Continuity mistake: When Vincent is showing the delivery man his basement to show him the wooden cube isn't there, the delivery man's ID tag is positioned so that the front side is facing outwards. In the next shot, the ID tag has suddenly flipped around. (00:11:20)
Other mistake: The extent to which the classmates wrapped Miles in cellophane with his hands folded in front of his groin would make it difficult, if not impossible, for Miles to get out of the lake alive on his own. Miles did not drown... or suffer any injuries.
Factual error: When Jane is putting up the lost poster, the number to call is 1-800-saw-him. However, this is only a 6-digit phone number when it needs to be 7-digits (not including the 1-800 part).
Continuity mistake: When Will Parry visits his grandparents, the grandmother is sitting on the sofa next to Will's grandfather. The grandmother's position keeps changing from sitting right next to him to being further apart.
Chaos Is the New Cocaine - S1-E3
Continuity mistake: Alex opens a bottle of wine. She takes the cork off the corkscrew with both hands and the bottle of wine spins from not showing the label to showing it. (00:37:55)
Continuity mistake: When Nick's mom tells him to show Gypsy around she takes the cigarette away from her lips. A shot later it's back in.
Visible crew/equipment: When Michael Fay (1st Vampire ground zero) enters the cabin to escape the police, the film crew can be seen through the porch railing at the bottom right of the screen. (00:40:53 - 00:49:47)
Continuity mistake: Detective Hoffman is in Grey's bar when Grey serves him a drink with a cherry on a skewer. The cherry alternates between being down in the drink or up leaning on the rim of the glass.
Factual error: Almost none of the senior police officers wear the correct medal ribbons. Brian Moore and Pat Geenty wear the Order of the British Empire, which neither had. Geenty wears the General Service Medal, for military service in Northern Ireland, although he was never in the armed forces. Moore does not wear the Queen's Police Medal, which he was awarded in 2009. Both wear the Diamond Jubilee Medal in 2011, although it was not awarded until 2012. Andy Parker wears an unidentified ribbon (possibly intended to be the Queen's Police Medal, which he was awarded in 2010, but looking nothing like it) and the Golden Jubilee Medal, but does not wear the Diamond Jubilee Medal or the Police Long Service and Good Conduct Medal to which he was also entitled. Mike Veale and Ray Hayward wear no medal ribbons at all, although both would be entitled to the Golden Jubilee Medal and Police Long Service and Good Conduct Medal (and Veale also to the Diamond Jubilee Medal after 2012).
Picture's Up - S1-E5
Continuity mistake: When the detective goes to retrieve the water bottle that Zach discards into the recycle bin, he picks it up with a napkin by the top. In the next shot, he is placing the bottle in a plastic bag top first, holding the bottle with the napkin by the bottom. (00:42:00)
Continuity mistake: The mayor Bobby and Keri are talking in a restaurant. Flashback 5 years - the same man sits at two different tables in two different sequences. (00:13:35)
Most Likely to Go Your Way (And I'll Go Mine) - S1-E5
Continuity mistake: A group of people are standing before a door with full glass inserts. It has a thought processor for access. Once the group defeats the processor, they open the doors. But the doors are now solid wood, not with a glass insert. (00:29:20)
Deliberate mistake: In the restaurant after their daughter finishes talking to Niko, Erik turns the tablet device around and sets it on the table to talk to Niko. From his perspective, he is looking down at the screen. But in the other shots from Niko's perspective, where he is a life sized hologram, his figure is shown looking up and meeting her eyes. But from her perspective it should look like he's looking down at the table.
Character mistake: At the police station when Damien Asante is reading the information on the computer about the hit and run, he says "On February 25, 2015 Christy Markus and her son were struck by a car. The driver kept going." If you look at the computer screen, the date of incident says February 25, 2018. (00:30:00)
Continuity mistake: Captain Dobbins has her Garrison cover tucked under the belt of her uniform overcoat with her rank insignia not displayed. In the next shots, the USMC emblem is displayed on her Garrison cover and rank insignia is displayed again. (00:25:05)
