Bash is a really good friend of Alex's, so they might sometimes see one another around because of that connection, and Zoya is Alex's little sister so same thing with that, if she ever drops by the architecture firm to see him!
Finnley would probably get along with her decently! She skipped two full grades and graduated Athena in 2008 as a result, so they were kind of in the same boat-ish, but with Finnley being a tad older. Maybe in school they were made aware of each other?
I also have Lyllia, Rhys' wife, and obviously that relationship is going to be tense and Not Good because of the family history there. But she pretty much tries not to stir the pot and will leave Manda alone so long as Manda leaves her alone, though she is not one to let herself be walked all over by any means. She's also Very Pregnant right now. lol.
I'm down for figuring out other connections, too, but those were the obvious ones! :D
