I think there are definite Wesley overtones as well, as Joss has done a reverse Season 5 on Kitty by giving her hideous memories rather than erasing them.

Yes, those were the Wesley parallels I was thinking of. Also between the way he treats the prostitute in s4, knifing her hands, and Kitty's actions here.


Resurrected to become a killer? Colossus is a vampire?

Well, the panel where he clutches at Kitty and says "can I finally die?" back in Gifted is a direct parallel to the shot with Buffy and Angel in "Beauty and the Beasts". Mind you, the turning upside down of prophecies is also a Jossian tradition...
