Yeah, Angelus thought he would get away with killing Jenny because he didn't bite her. But for Buffy what made the difference was the killing not the biting. (I like the non bite explanation / the part of the story with Spike and the other slayer.) So Spike would leave her if Buffy wanted it? Even if it would make her unhappy. ~ And now she has to save Giles.. and dust Angel?

Author's Response: Angelus is an arrogant self-centered SOB, but then we all knew that! I think Spike is taking into consideration not only what he thinks is best for Buffy, but Buffy's wishes as well when he offers to leave. Sometimes love means sacrificing what you want for someone else's benefit.
