In the first season finale, Harlan is turned into a battlefield when the tense situation between Raylan, Arlo, Boyd and Bo Crowder finally comes to a head. When Bo sadistically kills all of his son's followers, Boyd looks to Raylan for help. Arlo's plan to betray Raylan is found out, and he is shot by Raylan. Ava is kidnapped by Bo and Johnny Crowder, after which, Bo shoots Johnny for suspected collusion with Boyd. Boyd and Raylan go after Bo to rescue Ava. At the standoff, Bo is unexpectedly killed, in an ambush, by Miami gun runners who are after Raylan. Raylan and Boyd manage to save Ava and kill three of them, but one of them escapes. Raylan is forced to let Boyd (who calls Raylan his "only friend") chase after Bo's surviving killer.
