Ok, so you know how some stories have a descendant from the future show up?
What if that descendant was from another universe?
In other words, maybe Lois and Clark meet the son of Louis and Claire. Maybe the child of Lois and Lex, or Clark and Cat, has to figure out why their parent is suddenly with someone else.
If you're not up for a full fic, feel free to spitball here. Who would meet whom, and how awkward would it be?
