Roz tries to train the woefully incompetent Noel as Frasier's new producer as she prepares to leave KACL. She becomes increasingly melancholy about the possibility of leaving Frasier, and bristles upon learning of his new relationship with Julia. During a farewell dinner with her co-workers, Roz becomes concerned by the obvious closeness between Frasier and Julia. She suddenly announces that she is turning down the program director job and staying at KACL. At Cafe Nervosa, Julia tries to call Frasier's cell phone while he is in the restroom. Roz sees that she is the caller and complains, and Mrs. Moon answers the phone and pretends that she is some woman fooling around with Frasier. Julia uncovers the truth, and Mrs. Moon immediately gives up Roz. Julia confronts Roz, who orders her to stay away because she doesn't think she's good for Frasier. Julia notes that Roz seems extremely jealous, and they argue. Roz tries to get Martin to side with her against Julia. She finally talks to Frasier and pleads with him to dump Julia. Frasier grows angry at her for interfering in his relationship, and says that it is none of her business. Roz becomes increasingly agitated and emotional, and finally orders Frasier to choose between them, threatening to leave his life forever. Frasier chooses Julia. Roz quits her job and takes the program director position. Meanwhile, Niles and Daphne discuss the possibility of having children, but realize that this cannot happen while her mother is still living with them. They ask Mrs. Moon to leave, and she prepares to return to England. Daphne holds her ground when her mother tries to lay a guilt trip on her; but Niles realizes that, in spite of their frequent arguments, the two don't really want to be on separate continents. He agrees to help Mrs. Moon find an apartment in Seattle.
