Corrected entry: When Riker's father is talking to Troi, he says Riker has just been offered his first command (the USS Aries). However, Riker was already given a offer to command the USS Drake, which he turned down to join the USS Enterprise. This would be at least his 2nd offer to command, something his father would be aware of given his position, and following his son's career has he has.
Corrected entry: On the Pasteur, when Data reports another ship de-cloaking, he says "It's the Enterprise." He uses a contraction rather than saying "it is." Even though it's in the supposed future, many times Data has pointed out he can not use contractions.
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: Apparently when it came to taking the ship into the asteroid, the entire bridge crew conveniently forgot that Galaxy class federation starships can separate. The obviously prudent course of action would be to separate the ship and send the star drive section (the narrower section) into the asteroid while the saucer section (the wider section) stood guard outside. The only reason this wasn't done was to provide drama for the rest of the episode when the Romulans collapsed the entrance to the chasm.
Corrected entry: As a non-corporeal entity enters and damages the ship's electronic systems, it causes the ship's engines to shut down. The ship, traveling at Warp 6, slows down and stops when the engines are shut down. However, in reality, ships in space only need the engines to get up to speed. Inertia will allow the ship to continue without the engines "pushing" the ship, because in space there is no friction to slow the ship when the engines shut down. The ship would continue on its current course at its current speed when the engines fail. Even if the warp field collapsed they wouldn't stop entirely.
Corrected entry: At the end of the episode, as Ro and Picard walk through the Bajoran camp, she states there is one condition to her continuing in Starfleet, at which point she puts on her Bajoran earring. In this episode and all other episodes she wears it on her left ear. However Bajorans wear the earring on the right ear, as stated throughout Deep Space Nine.
Corrected entry: When Lwaxana is in the transporter room demanding to transport down to the planet, O'Brien leaves Lwaxana and Troi alone. Before he does, he enters a code to lock the transporter panel, and the word LOCKED appears inside a red rectangle. At the end of the scene, when the camera pans out, the word LOCKED is no longer there.
