Goof: The crew keeps referring to the phenomenon as a distortion ring, but this is an obvious mistake. Either the senior crew forgets that is space and a ring (an 2D figure) can be bypassed by going either over or under it, not only by going around it. To be completely surrounded by the distortion, it should be a sphere. After all, this is space, with three dimensions.
When Janeway wakes up in the holodeck for the first time, she perceives what the Doctor is saying to her as nonsense. However, his statement is actually reversed speech that says, "I can't analyze her neural pathways."
Nitpick: Tuvok encounters the spatial distortion while in command, but cannot alert the crew as the anomaly is interfering with the communications. Then, when he later meets up with Chakotay and Janeway, he talks with them about the anomaly as if they already know about it.
Sandrine: If he won't play pool with you and he won't make love to me, then as far as I'm concerned, he can mop the floors!
The Doctor: Do you see these hands? These are surgeon's hands, created by the most sophisticated computer-imaging technology available. They do not play games and they do not mop floors!
Sandrine: Then you are fired! I will find a new bartender.
The Doctor: I really wish you would!
Chakotay: Tell me something, Tuvok: what does your logic tell you about navigating a maze that is constantly changing shape?
Chakotay: Jealousy's about the fear of losing someone we love. There's no pain greater than that.
The Doctor: Ensign Kim. I was just, uh...
Sandrine: Playing Doctor.
The Doctor: How many times do I have to tell you, madam? I'm a doctor, not a bartender!
Kim: B'Elanna, what are you doing here?
B'Elanna: Just tell me something, Starfleet. Where is here?
Robert Picardo named this as his least favorite from all of the Star Trek: Voyager episodes.
This episode is a bottle show, meant to be a budget-saving episode produced at a time when the series was running out of financial resources.
The quick pacing and piecemeal nature of this episode meant that five extra scenes had to be written into it, after the rest of the episode had been shot, in order to fill out the episode's duration. Another method utilized to add enough time onto the episode was looping of additional dialogue. According to the unauthorized reference book Delta Quadrant, the installment ran short by about eight minutes, and the small character scenes that were added included at least some of the flirtatious banter when Sandrine is attempting to chat up The Doctor.
The episode was also known as "Out".
This episode was written and produced as the penultimate episode of Voyager's first season.
