Mo is her cousin, and I feel like they probably could get on like a house on fire. lmao. They both had a transition from sort of bubbly to sarcastic and edgy, so maybe they're somewhat close??
Lyllia is a neighbor of sorts! She's friends with Chesa, so she'd be nice to Halie, even if Halie is lukewarm in return.
I think she shared some years at Athena with Zoya, but Zoya was older. She would still be nice if she saw her around.
Jeb just started dating Chesa, though they've been flirting for a while. So there's that, too.
