I hadn't seen X2 till recently and afterwards I was asking myself why Jean Grey sacrificed herself. It just seems silly when Iceman could have just used his powers to freeze the water saving everybody. Am I missing something? What do you guys think?
Iceman was still learning his abilities. He wasn't as powerful as he is in the comics, but getting there. Jean used her abilities to power the jet and save everybody which was a big decision for her. Could there have been a way for her to live? Possibly yes, but she was already transformed into her Dark Phoenix persona.
