Parallel Realities?

"Parallel realities?" Karyn asked. "I don't know, Jon. I think we messed around too much already." "Come on, Karyn. This is the only way to change you back." "But it won't be *me*, Jon. It'll be the *other* me." "But you'll be coming with me." "So, there will be *two* of me?" Jon hadn't thought of that. It would be weird to have two Karyns. But maybe there was a way to fix it so that *this* Karyn could still travel there and have her original appearance. "I think I know a way of fixing that," Jon assured her.
