If in previous episodes we had had the action centered on Arkadia or on the 12 tribes, in this episode we get a little bit of both. And the better for it.
For starters, after Lexa's death, there is the little problem of succession, and what is going to happen when a new leader rises to power. Is it going to be one that thinks the Arkadia people are ones you can negotiate with, or is it one that believes the "lay waste to your enemies" is a great motto to start your day with? Even if it is pretty easy to see where the episode is going, it is nicely done, and the action and tension are high.
On the other side, not willing to be looked down, Kane's coup and punishment conundrum. We have Pike getting madder and madder, and Bellamy starting to think that now, that his own people are taking the brunt of the tensions, things should change. It is Bellamy being at his most Bellamy: naive, not much constructive thinking, and act before recognizing that maybe thinking is not a bad idea. Is Kane going to be killed? And also the ones that were in with him? The episode keeps us on the edge, and the outcome is, maybe not surprising for some, but not something that can be seen from a mile away, and shocking.
Good episode overall, and things happening non-stop.
