There’s no going back after this week’s episode of The 100. The entire second season thus far, treatment focusing on the Sky People and the Grounders’ fight against Mount Weather, decease all leads up to this moment.

Just as their united front finally gains the upper hand, with Bellamy (Bob Morley) on the inside and Raven (Lindsey Morgan) listening in, a new development threatens to undo everything they’ve achieved. When Raven hears Mount Weather is planning to use a missile, Clarke (Eliza Taylor) and Lexa (guest star Alycia Debnam Carey) must decide whether to evacuate and let the Mountain Men know they have a spy or sacrifice some of their people instead.
