The Enterprise encounters a mysterious entity, which turns out to be two-dimensional and is towing the ship. Just then Counselor Deanna Troi finds herself devoid of her telepathic powers, an inedited loss of control she finds more then terrifying, indeed she hands in her resignation. Every attempt to fight the aliens fails, and it's forcing the Enterprise straight to fatal danger. Only at the last moment Diana comes up with a 'two-dimensional theory'... Written by KGF Vissers

When the Enterprise is trying to get the attention of the two dimensional creatures, they fire photon torpedoes 7km in front of the beings. Worf states that he has fired, then states that it is 5 seconds till detonation. When that doesn't work, they fire directly into the field of beings. This is at least 7km closer to the Enterprise, but Worf still states that it takes at least 5 seconds for the torpedoes to reach their destination and detonate. See more »

Deanna at Her Worst
24 August 2014 | by (United States) – See all my reviews

I have no problem with Deanna Troi going into severe depression when she loses her empathic Betazoid powers after some kind of energy surge. She suddenly realizes that the greatest gift she has has disappeared. I could have accepted her desperation had the plot evolved a bit and time had passed. It's almost as if they were thinking we need to have actual time end in a few hours. For heaven's sake, there are so many physical conditions that take a couple days to heal, like getting your sight back after a blinding flash, or temporary paralysis after a fall. Had she gone into this deep place a month afterward, it might have been more believable. As it is, she begins to attack her friends and whine to her patients. Even in the imaginary world of Star Trek, her responses are portrayed as childish at best. She is also the person who extends comfort to others. How can she be so short sighted. After some quite strong episodes and one clinker, it just doesn't work for me.
