The only thing I agree with here is the killing of non-white characters. As for the conflict with the Grounders, I think it's worth pointing out that the Grounders did attack The 100 without any giving any kind of reason or warning. They've been pretty aggressive all pretty much from the beginning. Most of the violence probably couldn't told The 100 that they were in their territory and asked them to leave. I actually thought this was a pretty good season finale, although I do wish Jaha had stayed on the station and made it to the surface. We got some pretty good action scenes down on the surface, and I thought the end was a great twist. I wonder if Octavia will be a full on Grounder when we see her again next season? It'll also be interesting to see what happens when the people from the Arc make it to the remains of The 100s community. I'm assuming they'll think that the fried bodies are the kids.
