch in surprise as the "flare" rockets appear in the viewport above Abby's cell. Octavia is captured by a grounder.
