- Leslie: Ron Swanson, this is an intervention. You have been spending the last 24 hours sipping on joy juice and tripping on Tammy. Well, the people in this room are your methadone. And we are here to get you clean.
Ron receives a note from a collection agency regarding an overdue library book. He finds it amusing because he knows it's from his ex-wife Tammy. He and Leslie visit Tammy, who tries to seduce him but he can resist her this time because he's in a solid relationship with Wendy, which Tom is still upset over.
The Parks Department is throwing a pizza party for the police department because they need to ask for police volunteers to provide security for the Harvest Festival. At the planning meeting, Ben suggests calzones but this is rejected by everyone else.
April is temporarily working as Chris' assistant and his usual cheerful, upbeat personality is driving April crazy.
Ron and Wendy have lunch together. She informs him that she has to go back to Canada to help out her elderly parents. She invites him to move to Canada with her, but he declines. They break up amicably.
At the pizza party, Leslie and Ben discuss the strategy of when to ask Chief Trumple for the favor. Leslie consoles Ron when he tells her Wendy's moving away. When Leslie and Ben talk to the chief, Ben behaves awkwardly due to his fear of cops, so Leslie drags him away before asking for the favor.
Ann's enjoying her time with Chris, and she's even taking the health supplements that he suggests. Since he's moving back to Indianapolis soon, she wonders where their relationship is going.
Tom shows up at the pizza party with Tammy, who keeps calling him "Glen". They try to make Ron jealous, but Ron tries to warn Tom not to get involved with Tammy. Ron and Tammy start fighting but are stopped by the police. Leslie tells Tom about Wendy moving back to Canada, but she freaks out when she finds out that Ron and Tammy are going out for coffee.
Hours later, Ron and Tammy are in jail, passionately making out with each other through the prison bars, and Leslie and Ben have come to see him. Ron and Tammy have gotten married (again). Leslie convinces the police to let Ron out.
Chris asks April to call Ann to cancel their lunch date, but April only pretends to do so. When Ann comes by to find out why he stood her up, she sees April and understands immediately what happened. April hopes Ann will tell Chris so he'll fire her, but instead, Ann tells Chris that April was very apologetic and even sent flowers on Chris' behalf.
Leslie and the Parks staff hold an intervention for Ron, though Jerry thinks it's a reception so he brings a gift. Tom, still mad at Ron, encourages him instead. Andy doesn't have much to contribute, and Donna yells at Ron. Even a pre-recorded video of himself fails to convince Ron to dump Tammy. Tammy shows up and they start making out. Everyone else runs from the room in disgust. Later, Leslie scolds Tom for bringing Tammy back into Ron's life.
Andy shows up at Chris' office with a note that is ostensibly from Ron, asking for April to come back to the Parks department. Chris tells April he understands if she doesn't want to work for him, but he thinks she's smart and he wants her to come to Indianapolis to be his assistant. Ann, who hasn't received any hint from Chris about her status with him, is shocked. When April says she'll think about the job, Andy is bummed out.
Ben approaches Chief Trumple to ask for the police department's help during the Harvest Festival. Chief Trumple agrees immediately, explaining that Leslie gets any favor she needs because she uses favors to help other people. He also notes she also made Dave less cranky when she was dating him. Ben is curious about Leslie and Dave, but the chief thinks he's weird for asking about them.
Ron and Tammy are having a bridal shower at the library. Tom shows up to tell Ron that Tammy only wants to make Ron miserable. Tammy starts beating Tom up, and this finally brings Ron back to earth. After calling Tammy out for the monster that she is, Ron leaves and carries Tom out of the library. The two make amends and share a glass of scotch together.
Tropes
- Accidental Misnaming: Tammy keeps calling Tom "Glen".
- All for Nothing: Tom and Wendy's marriage proves to be this in this episode. Tom married Wendy to help her stay in the US, then realized he genuinely liked her right as they divorced, but she didn't see him as anything else beyond a friend, and she moves back to Canada to look after her ailing parents. Ultimately, they spent three years married to each other without either of them getting what they initially desired.
- Bridal Carry: Ron rescues Tom from Tammy beating him up and carries him out of the library like this.
- Call-Back: Leslie and Dave's relationship is referenced by Chief Trumple.
- Comically Missing the Point: Jerry does not seem to see that Ron and Tammy are horrible. He even bought them a wedding present!
- Curb-Stomp Battle: Tammy easily beats Tom in a physical fight. Seeing this is what snaps Ron out of her spell.
- Eagleland: Ron laughs at Wendy's suggestion that he move to Canada with her.
- Everyone Has Standards: The librarians are fully supportive of Tammy Two's various antics to mess with Ron and make him suffer, but when she starts throwing Tom around and hitting him, they seem genuinely shocked.

- The Maiden Name Debate: Parodied among Tammy Two and her friends. When she and Ron get married again, one of the other librarians gives her a gag gift of a library card reading "Tammy Swanson-Swanson".
