(Also based on personal experience) trans!Eddie is terrified to use the boys bathroom but the idea of using the girls bathroom makes him want to die and when Richie figures this out he always makes excuses to go to the bathroom with Eddie to comfort him and keep him safe and he will physically fight anyone who protests. He doesn't have a lot of muscle so he doesn't always win these fights but damnit that's not gonna stop him from protecting his boy
im squealing this is super freakin cute
most of the time nobody will be in the boys bathroom anyway, and if there is, nobody questions it. but richie will keep his arm around eddie just in case! eddie feels way more comfortable with richie in the bathroom anyway. if anyone’s got anything to say, richie’s there with fighting words and fists ready to fight (even if he ends up getting bruised a little himself, which eddie doesn’t appreciate too much.) either way, he loves the support richie gives him.
