So the idea from Ishmael's uptie story is that, the mirror world, no matter how nonsensical it might be for it to be a thing, will become available anyway so long as someone wished for it? Meaning, it's not technically a real possibility that could have happened by itself, but just a world that exists because we wanted to learn more about the person in question, and now how it was possible for our sinner to end up in their role?
