When Will LaMontagne, Sr. is talking to his son, he calls him "Billy." And when the team meets him, he introduces himself as Bill. However, in all future appearances, he is called "Will."
This episode marked the first appearance of Detective William LaMontagne, Jr., who was written in later as the father of Agent "JJ" Jareau's baby (Henry) when the actor herself (A.J. Cook) became pregnant in real life.
Morgan: Are you gonna tell me why you missed that flight to Galveston?
Reid: I already told you, there was no cell reception.
Morgan: Reid, any time you want to come up with a better answer, I'm standing right here.
Det. LaMontagne: (to JJ) How will I ever survive a woman like you going so far away?
JJ: You are the best ever.
Garcia: Aw, and you're the most perceptive.
JJ: You always drink while you're still on the clock?
Det. LaMontagne: This is New Orleans, honey, it's a cultural thing.
Reid: I guess I just needed to try to figure out if I could step away from this job.
Reid: I'll never miss another plane again.
Garcia: What was the thing Jack the Ripper took from one of his victims, besides, well, you know, her life?
Prentiss: Oh! Uh..uh...
Prentiss: (giving up) I don't know.
Garcia: A kidney. How horrifyingly fantastic is that?
Prentiss: Mm... hmm... Are you going anywhere with this?
Gideon: He'll lure with charm and kill with rage.
Prentiss: How could their friends not see anything?
Morgan: It's like when the lion preys upon antelope.
Prentiss: You lost me.
Morgan: Well, that's because you, Emily Prentiss, have never been one of the antelope.
Prentiss: Oh, scratch that. You totally lost me.
Morgan: Okay, check this out. The antelope travel in packs; so the lion just sits and waits. Waits for just one of the antelope to break away from its herd. So when he's alone, vulnerable, and completely unprotected, that's when lioness strikes, that's when she makes her move.
Prentiss: Wait a minute, her move?
Morgan: Prentiss, there's only one thing that's gonna make a straight man leave his friends on guys' night out, and it'll make him leave every time.
JJ: (to Det. LaMontagne) Well, despite what you may have heard, cell phones can be very good for your health.
Ethan: (to Reid) And if I can tell? You're surrounded by some of the best minds in the world. If you think they don't notice Well, for a genius, that's just dumb.
Reid: I've always been one step ahead of you, man.
Ethan: Yeah, whatever helps you sleep at night.
Prentiss: I can still smell the alcohol on him.
Coroner: This is New Orleans. Dead or alive, it's a smell you get used to.
Det. LaMontagne: Why aren't you married?
JJ: Uh, that involves this case how exactly?
Det. LaMontagne: It doesn't. I'm just flirting.
Reid: I missed that plane on purpose.
Gideon: I know.
Reid: I'm struggling.
Gideon: Well, anybody who's been through what you've been through recently would.
Gideon: I have been playing at this job, in one way or another, for almost 30 years. I've felt lost; I've felt great. I have felt scared... sick... insane. I don't know... I guess the day this job stops gnawing at your soul and your hands, your hands stop feeling cold, maybe that's the time to leave.
Gideon: Robert Kennedy once said, "Tragedy is a tool for the living to gain wisdom. Not a guide by which to live."
JJ: I wouldn't follow a stranger into an alley no matter how wasted I was.
Det. LaMontagne: Yeah, but you're not a man. Testosterone will follow a woman to Thailand... barefoot.
Det. LaMontagne: When I first started as a cop, I worked the Quarter. It was like being in the riot squad every night.
Gideon: We believe this killer identifies with Jack The Ripper because he's lost his own identity.
Gideon: The city is barely back to life. Something like this could cripple its psyche.
When this episode originally aired, CBS used it to promote an online contest to win free tickets to the movie Zodiac, which is based on the real-life Zodiac killer. The Zodiac and Jack The Ripper cases are somewhat similar; both killers wrote taunting letters to the police and both cases remain unsolved.
Morgan: The Sante Kimes model cold, calculated, preys on men for money.
Sante Kimes, the other woman serial killer mentioned in the episode, killed for monetary gain rather than revenge. She and her son were convicted of murdering Irene Silverman in 2000. They were also presumed responsible for three previous deaths.
The brief rape scene in this episode in similar to the one in the 1988 movie The Accused. The victim in the movie was Jodie Foster. In both scenes, the assault takes place in a crowded bar, the assailants are cheered on during the assault, and the victim is blamed for provoking her rapists by being intoxicated and behaving in a flirtatious manner. Jodie Foster won an Oscar for her performance in The Accused.
Garcia: (answering the phone) O Captain, my Captain.
"O Captain!, My Captain!" is a Walt Whitman poem written in homage to Abraham Lincoln after his assassination. This poem is in his constantly revised and famous book "Leaves of Grass." Non-literary types will recognize it as the title students used to address Robin Williams' character, John Keating, in the film Dead Poets Society.
Reid: It's more likely we're dealing with the Aileen Wuornos archetype.
Aileen Wuornos was a female serial killer who prostituted herself on highways and killed several of her customers. She was nicknamed the Highway Hooker. She tried to claim the men she killed had raped her and that her actions were in self-defense but she was ultimately convicted and executed. Charlize Theron played Aileen in the movie Monster.
