Dean and Cas are both stuck in Purgatory, and Dean can't survive long enough on his own. He needs to find a way out, and without the help of Cas, all seems hopeless. Dean finds someone who has a mysterious and unknown backstory, and he decides to put his hope in the fact that they can get him out, along with Castiel. THIS IS A PURGATORY AU. So, that means not everything will go as it did in the episodes. The only thing I own here is my O.C. and the idea. I apologize if anyone has already came up with this idea, (which they probably have) but I haven't read many fanfictions.
