Leslie and Justin meet Frank, a strange and depressed man that has constant panic attacks. Leslie begins to have doubts about bringing him to her mother and tries to call it off, but Justin insists that they should "let this unfold". At the dance, where Andy's (Chris Pratt) band Mouse Rat is playing, Frank meets up with Marlene, who is repulsed by Frank's past, current unemployment and overall failure at life. She turns down his offer at a second chance at love, prompting him to storm onto the stage and denounce her over the microphone. Leslie apologizes to her mother for bringing Frank. She is later upset with Justin, but has trouble pinpointing the reasons for her dissatisfaction. Ron (Nick Offerman) explains that Justin is a "tourist," meaning that he takes "vacations in people's lives" and only cares about telling interesting stories to impress other people, which makes him selfish. Two older women then recognize Ron as jazz saxophonist Duke Silver, but he denies it. Leslie later breaks up with Justin, which Tom (Aziz Ansari) takes especially hard, reacting as if his parents were getting divorced.
