Zooey: Charlie probably hates her. She's three years younger, but if she knows her/knows of her, she hates her. ;x Finn probably wouldn't have any association with her? And Jonathan's a noob.
Noah: Finn is actually quite like him, but I don't think they'd have any contact? Charlie breaks shit all the time so she's probably constantly banging at his door like "Uh. Hi. Yes help please." and Jonathan is new, but he's super friendly and personable and would probably talk his ear off if they crossed paths. Just like "Wow, you know about computer? You must be like really smart. Computers are complicated. Rabble rabble rabble."
Miles: Might know Finn because they both work at the school? Finn would be torn between liking him and thinking he's way too much. He's grumpygills. Jonathan is one of his new students and he already loves him. Fact. And Charlie probably thinks he's fucking awesome too even though he's not her teacher anymore.
Honey: Charlie is in her year and probably finds her perkiness grating. We're sorry, Honey! Charlie probably bounces back and forth between being civil towards her and being downright rude. Jonathan is a noob, but if they crossed paths they'd probably get along really well! And Finn probably doesn't know her.
Alba: Jonathan is a first year with her and their older siblings are dating soooo clearly they need to be super awesome friends. She could actually probably help him a lot because he has a really difficult time being open about anything, so she could maybe help to encourage him to do that? Finn is one of her TA's and probably appreciates her calm demeanor. Wild students go away. Charlie has no idea who she is?
