J. K. Rowling goes to Writer Hell and sits around a table drinking with Ian Fleming and Roald Dahl
The TV is constantly blaring in the background with, like, Steven Universe or something. It's a racially diverse, queer- and fat-positive show by a Jewish creator. The TV would piss off Dahl in particular on top of everything else.
Rowling would be trying to get Fleming and Dahl to respect her as One Of The Lads. Fleming would see her as, like, on the same level as some of the more educated Bond girls, but still fundamentally think of her as A Girl (and a not too bad looking one, especially if we go with the Return of the Jedi Special Edition rule that the afterlife de-ages you) and treat her accordingly. Fleming and Dahl were both womanizers themselves, not to mention spy buddies during World War II, so they'd probably end up fighting over Rowling.
They'd also get into an argument about
Israel (Dahl is anti Israel and uses that as an excuse to bash Jews, Rowling is pro Israel
and also hates Jews)who can come up with the most offensive character name
