Sirius being the first one Regulus comes out to as trans. “Sirius, I think you might have a brother not a sister.”
Regulus being the first one Sirius comes out to as gay. “Reggie, I think you might be getting a brother-in-law not a sister-in-law. If I can get away from our parents.”
“Sirius being the one Regulus confides in about his crush on James. “Sirius, I think I like someone…” “Oh? Who is it? I can help you with it.” “Sirius, it’s James…”
Regulus running away to James’s house shortly after Sirius does, because James will gladly take him in too.
Sirius being friends with the Skittles. Regulus watching on as his brother talks about star signs and crystals with Pandora, gives fashion advice to Dorcas, gossips with Barty and trades food with Evan.
Regulus being friends with the Marauders. Sirius watching on as his brother talks about their lessons with Moony, giggles in corners with Wormtail and is completely in love with Prongs, whether either of them knows it is a different question.
Sirius and Regulus being known as the hottest at Hogwarts. Remus and James hating that everyone thinks that because “Oh James what are the chances that he likes me back. I’m just me and EVERYONE LIKES HIM.” and “Oh Remus how can I compete with any of them. He’s so pretty and surely he can’t think I’m good enough for him.”
Sirius being the one Regulus confides in about his crush on James. “Sirius, I think I like someone…” “Oh? Who is it? I can help you with it.” “Sirius, it’s James…”

Regulus being so happy for his big brother when he starts dating Remus, and not just because that means he gets a built in study buddy.
Remus and Sirius conspiring to get James and Regulus together post-Hogwarts. They have had enough of the pining. They lock them in a room together whilst they’re drunk and hope it works itself out. It does.

Remus and James out one night drinking when they realise “What do we mean we got the hottest guys in school to fall in love with us?”
