trainingverse prompts?

anybody got anything specific they want to see in the Trainingverse? I'm particularly looking for ideas for when the kids are young. Dean, Sam, Eliza or Dean's son Caleb, who I have yet to molest, haha.

I know someone wanted to see Mary playing with young kids, but I don't have any specific inspiration by myself at the moment, so that's one thing to think about, but any permutation of bodies is up for grabs, really.
