"A witch? Fascinating." As far as Charles knows, that isn't a thing in his world. He could be wrong, he doesn't know everything, but he probably would have come across someone else in the astral plane if they did by now. He has no reason to doubt her.

"I'm a mutant. As far as I know in my world, we're the only supernatural entities." There are no Avengers in his world, no gods or demons or creatures. Just the mutants and the humans who hate them.

"I can meet you somewhere if you'd like to meet in person."
