On second read though, I'm almost positive its Joseph because of the dialogue. What do you call those who refuse to stay dead sounds exactly like him trying to sound like Magneto, lol, while the whole point of Magneto being dead in the X-books is because he COULD return, but he chooses NOT to, for various reasons. There's no 'refusal to stay dead' with Magneto....if there was, he would have been back a long time before now anyway, because literally the only thing stopping him from returning is he didn't want to.
