his fam are pretty wealthy from london, sort of like topshop/asos money from their dad's business. they had an older sister who was a sort of d-list it-girl in the early aughts who passed away from an overdose, she would have been maybe 22 at the time ('05) but i'm happy to be flexible on dates and anything like that. he also has partied a lot through his life but managed not to let it derail his career or well-being or anything. but i kind of pictured he and his little sister being really close, obviously shared trauma but also they could either have the social aspect of their lives in common or he's creative so that could be the through line depending on what you wanted to do with her! but basically the family has money, is based in london, he's 36 so i feel like as long as she's 26+ she'd have been old enough that their sister's death impacted her in a meaningful way? but again flexible with the dates! and no pressure if not
