She's Vic's age, so she'll know him, she went to school with Eve for a year, she probably knows Charlie at least in passing, and she's Ash's cousin, so yay!
She probably knows Caylie, too - Caylie and Kareem dated for a couple of years, and Caylie's mom was in Dust and Icarus' class. I think the only ones who're probably unfamiliar with her are Alex, Amani, and Dean.
Ash is obvs gonna be the most excited to see her. It's funny she's popping up when he's not himself. XD Maybe they should have a chat in her new infirmary?
