I agree with you, but just on principle just the word "copy" makes me nervous - think what sort of hysterics it sends Marvel into! (Although, truth be told, they created this mess by allowing things to happen in Volume 3 that never should have passed by the editors...)Who created her? Was it Roxxon? Conceivably there could be another copy of her somewhere.
What is amusing to me is that the main thing that Marvel and Alpha Flight have in common is creating their own "worst"s - Alpha Flight creates its own worst villains, while Marvel creates its own worst problems with some of the crap they put out and then they blame it on the characters or on the fans!
