AU crossover. Tony Stark has known Charles Xavier since Tony was eight and Xavier was his Uncle Charles. Now that Tony’s all grown up, Charles vets his dates. Well, most of them. Except for the ones where Charles brings someone who should really be in jail, not a fancy restaurant.
Slid off the back of this prompt in that it’s Charles who is Tony’s oldest friend, and Tony’s not much of a fan of Erik: By virtue of being Tony's oldest friends, Charles and Erik reserve the right to vet all his significant others. Through terrifying dinner parties. Even they can't find much wrong with Steve, though. And sort of end up asking why he's with Tony.
Thanks to Copperbadge and 51stcenturyfox for beta/Americanpick, and pointing out/fixing the bits that didn’t make sense, and to Copperbadge for providing a title.
