It depends. I don't really get all the technical details... But usually, things like this happen because something's gone wrong. Either someone did something they weren't supposed to and caused a big problem, or someone needs help badly enough that they're calling in people from other universes! And either way, the best way to get back home is to help fix whatever's wrong.

[ he has a very simple view of the situation, for sure. If helping Qri doesn't fix the problem, then defeating her probably will, in his mind. ]
