What They Saw in Southie High - S1-E2
Other mistake: Agent Rohr asks who the cold case is related to. A dossier is given to him and the front cover contains a photograph and the name "Kanicki, K". Agent Rohr says "Kelly Kanicki" but there was no indication of the full name, just the initial. (00:08:30 - 00:09:00)
The Mind of Simon Foster - S3-E23
Continuity mistake: When the pawnbroker closes his metal gate, he's facing the wire mesh. When the shot cuts, he's instantly facing away from it. (00:10:15)
Factual error: Haloclines are referred to throughout, and depicted occasionally as some sort of underwater tornadoes. Haloclines are in fact just salinity gradients, and look nothing like they do on the show.
San Junipero - S3-E4
Continuity mistake: Near the end, Yorkie gets into a red left-side drive convertible, then is seen driving on highway in the same car but with right side drive. Following scenes are of a left-side drive car. (00:58:00)
Audio problem: They went to an investigator to let him listen to the audio. The audio with the woman screaming and the gasp, the gasp was Zak, not another apparition.
The M.O.D.O.K. That Time Forgot! - S1-E2
Character mistake: M.O.D.O.K. refers to Hoobastank as "the Beatles of the late 90's." Hoobastank only released one album in the 90's, and they didn't become popular until after they released their second album in 2001.
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.
Continuity mistake: When Gary is at the end of the table talking about Golf, he's actually seated in front of the table as seen by how he grabs his cup in front of him. In the very next shot, he's no longer sitting in front of the table and is sitting past it.
Plot hole: After Grant finishes her video confession, Latif puts the video recorder in his cargo pant pocket. A few scenes later, he's blown up without ever having taken the video camera out of his pocket. He was at the epicenter of the explosion and he and his clothes were very much on fire, which should have completely destroyed the video camera and its recording.
Episode #2.1 - S2-E1
Factual error: Season 2 is set in 1979. Bill Tench and his wife are leaving the church and going to their car. Behind their car is parked a 1981 Chevrolet Celebrity.
The Family - S1-E6
Character mistake: The pharmacist says she's sorry, but they don't have the drug Lamotrigine in stock, so would the generic be okay?Lamotrigine is already the generic form of the drug Lamictal. (00:28:23)
Winning Through Intimidation - S1-E15
Continuity mistake: Panik's Metal Guardian can be seen on the field several minutes before he actually plays it. (00:10:30 - 00:13:00)
Revealing mistake: In brother Justin's padded cell, the far wall is obviously a painted backdrop. It even flutters when the orderly and doctor walk in! The only solid part is a couple of feet at the end, that Justin leans up against.
Containment - S1-E5
Continuity mistake: At the end of the episode, when the bad guy is preparing the syringe of small pox, he follows the usual method of tapping out any air in the tube - when he is shown injecting himself, a large air bubble is back in the syringe (which would probably kill him quicker than the smallpox).
Continuity mistake: Throughout the series, the Barbers pull their cars straight up their driveway. But the cars are nearly always shown coming back down the driveway driving forward.
Factual error: Possibly a mistake from the novel on which the series is based, but although he later became Bishop of Hereford, St Thomas Cantilupe wasn't baptised in Herefordshire. He came from Buckinghamshire.
Thank You for Not Driving - S1-E3
Other mistake: The scene in which Tayo's wife gets into her car to leave their home is filled with mistakes. First off, it seems to take her much too long for the short driveway to reach the curb. Then, when she is blocked by the perp's van, she rams one of the perps twice and then backs away. As she is backing away, the perp's body flies forward, smashing into the van. She then rams the van twice with great force, and yet her car has minimal damage, only to the corner of the car.
Trojan Horst - S1-E4
Continuity mistake: At 38 minutes, Mary and Marshall drive off in a flatbed-style pickup. Twenty seconds later, they're in an SUV.
Factual error: When Tom is locked up in an institution for the mentally ill, he is given a bed on a mixed gender ward/wing (both men and women). Wings and wards in mental institutions have not been mixed gender for more than 100 years - it is inconceivable that this practice would be existing in the 1990s in a large city in the USA.
Factual error: The provincial police is always described as the Ontario Police Department (OPD) instead of the correct Ontario Provincial Police (OPP).
