All Along the Watchtower

All Along the Watchtower - leonidaslion Read this in one sitting, another excellent fanfic from leonidaslion. She has Dean's character and voice down to perfection. In this story, Sam and Dean perform a ritual to rid the world of demons and angels. They end up wandering through a near deserted post-apocalyptic America.

'The ritual worked--Dean knows it did, no matter what Sam says - only he thinks now that maybe it was already too late. Maybe it was long past time to save anything at all.
"This is the way the world ends," Dean thinks, and closes his eyes.'
