What Happens at Home... - S6-E10
Character mistake: After the murder that takes place while the team is at the church meeting, they gather together to talk about narrowing down the suspect list to the people who didn't show up to the meeting. Spencer shows up with a stack of papers and says 18 suspects didn't show up. We then see his actor break character and almost laughs when he looks over at Ashley, whose actress too almost breaks character from laughing.
Visible crew/equipment: A possible cameraman's hand with a wedding ring holding a bar with the camera is visible as one of the victim looks down a two way route. (00:24:50)
Continuity mistake: In the episode the team is discussing the unsub. He was a man who believed he was Tara's brother. They do not know his name yet. JJ says "He must have put Gabriel's whole life inside of Desmond". Only later does Garcia find out the unsub's name is Desmond Holt. (00:15:22 - 00:18:20)
A Real Rain - S1-E17
Continuity mistake: When Gideon puts on a glove to examine the flint blade from the fourth victim's head, the glove snaps and breaks. In the next shot, more close up, Gideon's glove is not broken.
Protection - S10-E22
Continuity mistake: The old lady victim under the bridge has a change in clothes. When the shooting happens she is wearing a red jumper and what looks like flowery red top, when the team arrives at the crime scene she is wearing a grey jumper and a white polka dot top. (00:15:54 - 00:26:30)
Suggested correction: The change of clothes happens in every crime scene/flashback to show us the killer's delusion. If you pay attention, it happens with the girl whose boyfriend gets killed and also with the cop/mailman.
The Inspired - S9-E2
Plot hole: At the beginning of the episode, PD let the suspect go (twin 1) because they accidentally arrested him for the crimes that his twin brother (twin 2) committed. Hotchner still wants to question twin 1, but a lawyer threatens Hotchner to not go near the wrongfully accused twin 1. However, in the previous episode, FBI and cops pursued twin 1 and twin 1 didn't pull over. It would be legal for twin 1 to be detained on a reckless driving or eluding the police charge.
Other mistake: The boy says he is doing multiplication and the rest of the class is still on long division. You can not do long division without first learning multiplication.
Other mistake: JJ calls Hotch unsure if she can make direct contact with the unsub, fearing that she will make a mistake. Hotch tells her she will do fine and tells her that they are gathering background information about Flynn, who is the unsub. At this point the team have not yet figured out the identity of the unsub and Hotch should not know his name. (00:27:35)
Character mistake: Morgan asks Reid what track on the CD (Some Kind of Monster by Metallica) would help an insomniac sleep. Reid replies with "Enter Sandman" however, Some Kind of Monster doesn't feature the song Enter Sandman. (00:29:00)
Suggested correction: Morgan doesn't ask what song on that album would speak to an insomniac, he asks what Metallica song in general would. He says, and I quote, "Okay, so I'm an insomniac who listens to Metallica to get to sleep. What song could possibly speak to me?" His query is in regards to the band's discography as a whole; neither he nor Reid mention a specific album, so the fact that "Some Kind of Monster" is the CD that they find is, ultimately, irrelevant.
The team was looking for what CD Slessman listened to the most to figure out what his password could be. They had no luck going through all his metal collection. The clue was suppose to be Slessman listened to "Some Kind of Monster" CD the most to help him sleep, which is why it wasn't in the case.
Revealing mistake: When showing the corpse's neck where the puncture marks are, you can see her pulse. (00:16:38)
Perennials - S8-E11
Deliberate mistake: In the outside shot of the unsub's motel in Pensacola, Florida, the sky is black as if someone behind the scenes tried to digitally remove part of the background in post, but did a really bad job.
There's No Place Like Home - S7-E7
Character mistake: On Travis James' arrest report it shows his DOB as 10/28/98 and Garcia says he is 22. This show is based in 2011 at this point so the DOB should be 10/28/89.
Visible crew/equipment: A crewman's left hand (with wedding ring) on a black metal railing is visible on the left side of the shot of the woman at the corridor intersection. (00:24:57)
Visible crew/equipment: As Rossi comes to Morgan's rescue you can see a guy behind Agent Rossi seemingly holding a camera. A few seconds later Morgan gets up and right before he turns to punch the henchman guy you see the same camera guy again. (00:34:33)
The Fisher King: Part 1 - S1-E22
Visible crew/equipment: When Elle arrives back at her home the camera pans and you can see the face of a man in the mirror. A man who is not the Fischer King as he has no facial burn marks on him. Potentially simply a stand-in for the character or the actor without the makeup as when the Fischer King is going to shoot Elle you cannot see his face.
Visible crew/equipment: When the team enters the house of the unsub it is dark. You can see a second camera man twice off to the side who is getting the close ups of the team coming through the door. (00:32:00)
Other mistake: In the opening scene, the car has a Florida license plate visible on the front. Vehicles registered in Florida (and eighteen other states) don't have plates on the front.
Character mistake: When they are delivering the profile, Rossi says "he's already picked his next victim; an adolescent boy." The victim is a girl.
Suggested correction: Rossi is talking about the next victim after the girl.
Other mistake: When Hotch, Morgan and JJ review the footage from the first murder, they are able to zoom extremely close on the victim's hand. Why don't they do the same with the car license plate as the killer leaves? (00:21:45)
