The last page was beautiful, both artwise and character-wise. I read the last lines as Jacob, as he said, daring to want more, to finally get Alex, to dare to feel.
Vampires aren't just monsters. They're part human too, and a few of them might even be decent people(if they have access to willing-to-be-feed-on people).
That's one of the things I love about Buffy. It's not always white and black.
That said, I think Jacob needs to be slayed.
