Tom's father, Rodney, a traveling salesman, comes to visit. When Lynette returns home unexpectedly, she stumbles in on Rodney making out with a mystery woman, whom he claims is just a client. Lynette takes a tough stance and throws Rodney out of the house. Tom comes home and says he's not all that surprised about the affair, and that he's actually kind of impressed that his dad is still getting it on. Which results in Tom sitting next to his father on the curb. That night, Lynette apologizes for overreacting but needs to be reassured that Tom would never cheat on her. He assures her he's not his father, but later admits to Rodney that he has committed an indiscretion of his own, one that Lynette can never know about.
