“The Demon of the Road” (season 3, episode 4)
While Leland schemes to force Sister Andrea—who’s so close to God she sees angels and demons on a regular basis, an ability that’s also emerging in David—into retirement, the demonic-sigil storyline makes a key advancement. A long-haul trucker’s reports of strange occurrences leads the assessors to the culprit: a man in league with the 60 who’s using drones and freaky radio transmissions to perpetuate online tales of a haunted “Ghost Highway.”
But the case doesn’t end there. David’s Entity contact, LeConte—who brings a bit of X-Files conspiracy flair to everything—materializes to tell him he’s helped “eliminate a demonic family” because the drone operator apparently committed suicide (or was more likely murdered) after the assessors uncovered his operation. David realizes the Entity’s whole deal is holy war: their goal is to wipe out all the demonic families, in order to achieve, as LeConte wryly puts it, “peace on Earth.”
