I would question that last statement. Living in a suit, with fear of a break in protection as your constant companion? And fearing for others transitioning? Worse, of course, if you don’t know that mutation while unconscious makes you a mutant and not a monster. Jim & Sarah did not know.
But they did know (or believe) that becoming a mutant will get rid of Sarah’s cancer. That woould cause some resentment, too.
Keep talking, lady! This is interesting.
