Professor Charles Xavier:
Heterochromia was in reference to your eyes which I have to say are stunning. One green, one blue. It's a mutation. It's a very groovy mutation. I've got news for you, Amy. You are a mutant.

Professor Charles Xavier:

Co-Ed:
Then let's reclaim that word. Mutant and proud.
