The Enterprise is mapping the Delta Triangle, an uninhabited sector of the galaxy where a number of ships have disappeared since ancient times. The sensors become unreliable as soon as they enter the Triangle and they detect a Klingon battlecruiser. Before they can hail it, the enemy ship opens fire. The Enterprise returns fire and the Klingon ship instantly disappears. Spock confirms that the Klingons' shields deflected the phasers, and the disappearance doesn't match that of a cloaking device. He suggests that it disappeared for the same reason that other ships have disappeared...

Episode Quotes
Kirk: But we are in the Delta Triangle.
Commander Kuri: I do not accept this.
Kirk: Frankly, Commander, what you accept is of little importance to me. Enterprise out.

Kirk: Got any miracles in your computer, Spock?
Spock: Impossible to predict, Captain.
Kirk: I don't want a prediction.

Kaz: Your willingness to work with your old enemy Kirk. It is not like you, Commander. What do you really have in mind?
Kor: You do know me, Kaz. Very well. What would you think of the Enterprise suddenly disintegrated after our duel ship had pierced the time continuum.
Kaz: I would think my commander had maneuvered brilliantly.

McCoy: Jim, I'm worried about Spock. He's just not acting normal.
Kirk: He's under a lot of pressure, Bones.
McCoy: I know that. But I've never known Spock to act like a pal under any circumstances. Least of all toward Klingons.

Xerius: You will fail.
Kirk: We must try, Xerius. Elysia is, in many respects, a perfect society. But with all its virtues, it is not home. And home with all its faults... is where we prefer to be.
