Lilith unexpectedly comes to town to talk to Frasier about an important matter, while Martin makes every effort to dodge her. Lilith tells Frasier that she is there to ask him for a favor to make her life complete—having another child! She asks Frasier to consider artificial insemination so that Frederick can have a full sibling with the same genetic makeup. After much thought, Frasier politely explains to Lilith that he is opposed to her proposition. However, she manages to change his mind through manipulation, telling him touching stories about Frederick’s childhood and reminding him that he’s their greatest achievement.

A high-strung Lilith accompanies Frasier to the hospital to begin the process. However, Frasier starts having second thoughts about his decision when she makes inappropriate remarks about how things should be done. He suddenly realizes that she is trying to recreate the past now that Frederick is getting older and tells her he can’t go through with it.

Meanwhile, Daphne takes a disastrous road trip to an amusement park in Canada with Mrs. Moon, Roz and her daughter Alice. While she is away, Niles obsesses over a blurry photograph at the end of a roll, which he believes is an illicit shot of Daphne. However, he is disturbed and embarrassed when he realizes that it is actually a shot of Martin’s chest.

Lilith’s hopes for a complete life are restored on the plane ride home when she reconnects with a fellow male passenger she met on her way out.
