I’m still workshopping a lot of the details but I t h i n k that she and George didn’t meet until the 80s. So there’s about a hundred years of room for him to have met her on his own, when she was tooling around Europe, performing in cabarets, if he’d go to that kind of place either by himself or with others.
She’s free spirited and crass, asexual and aromantic despise her line of work (or perhaps because of it). Just a real strange hedonist with no regard for social mores.
