You have made my day, even if this chapter is extra creepy. If it is really Buffy though, would she be trying to do what Willow did after Buffy died? Only with alot more blood...
I like how you got the adult's POV across. While Dawn is worried about "failing Buffy", they are worried that she is going to leave them without letting them know and get hurt again. After all, they don't really know the full story and probably think that Buffy "let it happen". Or something like that.
