Caleidoscope - S2-E4
Character mistake: The chess set in Dr. Pierce's home office is set up incorrectly. When the men are set up properly, each player has a light colored square in the right-hand corner. The board as it appears in the show is set up so that the light-colored square is in each player's left-hand corner. This "beginner" mistake puts the king and queen in the wrong positions.
Character mistake: When David encourages the gang to dance at Scott's birthday party, David mistakenly calls Kelly by her actress' name, Jennie Garth. He says, "Scott, you're off, Buddy. Jen, kind of getting into it."
Character mistake: Bellamy calls Monty "Murphy" when they get back to the Arc and he is losing oxygen.
Character mistake: When Harlan Edwards collapses and Dr. Arcane tells them to clear his airway, one of the other doctors addresses her as "Dr. Cane."

Character mistake: Throughout the whole series Jin and Sun refer to each other as "yobo." The subtitles continually translate "yobo" as either "Jin" or "Sun" which is incorrect. "Yobo" is Korea's version of "dear" or "sweetheart."
The Short Day of Private Putnam - S2-E28
Character mistake: Hanley's call sign is Checkmate King Two. But his radio man recites, "Checkmate King Two, this is White Rook." Should have been the other way round.
Character mistake: Dr. Warren Hughes calls Allison the head of GD, but Fargo is the head of GD in this timeline. (00:25:54)
Suggested correction: In this episode Allison is the head of GD. Yes, Fargo is the head of GD in this timeline but transferred the title "temporarily" to Allison so that he can go on the Titan mission.
Character mistake: When Hunt was interviewing Rocket, he asked him who killed the "P*ki". At the time, the Asian man who had been shot was still alive in hospital, only to die later in that episode.
Character mistake: When the boy is brought to camp that was shot, the Corpsman repeatedly states "he's been zipped by 5.56, Marines shot this boy." It was then assumed that Trombley shot the boy with his M240 SAW. The M240 SAW is chambered in 7.62 x 51mm. Either the Corpsman is incorrect or Trombley didn't shoot the boy.
Suggested correction: The weapon Trombley uses is a M249 SAW, which is chambered in 5.56mm.
Character mistake: When Billy Bones gives himself in to the redcoats, he states he is Long John Silver. In one of the next cuts, he talks about Silver in third person. The governor shows no shock and they keep talking as if Billy Bones had said at the start of the conversation who he truly was. Then he instructs the governor on how to take on "himself" and Flint.
Character mistake: In the 7/19/19 episode, Rafe tells Gabi that, even if she can open the briefcase she stole from Xander, nothing she finds would be admissible in court as evidence, because it is "fruit of the poisonous tree." Rafe is a police officer, but he's wrong about this. The exclusionary rule only applies to searches by police. If a private citizen obtains evidence illegally, such as by trespassing or theft, it actually is generally admissible in court, although the citizen may be subject to prosecution for the illegal action.
