Station log: Odo has received a coded message from Gul Russol, one of his most reliable contacts in Cardassian space—and whom he thought was executed when Cardassia joined the Dominion. But he was Odo’s most reliable informant so he has to answer the call. He takes the Rio Grande to the rendezvous, only to find that Russol really is dead, and the message actually came from Weyoun—and he wants to defect. He claims that his life is in danger because he’s being scapegoated for the failure of the war to have already been won.
Sisko needs the Defiant’s malfunctioning gravity net to be working when he returns from a conference on Bajor in three days, but the quartermaster, Chief Willoughby, says it’ll take three weeks for the part to arrive. O’Brien has no idea how to make that happen—but Nog has a few ideas, and goes off to work his Ferengi magic, to O’Brien’s dread.
