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)
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.
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.
Magnum Opus - S8-E13
Character mistake: Blake says the unsub must be a universal recipient blood type, AB pos, but they are talking about receiving plasma. The plasma universal recipient is O neg, the opposite of what it is for regular blood transfusions. (00:33:27)
Protection - S10-E22
Continuity mistake: When JJ picks up Lizette Castro in her car to take her to her son, JJ gets Lizette to confess about the man in the pictures. We see JJ stop the car outside In the Dark by some trees before a flashback plays. After the flashback, it looks like the car is in some sort of parking house. (00:14:16 - 00:15:16)
A Real Rain - S1-E17
Factual error: When BAU walks up the stairs on the way into the courthouse the first time, the John Ferraro building in Los Angeles is visible in the background. They are walking up the stairs toward Los Angeles City Hall. The episode takes place in New York.
Other mistake: During the flashbacks, they show Prentiss with the rest of the BAU, but Prentiss didn't join until season two. If it was accurate it would've shown Elle, not Prentiss. (00:19:49 - 00:21:01)
Visible crew/equipment: After the three people at the restaurant patio are shot it cuts to the black screen, and in the next shot as the camera pans over the blood stained table, the red T-mark is visible on the ground in front of Gideon's feet. (00:13:15)
Visible crew/equipment: During the plane interior scene after the opening credits as JJ is walking around handing out documents to the team, you can see a gap in the lighting outside and a crew member's face peeking out from behind the white walls. (00:04:00)
Empty Planet - S2-E8
Other mistake: In Empty Planet where the exploded bus is shown, there is an evidence marker with blood spatters on it. The blood wouldn't be there if the marker was placed after the event had occurred.
Other mistake: When Stephen looks at his phone you can see the phone charging symbol even though the phone he's holding isn't charging. (00:06:53)
