Continuity mistake: In the scene right before the shuttle's crew finds the Romulan ship and the Enterprise, Geordi calls the shuttle craft's cockpit to explain the temporal disturbances. Captain Picard, Troi and Data walk into the shuttle's cockpit room and Troi puts her right arm on Geordi's chair. As Geordi, Data and Captain Picard are talking you can see Troi's wrist hanging off the chair, but when the camera cuts directly in front of Geordi her whole wrist is on the chair. The camera then cuts back and you can see that Troi's wrist is still hanging off the chair.
Continuity mistake: The stardate given in the previous episode is 46578.4 and the stardate of the episode after this is 46682.4. In this episode, Picard records the stardate in his log as 46759.2. There was either a typo in the script or the actor misspoke the scripted 46579.2. This isn't excusable as a character error, because the episode is accepted in Trek lore as occurring on the date Picard states.johnrosa
Continuity mistake: In the scene where Captain Picard reaches for the aged fruit, he screams while holding his right wrist with his left hand. As Troi, Geordi, and Data rush in you can see Captain Picard holding his wrist up in the air. The camera then cuts directly in front of Captain Picard and you can see Troi scanning his wrist but he isn't holding his wrist anymore. The camera then cuts directly in front of Troi and Geordi and you can see that Captain Picard is still holding his wrist. The camera then again cuts back to Captain Picard and he isn't holding his wrist anymore.
Continuity mistake: In one scene on the planet, Riker's clone is lying under a table fixing something and Riker is sitting in a chair talking to him. There are two camera angles used. In one angle when the clone is talking and a body double is sitting in the chair he is facing directly towards the table but in the other camera angle where you can only see Riker, the chair is at an angle facing towards where his clone is lying on the floor.
Continuity mistake: William Riker is playing cards with La Forge and Worf. The camera is focusing on Riker and there is no 4th chair. When Tom Riker enters, William says "Why don't you join us" and now removes his trombone from the 4th chair which has suddenly appeared. (00:31:25)Klaus Egvang
