Hotch: Who is coming?
Christine: Mr. Scratch. He's already here.

Reid: Huh.
Morgan: What? You see something?
Reid: Encryption's a highly specialized skill set but it's fundamentally a mathematical process, which means the human process sometimes through technique can reveal where you learned it. I think I know where he learned how to do this.
Kate: Where?
Reid: Harvard. Which oddly enough isn't known for its advanced math program but it is known for one particular class. When you're good at math - good enough to get into Harvard - you take a math class called "Math 15". When you're better than that you take "Math 25", but when you're the best, the absolute best, you take "Math 55": Honors Advanced Calculus and Linear Algebra. Graduates are immediately employed by the U.S. Government because they're too dangerous to work anywhere else. More specifically, they're employed at the NSA.

Lewis: Don't cry for her. She was stupid, and wrong. She used to burn sage during the sessions. She said that made it safe to talk about Mr. Scratch. What do you see when you look at me? Do you see Mr. Scratch? You can talk now, I want to know. I want to know what you're feeling.
Hotch: That's my team. They know I'm here. They're going to come looking for me, and if you harm me...
Lewis: What are you talking about? Your phone isn't ringing.
Hotch: It was ringing.
Lewis: No it wasn't. Very interesting.
Hotch: You gave yourself away just now.
Lewis: I did?
Hotch: You slipped up.
Lewis: How do you figure?
Hotch: You have no idea, do you? [laughs] You said that she would burn sage, but how would you know that, unless she questioned you too. I know, Peter. I know how those interviews worked, how coercive they were, with children who were innocent and helpless. She questioned you about your father, and she wouldn't stop until she got the answers she wanted. So you gave them to her.
Lewis: Shut up. Oh that was good. Oh that was so good. That was so impressive, the way you got into my head. It makes me want to know how I get into yours.

Lewis: I win.
Morgan: I don't think so.
Lewis: You have no idea what I did to him. I win.

Reid: He surrendered.
Rossi: Ambulance is on its way.
Hotch: He surrendered? That doesn't make sense.
Rossi: We need to get you looked at.
Hotch: I'm fine.
Rossi: Hey! This is not a suggestion

I am not really good at this, but I am gonna step out of my comfort zone. I don't think I ever really told you how much I appreciate you.

An average New Yorker gets caught on camera almost a thousand times a day just walking the streets. Don't think for one minute big bro isn't harvesting that information.

Barry

I lost someone very close to me. She was murdered. But you know what gets me off the floor? This. The idea of bringing a daughter back home to her mother. I play that over and over in my head until it comes true. That is why I do what I do everyday. By healing you I heal me. My job is to stand up for Missy and so is yours.

Avery

You little schemer.

Donnie

I think she might be concussed because she's being weirdly straightforward.

Felix

I'm sorry, love, but you don't get to sit this one out. None of us do.

Felix

Missy is worth more to you alive than dead. And as long as that is the case we stand a good chance of bringing her home alive.
