Corrected entry: Data mimics the rest of the crew when Captain Sunad of the Zalkonians makes all the crew unable to breathe. Data is on his knees close to floor and is rising when "John Doe" heals the crew. Data is an android and should have just remained seated at his post.
Corrected entry: When Geordi, Picard, and Riker are discussing Data's shuttle accident in Picard's ready room, Picard addresses Geordi as "Lieutenant." In the American navy (which Starfleet is adapted from), a Lieutenant Commander like Geordi is addressed as "Commander", as it is higher in rank than a regular Lieutenant.
Corrected entry: When Tasha Yar and company first exit Ten Forward in the alternate timeline, watch through the doors as they open. An extra can be seen stood still in midstride in the passageway, before nervously noticing that the doors have already opened and that she has missed her cue to begin walking past. She then begins purposefully marching down the passage.
Corrected entry: In the beginning of the episode after the explosion, Dr Crusher wants to stay and tend to The Wounded despite the danger of further explosions/terrorist attacks. Picard, Data, and Worf all tell her to go back to the Enterprise but she refuses. This leaves a perfect opportunity for her to be kidnapped. If she had just beamed the five or six wounded people injured people to the Enterprise sickbay, she would not only have removed herself from danger but also have taken The Wounded to a state-of-the-art medical facility instead of feeling around for broken bones and telling them not to worry about the gaping bloody holes in their bodies.
Corrected entry: Throughout the episode, Lt. Richard Castillo wears a Type 2 phaser, which was seen in Star Trek II. He should wear the phaser introduced in Star Trek V, or any phaser consistent to the timeline. The movie [ST V] and the episode were shot in the same year. The old phaser is clearly visible in the sickbay scene at 18:18. (00:18:15)
Corrected entry: It's a given that the Enterprise had the ability to use phasers to fire at the aceton collectors, but since they run on energy, why didn't they use photon torpedoes to destroy the collectors? They don't rely on regular energy, but explosive force to do their destructive capabilities. Even those collectors wouldn't be able to withstand a matter/anti-matter explosion of a photon torpedo without any type of shielding.
Corrected entry: About halfway through the episode, Wesley comes to the realization that his nanites are causing the malfunctions on the ship, because they escaped from the lab. Shouldn't he at least have know that the nanites had escaped, when he awoke at the beginning of the episode and found that the container had been left open? He might not have known they would become destructive, but he would have known they had escaped.
Corrected entry: Picard decided to beam the leader of the village to the Enterprise. While on the bridge, he orders Data to beam her directly to transporter room one as soon as she is alone. Picard goes to the transporter room, tells the crewman he will handle this himself, and then proceeds to beam her up without notifying Data not to do so.
Corrected entry: The Mintakans are stated to be at Bronze Age level of technology. However, while Riker is escaping with the injured Palmer, the pursuing Mintakan is carrying a 20th-century compound bow (a bow with pulleys). It is simply not possible to make a compound bow with Bronze Age technology.
