And what with all those ANYTHING can fit into canon. Different timeline, different dimension, crossovers between them, it’s magic without limits, or at least whatever is plot convenient limits … profit!
Don’t get me wrong. I enjoyed Legion’s weirdness. I get the sense of how old sit coms were the place to escape from reality, and who knows what rehashed shows Wanda grew up watching? It makes logical sense for Wanda to create an escape from trauma into that fantasy world in a denial phase of grief. And to have trapped some bystanders in there with her. Next sit com episodes might show her working through that grief symbolically. And the consequences of what she has done to the multiverse which sets up the next movie and new superheroes as well.
But current canon allows anything to happen and IMHO that is not a good thing.
