Resurrection

When a stranger beams aboard the station and takes Kira hostage, she is shocked to see that he looks exactly like her dead love, Vedek Bareil. He reveals that he is Bareil - the alternate universe version - and is running from the evil Alliance of his universe. Even though he attacks her, Kira refuses to press charges after he is captured. Sisko is concerned that she is letting his resemblance to her late lover influence her actions, but agrees to allow Bareil to remain on the station.
