I'll drop some:
>Victor
Some random loser kindred who dubbed himself the Prince of this shit-tier town that only has corn but got pushed off by someone else, who might be in charge of those vamps Tiara faced. That can mean anything, but there's definitely a more powerful entourage setting up shop in Mythton. Somehow he knows about the Hunter Cell operating in the city, and sounding acquainted with Totally Not J-Chad (assuming she's the leader instead of a recruiter), I have a feeling he cut a deal to get rid of whoever put him in this jam.
>Chad, Greg and the Brohood
Just formed their own Cell and would totally get wiped the fuck out if Yuul chose to follow them, but now there's a chance they can show up later acting in the background, or straight up becoming a gang of redshirts obliterated on campus. Since Chad and Greg are the only named ones, there's a chance one or both of them can be recruited later on. I'd personally love if Chad dropped the bad news to Yuul that everyone including Greg got mauled, gotta have that need for vengeance running hot in their blood.
>Dr Oopsie
By telling Yuul to grab the sticks and stones, the doctor is either a Loyalist colluding with The Hook, or trying to figure out how those would help in (unknowingly?) creating a Promethean. The sorority may also be involved in this mess, by orders from a different Fae.
