Will there be more to Magneto wanting to kill the Wasp in Uncanny Avengers? If she is really the last human left alive I just don't see why he's bothered. Humanity will be dead in one generation and her offspring if any will likely be mutants themselves. I'm far from a Magneto apologist but the press release is sounding pretty out of character for him. He even made a move on her himself at one point.
Again, you’re asking about a story that hasn’t seen print yet. It’s fine to be concerned about such things–but the only answer I’m going to give you is “Wait and see–it’s out in a few weeks!”
