When a Runabout crew finds Q's former traveling companion Vash (Jennifer Hetrick) in the Gamma Quadrant, Q (John de Lancie) comes to the station in an attempt to convince her to rejoin him. In a related subplot, Vash and Quark plan an auction for rare Gamma Quadrant artifacts Vash has collected during her two years on the other side of the wormhole. In a less than interesting plot turn, one of the artifacts turns out to be an embryonic lifeform trying to return to the Gamma Quadrant, placing the station in some rather uninspired danger.
There's very little meat here. Most of the story exists as an excuse to hang the Q dialog scenes on. The rest of it is mired in that evil stuff known as Trekkian technobabble, used to explain why the station is catapulting to its doom. It's unfortunate to use Q in a show featuring such banality, considering he's the embodiment of omnipotence. Then again, Q has usually been the source of comedy rather than insight in most cases ("Q Who?" notwithstanding), and the show's comic attempts are fairly successful. Quark and Vash make an engaging scheming pair, Bashir's inept attempts at womanizing are fittingly annoying, and Q's acerbic lines poking fun at the DS9 crew are amusing. At one point he actually says "Picard and his lackeys would've solved all this technobabble hours ago." The show features superficial fun and a good performance from de Lancie, but don't look for much depth in the plot.
