I feel like we always assume the marauders found out Remus is a werewolf because they’re clever–which, in part, yes–but remember that Remus Lupin nearly flings his briefcase across the room when Harry asks if he knew Sirius and he’s like NO WHY DO YOU ASK??? So, I think more realistically, 13 year old Remus was probably even a worse liar than 33 year old Remus and it’s a miracle the whole school didn’t find out
Reminder that when Remus was fifteen and in a crowded entrance hall, he said the equivalent of, “How to identify a werewolf? It is I. I am the werewolf.”
and when james said “haha i have a werewolf friend” he panicked and went “HOLY SHIT PRONGS SHUT THE FUCK UP PEOPLE COULD HEAR YOU”
