Leland Barton, Hesters former research assistant, comes for a visit after a long absence from Seattle. Roz becomes alarmed when Leland confesses his deep affection for Hester. She notes that Leland and Frasier seem to have much more in common than Frasier and Martin (they are both psychiatrists, enjoy sherry and fine art, etc.) and even have many of the same mannerisms. Leland also shares many habits--and a couple of very rare allergies--with Niles. Roz begins to worry that Leland was the boys real father. She accidentally shares her suspicions with Martin, who admits that Hester cheated on him and fears that Roz may be right. Roz tries to assure him that his relationship with Frasier and Niles shouldnt change, even if he isnt their biological father. Martin observes Lelands close interaction with Frasier and Niles and finally confronts him. Leland admits that he loved Hester very much--and that he is gay. Meanwhile, Niles and Daphne make plans to apply for a spot in a prestigious prep school for their yet-to-be-conceived child, but cant come up with a name to write on the application.
