Does its appearance coincide with the arrival of a Federation Starship from the Gamma Quadrant? Find out in “Stowaway” and “Stowaway Part II.” Then stay put as “The Butcher of Bajor” lives out his final moments aboard DS9... but even he isn’t prepared for how things end in “Old Wounds.” Finally, in “Emancipation” and “Emancipation Part II,” a failed escape attempt by slaves from Chiaran ends with explosive results.
