Raylan's step-mother and aunt, Helen, calls him to tell him Arlo is in jail. Raylan reluctantly goes to Harlan, where Helen tells Raylan he needs to bail out his father. Raylan is wary about getting too involved with his father, who made Raylan live in fear growing up and who was constantly involved in some sort of scheme. Arlo in part blames his behavior on his own father, a religious man who mistreated him. Raylan eventually discovers that Arlo planned to use his own son as a shield from Oxycontin ("hillbilly heroin") runners, whom Arlo had stolen from. Arlo's plan works, as Raylan finds Oxy at the drug runners' house (planted by Helen) and threatens the Oxy runners with jail if he goes after Helen and Arlo again. Raylan doesn't even bother asking Arlo where the stolen Oxy or money is because he knows Arlo will not tell him.

Complete story — includes the ending
Raylan infiltrates the home of a fugitive by posing as a landscaper, having a tense moment with the man's wife but convincing her to stand down. Raylan's criminal father Arlo vandalizes the home of debtor Stan Perkins, who sends his nephews to take back property Arlo stole, injuring Raylan's aunt and stepmother Helen in the process. Arlo has a heart attack while beating the nephews, forcing Raylan to step in. He learns from Boyd's cousin Johnny that Perkins is a drug smuggler, and is warned that Boyd's father Bo is being released from prison soon and will want revenge on Ava for Bowman. Raylan finds drugs in Perkins's house, but realizes that Arlo set them both up by stealing Perkins's drugs and planting some to get him arrested. He confronts Arlo, who refuses to tell the truth, and promises to put him in jail after realizing Helen planted the drugs and lied to him.
