Remus loved dinosaurs. He learned about them in muggle school and has since been obsessed.
He told sirius and regulus but they didn’t understand the hype.
Peter let him info dump to him but never reciprocated his enthusiasm for them.
Mary and Lily also grew up knowing about dinosaurs but they cared more about the prehistoric animals.
Remus tried explaining dinosaurs to Marlene but she just wanted to her more about the meteor that killed them.
But James, James was ecstatic to learn about dinosaurs. He wanted to learn everything about them. James read books and learned every obscure fact he could find and he would always tell Remus everything he learned. James would enthusiastically listen to Remus’ info dumps and bring up his own points. The two of them could go on talking about dinos for hours. Finally Remus found someone to share his hobbies with. Someone who didn’t judge him and shared his enthusiasm.
Remus and James were bestfriends, they were major nerds and their friendship deserves more representation.
