You're the reason he's the most prolific serial killer I've ever seen.

Rossi

Morgan: When Joe got mad, was he always out of control? What did he do to you? I need the details, Daria.
Daria: He'd punch us so hard we couldn't see for a week. He'd tie us to the radiator. God, I hated that radiator.

Agent Prentiss knows this, but I have followed and admired the work of the BAU for years. So when Emily called and asked me to join the team, the answer was easy.

Walker

You're a bad liar, just like Mom.

Desi; Are you afraid of me, Tina? Tina; No, I'm not afraid of you. Desi

Eyewitnesses are notoriously unreliable, especially in situations like this.

Prentiss [to Alvez]

JJ: Hey Garcia.
Garcia: I was starting to feel like the hottest people I know had left me at the altar, but now you're here to kiss me with crime. What's up?

I gotta be honest with you. There's a real side of me that's saying, "You go, girl." You're the one who brought him into the world. Yeah, you should be the one to take him out of it.

J.J. [to Roberta]

Morgan: Daria, when you ran weren't you afraid they might find you?
Daria: Yes. But I was hoping someone else might find me first. Where were you?
Morgan: We were on our way.

Here I am, Mom. And you were right. I am a monster.

Desi [to Laura]

Hotch: Yes, they did talk to me about the Section Chief job.
Reid: Do you want it?
Hotch: I know what I don't want is an outsider coming in and questioning every move that this team makes. I told them that I'd think about it.

Unsub: Are you ready for phase two?
Danielle: Are you going to keep hurting me?
Unsub: No. Never. Never again. Never again. [He begins unwrapping her bandages.] It's okay. Almost there. You're beautiful, Sarah.

Lewis: Look, Doug. These interviews with Ennis, these late nights, this is important work, alright? It's meaningful work. I am trying to take serial killer protocols to the next level.
Fuller: You're more interested in a guy who killed a bunch of little kids than you are in me.
Lewis: I have to be into the office first thing in the morning, so could we talk about this at dinner tomorrow?
Fuller: There's nothing more to talk about. I'm going back to San Francisco.
Lewis: What?
Fuller: My flight leaves tomorrow afternoon.
Lewis: And you're just announcing this?
Fuller: Things haven't been good with us for a while now.
