This is Prentiss' first appearance since the episode "200."
The episode has no opening or closing quote.
This is one of the few times an episode didn't begin with a quote.
Goof: When Reid and Morgan are interviewing Kyle, he tells them that he sent a message to Page with Internet Relay Chat. Morgan says, "IRC self-deletes when you close the window," and Kyle agrees.
Morgan and Kyle are not correct. Many IRC clients log activity by default, and IRC servers can also be configured to record chats.
When Duke and Tammy are standing next to the fuel tank, chatting about Cole needing his father, Duke's left sleeve is rolled all the way down. The scene cuts to an alternate angle and now it's rolled up to his elbow.
The opening quote told by Hotchener is similar to a quotation by Reid in the season four episode "Conflicted."
This is the third episode where the BAU has gone to another country to investigate a case. The first time was in the episode "Machismo," where the team went to Mexico, and the second time was in the two part episodes "To Hell" and "...And Back," where the team went to Canada.
The song heard during the closing montage is "Ancient Light" by Allman Brown.
Det. Rosenburg: (about Garcia) She has our entire I.T. department tasked with trying to take the picture down off the web. So like you probably already know...
Morgan: Well, the internet is forever.
A callback to the season five episode, "The Internet Is Forever".
Goof: Reid mentions the "Battle of Saint Scholastica Day" saying it occurred in 1335 and lasted two days. In reality the "St. Scholastica Day Riot" occurred on February 10, 1355 and did (indeed) last two days. In 1335 various scholars left Oxford, as they felt the city was unacceptable for various reasons, including the heat. The two day riot, though, wasn't until 1355. While this could be a simple typo, the real SSA Reid wouldn't make such a goof (thus a double goof).
This episode is partly based on the Malaysia Airlines MH17 crash. Malayasia Airlines MH17 was shot down over Ukrainian airspace on July 17, 2014, killing all 298 souls on board.
When delivering the profile of the killer(s), Dr. Reid refers to Paul Bernardo and Karla Homolka (Canada's Ken and Barbie killers) stating they "raped, tortured and killed at least nineteen people". This is incorrect, as Bernardo and Homolka were connected to only three deaths.
Tahmoh Penikett calls for "Helo" extraction when the BAU team breaches the perimeter. Tahmoh Penikett played Captain Karl Agathon code name "Helo" on the new Battlestar Galactica.
Garcia says Andy's parents put him to bed at 10:00pm the night he disappeared, but the policeman on the radio says he was last seen at 2100 hours, which would be 9:00pm.
The local pervert that was hung at a tree was pushed off a stoop and immediately broke his neck. He wasn't pushed hard enough, nor from a sharp enough angle for his neck to have broken.
Garcia is the only one aware of the fact that Hotch's birthday is right after Halloween/Day of the Dead. When Hotch arrives for her party, Garcia says "Happy almost borthday. I'll keep it on the DL."
Garcia says she's never had the whole team at her apartment before. While she's never invited the whole team over before, the whole team was in her apartment after she was shot in "Penelope."
Normally Dr. Reed wears Converse Jack Purcell low top sneakers. While reading on the floor in the Sheriff's office, we see he is wearing Converse Chuck Taylor All Star low top black sneakers.
The license plate on the car that drove Hotch to the theatre in his dream was '509 905'. That's probably in reference to the episode where he killed George Foyet (season 5 episode 09) and this episode (season 9 episode 05).
The shot of Rossi and JJ watching the unsub's video on his tablet shows Rossi holding the tablet at portrait orientation, but the shot of the video on the tablet shows him holding it at landscape orientation.
