Sad to say I can't offer either of mine for Essie's drama (since Casper is mean and Cecil is gay), but still yay for new characters!

Cecil almost certainly treats Essie like a little sister, because she's a sophomore, an Azurcrest, and the lil' sis of a good friend. He's sad that she didn't go out for cheer this year and a little surprised by how much she's changed, but won't give her a hard time or press her about either, and is generally fond of her upbeat, imaginative self. He's also in Outdoor Exploration with her.

Casper probably gives Essie the eye-rolling that he gives pretty much all the happy-go-lucky types he doesn't understand, but likely doesn't have much issue with her. There's not much overlap between the two, apart from Dueling/Fencing, where he's more interested in the former and she's more interested in the latter. But I'm always up for random encounters if we ever want to try them~
