Okay, I got to thinking (dangerous! lol)... What if Dean and Castiel's roles in SPN were reversed? As in... Sam and Castiel are brothers (or even just BFFs) who hunt demons and Dean is the angel who pulls Castiel from Hell. And they still have the same personalities we know and love (Cas= awkward. Dean=Dean, lol)

Are there any stories like that, with a Dean/Cas pairing preferably. Especially if it takes an episode and uses this twist. I mean, can you picture how some episodes might have gone if that were the case? Would "The Rapture" have been as intrigiung and sad? How about "The End"... would future!Castiel made the same decisions that future!Dean did? How would Castile have reacted to Sam's relationship with Ruby?

Thanks in advance!
