This is touched on in FFL--"You're a little bit in love with Death... and one of these days, I'm gonna slip in there." And then, of course, he does. He represents peace and death and completion for Buffy, and on a really bad day for her ("You came back wrong")--he slips in there, and gets her to admit that she does desire death.
Funny that, in SR, when he realizes that he did in fact hurt Buffy, as he was sure he'd never really do--funny that he goes and seeks his soul. He finds a way to not hurt her. He finds a way to make sure that it's his death, his destruction--not hers--that will come from it all. He destroys himself because he wants to, and also because he doesn't want to destroy her. <3
Anyway. Beautiful symmetry those two have.
Second thing. I got Final Cut Express today! I'm so excited and terrified. And I'm having a bizarre flood of vid-inspiration (vidspiration?) all circling around They Might Be Giants songs. Weird, huh? Anyway. If anyone knows of some good tutorial sites especially for Final Cut, I would be eternally grateful.
