Honored that you would ask my humble opinion on this, so of course I had to overthink it! Here we go:

Charlie Bone: I was originally gonna say something basic like chocolate, but considering that sandwich abominations I was recently informed of - he'd probably like peanut, or maybe caramel or that blue flavour

Benjamin Brown: actually the one who eats basic flavours. Do I see him eating vanilla? Not really. But chocolate, dark chocolate or hazelnut (perhaps whichever one looks most like Runner)

Emma Tolly: I think she would have a reasonable taste, maybe stracciatella or strawberry. wonder if she felt the need to try out every flavour after awakening for her trance to find her actual favourite flavour and to know how getting ice cream with someone who loves you feels like

Olivia Vertigo: She probably DOES get a new flavour every time, and is disappointed when the shop doesn't offer anything she's tried before. probably eats these coffee and yogurt flavour ice creams that I would never dare try

Fidelio Gunn: Lemon. I don't take suggestions

Billy Raven: has this boy ever had ice cream in his life? Cook might've given him some, maybe neapolitan. But his own preferred choices would be: Cookies when he has one for the first time after leaving Bloor's, later Blueberry

Bindi Loom: idk if it's a thing outside of Germany but Waldmeister? "woodruff"?? anyways that or vanilla

Gabriel Silk: Banana. Just based on vibes

No idea. We were given absolute zero to go off of, so anything could have happened to them.

It's possible Beth went back to the circus and Bindi found a better endowed school? It's possible Bindi went to live with her grandparents and Beth found a better school. Maybe both of them gave up on endowed schools, maybe they transferred to one together.

Dorcas and Bindi have the same last name so maybe they're related, or maybe it's a coincidence. Dorcas never mentions Bindi and nobody ever asks her. If they are related, I'd like to think that Dorcas being evil and Bindi being good sparks a new generation of family rivalry within the Looms, like the Yewbeams except they aren't siblings.

Maybe Beth and Bindi would go back to Bone Academy one day, but I doubt it.

I guess the endings I personally like best for them is Beth joins the circus and Bindi transfers to another school, preferably one that also has a good drama class.

A circus made of the endowed is an interesting concept, if I ever make Charlie Bone ocs again I might go that direction.

As for Bindi, she doesn't have a special backstory aside from "grandparents live in India" so sending her anywhere but to another school would feel like I'm just making it up. But we know she was in drama so that's something. It could be a Charlie situation where she wasn't talented but had to go somewhere, but I think it would make her more interesting and well-rounded if she did have an interest or talent for something Drama-related: if not an actress, then maybe a screenwriter or director? She has those vibes, I guess? Maybe the glasses just make me think nerd lmao

god i love the perchance incorrect quote generator (more under the cut)
