The Darkness and the Light

Kira, now heavily pregnant with the O'Briens' baby, learns that Latha Mabrin, a member of her old resistance cell, has been murdered. An anonymous message follows, showing his image and a distorted voice counting the first kill. More of her former comrades die, each death followed by another message. Her old friends Furel and Lupaza come to protect her, but an explosion in the O'Briens' quarters kills them both. Against Odo's advice, Kira tracks the killer to a remote location and falls into his hands. He is Silaran Prin, a Cardassian civilian horribly scarred in a resistance bombing carried out by Kira's cell, and he is hunting down everyone responsible. Kira insists that the Cardassians on Bajor were occupiers and fair targets. Prin plans to remove her unborn child before killing her, but Kira only pretends his sedative has worked. She breaks free, seizes a phaser and kills him.
