Goofs

Picard's fingernails grow from being near the fruit. However, you can see them being longer before he is near the fruit, as he enters the room and operates the computer.

After Picard, Data and Troi beam over to the bridge of the Enterprise frozen in time, Data tries to work the Comm station and tells the Captain that "the equipment is no longer functioning." Seconds later, Picard pulls up display after display from the Tactical station detailing current Security team deployments. As he moves his hands across the panel, you can hear the clicks and beeps of the computer acknowledging his requests.

After Picard has the sudden nail growth, Geordi and Data move to different consoles to move the runabout away from the temporal distortions. About 30 seconds go by and Geordi calls Picard to the bridge. It is shown that Picard is rubbing his hand, and his fingernails are back to normal length.

Though it could be said that he may have barely had time to use some sort of modern technology to instantly cut his nails, no such tool is visible on the table where he is sitting, and it is doubtful that his first priority in that situation would be to cut his nails, especially with the ship shaking violently while it was being moved and then put back the tool, all in 30-40 seconds.

His fingernails would also not have shrunk on their own, as they were grown due to a temporal anomaly and having grown naturally in an accelerated time field.

At the end, when Riker visits Data in his quarters, the door across the hall shows them to be on Deck 36. Previous episodes established that Data's quarters are on Deck 2.

When the shuttle arrives at the two ships, it is stated that the energy beam is coming from the ship's deflector dish which makes up the forward wall of the engineering section. Later, in an external view, after Picard, Troi and Data leave the bridge, the energy beam can be seen coming from the rear left area of the "neck" of the ship.

Picard is exposed to a "temporal anomaly" around the fruit bowl for less than ten seconds of real time. This causes his fingernails grow around a half inch longer. Data reports that time is passing at 50 times the normal rate, which means that Picard's hand was inside the anomaly for less than 500 seconds (around eight minutes). His fingernails would not have experienced any visible growth in this amount of time.

When the warbird fires on the Enterprise the tactical officer can be heard saying that shields were down to 23%. However the Enterprise was in the middle of evacuating the crew of the Romulan ship, their shields would have been down, otherwise the transporters would be inoperable. Plus the power transfer beam would not be possible if either ship's shields were up.

When the Enterprise and the Romulan warbird are first seen frozen in time, Troi notes that the Enterprise has been damaged under the port nacelle, and Picard notes that a beam of some kind is being sent to the warbird from the Enterprise's deflector dish. The damage is clearly on the underside of the saucer section, and the beam is coming from a non-descript spot on the hull above the deflector.

When Picard becomes delusional due to stress from the temporal shift he draws a smiley face in the expanding cloud of gas from the warp core breach. Data has already confirmed that time is not frozen as they originally thought, it is just moving forward at an infinitesimally small rate. Which means, even though it is moving at a tiny fraction of its normal speed, the cloud of gas coming from the warp core is actually super-heated warp plasma being released by the core breach, as such Picard's finger should have been vaporized the second he touched it.

The stars appear to be moving when the Enterprise and the Romulan Warbird are frozen in time. Since the plot-line includes highly concentrated time distortions, it is perfectly feasible that the stars will move as normal while the trapped vessels will remain frozen.

Picard, Data, and Geordi make no reaction to the fact that, from their point of view, Troi would've instantly gone from sitting down to standing up after first freezing in time. However, Geordi was telling a very interesting story at the time, so all eyes were on him, and apparently no one noticed Deanna's sudden change in position. Although human peripheral vision responds to sudden motion, thus attracting attention to the latter, it's not designed to handle time-skipping as a real motion, so it's reasonable that Deanna's change in position wasn't noticed at once. That being said, Picard did notice the change just a few moments afterward, when he asked Deanna if everything was alright. Interestingly, he's the only one of the three with human vision.

At the end, Data is experimenting with the human perception of time. He notes that humans often perceive time as being variable, when the passage of time is actually fixed (e.g., a watched pot never boils). This is actually incorrect. Einstein demonstrated that the passage of time can be affected by other factors, such as speed or gravitation. However, for an observer a specific time frame, time does pass at a consistent rate. This is relativity, time does vary, but it is relative to the observer.

At the beginning, when Picard is telling the others about the workshop he attended, he gets up and walks towards the Replicator, picking up Geordie's cup along the way. While standing at the replicator, he doesn't give it instructions that he wants 2 coffees (or teas). It then just shows him turn around and pick up the 2 cups as if already filled.

Actors required to appear as if they are frozen in time can be seen to move slightly and blink at times.

At the beginning, the deep scratches on Riker's forehead were not made by a cat.

When Picard uses the replicator at the beginning, a crew member can be seen moving out of its reflection.

Protective glass can be seen when the Enterprise helm console explodes and the crew member is thrown out of his chair (39:50). As the Romulan officer takes the seat, the glass can be seen to the right of the console.

At the end, after Picard uses the runabout to stop the energy beam from the Enterprise, the Romulan Warbird disappears. Picard himself also says that the timeline has been restored to normal and the warbird is gone. But the narration by Picard just after that says they successfully rescued the Romulan crew from the ship and are en route to the Neutral Zone to bring them home.

When questioned later about the first instance of the time anomaly, Troi says that her crewmates appeared to freeze for "four, maybe five seconds." They are actually frozen substantially longer than that -- just short of 20 seconds.
