Complete story — includes the ending
Clarke helps Abby after her overdose and McCreary orders her to get her mother operating again, and says that if she still refuses to cure them, they can both watch their daughters die. Raven, Emori, Murphy and Echo head out to scout ways into the valley (Octavia's army will arrive in 5 days). Raven tells Shaw to stay behind. Shaw follows the scouting group, and after Murphy suggests they steal the ammo rather than just scouting, they get ambushed, and Shaw saves them. The truth of the dark year in the bunker is revealed - they do not have enough protein until another year, so they have to get it from the fighting pits. Clarke and Abby cure McCreary's people and Madi confronts Clarke, telling her they are on the wrong side of the war. Bellamy tells Octavia about the safe way into the valley, as long as she agrees to his terms - accept McCreary's surrender and share the valley - to which Octavia agrees. Diyoza and Kane go to McCreary and tell him that Wonkru will win because they know every move he is going to make before he makes it but they will tell him how to win the war.
