In which Sam and Dean start investigating something that Harry's also investigating, leading to working together to solve a case.
Bonus points if Thomas is hanging around for some reason (like setting it when's he's living with Harry?). Super bonus points hilarity points if at first Harry assumes Sam and Dean are a couple, and Sam and Dean assume Thomas and Harry are a couple.
Extra super-duper completely optional bonus points of doom if you give me some Thomas/Dean. (WHAT. IT WOULD BE PRETTY. Even if Harry would then have to restrain Sam from killing Thomas.)
Yet another Supernatural crossover
