Plot summary
Raylan visits Winona and finds Augustine's men demanding he take them to Thompson. He kills them and, despite Art's warnings that he will be fired if he goes after Augustine, forces Boyd to arrange a meeting, where he tries to convince Augustine to turn himself in. He refuses and declares intent to kill Sammy Tonin and become Theo's successor. Raylan greets an arriving Sammy, having called him ahead of time, and allows Picker and his men to kill Augustine. The police find Delroy's body after receiving a tip, so Boyd waives the debt of Clover Hiller and funeral home director Lee Paxton so he can steal the body.
Ava goes alone to dispose of it, only to be arrested by new sheriff Nick Mooney, the entire thing having been a setup by Paxton after the police were tipped by Cassie. Theo retires and Sammy takes over, who puts Duffy in charge of the region's operations. Duffy asks Boyd to distribute heroin in Harlan. Raylan repairs the hole in Arlo's wall as Art calls him to reveal Augustine's death, in which he does not admit any part.
