It seems that Jean/Phoenix joins with Magneto in X3, but why would she do this? From the trailer it seems at though Jean is bitter and angry at Professor Xavier for repressing her powers, but why go to the extreme of harming humans and total mutant supremacy? Jean never showed signs of wanting that before? And it seems like an extreme way of getting revenge on Xavier. She's all powerful, so why does she NEED Magneto? Is she being manipulated by Magneto the way Mastermind manipulated her in the comics? Could Magneto of promised her a way of reviving Scott if she joined with him? And when she finds out he was lying, she turns on him? Any opinions on this would be welcome, I like hearing all different ideas and then finding out who was right when the movie comes out!
