Re: Patrick Stewart & Ian McKellen Return for Days of Future Past
See, I don't see how The Last Stand can be apart of this continuity. First Class already established that Xavier is paralyzed when he and Magneto were in their mid-to-late 20's. Also, let's not forget that Moira McTaggert already exists in 1962. If Xavier was not paralyzed at the end of First Class, then I can see them trying to put all of it together and retconning Dr. McTaggert as someone else.
I can't see anyone bringing this up as blowing things out of proportion or being too analytically since Xavier being paralyzed and Xavier/Magneto meeting young Jean Grey were both pivotal scenes in their respective films.
