For the Cause

The Federation is sending industrial replicators to Cardassia, and the shipment passes through Deep Space Nine. Odo and Starfleet security officer Lt Cdr Michael Eddington warn Sisko that his girlfriend, freighter captain Kasidy Yates, may be supplying the Maquis. When she refuses to let her cargo be inspected, Sisko and Worf follow her ship, the Xhosa, into the Badlands and watch it hand supplies to a Maquis vessel. But with Sisko away, Eddington overpowers Kira, orders his security team to move the replicators onto a waiting ship and escapes with them. He then contacts Sisko to admit that he has been working for the Maquis all along. Kasidy later returns to the station alone to give herself up. In a lighter subplot, Dukat's daughter Ziyal tries to befriend Garak, who at first suspects she has been sent to kill him but comes to welcome her company.
