Pathfinder - S6-E10
Deliberate mistake: When Barkley goes to see Admiral Paris at Starfleet Command, as Nicole tells the Admiral that Barkley won't go away, there's a photo of the Admiral's son, Tom, on the desk. Tom's Starfleet combadge is at his uniform's right side (it should be on his left). But during the conversation there's a closeup of this photo, and Tom's combadge is now at his left side. This is not a flipped shot. The combadge position in the photo was not edited in the 1st shot, though it was corrected in the 2nd shot. (00:24:00)
