This is what i imagined before about her. Ya know her situation was like something out of x-men,another mutant person afraid and uncontrollable of her powers and i know for a fact that Charles Xavier could have helped her even better like all the others and tell her that her sister anna needed her and all.
Makes sense, since it felt like the team behind Frozen decided, "Hey, we own X-Men, but don't have the rights to make live-action movies of it...so we'll copy everything else for our next Disney Princessy movie."
It's an interesting idea, considering Elsa's situation in the movie reminded me a lot of Jean Grey's. Only it was she herself trying to suppress her powers, whereas Professor X was the 1 who did it to Jean when she was young.
