That's a winner!
Clue 1: So is he in this scene or not? The Picard interrogation scene shows Riker sitting at the table where Worf is, but it's footage from the earlier scene when he was Tarses' counsel. All of the other shots do not show Riker in the scene. It's understandable, Frakes was busy directing the episode.
Clue 2: He's standing right there, dude. J'Dhan accuses Riker and Troi of accusing him of stealing the files and sabotage because he's Klingon, even though Worf is standing right there in the room.
Clue 3: Did anyone do the roll? The accident in Engineering resulted in the isolation doors coming down. If Geordi is present for that, he HAS to do the "In before the lock" roll under the door as it closes.
Clue 4: Fine, if you’re in my seat, I’ll sit over here. When Picard enter the Observation lounge and Worf is briefing his staff, Worf is sitting in Picard's usual chair, leading Picard to sit at the other end of the table.
Clue 5: Boldly going not very far this episode. The warp drive was off-line for most of this episode, meaning the best speed the ship could do was impulse. The ship was also never seen at warp, even after the warp drive was repaired.
Clue 6: Is Lieutenant General Mills also in this meeting? Ensign Kellogg was one of Worf's team he gave assignments to in the meeting in the observation lounge.
