Lois' often-divorced sister (voice of Julie Haggerty) visits---and falls in love with Mayor West. He falls for her, too, and they decide to wed. Peter's also excited because he has never had a brother and he figures that a brother-in-law is close enough. Also appearing are Robert Loggia (as himself), and "Family Ties" alums Meredith Baxter and Michael Gross (as Elyse and Steven).
