This episode centers on four groups of characters: Kane and his mission of peace, Clarke and the Ark survivors meeting and aftermath, Finn's quest to become crazy and some shady things at Mount Weather. It all together makes for another good episode for the series.
Clarke's back, and angry. The people from the Ark are trigger happy and it has had bad consequences. And Finn and Murphy are still out there, and who knows what Mu... Finn can do. That Murphy, yeah, the mean-as-hell Murphy is the voice of reason in this episode says a thing about Finn's obsession with Clarke. Once down a path, it is very difficult to come back.
But the show has lots more to offer. Kane's mission to make peace with the Grounders is nicely done. Kane is showing he can be stupid, but at least he's not heartless, and he knows that the path his govern was going down was a bad one (Finn should talk with him).
And then there's Mount Weather. Monty is getting smarter and Jasper... well, he seems to be in love. That gives the chance to the people at Mount Weather to plan something bad... very bad. Will they get through with their plan? Well, if not, they still have Lincoln and their quest to make him a Reaper. They are becoming more than just a big bad. They are becoming a lunatic big bad. And there're no more dangerous foes than the crazy ones.
Great acting, good action, and many more things to come. Right, Jaha?
