I agree utterly that kinship makes the love. I mean, Buffy? Buffy was the kid who made my life hell, she's the one with influence who gets wrapped up in herself and steamrollers over other people. I can't sign up to be with Buffy. Faith, otoh, I can see the reasoning in. I can get that feeling of being Outside and knowing that you're never going to be like the cool kids. I might not have killed anyone, but I did that thing of one day going "Fukkit, they hate me anyway, I'm not gonna repress anymore." And I've seen that Buffy/Faith dynamic so many times getting people fucked up.

Earshot, when Buffy tells Jonathan off for being miserable? I'm Johnny, and I wanted to kill her.
