Interestingly enough, Kitty @ Buffy made me actually give a hoot about Kitty again, after years of remembering her as "Kitty - that intangible chick who was in Uncanny back when and then... went to fight... with Excalibur? And the... Shiar, or... Magik, or something? Was she around in Onslaught? Eh, nobody cares about Shadowcat anymore."
Moreover, at this point she's not 16 to his 23 or whatever the old squick was, so it's all good and well.
