Sorry I was away for all the conversating, was upstate. Here are some Cecil relationship ideas.

Cecil/Debra: Justice buddies. Whereas Debra is the straight-and-narrow Luke Skywalker in terms of morality, Cecil is Han Solo; Ultimately both good, but with different, sometimes clashing personalities. Debra seems pretty fair and honorable, whereas Cecil is willing to employ dirty tricks or venture into moral gray areas. If Debra becomes the leader, Cecil would be the lancer.

Cecil/Noah: Noah and Cecil are so different that I'd expect they'd start off not caring for the other, and perhaps gradually warm up with some sort of "We're not so different" moment. Your call.

Cecil/Carole: Also probably not friends. The only thing they seem to share is being from the south and knowing knotwork, and historically the valley girl and poor kid have either loved or hated each other. Maybe they started getting along after some shared kid-hardship like escaping detention or something.

Cecil/Felicity: Alright, I'll bite -- I have no idea why you gave your character the name Felicity. Is he supposed to be trans? Is there some A-Boy-Named-Sue shit going on? Does he get bullied for having a strictly feminine name? Cecil would probably constantly make fun of Felicity for having a girl's name, and that's about it. He's not that complicated in his teasing.

Cecil/Daniel: Probably friends. Cecil, who doesn't know when to shut up himself, would be one of the few people to not tell Danny to shut up when he gets rolling. They share lots of crass jokes about buttholes. 

Cecil/Phoebe: I assume Phoebe would dislike Cecil because he's a dick and she's a nerd. If racism is a thing in St. Stephens, Cecil being an undercover quadroon might come into play for their budding friendship, what with some Cajuns already occupying a weird racial grey area.

Cecil/Eliza: One of the few people Cecil doesn't tease too hard because of her fragile nature. Bullies tend to avoid kids who cry a lot because they attract adult attention, which seems like it'd apply here. Maybe Cecil, being superstitious and into occult-y supernatural stuff, believes Eliza more than the others about her supposed magical encounters?

Cecil/Emily: I can totally see Emily having a crush on Cecil, go for it. I don't think it'd be reciprocated, or at least not for a while, because Cecil's kind of ignorant to the nuances of communication like flirting. He probably just thinks she just laughs a lot.
