YES. Then Chuck/God saves both Sam and Dean from the cage because, IDK, they martyred themselves with no contractual obligations to Hell but aren't dead, so no free ride to Heaven, just back to Earth. (Using the idea that martyr automatically = Heaven a la the movie Constantine.) Sam insists Dean go place house with LIsa, but Dean's like, "Bitch, get in the car," and they go off and keep hunting, the end.

...and then eventually become gods of hunters (a la American Gods) because I'm obsessed with that idea. :p
