She would definitely know Remi because she's good friends with Liam! I think Remi would be really fond of Avery and thinks she's adorable and sweet. So maybe they can be good friends, too?!
I'm pretty sure she needs to be friends with Dottie because they can be equally bubbly, though Dottie is usually a bit on the more socially awkward end of that scale. But she's very artsy since she's a fashion designer, so they have a lot in common that way!
Lyllianna should be super interesting because she's Lyanna from GOT and from what I remember Cersei basically hated her and the memory of her and her whole existence because she had everything Cersei wanted despite being dead, sooooo. lmao. I don't know if there might be strange, latent feelings there. We can figure things out!
Morrighan is super artsy as a tattoo artist, but she's also pretty stand-offish and abrasive.
Zoya probably comes to the art gallery! She works in a museum in D.C., so that's in the general vein of her interests. Avery also would have arrived in the period of time when she was gone from town and she's just now returning, so she would probably enjoy the fact that with her, she would have a clean slate.
