Second Sight
Sisko meets Fenna, a mysterious woman, on the fourth anniversary of the death of his wife at the Battle of Wolf 359. Fenna disappears on more than one occasion before he can learn very much about her. The third time she disappears it is right before his eyes.
Dax and Chief O'Brian help Professor Gideon Seyetik, a visiting scientist, prepare to reignite Epsilon 119, a dead star. Sisko gets a bit of a shock when he meets Nidell, Seyetik's wife, and she looks just like Fenna. Sisko confronts Nidell but she doesn't recognize him.
Sisko and Dax accompany Seyetik and Nidell aboard the Prometheus, the ship that takes them to Epsilon 119. Fenna appears aboard the Prometheus after Nidell falls into a coma. Gideon recognizes her. He saw her once before, a few years prior. Dax believes that she is the unconscious manifestation of Nidell's mental energies.
