NPCs
I know it's humorous, but she hasn't really done anything to join the club, as it were (i.e. report someone here in town for being supernatural or using magic), and I'm not sure that'd be as satisfying a scene as it might sound.
She'd be able to kick up a fuss, certainly, but she'd just be another Karen-in-the-wild. The police would have to placate her, but she's from out-of-town, so there would be no lasting consequences unless she assaulted someone. If she did, then our characters become the bad guys for doing something fae/were/magical/vampirical to her.
Just saying.
