Complete story — includes the ending
Bellamy is letting the grounders imprisoned inside Mount Weather out of their cages as Cage starts to raid the complex for the 47. Some of them are temporarily captured but freed again by Bellamy, Jasper and Maya, who bring them to the harvest chamber. Soldiers soon raid the harvest chamber too, taking the 47 prisoner once again. Cage visits his father, desperately hoping he will tell him a way to stop the incoming attack. Raven and Wick destroy the mountain's generators and the lock on Mount Weather's door is disabled. When they pull the door open. Lexa commands her people to stand down – she has made a deal with Emerson, her people will be freed if the grounder army retreats leaving the Sky People left for dead. It is later learned that this was Dante's suggestion. When the grounders retreat, almost all the Sky People accept defeat and soon leave too, leaving behind only Clarke at the front door and Octavia in the tunnels.
