YOUR FACE IS MY FACE
BASICALLY Rogue is from our universe and so is Molly.
AU Magneto (may or may not be the same as Uncle Pete, can't tell yet) is from a different world than AU Mom.
AU Mom seems to be from the same world as like, Falcon, Captain America, Black Widow, and Doctor Strange. Where we definitely don't exist. Yet? No one has said anything about Vision, so I'm not sure. Mom definitely didn't have Thomas and William, but I'm not sure if you and I exist in that 'verse yet.
