Aside from a greater interest in socially conscious causes, like the protection of endangered species, the 1989-1990 season also breaks with the past by an episode set in the Old West ("Serenity") and another set in the afterlife ("Passages"). In the former, Jack and Penny (Teri Hatcher in her final appearance) return as prototypes for their present day characters. Murdoc returns, as well--this time wearing a black hat. In the latter, Grandpa Harry (John Anderson) bids adieu. Other fifth year guests include Blossom’s Mayim Bialik ("Cease Fire," "Hearts of Steel"), The Exorcist’s Linda Blair ("Jenny's Chance"), and Jerry Maguire’s Cuba Gooding Jr. ("Black Rhino," "Serenity"). --Kathleen C.
