Second Sight

DS9 Season 2 Episode 9
Air Date: November 15th, 1993

Professor Seyetik arrives at DS9 with his ship the USS Prometheus (different then the one in Voyager episode Message in a Bottle). He is described as one of Federations greatest minds and he is tasked with reigniting a star to make one of it's planets habitable. This plot goes as one would expect, leading up to a difficulty, which leads to Seyetik piloting a shuttle on a suicide mission into the star.

The reason for this is due to the other plot. Cmdr. Sisko meets a woman on DS9 named Fenna whom he falls in love with. But she keeps disappearing when he looks away. We eventually learned that Fenna was a second personality of Seyetik's wife Nidell and she is able to astral project the Fenna personality without even knowing it exists. The problem is the Fenna personality when it comes out slowly kills Nidell. Seyetik's suicide is able to oppress Fenna saving Nidell's life.

Quotes

"Personal log, stardate 47329.4. I finally realize why I've had trouble sleeping the last few nights. Yesterday was the 4th anniversary of the massacre at Wolf 359, the fourth anniversary of Jennifer's death. I'm not sure what bothers me more, the date itself, or the fact that it almost passed unnoticed." - Cmdr. Sisko

"I never fail. Well, I did once; but I found it didn't agree with me, so I swore never to do it again, and I never break my word." - Dr. Seyetik

"When I came here, I thought I was looking for a place - somewhere I belong, but I was wrong. I wasn't looking for a place, I was looking for a person. I was looking for you." - Fenna
