Eddie Cibrian (who played Joe Smith) and Yvonne Jung (Claire) worked together previously on Third Watch.
The episode was the first time that Dr. Spencer Reid drove his car, a vintage Volvo.
Prentiss: (about the case) How fast can you get us up to speed?
JJ: How fast can you sit down?
Erin Strauss: (stumbling against a fence next to a body at the crime scene) Oh!
Hotchner: (reaching out to assist her) Are you all right?
Erin Strauss: (horrified and shaking) I... I stepped on her hair.
Hotchner: If you need a second, take second. This is what it is. Just don't let the public see you break down.
Morgan: (to Hotchner) Look, man, are you a pain in my ass? Yes, sir! But wantin' to hang out with you, and needin' you to lead this team are two very different things.
Rose: (as Gideon pays his tab at the diner) Where are you headed?
Gideon: Nowhere in particular.
Rose: How will you know when you get there?
Gideon: That's a good question (glancing at her name tag), Rose, that's a very good question.
Prentiss: What could I have told her?
Hotchner: That one of my agents might have murdered a suspect in cold blood. Or another might have a serious drug problem, which I didn't report. And if Strauss had any evidence, my career would be over. I think she put you on our team and expected something in return, and to your credit you quit rather than whisper in her ear.
Prentiss: I told you. I hate politics.
Hotchner: Come to Milwaukee. I'll make you a deal. If your ready bag isn't here, packed, I won't bug you any more. If it is I want you on that plane with me. One more case.
Hotchner: Morgan says you're worried about Gideon.
Reid: I keep on calling him, he doesn't call back.
Hotchner: He's probably at his cabin. That's where he goes when he (pause) needs to get away. Reid, I need your head in this.
Reid: I know.
Erin Strauss: None of you will ever move up the chain of command, you know that.
Hotchner: Why would I ever want to leave the BAU?
Prentiss: (when asked to go to the crime scene) I already turned in my badge and my gun.
Hotchner: That's just hardware.
Morgan: Garcia, baby girl, please tell me something I want to hear.
Garcia: You are a statuesque god of sculpted chocolate thunder.
Morgan: How about something I don't already know?
Garcia: (after an intentional pause) I have a sweet tooth.
Haley Hotchner: Aaron, stop! Don't make me the monster here. I feel sick about these women, but when this case is over there will be another one, and another one, and another one. It is never going to stop.
Hotchner: This is who I am.
Haley Hotchner: No. This is what you do.
Hotchner: I'm trying to do the right thing - here and there - and I would really appreciate a little support.
Haley Hotchner: Oh, that's right, 'cause you always need to be the hero.
Hotchner: Don't give me that.
Haley Hotchner: No, obviously a happy life isn't enough for you.
Gideon: I guess I'm just looking for it again – for the belief I had back in college, the belief I had when I first met Sarah and it all seemed so right. The belief in happy endings.
Morgan: Hotch, we both know that suspension was bogus!
Hotchner: You'll get a new unit chief.
Morgan: What if we don't want a new unit chief?
Hotchner: Well, maybe the next one won't be such a drill sergeant.
Morgan: I'm just glad you're back. Trust me when I tell you things have been a little bit shaky around here.
Hotchner: Morgan, I'm requesting a transfer.
Morgan: Is that a joke?
Hotchner: No, it's not a joke.
Section Chief Erin Strauss: So, do we have a working theory?
Morgan: Sure we do. Somebody really doesn't like women.
Section Chief Erin Strauss: This is your fifth victim, right?
Det. Wolynski: Yes.
Section Chief Erin Strauss: You should have called us sooner.
Det. Wolynski: I thought we had a handle on it.
Section Chief Erin Strauss: Apparently not.
Garcia: (answering phone) Talk dirty to me.
Section Chief Erin Strauss: This is Section Chief Erin Strauss.
Garcia: (horrified and red-faced) Ma'am, I think it goes without saying that I was expecting it to be someone else.
Garcia: (answering phone later) FBI Technical Analyst Penelope Garcia speaking.
Hotchner: George Washington said, "Let your heart feel for the affliction and distress of everyone."

Det. Wolynski mentioned that Milwaukee was known for Happy Days reruns. This series was a situation comedy set in the 1950s-1960s about an idyllic family that lived in Milwaukee, Wisconsin.
Reid: (to Detective Wolynski) You worked the Jeffrey Dahmer case…
Dahmer was a cannibalistic serial killer who was convicted in 1992 of the murder of 15 young men. When Milwaukee police searched his apartment they were horrified to find decomposing bodies and an altar made from human skulls. He was sentenced to 15 consecutive life sentences and was beaten to death in 1994 by a fellow inmate.
