Kitty looks thoughtful for a moment. "It's hard to think you're one thing and then find out you're something else. Shifts your whole sense of identity." This is personal experience talking and she's sure it isn't exactly the same for Rey. Mutants were already well known and feared and hated when Kitty realized she was one of them. A freak. A monster. Different. Alone.

The titles changed over time and she has embraced being a mutant despite what Apocalypse tried to do to the name, but she remembers being that scared 13 year old girl who was just as likely to fall through a door as open it. She couldn't control it when she was so afraid of it and trying to deny it.
