Starring: Thomas Gibson, Matthew Gray Gubler, Shemar Moore, Kirsten Vangsness
Mosley Lane - S5-E16
Character mistake: Reid tells Mrs. Hillridge that he's been working for the BAU about five and a half years, which is roughly since the pilot aired in 2005. But flashbacks in "Tabula Rasa" show that Reid was a relatively new rookie in 2004, which is roughly six years. Considering Reid has an eidetic memory, the six-month discrepancy is a bit suspicious.
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.
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.
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.
