1 - Doyle: I don't see Angel putting on tights. ...Oh, now I do and it's really disturbing.

2 - SPIKE : It’s bollocks, Angel ! It’s your brand of bollocks from the first to last.
ANGEL : No, you can’t ever see the big picture. You can’t see any picture !
SPIKE : I am talking about something primal. Right ? Savagery. Brutal animal instinct.
ANGEL : And that wins out every time with you. You know, the human race has evolved, Spike !
SPIKE : Oh, into a bunch of namby-pamby, self-analyzing wankers who could never hope to-
ANGEL : We’re bigger. We’re smarter. Plus, there’s a thing called teamwork, not to mention the superstitious terror of your pure aggressors !

WESLEY : It just...sounds a little serious.

WESLEY: Yes.
CORDELIA: Well, that was dumb. What'd you ever listen to me for?
WESLEY: I don't know. I think I sort of missed this. You and me and the books, kicking it old school, as they say. (Pause) And I never will again.
