When the pair leave the house together, however, Strudwick is suspicious and confronts Dick. Mrs. Dubcek suggests that they could have eloped, so Dick and Strudwick rush off to track them down before there's a baby on the scene, managing to accidentally abandon Mary in the process. Meanwhile, Tommy has rented a scary movie to watch with Alissa, in the hope that it might bring her into his arms, but Sally and Harry decide to show up and make it more real.
Dick takes Mary up to his penthouse and wines and dines her, but she tells him that she doesn't believe in true love anymore, no matter how hard he might try to persuade her otherwise. Meanwhile, Sally isn't happy being second fiddle to Don's wife so she asks him to break up with her. Don, however, wants to run for president and so refuses, so Sally breaks up with him; while at NBC, Tommy's huge ego and demand for a high pay on Saturday Night Live leads Harry to fire him.
Mary is having trouble dealing with what she has just seen - Dick transforming Liam into a monkey, which he had done to stop him doing the same to the Earth's population. Dick consults the other Solomons and they decide that the best approach is to deny everything. Meanwhile, Mary meets with Nina and Judith, who confess that they believe Dick to be an international terrorist, so when Dick and Mary next meet, she demands that he tell her the truth about himself. So, Dick tells Mary that he and the others are aliens. Mary's reaction is first disbelief, then shock, and then she finds it sexy to be dating a spaceman. Elsewhere, the local store has been robbed and Sally catches Don hiding in the frozen foods freezer, where he admits that he hid because he was scared. Harry takes a different line and asks the shopkeeper Sam out on a date, but later runs into her working at a posh restaurant, where she instructs him to call her Samantha. Confused, Harry believes that he is dating twins.
