Roy helps Gator conceal the murder of his partner by arranging to make the death look like a road accident. At his ranch, Roy meets his wife Karen and her father Odin, a militia leader involved in Roy's weapons dealings. Dot prepares for another attack by changing the street signs around her neighborhood. She and Wayne visit a gun shop, where her confidence handling weapons surprises him. A waiting period prevents them from taking firearms home immediately, so Dot buys protective equipment and pepper spray. She plans Halloween costumes that allow her and Scotty to carry their homemade weapons outside.
Witt catches Gator taking material from the gas-station evidence and begins checking his background. Indira and her captain ask Lorraine to cooperate, but Lorraine wants the kidnapping investigation dropped and orders Danish to arrange security. Munch moves into an elderly woman's house without permission. A flashback to Wales shows a man with his face eating food over a corpse in a ritual that transfers the dead man's sins to him. Roy sends Gator's masked team after Dot on Halloween, but the altered signs delay them. Dot spots their van when her family returns home. Elsewhere, Munch covers himself in goat's blood during a ritual and enters Roy's house unnoticed.
