Although I can understand, like with GOT, that a lot of fans want their happy end for their favourites. But I liked this twist, it was not the first time in the show that Clarke made a big sacrifice, the same that Bellamy, in his twisted mind, was willing to make here. These things happen when belief is stronger than reasoning. It was a strong episode, and Clarke displayed how hard it was for her. Their world is a dark & cruel place, and non of the people who dislike this episode would probably survive very long in it. I like the unexpected, even if it kills off characters I love. It's dark science fiction and not a soap opera.
