Revenge of The Fallen (Crossover)
14 parts Complete "Hello, is this Dean Winchester? My name is Pete Wentz, and this is going to sound crazy, but I think my friend is possessed..."
Patrick Stump has been missing for a week. Pete is paranoid and depressed. In one last desperate attempt to get his friend back, he turns to the last resource he has: Sam and Dean Winchester.
At first, they're not too excited about it, with them having to prevent the 'breaking of the 66 seals' and all. But they start to gain interest when Pete tells them Patrick's begun to have yellow eyes. Is Patrick possessed by the same demon that killed Sam and Dean's family? Who would do this to him, and why? But more importantly, can he be saved?
