#26 - Cooler Heads Will Prevail - in A Cabin In The Woods
He'll just, chill in there for the duration. Do vampires sleep in their c'offins in this comic? Some do-- but not all of them. It's usually solitary, newly made vampires; "spawns", who return to the grave to rest. If they are collected into a coven, the lead vampire will provide a dark place for them.
Yes, this is a "spontaneously burst into flames in the sun" sort of vampire comic, because I find that funny :D I'm typically a stickler for adhering to classic folklore and mythology as close as possible, but a few movie/pop culture tropes certainly are exceptions. While there are vampire myths about them fearing the sun, the catching on fire thing is a Hollywood invention. :)
