While the first season of The 100 was all about the children on Earth and the adults still in space, this season the adults have tried to take control of the ground. But in this episode, a few adults must decide if they can turn over the reigns and let the children lead them.
Alright, let's kick things off with the Clarke and Abby saga, which has been burbling over the last few episodes. On the one hand, we've got Clarke. She made her decision not to evacuate the village before the missile hit, and now she's witnessing the consequences. The sight of everyone around her blending, burning, and dying because of her refusal to warn them is a bit much for Clarke, so she decides to assuage her guilt with action. She tracks down Mount Weather's spotter and kills him, but it doesn't make her feel any better.
Meanwhile, Abby is trapped beneath rubble with Kane, who is in danger of being crushed to death. Abby is apparently the worst secret keeper in the world, because, despite her promise to Clarke, she tells Kane that Clarke knew the missile was coming. Kane is a lot more philosophical about Clarke's decision than Abby is. After all, they used to kill off folks on the Ark all the time. Kane understands making the decision to let some people die for the good of the many, and after her experience with Clarke's father, Abby understands it, too, even if she's been resistant to seeing her daughter making those decisions. But after her heart-to-heart with Kane, she's willing to accept Clarke's leadership, even if she mourns for some part of Clarke's soul.
Grounders, of course, handle things differently. It doesn't matter that Octavia is a teenager or that she's a Sky Person, when Indra is injured, she orders her second to help the others in the village. And Indra's decision to make Octavia her second is looking smarter and smarter. Not all the Grounders love that Octavia is among them, but they seem to trust her. And when help comes from Camp Jaha, there's no time wasted debating what the Sky People's motives are or what their tools can do. Octavia just puts them to work. She's an ideal liaison, and her stronger loyalty is probably to the Grounders.
The most interesting things in this episode, though, are happening under Mount Weather. That's where the remains of the 47 are making their stand and Maya is finding her voice. Maya's got a worried parent, too, a father who was once part of a movement against this whole blood-stealing business. It turns out that Maya's mother died because she refused treatment after a radiation exposure. And it's clear that Maya's dad is nervous about losing his daughter just as he lost his wife. (I can't fault him; Maya strikes me as ripe for death.) But he can't fault her values.
Between Maya's leadership and President Wallace's influence, the remaining 47 and the caged Grounders may have a shot at freedom. It turns out that not everyone beneath Mount Weather wants to be a vampire, especially if it involves killing innocent kids. When Clarke and Lexa march on Mount Weather, they won't just find an army; they'll find a civil war.
