Duet (Episode 19)

Kira faces a horrific reminder of Bajor’s occupation when a sick Cardassian comes to Deep Space Nine with an illness revealing that he has ties to an infamous prison camp commander… and may even be that man.
Perhaps Deep Space Nine’s first truly exquisite episode, this bittersweet look at the trauma of the Cardassian occupation of Bajor makes for an incredibly dramatic, emotional story—one that importantly examines just how the horrors of the Cardassians’ cruelty destroyed the lives of Bajorans and Cardassians alike.
