Revealing mistake: When Agent Hotchner receives a text from JJ while interviewing the suspect, it is actually a screenshot. You can see Camera Roll in the upper left hand corner, "2 of 2" where JJ's name should be, and the Share/Play/Delete banner at the bottom. It is covered by Agent Hotchner quickly tapping on the screen to clear the banners. (00:16:15)

Criminal Minds (2005)
1 revealing mistake in season 8 - chronological order
Starring: Thomas Gibson, Matthew Gray Gubler, Shemar Moore, Kirsten Vangsness
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'.
Agent Hotchner: This is Special Agent Dr. Reid.
Man: You look too young to have gone to medical school.
Agent Reid: They are PhD's. Three of them.
Man: What, are you a genius or something?
Agent Reid: I don't believe that intelligence can be accurately quantified, but I do have an IQ of 187, an eidetic memory, can read 20,000 words per minute...yes, I'm a genius.
Trivia: Dr. Spencer Reid is the son of an attorney, born in Las Vegas. In real life, Matthew Gray Gubler, the actor who plays Reid, is also the son of an attorney, born in Las Vegas.





Chosen answer: Back in Target Rich, a hitman named Giuseppe Montolo dies whilst being interrogated by Derek. The men who abducted Derek were hired by his father, Chazz, who seems to blame Derek for his son's death. It's explained further in A Beautiful Disaster.
