"What do you mean what am I doing here? I'm a hero", she whispered back. Sure she was going against her Professor, but her abilities were her own to do with as she liked...and she wanted to help. She had something to prove, to herself and all the victims of those she had killed days ago. Jean couldn't get them out of her mind, the burning around her and the fading of their faces as it ate them up...not even kind enough to leave ash. She didn't understand...she wasn't sure she wanted to even. What was within her that could be so evil? Was she hoping that by being around superheros she could somehow clean her tainted soul?
No...but she had to make herself belive that she hadn't enjoyed what happened. She had to make sure she was fully Jean Grey and not something else entirely...not a monster.
