The big reveal of Twilight (the Big Bad of Season 8) went down in Buffy this week, and you can read the fallout here. My only real gripe right now is that I wish they had never done a 'season 6' of Angel in comics. I always felt that the show ended on about as perfect a note as possible. The mystery over whether Angel (and crew) died in the alley in L.A. would have made the reveal of Twilight as Angel that much more shocking, to me at least. It would have sold some of the conflicting emotions Buffy experiences a bit better for some of the people that VIOLENTLY disagree with what happens in this issue.
For what it's worth, here are my two cents:
Buffy does try to kill him first. With a giant tree.
Giles and Angel know something we don't.
If this is Angel - IF - he's found a way around their 'perfect joy' issue (and daylight!) and I can totally buy that he doesn't really mind who dies because of it.
And it would be a lot more confusing/OMG/WTF? if this had been the first time we had seen him since that cut to black in the alley.
