Basically what I hope happens after part one of the finale (of the 100). I love the idea of Clarke and Lexa so they're going to be endgame in this. This is basically just to take the sting off of Lexa's betrayal. Whoops, spoiler! There will be more of those in here.

Clarke and Lexa have finally freed their people and gotten together, but their life is never that simple. When a new enemy arises and joins an old enemy, will their people's combined strength be enough? Or will they lose everything they love?
