Trans!Andromeda and Trans!Regulus except they switch names after they both come out
“You ever see a guy that handsome walking down the street, he’s gonna get arrested. Cuz he’s killing all the ladies” but it’s Sirius encouraging trans Regulus when they’re young and he’s experimenting with boys clothing
Sirius being really worried that Regulus’s future boyfriend wouldn’t know how to handle him being trans and Regulus getting hurt, then Sirius being elated when he finds out James (HIS James) is Regulus’ boyfriend and sitting down with James to make sure he will treat Regulus right.
black siblings angst to me is sirius knowing she will never be loved by her parents like regulus is, is regulus knowing he will never be as talented and brilliant as sirius, is sirius being disgusted that regulus have the same beliefs as their family while regulus is disgusted that sirius had everything he wanted and she threw everything away, is sirius being able to express her gender as she please when she move on with her new family while regulus doesnt even dare to dream about telling someone he may not feel as a girl, is them fully embracing the hate for each other and yet a small part of them still miss the time where they were to young to hate and used to play together
Walburga didn't know anything about Regulus being trans until he came home with short hair at Christmas his first year at hogwarts. He got on the train as her daughter and got off it as her son. He cut his hair the second he was on that train and borrowed trousers from Sirius. Obviously Walburga wasn't happy but everyone already knew Regulus was a guy now so she had to play along with it. She never called him Regulus though, she never called him her son, to Walburga he was just trying to defy her.
Evan was the first one to find out Regulus was trans (apart from Sirius) because he accidentally walked in on him changing.
Evan: oh sorry- what's that??
Regulus: a binder
Evan: what's a binder
Regulus: it flattens your chest
Evan: why
Regulus: to hide your tits Ev
Evan: but you don't have tits you're a guy
Regulus: 🥹
He's confused but he's got the spirit!!
