Adding on to what the Draco/Derek player said above, if she's one of his siblings then Foggy will be her cousin. Two relatives for the price of one, what do you say?

Foggy totally is into geeky stuff like Star Wars and anime. She might see him as a boring adult anyway but he'd attempt to be friendly and chat with her about their common interests if it comes up. He's also a teacher at the local high school. If they end up as relatives he would likely not be allowed to be her actual teacher but either way he is around if she needs an adult for some reason.
