The week-long national syndication window opens for the 166th episode of Star Trek: Deep Space Nine. This episode continues a tightly-serialized eight-episode run-up to the series finale. Louise Fletcher guest stars. 
Stardate not given: When Sisko reluctantly tells Kasidy of the Prophet’s warning against their marriage, the wedding is off – but then the Emissary does some soul-searching about whether to heed the dire prediction, or follow his heart. Meanwhile, Kai Winn finally gets a vision, apparently from the Prophets, telling her to expect a “guide” who will aid her in the restoration of Bajor; then when Dukat arrives, posing as a Bajoran farmer named Anjohl, he begins to insinuate himself into her confidence. And on the Breen ship, Worf and Ezri are held captive and interrogated as the ship proceeds to a rendezvous that may spell disaster for the Alpha Quadrant.
