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.
Continuity mistake: When the kidnapper is taking the girl out of the basement, she is barefoot as she climbs the ladder; but when Morgan pulls her out of the car, she is wearing sandals with an intricate strapping pattern.
Suggested correction: It's quick, but if you look close you can see the heel strap of her sandals as she takes the first step on the ladder.
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.
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.
Character mistake: When Reid realizes who the unsub is, he asks Hotch if he was introduced as "Doctor" or "Agent". As explained in the pilot (and in every episode since), the team has always introduced Reid as "Doctor", to make sure that the people they meet treat him with respect and don't just see him as a kid.
Suggested correction: I think the reason Reid asks for a clarification is because the unsub knew his name and title when he hadn't been formally introduced because this case was under special circumstances so the team wasn't being formal.
It has nothing to do with being formal. The mistake is saying the team never introduces Reid as "Agent Reid", so there's no reason to for Reid to even ask this question.
I think what they meant was that it would be assumed his title was agent, as he is a part of the FBI, but she addressed him by his correct title without any indication of his title being different to the others, which ultimately suggested that she knew Reid beforehand.
Plot hole: In the scene where The Reaper/George Foyet calls Haley from Marshall Kassmeyer's home he identifies himself as Victor Collins from the Marshall Service. Later in the episode Hotch calls Haley and tells her he needs Jack working the case. Jack comes to the phone and asks him "Is George a bad guy?" Until Hotch called Haley she didn't know Foyet was not a US Marshall named Victor Collins.
Suggested correction: He didn't say George.
Character mistake: Dr. Reid calls Penelope "Kristy" on a phone call.
Suggested correction: He calls her "Garcia."
Factual error: Violet is seen wearing Hood style flip-flops where there is a denim like covering just beyond the sandal straps, but this scene takes place in 2001, 12 years before those shoes were available.
Suggested correction: It actually looks like she is wearing wide leg jeans which cover her feet and shoes giving that illusion.
