Wesley for me... He came into the show as an outsider, and he was never accepted and treated with respect on BtVS, then on "Angel" when we got his back story to find out what kind of family life he had, it was easy to see why he craved acceptance and love and friendship so much. Once he got it, I rooted for him and Fred; that he might have a romantic relationship was something with someone that seemed made for him seemed like something he deserved on such a deep level. And then the way it all turned out? It was pure tragedy.
