The Genosha Massacre, I faintly recall that. I could probably find it in TPB I suppose.
I did know she joined up with the X-Men and Scott through things like Wizard. It seems she may be going back to her dark side. I saw art where she was at a villian round table for Dark Reign. Of course Namor was there also so I guess he has another itch to scratch against the "surface world". Wonder what has Emma crossing back over.
