Team Raylan comes upon the Harris Brothers, who have previous knowledge of Agent Miller. The brothers tell Miller and Raylan that they haven't seen Hot Rod Dunham in awhile (since, you know, that time they pointed guns at him). Miller leaves the Other Dude to sit with the brothers while he and Raylan continue their search for the lost member of ZZ Top.
What follows is an unintentionally hilarious scene between two thugs and a DEA agent who's supremely unprepared. Be honest, you didn't expect this guy to last more than five minutes, did you? He's quickly knocked out, and we've got more bad guys on the loose.
Back at the bar, Boyd finds out what his mysterious mission is: to get revenge on the guy who murdered the prison nurse's previous partner in drug trafficking.
And speaking of killing people, Hot Rod Dunham stabs a dude with a pencil and frees himself from captivity, only to be bleeding to death a couple of feet away from a gunshot wound he suffered in the struggle. Raylan and Miller arrive just in time to find out what little he knows about Boyd, the Crowes, and the drugs. We're perhaps supposed to see a parallel forming between Raylan and Miller, and their shared tendency to color outside the lines, but it's not quite there yet.
Where's the dude that Boyd is supposed to kill? Dying slowly in a nursing home, and still bitter about how the drugs smuggled into the prison claimed the life of his girlfriend, who was behind bars doing time for check fraud. Boyd suggests that rather than killing him, he can spirit him off to someplace else.
Boyd has no idea that the Harris Brothers would like a word with him, and have turned up at the bar to get it. It ruins every episode of The Practice to see Steve Harris shove a gun into a guy's mouth. A guy that Raylan and Miller find tied up behind the bar sometime later. Miller is unconcerned, helping himself to the bottle of Maker's Mark left on the bar, while Raylan actually tries to do something useful.
Wynn Duffy has a business meeting with Boyd, the Crowes, and Picker, with Duffy sitting there looking as if he can't believe he's being subjected to this. He points out that the heroin hasn't even actually arrived yet, and doesn't want to make any deals until the product is present, because he's not stupid. Outside, the Harris brothers are announcing themselves, leading to way too many people in one room at the same time. Especially when Raylan and Miller show up.
After we learn that Raylan doesn't know a damn thing about the works of William Shakespeare, Miller declares his intent to arrest both the Harris Brothers. When Steve doesn't like that idea, Miller shoots him instead. Wood, on the other hand, wisely surrenders. Raylan decides he's had enough of Miller, and leaves him outside Audrey's, heading back to Lexington.
Things wrap up as Boyd has Jimmy strangle the dude he was supposed to kill after all, while Daryl discovers the money that Raylan left Kendal with and confronts Wendy about her loyalties. She announces her intention to leave, which is kind of like painting a target on your own back. And in prison, Ava finds out she's not getting out from under the prison nurse's thumb that easily, as now she's being asked to commit a murder of her own.
Then there's Raylan, whose not-vacation ends with him walking into the office and being snarked at by Art, who still doesn't like him very much. "You do whatever the hell you want, somehow it all works out, and I'm the dumbass losing sleep over it," Art rants, ignoring Raylan's plea to resolve their difficulties. Oh, snap.
And Miller crosses Danny and Dewey Crowe, leading to Dewey running over both his brother and the DEA agent, having lost what was left of his marbles.
