if cross is in your utmv, how do the events of underverse/xtale play out so they don’t interfere with your whole plot?
It will still be the same story
The story of killer can work out with or without the other multiverses
Example
The story of the “unrelated the omen wings”
It can be after killer was about to erase himself but decided not to and make a change to fix his universe
it can be after nightmare saved killer from erasing himself then the underverse or any kind of multiverse story in between happened then him getting back to fix his universe
Both can exist in the same time
