Well, she's adorable.

So Jemima is a few years younger but if Victoria could put up with her ~whole vibe, Jemima would really love her as an honorary older sister type? Even if not, Jemima also very much has a sweet tooth and is a similar foodie so would come by a lot and you can probably tell exactly when she's in a good mood vs trying to drown her sorrows by what she eats there, lol.

That is probably my best bet, but I also have: Theo, who was in her year and a fellow prefect, and much more outgoing/ friendly back at school; Bram who lives at the Sanditon; Elias who is semi-hurlable; London-based customers in Savino (who would be friendly!) and Estelle (who would be very rude), or anything else you can think of. xD
