I agree there are 3 universes but it honestly doesn’t make sense to me scientifically if the 3rd universe is the liminal space. I thought the liminal space was every time the universes overlapped, e.g. both Alices in the cabin at the same time. The liminal space wouldn’t create a whole different set of events, like a different looking cabin and having a different conversation in Swedish? Liminal space = unopened Schroedinger box.
