Yeah okay so to ACTUALLY answer your questions: there are a ton of different universes. I was pulled from a supernatural one. And like, Vallo sucked in a bunch of different options which is how you arrived here. Just like we don't know how we got here, we don't know how to leave, but like... time stops in your home universe, and/or it continues without you being there but another COPY of you is there and idk I'm not a scientist, but basically things are cool?
