Art comes back from leave to take over Marshal operations in Kentucky. Vasquez questions Raylan and his relationship with Ava, whom he allowed to escape with the money, suggesting they are in cahoots. Later, after Raylan fails to heed instructions to return to Lexington, Art says he'll be coming to bring Raylan in himself. Boyd has been patched up and Raylan offers him opportunity to give up Ava before Avery and Katherine find her, but Boyd is intent on finding her himself. Boyd does suggest that Ava may be getting help from Zachariah, who helps Ava drag the money up to an abandoned mining rescue supply station in the hills. They've already left when the Marshals arrive, hiking to meet Groobes who can lead them across the mountains. However, they arrive to find the hermit long dead. Katherine responds to Mikey's call, but as she talks to Wynn about protecting and avenging ones partner, Mikey realizes there are other codes to follow and has a change of heart. Mikey takes five bullets but still manages to kill Katherine with his bare hands, passing Wynn the handcuff keys and asking Wynn to hold him as he collapses and dies. Avery pays-off the jail guards to visit Carl and Earl, arranging Carl's release on a mission to kill Boyd under threat of Earl's life. One of Avery's crooked cops gets Carl into Boyd's hospital room where Carl interrogates Boyd with a gun to his head, but becomes convinced Boyd is his best chance of saving his brother and getting out clear. After getting uncuffed from his hospital bed and into the lawman's uniform, Boyd shoots Carl dead to cause a diversion and escape. Learning that Carl failed, Avery gets Earl released as well but Raylan arrives in time to thwart the crooked cops. Raylan drives Earl to the Pizza Portal and threatens Avery's testimony in Carl's death for Avery to abandon any further efforts to reclaim the money or harm Ava, while also encouraging Earl to agree to testify that he might benefit from protective custody. Earl tells Raylan about Groobes, and Raylan heads into the hills leaving the Marshals to pick up Earl. Boon continues to threaten and intimidate Loretta.
