Corrected entry: In the beginning, when the doctor is activated, he immediately asks who activated him. The computer tells him he was activated when a red alert was initiated. But then he finds out no one is on board, so there was no one to initiate the red alert at that moment. He should have been activated much earlier, when the crew was still on board and under red alert, even in a simulation.
Corrected entry: At the beginning of this episode, we are told it has been 10 months since Voyager was transported to the delta quadrant. However Ensign Wildman is still pregnant at this point in the series and doesn't actually go into labour until series 2 episode 21 (deadlock). She must have been pregnant before boarding Voyager, as her husband is still in the Alpha quadrant. That is one long pregnancy.
Corrected entry: If Kellin spent multiple weeks on the ship, certainly there would be security surveillance evidence that she was there. Even if she didn't visually show up on the video, people would be seen interacting with an invisible someone. Similarly, the Doctor would either be able to see her and remember or not be able to see her and figure out that people were interacting with an invisible person. And what about the ship's logs? People would certainly have talked about her in their logs.
Corrected entry: When the two Voyagers initially try to merge, the damaged voyager has to evacuate all the crew to the engineering deck (deck 11) and then shut down life support elsewhere to save power, leaving the rest of the ship uninhabitable. However, after the attempt fails and with no prior notice, Kes and Janeway are able to travel from the good ship to the damaged one via the rift on deck 15. They have no problems with this, despite the fact that they should not have been able to breathe on arrival with life support turned off.
Corrected entry: At the start, Captain Janeway reveals that she has discovered Tuvok's birthday. Then she says it's not long before he hits the big 3-digits (meaning 100 years old). However, Tuvok was 107 when he infiltrated the Maquis and they've already spent 6 years on Voyager. Even if she didn't discover his birth year and was only guessing. Tuvok would not have replied with "indeed" but pointed out she is wrong.
Corrected entry: When we see the now blind Tuvok shaving, he is using a metal blade, the type still used today, and promptly cuts himself with it. However in TNG, Geordi La Forge (also blind, but using a VISOR) is shown using a bladeless razor with a little light beam that wouldn't cut him. One of these should be available on Voyager, over 10 years later. Lack of power can't a problem, as Tuvok had the lights in his room on the whole time, despite not needing them on account of being blind.
Corrected entry: While Ensign Ballard is trying to dazzle Torres, she switches between English and Kobali. Torres gives her a look and when questioned, she tells her, "You were speaking Kobali." Others in Engineering are also directing strange looks toward Ensign Ballard. The problem is that the Universal Translator should be taking care of this, causing the others to only hear what is being said in their preferred language.
Corrected entry: Within the first 15 seconds as the camera pans the crowd before the Tsunkatse match, we see a good 30 or so federation crew members. Impossible seeing as they have not come across this event before, and the only Starfleet crew in the Delta quadrant are on Voyager. (00:00:15 - 00:01:00)
Corrected entry: When Chakotay's comet removal simulation erases 8,000 civilizations, Annorax tells him that 4 billion years before, material from the comet was the catalyst for the eventual development of several civilizations. However, comets, by their very nature, are short-lived, around 10,000 years. There is no way a comet that seeded life across multiple solar systems 4 billion years earlier would still exist.
Corrected entry: Both the Borg and Chakotay reference that it would take months for Voyager to cross Borg space. The Borg use trans-warp regularly, which is the method Voyager eventually arrives home at the end of the series. The Borg could have scooped up Voyager and had them not only on the other side of Borg space, but all the way home in less than a day. Janeway really missed an opportunity in her negotiations.
Corrected entry: After Captain Janeway instructs Seven of Nine to match Voyager's course and speed with the Delta Flyer, the scene cuts to an external flyby of the Delta Flyer, followed by what is presumably Voyager (an Intrepid-class ship), but the ship following the shuttle is a Galaxy-class vessel with curved, fixed pylons for the warp nacelles. Voyager's nacelles pivot, and look nothing like that of a Galaxy-class starship. (00:29:25)
