When Bellamy tells Clarke that he can’t leave again without his friends, he explains her that leaving her behind killed him. He did it though, because of her. Cause he HAD TO, she wanted him to, and he used his head, and didn’t stay with her. He left to save their friends. But being that selfless killed a part of him. And he can’t be that selfless anymore : he prefers to sacrifice himself with his friends, rather than save himself without them. By being selfish, he manages to be the most selfless of men.
I’m sorry I couldn’t respond all those years...I know it sounds crazy, Madi, certainly thought it was, but talking to you everyday, even though you didn’t answer. It kept me sane. It’s not crazy.
