I'm assuming that Twilight has been in motion from the first page of the comics. The world is all different now. It was just subtle off-ness at first that is now a very unsubtle off-ness. Like Buffy says in the first scene something smells rotton.

Not sure I follow your last sentence. Are you talking about their reaction to Spuffy sex? They aren't some extra-story commentary on what we are supposed to think. They are in-story characters with issues of their own. Bro and I will be hitting that theme a lot in the notes as we go forward. The world didn't end when Buffy had sex with Spike; and for that matter her friends didn't harsh on her for it. What she got was a vampire who went out to fight for a soul and used that soul to save the world. That's not punishment.
