The Devil You Know is the twentieth episode of Supernatural's fifth season. The episode follows Sam and Dean as they team up with a demon named Crowley to find the final two of the 66 seals in order to prevent the Apocalypse from occurring. The stakes are high as both sides struggle to come out on top, and the tension builds throughout the episode as they race to find the crucial seals.
