I feel like Remus would have a quiet, but hilarious (often morbid) sense of humor.
like, James and Sirius are in the forefront, wildly charming, but Peter would be hanging back with Remus, and he’d just drop these little bombs that are wildly funny or dark as hell, which would make Peter laugh way too hard.
And people around them would be, like, What? What’s so funny
And Peter just holds his hands up, like, No way. I’m not repeating that.
