Continuity mistake: In the opening scene where Mike and his kid have a conversation outside a toy store, an explosion comes from the top floor of an apartment building. Just before Mike runs off to go save some of the people from the building, he says "Stay with Bernie" to his kid and Bernie then does this. After he says this and runs off, the kid and Bernie are a good foot away from the toy store. The next shot when Mike shouts "Watch my boy!" to Bernie, the kid and Bernie are a great distance away from the toy store without any time to move. (00:01:20)
Continuity mistake: When Ward is in the apartment in Paris, he begins a fight with two people. At a point during this fight, a couch is knocked over and two cushions fall off the couch. The cushions disappear a few seconds later. (00:04:45)
Continuity mistake: As Mike watches the news in the cafe, he is seen lowering his head just as the shot from the reverse angle ends. From the following shot in front of him, he is seen lowering his head a second time. (00:11:10)
Continuity mistake: When Agent Ward goes onto the aircraft to find Agent Fitz and Agent Simmons having an argument, Simmons put a cup of coffee on the desk. It vanishes from the desk a few seconds after she does this. (00:15:40)
Continuity mistake: In the interrogation room, Skye asks "The truth. What are you after?" and Agent Ward replies "World peace." A few seconds after this line, the light on Skye's head and hair keeps appearing/disappearing/changes position. (00:22:25)
Continuity mistake: After the interrogation, Skye tells Agent Coulson about Agent Ward. Coulson says during this scene,"It's a magical place" and Skye says "Ward doesn't like your style. Kinda think I do." At The End of this line, Skye is looking at Coulson. In the next shot, she's suddenly looking 90 degrees in the opposite direction. (00:26:55)
Audio problem: Coulson is talking to a cowboy who sold a piece of construction equipment to some bad people. The cowboy pulls a breach-loader shotgun. Ward grabs the weapon and pulls the cowboy off his horse. Next the distinct sound of racking a shell into the breach of a magazine-fed shotgun can be heard, but the breach-loader is seen.
Continuity mistake: When Simmons is scanning the tree, first she holds the scanner vertically, then the shot changes and instantly she is holding it horizontally. (00:07:50)
Continuity mistake: When the Asgardian bends the knife, he bends the tip up at the very end. When he takes his hand off the knife, the entire front half of the knife is straight. The shot changes again and the knife is bent differently again. (00:24:15)
The Bridge - S1-E10
Revealing mistake: Agent Coulson turns the steering wheel several times despite the car being on a straight street.
Continuity mistake: When Jemma, Skye, and Ward are at the Academy it is daytime. When Seth and Donnie are in the parking garage it is night time briefly. Then, it becomes daytime when they flash back to Ward, and remains daytime when they flash to Seth and Donnie.
Other mistake: Sky's dress has no bullet holes, although she was shot twice in the stomach.
Continuity mistake: In the scene when Coulson is using a diagram to explain to The Team that Cybertek is the common denominator of everything that's happened during the season, he starts tracing lines that connect various bubbles of the diagram to each other, ending with one that links "the bus" to "GH-325." In the next few shots that last segment suddenly disappears, only to reappear later on. (00:04:15)
Factual error: The image of Faro Portugal seen in episode 10 of season 2 is actually an image of "Ponta Delgada", a city on an island several hundred miles away.
Factual error: When Lance Hunter is about to be captured by the military at the beginning of the episode, the troops arrive in a convoy of humvees. The humvees all have Virginia license plates on them, but U.S. Military tactical vehicles do not use license plates. Even if we assume they were using Hummer H1s instead of tactical humvees (commonly used as a substitute on TV and in movies when producers can't get military humvees), military-owned non-tactical vehicles do use license plates, but they don't use state license plates as seen here. Instead, they use official U.S. Government license plates like the ones on the Ford sedan Hunter was dropped off from prior to meeting General Talbot. (00:01:55)
Purpose in the Machine - S3-E2
Factual error: When examining the sand, Bobbi states "According to carbon dating..." Fitz finishes by saying "It's a billion years older than the earth." However, carbon dating is only good at determining the age of something to about 60,000 years old. The only thing carbon dating could tell about the sand is that it is 60,000 years old or older. It certainly couldn't determine that the sand was 5 billion years old.
Purpose in the Machine - S3-E2
Continuity mistake: When May is sitting on the couch talking to her father, the candles behind them are not lit for a couple of shots. They are lit when they start talking and when they finish.
Character mistake: Lance and May walk into a bar in Massachusetts. As they enter, the camera pans and shows a large banner on the front window. The banner is advertising "game day" food and drinks. In very large letters the banner shows Boston Red Socks. The actual correct spelling is Boston Red Sox. (00:05:45)
Chaos Theory - S3-E7
Revealing mistake: In the shot where Lash hauls Rosalind over the parapet to later drop her, you can see that he is actually lifting a mannequin as its legs very fluidly bend backwards while it is being dragged over. (00:32:00)
Continuity mistake: When the Watchdogs destroy the government facility near the start of the episode, 6 shots of Nitramene are fired onto the building's exterior before it implodes. But moments later when Coulson calls Mack, he (Coulson) is watching the news report of the event, and the 6 shots of Nitramene are nowhere to be seen.
Chosen answer: Coulson believes he was resuscitated then sent to Tahiti to recuperate. "A magical place," he calls it. But in the "Agents of S.H.I.E.L.D." episode "The Magical Place", Coulson, through a mind-reading machine, learns that he was treated by S.H.I.E.L.D. and a fake memory of Tahiti was placed as a "mask" of sorts over the painful memory of the operation, which involved a drug seemingly of alien origin to repair the damage, coupled with a lot of morally dubious surgery.
