Did You Know?


Riker uses a tricorder in this episode. The only other time he is seen doing this in the entire series is in the episode Power Play. See more »


When Picard and Riker set the auto-destruct, the computer asks for a time interval, and after a spirited discussion, they set the time for 20 minutes. In Star Trek: The Next Generation: 11001001, the time interval was set by the computer at five minutes, which suggests that this was the standard interval, and, at the time, their only option, given their situation. It does not suggest, however, that the interval cannot be altered as desired under any circumstances. See more »

Counselor Deanna Troi: You're worried.
Capt. Picard: With reason.
Counselor Deanna Troi: About Worf or Commander Riker?
Capt. Picard: Both. I think it is perhaps best to be ignorant of certain elements of Klingon psyche.

Was This More Dumb Luck or a Truly Clever Play?
4 August 2014 | by (United States) – See all my reviews

The whole setup for this episode is quite good. We have a mysterious void in space where the Enterprise finds itself buried. Since there is nothing on the sensors, there is no escaping it. Add to this, the illusions of a Romulan battle cruiser that actually fires on the ship and a federation starship which has no crew. It is obvious something is toying with the crew. Soon a sort of cat-like face appears on the screen. It is the chosen representation of an alien force that sees the Enterprise as a mere curiosity. It has no respect or concern for the crew. It even kills a bridge officer to watch him die. It is hard to enjoy an episode when the forces working against the crew are so unfathomable that there is no strategy to counteract them. The best Picard can do is to destroy the ship. He and Riker initiate the destruct sequence. The crew gets twenty minutes to get its affairs in order. The entity continues to toy with them. I guess saying enough is enough is the last resort for Picard. Still, the universe is so complex and the villains are around every corner (are there corners?). This episode is clever and dramatic and does keep our attention. Perhaps that's all we can ask for.
