Sam’s jeans start to fit a little tighter

High-school AU, in which Sam and Dean don't know each other. But, of course, not everything is what it seems.

Dean flashes his best -- and most insincere -- smile at the properties officer as he signs his name and picks up his wallet, his necklace, his ring and watch, and the change he had in his pocket. The officer, a big, burly man with short-cropped grizzled gray hair doesn't smile back and isn't impressed or taken in.

CROSSOVER! Our two favorite pairs of vigilante brothers meet by chance, when rumors of a violent demon bring Sam and Dean to South Boston.

Sam and Dean go to Hogwarts.

Sam is trying to become the Antichrist in order to save the world. He has a small army of angels and demons, he has an adoring cult, he has a work of prophecy by Jack Kerouac, and he has Dean. Things are going pretty well until he accidentally signs Dean up as his Beloved Consort, a role that requires sex with the Antichrist on an altar. And that's when things stop going pretty well. Also, the soundtrack to the Apocalypse sucks.

When Sam steps in to rescue a boy and the boy's best friend from Green Bank Regional High School's biggest bullies, he expects trouble. What he doesn't expect is the trouble he gets. Sam is sixteen and keeping all kinds of secrets from Dean--about the boy he kind of likes and the supernatural situation he's found himself in. These secrets start to take their toll at home, where Dean is harboring his own secret, one that might be the most life-changing of all.

Dean and Sam are on the trail of a demon who is killing families that share a certain secret. When they run into another set of brothers working the same case, they realize all four of them might be in danger as well.
