Continuity mistake: When Wallace brings the snake home he takes it out of the tank and holds it. Between the constant shot changes the snake's position changes entirely.
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.
Final Shot - S9-E3
Revealing mistake: As Reid explains human reaction time, near the end of it you can see a brunette woman get hit and fall to the ground, she hits ground with the back of her head and then, while supposedly been shot dead, moves her right hand in under her head.
Continuity mistake: In the video of the Chicago robbery they enter the building at 08:27 according to the timecode displayed, but they exit at 15:32. Seven hours is a very long robbery.
Continuity mistake: When the thief tries to steal the truck and the owner is beating him up, the passenger window behind the driver breaks. When his daughter later gets into the truck, very briefly the window is not broken. Then the next shot shows her in the truck, the window is broken again.
The Caller - S9-E10
Continuity mistake: At the beginning, a St Louis couple has reported their son missing. At the FBI briefing, the agents are told that the boy's mother tucked him in at 10:00pm. A few minutes later, we hear the radio call over footage of police at the home, and the dispatcher says "Last seen at 2100." That's 9:00pm, not 10:00pm. (00:03:00 - 00:05:00)
Audio problem: When Tabitha gets home, she takes her boots off and as she walks into the kitchen we hear the soft, padded sound of bare feet; when she closes the fridge and walks to the window, her footsteps indicate she has her boots on again.
Character mistake: When Blake is telling Spencer to keep his eyes on her after being shot she calls him Ethan twice. (00:02:29)
Suggested correction: This is very poignant and deliberate moments in the dialogue. Blake is feeling distraught since Reid pushed Blake out of the way and took the bullet instead of her. Blake calls Reid by her dead son's name, "Ethan," when she tries to keep him alert and shouts, "Ethan, Ethan!" Later in the episode, when Blake takes Reid back to his apartment, she explains that watching Reid when he was hurt touched a nerve. Reid then asks Blake, "Who's Ethan?" and Blake tells Reid all about her son "Ethan" who died when he was 9 years old. Blake then tells Reid that "Ethan" would have been a lot like him. Note, on the jet return flight, Blake texted Hotch her resignation from the BAU, and at the very end she leaves her badge with Reid.
Continuity mistake: While Reid's asleep in the hospital bed, Garcia places four Doctor Who figurines (one Dalek we don't see her place) on the overbed table - two Daleks, Matt Smith's Doctor, and David Tennant's Doctor. In the first shot Garcia's holding Smith's Doctor in her right hand and Tennant's Doctor in her left hand, but in the next shot those two figurines have switched hands.
Visible crew/equipment: When Hotchner, Callahan, JJ, and Rossi surround Frank's car on the private property, just after Callahan sees the leg on the seat, when she opens the passenger side door the reflection of the standing male cameraman/crew member is visible on the surface of the car, between the windows.
Other mistake: The age of the deceased Raymond Leu (35) shown in a death certificate doesn't match up based on year of birth (1948) and year of death (2014).
Continuity mistake: The original plane is a 747, (four engines on the wings, two aisles). The plane that Reid gets the plans for is a 727 tri-jet (three engines on the tail and one aisle, not wide body). The plane in the walk through by Reid is a wide body of some sort, but not a 747 (two aisles with three seats in the middle).
Revealing mistake: When Morgan is typing "Cult named Forever People," his phone is typing it automatically. His fingers aren't even tapping the correct letters. (00:19:45)
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)
Factual error: The flashback shown is from 1978, when Virginia license plates had six characters, however the license plate shown on the car is the current version with seven characters. (00:37:00)
Factual error: Rossi recognizes a "typical Dutch gesture" The suspect hits his forehead with his hand and then moves it towards another person, saying that the person is "crazy" This gesture is German. In the Netherlands we use a different gesture. We point to our forehead with our index finger and then point at the person we think is crazy, with that same finger.
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)
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.
Protection - S10-E22
Continuity mistake: In the final stand off, Daniel fires 16 rounds through the door/wall at the team. We've already been told his gun only holds 14 bullets. Not to mention without reloading he fires a few more bullets shortly afterwards.
Protection - S10-E22
Continuity mistake: The vigilante is on the couch drinking vodka. First shot it's in his right hand then the next shot it's in his left.
