Remus and Xeno would actually have been such good friends, their vibes compliment each other so well. Xeno being the only non-marauder who knew Remus' secret and his future-quibbler-publishing ass would have been so psyched to know a werewolf. Xeno naming Luna after the thing that made Remus so special. They would have stopped talking after Hogwarts bc they're both horrible at keeping in touch w people but they still think about each other all the time.
