Mina would get along with everyone, including Rhotahr. Rhotahr wouldn't get along with anybody, including Mina. Does that make any sense? Don't worry about it. +

Maisie is shy and quiet, and would probably vibe well with Jocelyn and Kara, but I think she'd be most interested in talking to Svana, as Svana is the other primarily-a-magic-user in the group. Rhotahr is decent with arcanima, too, but Maisie would be terrified of her. +
