Hello everyone. I have been a lurker for a while but I felt the need to answer this question. I am 30 and have been reading x-men all my life just so that I can read more about Jean Grey and Rachel Summers (not Rachel Grey. They don't write her correctly anymore)

I believe that in the Ultimate X-men, she used her telepathy to operate on some one. She has never been a doctor in the comic universes.

Hank McCoy was originaly intended to be in the first x-men movie but they had to cut him for budget reasons so they combined his and Jean's roles.
