savannah will be excited about more businesses coming to austin, even though the doughnut hole isn't in her district. she'll definitely visit! i can't see why they wouldnt get along, and sav's probably the only one of mine who might slightly recognize her name in relation to her olympic diving?
marina likes donuts though might find her eternal optimism annoying but she also appreciates sass so we'll have to see how these two do together lol. marina will also be getting her GED so though shelby (i assume) will be doing college courses, they might cross paths in the school setting.
isaac loves donuts! they have a very ~sentimental~ place in his relationship with demi so i'm sure they will go there together some time? other than that, i'm not sure how they'll get along or what they might have in common but i'm open to throwing them together!
i think of all of mine, bea will get along with her best. i don't think she'll know her from the olympics but they both were super into a sport (shelby with diving and bea with her trapeze stuff) so i could see them bonding over that! bea will also probably be taking some college courses for her medical assistant work, so they could cross paths there.
mina is much more reserved so she might be a little thrown off by shelby's personality, but they'd probably get along?
