The Empath - S3-E12
Continuity mistake: After partially healing him, Gem falls away from McCoy and lands, unconscious, perpendicular to the dais he's lying on. When Kirk and Spock rush over, however, she's suddenly moved several feet away and is now lying parallel to the dais. (00:44:50 - 00:45:35)
Continuity mistake: When Miramanee and her companion first see Kirk at the obelisk, the two women are standing, holding their fruit baskets, just inches from each other. In the very next, reverse angle shot, they're suddenly several feet apart. (00:09:10)
For the World is Hollow and I Have Touched the Sky - S3-E8
Continuity mistake: Natira orders the landing party to kneel before the oracle. Spock does so about a foot-and-a-half to McCoy's left. As the shots change, Spock "jumps" to McCoy's immediate side, then back to his original position, etc. (00:10:35)
For the World is Hollow and I Have Touched the Sky - S3-E8
Continuity mistake: Kirk orders Sulu to match speed with the asteroid, but in the next external shot the asteroid is closing in on the ship.
Continuity mistake: At the end when the entity left the Enterprise, it came out of the secondary hull, however it left from the engineering dept. The Engineering dept. is located in the back of the primary hull.
Continuity mistake: In the opening scenes, Sulu's retractable viewer isn't there when the Klingon ship approaches on the view screen. But a moment later in a closer shot, the viewer is suddenly in front of him, fully extended. (00:01:05)
Continuity mistake: When Spock orders the phasers to fire, they shoot outward from the ship at an angle from each other, but when they hit the asteroid they converge at a single point. (00:24:00)
Continuity mistake: When Losira appears to D'Amato, he looks up from his tricorder, startled. The shot then changes angles, and D'Amato looks up at her all over again. (00:11:55)
Continuity mistake: When Scott orders Sulu to fire phasers to punch through the force field, the two phaser beams are diverging when they leave the ship, but converging somehow (space mirrors?) when they strike the planet. (00:41:20)
Continuity mistake: When Kirk is being beamed aboard near the end, the crewman operating the transporter has a single lieutenant's stripe. But in the close-up of his hands on the controls, the stripe changes into the braid of a lieutenant commander. (00:46:40)
Continuity mistake: When Kirk splits up the landing party, he asks McCoy to further inspect the vegetation. In the two shot, McCoy isn't wearing his tricorder, but in close-up, it's there, strapped over his left shoulder. Cut back to the two shot, though, and it's gone again. (00:10:20)
Continuity mistake: In the beginning Chekov disappears off the bridge for a moment and is replaced by a blond haired crew member, then he returns.
Continuity mistake: As Mira is speaking with the alien's voice, Spock is behind a console that has a piece of equipment attached to it. From behind Spock, the piece is to his left, but the close ups of Spock show him close to and directly in front of it.
Continuity mistake: On the bridge, watch Uhura. She goes from both hands on her controls, to left hand on her earpiece in a split second.
Continuity mistake: Lt. Galloway, who was killed off the season before in "The Omega Glory," is resurrected without explanation for this final episode. (00:24:25)
Continuity mistake: When Elaan visits engineering, the close-up shots of Scotty show a security guard wearing a black utility belt standing in the background. But the man is missing in all the full shots. (00:13:15)
Continuity mistake: When Mr. Scott asks Watkins to check the bypass valve, Watkins is facing the engineering boards with both hands on the panel. When we cut to a different angle, however, he's suddenly jumped to a position facing Scott with only one hand on the panel. (00:18:35)
The Empath - S3-E12
Continuity mistake: The bruises on McCoy's face change configuration, color and texture between the time Kirk and Spock first find him and the scene where Gem heals him. (00:34:15 - 00:40:30)
Continuity mistake: As Garth brings in the chair and orders the governor's torture, the pedestal fruit bowl on the table in front of Kirk keeps moving back and forth in relation to him and to the wine pitcher. (00:22:40)
Continuity mistake: In Kirk's log entry, which he somehow makes from jail without a tricorder, he states that 5 witnesses heard him speak to the "spirits." This isn't true, and Kirk ought to know it. The crowd rushed in through an archway after he spoke to Spock and McCoy, and they were all too far away before to hear him. (00:10:50 - 00:26:00)
Answer: Kirk was getting his physical and Dr. McCoy probably turned off communications, because if he hadn't, Kirk would have left and headed straight for the bridge, leaving McCoy irritated.
