I'm really worried about Christopher and Nate, personally. If the other Lois and Clark are in THEIR universe, then Christopher, at least will notice their not his parents. Nate may notice as well.
Christopher is at the age where kids often get upset when Mom and Dad leave to go out for the night. How is he going to feel when the people caring for him are NOT his parents and he doensn't know where they are?
I can easily picture him crying his eyes out for Mom and Dad. Nate may pick up on Christopher's distress as well.
