Diane Chambers comes back into Frasier’s life when a play she wrote is being staged in Seattle. Although Frasier denies any hurt feelings over once being left at the altar by Diane, Niles suggests Frasier confront her over his resentment at her abandonment. He does so only after Diane admits that her life is a shambles, and that she needs Frasier’s financial backing to produce her play.

Over Niles and Martin’s objections, Frasier agrees to finance Diane’s play, and tells his brother and father that he and Diane have both changed. However, when Diane invites Frasier to a dress rehearsal of her “feminist odyssey,” he instantly recognizes it as a thinly veiled reprisal of her time at the Cheers bar, complete with a bartender named “Stan” and a pompous psychiatrist character named Dr. Franklin Crean.

When Frasier sees his stage character struggle with being jilted by Diane’s doppelganger, he erupts with an outburst in which he refers to Diane as the Devil. Later, Diane apologizes, and they part as friends.
