Abby: Dorian's a great innocent friend! They can innocent together! Damascus is NOT innocent! You cannot innocent with him! But you can innocent AT him and he can be an asshole? He could be her professor during the summer or fall semesters? Lia needs all the friends - she will be, I'm sure, my most active character because of her need to talk to all people. Two happy blondes hitting it off? Until Lia says something stupid? And Eli loves books - especially science books - so maybe Eirena takes him by the shop regularly?
David: DORIAN CAN TEACH HIM SIGN LANGUAGE. THEY CAN ASL AT EACH OTHER. Lia likes your dog and will probably try to walk off with it. Cuz she takes things she likes (ask Mo, the guest bedroom is FULL of stuff now - some of it not actually paid for, oops). Damascus and he might get into all the tiffs, which could be excellent? And Eirena is also open to be a friend or someone to bump into.
MISS HBIC: Dorian is perhaps mildly afraid of her. In that "yes, ma'am" kind of a way where he isn't so much afraid of HER as what badassness she wields. Eirena...it would be tricky. I could see them being alike enough that it works or that they bump heads repeatedly. Lia will ABSOLUTELY drive Val MAD. And Damascus is all "heeeey, i see you girl~ you look fresh to death".
