On the unsub's juvenile record, the geographic information is inaccurate. There is, in fact, a Hyde Lane in Maryland; however, it is located in Bowie. The ZIP code listed with the address is 21235, which is the ZIP code for Woodlawn, a neighborhood in Baltimore. Woodlawn and Bowie are approximately 50 miles apart.
When the team enters Jimmy's apartment and Morgan breaks the wall and finds the gun, he handles both the clip and the gun without wearing any gloves. By doing that, he compromised potential evidence.
It is revealed in this episode that Morgan once had an undercover assignment for 18 months.
Gideon: We have a word for you.
Vincent Perotta: You got a word for me?
Gideon: Oh yeah. Actually, we have a few. Psychopath. Paranoid personality disorder.
Vincent Perotta: That's quite a mouthful, Jason.
Elle: (talking about Garcia's ability to find criminal records) Can you get into those records?
Reid: Despite the fact that they were probably expunged, she can find the faintest echo of deletion, and successfully recreate the file thereby sending us all to prison for computer felony fraud counts.
Elle: We can make bail.
Garcia: You're breathing on my neck.
Reid: I'm sorry. Sorry.
Elle: You two having fun?
Garcia: Oh, yeah. Sifting through the life and times of Freddy Condore with Dr. Reid here is a party I wouldn't want to miss.
Gideon: (after revealing photos of murdered people on board) I believe you're an extremely impotent man.
Vincent Perotta: (rattling his handcuffs) Take these off - we'll see!
Hotchner: Paranoid personalities develop in childhood.
Vincent Perotta: You know, you just saved me thousands of dollars in therapy bills.
Hotchner: But your father beat you every chance he got.
Vincent Perotta: He smacked me around some. Didn't everybody's old man?
Vincent Perotta: Well, maybe if yours had, you would have learned to fight.
Hotchner: You were just responding to what you learned, Vincent. When you grow up in an environment like that, an extremely abusive, violent household, it's not surprising that some people grow up to become killers.
Vincent Perotta: Some people?
Hotchner: What's that?
Vincent Perotta: You said some people grow up to become killers.
Hotchner: And some people grow up to catch them.
Morgan: (Garcia enters the room holding a cardboard box) Please tell me you brought some breakfast.
Garcia: Huh? Trust me, sugar, you're not going to want to eat when you see what's in here.
Gideon: Hemingway wrote, "There is no hunting like the hunting of a man, and those who have hunted armed men long enough and liked it, never really care for anything else."
Gideon: Carl Jung said, "The healthy man does not torture others. Generally, it is the tortured who turn into torturers."
When the neighbor comes over to complain about the loud music, the song that is playing is Let's Do It (Let's Fall in Love) sung by James Darren.
Garcia: We're gonna need a bigger board.
A reference to the famous line from the movie Jaws as the shark appears and Brody announces, "You're gonna need a bigger boat."
Morgan: John Wayne Gacy killed at least 30 people.
Thirty-three, actually. John Wayne Gacy lived in Chicago. Gacy was known as a family man and a successful businessman who was active in community organizations, but he was also a pedophile who killed young men and buried them under his house. He was executed in 1994. People used to call him the Killer Clown because before his arrest he used to dress up as a clown and entertain children. Also while he was on death row he liked to paint clowns.
The episode's title refers to Oliver Stone's 1994 film Natural Born Killers.
