I can hear the high pitch from your IQ all the way over here.

Rossi [to Reid]

Alfred Austin said "show me your garden and I shall tell you what you are".

Blake

Pregnant victim: What are you doing?
UnSub [exasperated sigh]: Hold still.

Morgan: You're talking to the room, PG.
Garcia: If by "PG" you mean parental guidance strongly advised, I say PA. Prudent advice.

Reid: I don't like the beach.
JJ: Why's that?
Reid: Sandy food, pink skin, limited and unengaging topography. But mostly the drug resistant bacteria spread by seagull feces.
JJ: Sorry I asked.

I became insane, with long intervals of horrible sanity - Edgar Allan Poe

Reid

Wife: Don't worry about me. Worry about those little mice out in your lab.
UnSub: Well I hate to tell you but I've moved up from mice in the last couple of weeks.
Wife: Okay. Whatever critters you have out there I don't wanna know. But if it's a choice between them or the house, well, a couple more might have to give their lives up to science.

J.J.

I'm not doing this for me. I'm doing this for you. Because I cannot let him hurt you, because if he knew.....

Mystery woman

Play on, playah.

Morgan

Blake: What's the deal? Something's not right Spencer.
Reid: What do you mean? Why'd you come back?
Blake: Don't answer a question with a question.
Reid: Look - a while back I had some medical issues. Headaches. And there was a geneticist that I reached out to.
Blake: And this has to with the case...how?
Reid: I think that my friend might be able to help me see something that we missed.
Blake: You have four of the best minds I know back at the station.
Reid: I know but sometimes a different perspective helps me think better, okay?
Blake: Why are you being so ambiguous?
Reid: I don't know what you mean.
Blake: Well you're not using words like "him" or "her". You're saying things like "they are"..."my friends"....
Reid: So?
Blake: It begs a bigger question. Why did you ask me to bring you here?
Reid [with the telephone ringing]: Can we just talk about this later please?
Blake: No. Why not Morgan or J.J.?
Reid: Alex, please....
Blake: Just answer the question.
Reid: Because I don't want them to know about...her. Okay? It's nothing bad. Just personal.

Mystery woman: I don't know what you look like either.
Reid: Really?
Mystery woman: No. The only intimate side I've seen of you was your brain. When I studied the MRI you sent to me. That's when I said "this is a guy I need to get to know."
