The girls need to go on a road trip, where, idk but the five of them and their gfs in an rv for a week would be funny
Do any of Hell's rings have forests?? I'm assuming not, so they'd probably have to go to Earth.
Carmilla's been working too much, Sera insists she needs to take a break, so Verosika or Kiki suggest an Earth vacation. Humans like to rent these gas-guzzling fossil fuel machines, drive out to the middle of nowhere, and "get back to nature", whatever the fuck that means. It'd be great!!!
It sounds miserable. Absolutely dreadful. There's no way Carmilla would agree to something like that. Not in a million years. But in the next scene, somehow the Carmines, their girlfriends, and maybe Vaggie and Charlie, for some reason, are all squeezed into a 40-foot luxury RV they rented from Wally Wackford (because he's selling those now, for some reason) and use Verosika's Asmodean crystal to travel to some bumfuck nowhere national park.
Any time they need to be near other people, they adopt the human disguises they had in the serious!crack/college AU. Velvette just doesn't bother, because that's so beneath her. She's having the worst time out of everyone else there. The mosquitos are eating her alive.
Various hijinks ensue of the fam just trying to take a nice, relaxing vacation in nature while also having to dodge humans and forest critters and almost getting caught in their demon forms constantly.
