Profit and Loss, DS9 2
Casablanca-esque shenanigans aboard the space station as Quark discovers that his Ilsa is working in the Cardassian Underground. A completely new side of Quark is seen – one that is completely real, in love, believable. We also learn that Garak is, indeed, more than a humble shopkeeper. As with most of the best DS9 episodes, Sisko stays out of the way and we focus mostly on the aliens.
