S1, E7: As their clandestine affair progresses, Dave begins to learn some of the details about Lisa's former boyfriend, Stewart. Aware of just how much Stewart was liked by the station's staff, Dave then finds himself facing a problem of his own -- the unexpected arrival of his former girlfriend, Nancy. Meanwhile, over Lisa's objections, Dave chooses Bill to interview a business visionary who has made a real impression on Jimmy. However, when Bill makes himself the center of attention, Tom Baxter walks out of the interview without saying a word. It's only when Nancy arrives that Lisa learns that Dave never really broke up with her before leaving Wisconsin to take his new job in New York. In his own defense, Dave explains that he didn't call off the relationship for fear of hurting Nancy's feelings. Though Dave insists that she's fragile and needs to be handled with care, Lisa learns otherwise when Nancy warns her to stay away from her boyfriend -- or else! Meanwhile, after Baxter gets another chance at an interview, Bill refuses to say anything at all. Though Beth is sure that Lisa must be joking, she realizes just how serious it is when she, too, gets one of Nancy's stern warnings to keep away from Dave. After Dave finally sets her straight about his relationship with Lisa, he thinks he's gotten rid of Nancy once and for all. However, when Nancy arrives at the station to bid everyone farewell and tries to tell everyone of the affair between Lisa and Dave, the incredulous staff refuses to believe her. Finally, only after Catherine is finally given a chance to interview Tom does everyone realize just how shallow he really is.
