Agreed! This was an excellent issue all around, and shines new light on old character. In a stroke, Peter David has taken (what I think we'd all agree has been) decades of bad writing for this character and made it make sense. And it adds complexity to Lorna, Lorna's relationships with those around her, and to Magneto.
If Mastermind wasn't already dead, I'd kill him again!
Mastermind sure has messed with X-women, that's for sure--Jean and Lorna.
But, I'm wondering what happens to Lorna that Alex leaves her to join the Avengers? How can he leave her after this? Or maybe she leaves him. That's going to be interesting.
