[Perhaps not all his expertise. Loki has met a few others around the resort that have some knowledge of the multiverse. And considering most everyone here is from a different universe or timeline, it must be pretty evident to the residents of the Hotel that the multiverse is a real and true thing. Even if Loki understands that it’s not an easy idea to grasp. But if Scott asks, he will do his best to explain.]

Yes, that is precisely what it is. When time travelling, there are certain pivotal events that cannot be changed in that line. Of course, other branches may appear and result in a whole new timeline, but in that original line, those events remain.

[It all gets a bit message beyond that because there are so many options, so many things that can change before a fixed point is reached that it never stops a new branch from growing, and he wonders how much of that is different now that the TVA is not pruning new branches, but that is something he’ll have to investigate more once he returns home.]

[ooc: Excellent! I think all Loki really knows is that Jean is dead and it wasn’t from natural causes. But yeah I imagine he would’ve heard of Apocalypse just because they did seem to commiserate quite a bit. Thanks!]
