sirius lowkey has a shit memory
like imagine, its post prank, sirius-angst, he's miserable, his friends arent talking to him, regulus doesnt know whats happening and is like -39% skilled at comforting ppl, so he's just petting his head like sirius is a toy cat and regulus is the toddler that was gifted him
anyway, in his misery, sirius claims that he's always been an awful person
and regulus, is like, 'wait are you supposed to let ppl talk or tell them theyre wrong, why isnt there a guide on how to comfort ppl' in his head
so sirius just keeps on rambling and rambling, and then he's like 'im also a shit brother'
and regulus is like 'shit now i have to say something' but before he can open his mouth, sirius is recounting the time he was super evil to regulus
sirius: you were like 6 and you were having a birthday party and we were in the black manor and everyone was there, and everything was so pretty, and they got you a really nice cake, and it was big and pretty and perfect, but (becuz im secretly evil) i got jealous at the attention that you were getting so i pushed it and it fell and they had to get a second store-bought one and i messed up your clothes and you had to change into the back up robes and i dont even know why i ruined it all, but i did
regulus, still awkwardly petting him: okay that's not how any of that happened
sirius: u dont have to spare my feelings
regulus: i dont think ive ever done that. but no seriou--that's not what happened. its true there was a big cake, made specifically for me, but it was pink and girly and i hated it, and i sat under one of the tables and cried, and you found me and next thing i knew you'd pushed the cake onto the floor
sirius: i dont remember that
regulus: and sure i wouldnt have cared now. but back then? i didnt have the words for it, i just knew i hated it when anyone called me that name or treated me like i was a girl, and wasnt like you. and i hated the robes too, disgustingly girly as they were. you got them so dirty, adn the guests were just about coming in, and uncle alphard swooped in before maman could do anything and said he'd take care of it, and i got to wear robes that matched yours and eat a cake that wasnt girly. and it was honestly a really good birthday, and it was because of you
