Trent knocks his drink off the table as he looks around for Megan, and leaves it on the floor after she arrives. Later in the scene, as Megan takes Trent's hand, the glass is back on the table. When they sit drinking the wine, the glass is gone again.
In the opening scene where the unsub is sharing a drink with her second victim, she has two glasses, one is smooth and the other is twisted. She keeps the smooth glass and walks across the room and puts it on the table to answer her cell phone. After she watches her victim die, she picks up the glass, but it is the twisted glass not the smooth one that she had put down.
After Megan Kane searches for "Hotchner" on the internet, the video of the press conference she watches was taken from "Brothers in Arms."
Megan: (to Hotchner) How could your wife have ever left someone like you? You're the first man I ever met who didn't let me down.
Lauren: (to Prentiss and Reid) You two need lessons in faking it. I teach a class.
Reid: What about the, umm, type of work your employees do? We're sort of operating under the assumption that this escort is, umm, killing men who... make her perform a... specific sexual act.
Lauren: What did you have in mind, sweetie?
Reid: I... I don't even... I don't know.
Morgan: (looking through the unsub's closet) Hey, Prentiss... (removes a leather outfit from the closet and holds it in front of Prentiss) ... got a whip?
Reid: Eighteen cars, six houses, and three boats. Can you even boat in Dallas?
Prentiss: Well, when you are talking about that much money, 10 grand for a call girl is like deciding where to go for dinner.
Prentiss: So your age difference was part of the attraction?
Mrs. Yvonne Ashford: Are you kidding? That was our whole relationship.
Hotchner: Garcia, can you generate a list of high-profile Dallas CEOs who are holding out on their ex-wives?
Garcia: Loaded Losers List Dallas Edition, coming at ya.
Megan Kane: Who was it who said, "you don't pay a prostitute for sex, you pay her to leave afterwards?"
Hotchner: It was Dashiell Hammett.
Megan Kane: It doesn't make sense. The men always leave first.
Hotchner: "A prostitute is not, as feminists claim, the victim of men, but rather their conqueror, an outlaw, who controls the sexual channels between nature and culture." Camille Paglia
This is the first episode in which the final quote was incorporated into the storyline directly and delivered by the unsub rather than by one of the team members.
Guest star Catherine Dent and Thomas Gibson worked together previously on Dharma & Greg.
The song heard at the beginning of this episode was "Mercy" by Duffy.
Prentiss: Aileen Wournos used to purposefully stage paid sexual encounters as an excuse to murder men she thought would rape her.
On October 9, 2002, Aileen Carol Wournos was executed by lethal injection in Broward County, Florida, for murdering seven men. She claimed the men picked her up when she was working as a highway prostitute and she shot them in self-defense after they attempted to sexually assault her. Her story was told in a film titled Monster (2003), in which Charlize Theron won an Academy Award.
