Revealing mistake: When the unsub is in the house with the mother and her toddler, one of the shots of the toddler is flipped, before he starts crying.
Character mistake: When Morgan looks up Charlie Luvet's car GPS map history, the last address reads "11257 Palmdale Drive," but when Morgan phones Hotchner with the address he says, "11257 Palm Drive."
Other mistake: When it shows Keri's license it says it expires in 2003, but the episode takes place way after that year, considering Katrina had already happened.
Other mistake: At the start, the soon-to-be victim gets off the A train at Spring Street (subway heads south, then Bklyn/Queens) and stands on the west-side platform, facing the southern subway exit, then the unsub comes up from behind him, shoots him and he falls toward the same way that the unsub walks - the southern exit. However, when Hotchner plays the NYPD's surveillance footage, the victim is facing the northern subway exit when the unsub comes up from behind him, shoots, and he falls toward the same way that the unsub walks - this time the northern subway exit. Interestingly, neither are flipped shots since we can see "Spring St" correctly. Later, when Prentiss reviews footage it's as it was shown originally.
Factual error: Morgan is following a suspect into the subway tunnels. As he is coming around a corner, you can see the tracks behind Morgan. The tracks are three straight pieces of track making a corner. There is no way a train can make a corner on straight tracks. There should have been curved tracks.
Other mistake: At the start, it's nighttime when the unsub hides in the house of the soon-to-be victim who goes to sleep when her alarm clock reads 'Tue 11:06', and then we see the time morph to 'Tue 1:13' when the victim is sound asleep, before the unsub comes out of the closet to kill her. However, the time on the clock should actually read 'Wed 1:13'.
Continuity mistake: There's a clock on the first victim's night stand. When she goes to bed, it's Tuesday, 11:06. When the murder happens a couple of hours later, it's still Tuesday, 1:13.
Character mistake: When Reid is visiting his mother, playing Scrabble, he has eight tiles on his rack (ROLOAWAD), but a player can only have seven tiles at a time.
Continuity mistake: When Reid is talking there's a big crack at the top of the window that might be a problem since they're supposed to be flying. Then a few seconds later they cut back to him and it's filled with putty. (00:05:00 - 00:06:00)
Other mistake: Evergreen State University in Olympia Washington should be The Evergreen State College (they aren't a university). The transcript for Evergreen (assuming they meant the real college) is also wrong in every way: -They said the guy Ivan was expelled, but the transcript lists a B.A. awarded in June of 1968? - Evergreen has always used a narrative evaluation so there are no grades. There shouldn't be numbers or averages. -There are no majors - you get a B.A. or a B.S. -They don't have classic course names like "Philosophy 101" or "History." -The school was founded in 1967 - he couldn't have taken those classes that are listed from 1964 - 1967. (00:18:50)
Visible crew/equipment: After Prentiss and Morgan catch Eric and his girlfriend in the park it cuts to Prentiss and the girlfriend in the interrogation room, and as the camera tracks backward from the door's window we can see a nice reflection of the moving camera and also a crew member standing behind Hotchner.
Continuity mistake: When Rossi is in Zoe's bedroom the camera pans the room and we see the laptop on the desk with nothing on its lid, but in the closeup suddenly there's a large embroidered flower sticker on the laptop's lid, which vanishes again when Rossi lifts the lid.
Demonology - S4-E17
Other mistake: Prentiss pulls up to a bar and the shot shows her looking out of the car window. "BAR" is shown reflected in red on the car window, but it is readable from left to right under the closeup of Prentiss's face when we see her. The reflection of "BAR" should have been backwards since it's a reflection of the sign on the building.
Audio problem: When Garcia is talking about the cross-examination she's done and how she should be praised for how quickly she'd done it, she crosses the room away from the computers (and the webcam she's shown through) to a bulletin board. While she's walking away, her voice gets fainter, and then becomes louder again when she returns, as though she were getting further and then closer again to a microphone. However, she is wearing a headset with a microphone - the volume wouldn't have changed. (00:13:15)
Visible crew/equipment: After the press conference, while Emily, Rossi, and Derek are standing beside the SUV, when Captain Lancaster walks over to them we can see the four chalk T-marks on the ground where they all stand.
Other mistake: When Morgan calls Garcia to have her search for Vincent, Prentiss jumps in saying he is a mentor. However Morgan had just learned this and didn't mention it on the call.
Continuity mistake: While George Foyet is stabbing Agent Hotchner, the knife is extending from the handle. The blood is at the top of the blade, and as he removes it, the blood moves to the bottom of the blade, while the top remains clean.
Revealing mistake: When showing the corpse's neck where the puncture marks are, you can see her pulse. (00:16:38)
Plot hole: In the scene where The Reaper/George Foyet calls Haley from Marshall Kassmeyer's home he identifies himself as Victor Collins from the Marshall Service. Later in the episode Hotch calls Haley and tells her he needs Jack working the case. Jack comes to the phone and asks him "Is George a bad guy?" Until Hotch called Haley she didn't know Foyet was not a US Marshall named Victor Collins.
Suggested correction: He didn't say George.
Continuity mistake: In the scene where the unsub is having a tea party with her "dolls", look at the diabetic woman's right hand when the unsub is pouring her tea. When the tea is being poured the doll's right hand is palm up. When the camera cuts to a close up of the cup the doll's hand is face down. The doll is paralyzed due to the drugs and had not regained control of her body yet, making it impossible for her to move the hand on her own.
