The Doctor's experiment with daydreaming gets out of control when an alien race compromises his program. The aliens bully passing ships for supplies but, before doing so, first consult their command - The Hierarchy. One of the aliens, mistaking the daydreams for reality, gets permission to attack. Upon realizing his mistake, he offers to help Voyager but only if they act out one of The Doctor's fantasies, where he is in command of Voyager. Written by Meribor

Did You Know?


In The Doctor's daydream when there is an imminent warp core breach, the computer gives uncharacteristic alerts, saying "Warp core breach a lot sooner than you think!" and "Last chance to be the hero, Doctor. Get going!" See more »


Kim calls Captain Janeway and Torres and suggests they come to the holodeck. Janeway responds by saying "We're on our way" and they both leave. In the next scene as The Doctor sketches, only Captain Janeway enters the room, joining Seven and Kim observing the Doctor. As the scene switches to a bridge scene, Torres, without entering the holodeck, suddenly appears with Captain Janeway, Seven and Kim. See more »


[first lines]
The Doctor: Somewhere, in that totality known as the universe, is a galaxy called the Milky Way. Tucked into the corner of that galaxy is a planet named Earth. On that planet is a city called Mantua. Go straight ahead, past the fountain, turn right, then left, and right again. You'll find yourself walking along the water, listening, as a man sings of his beloved's unfaithful heart. And even the fish begin to weep. Quando La Donna E Mobile.

Another annoying doctor episode!
12 September 2019 | by herbie-17See all my reviews

Seeing the doctor being his even more arrogant than usual self (mixed in with him getting all the attention) makes this episode stupid, not funny. Fantasy Star Trek episodes are never successful (Barclay and his was just as bad).

Also, who on god's green earth told Robert Picasso that he could sing. As a trained singer his La Donna e mobile is truly terrible (then later on he gets a whole episode dedicated to him being an opera singer. Oy).
