I agree with you about Gambit. He needs to hit up Bella Donna and make it official again.
I think it would add a new level of trust/danger to Rogue's character if she could control her absorbtion powers. She could no longer use the excuse that it was reflex, and all characters everywhere would have to trust her when they decided to touch her.
I love how Mike Carey has given Rogue a renaissance. He has left out the romantic angles for now, and I think he will handle any in the future excellently. My only fear/concern is that when/if he leaves the Xbook is how the new writer will treat Rogue. I suppose I could deal if she took more of a backseat, but if anyone ever retcons any of the current stuff I'll be livid! I am SO glad that Grant Morrison didn't get her for New Xmen because he was going to kill her off!
