hi jordan! i think bianca and avery would get along swimmingly! she definitely sought out all the ribbonfins to befriend when she arrived her freshman year, and she'd also never judge her for being trans if she were to ever find out.
aww, poor isabelle. i think bianca would have been super worried about her and wondered if she was ok until they were reunited at gooseberry. bianca would definitely make a point to run up to her, 100% unbothered by her breakdown and just happy to see that she's ok.
