One Shot by trolllogicfics
Gen. Post Devil's Trap, Pre season two. Author's summary is There's a body in the back seat.
There’s about half a second of complete silence before the radio squawks on suddenly and Black Sabbath’s blaring out of the speakers. There’s an odd sort of static under the music. Your head snaps around to investigate, but your gaze snags on a figure in the passenger’s seat. Tallish, shaggy brown hair, he’s not transparent, but he’s flickering. He cocks an eyebrow at the radio. “You know, there’s EVP on that.”
