Avery will get along great with Elle, I think. She definitely made an effort to make good impressions on all of Liam's female friends after they started dating.
She'll love Kai and will talk nature/animals with him whenever she pops in at the clinic or sees him around.
Sarah. ♥ Avery tries to showcase local talent whenever possible, so she'd love helping Sarah showcase her work in the gallery. And maybe she organizes nights where Sarah's students can do the same.
