Re: What would you rather see next - FIRST CLASS 2 or X4?
Rogue should definitely get an upgrade once her powers return. If not a direct side-effect of the vure wearing off, she could come into contact with an unfortunate soul and drain them.
The repercussions of the faulty cure would massively damage Human/Mutant relations. I think it should be used as the catalyst for new defensive measures against mutants (Sentinels etc). Fun fun.
