Dead Beat (Deastiel)

It's been weeks, maybe months since the last outbreak, it was only a level two, but it was pretty bad. Cas almost lost Clare, his sister, God knows she's not gonna be let out of his sight for however long. They come across and old jeep with a full tank, and decide to take a road trip... To think only months ago they were high school kids, but now they're running for their lives.
They go back to their hometown, to an old quiet, landlocked town in Kansas for a break. That's when Cas meet Dean Winchester, his crush from middle school, and the man who saved his life from the apocalypse.
