Bailey: The Attorney General has granted me full authority in this matter.
Elias: Of course. Because by math, there's only two people who know about it.
Bailey: Only you and me. [he gets a bullet between the eyes]

Garcia: Oh my God. What if they both die?
Luke: Penelope, I don't know. Maybe if we lean on each other, we'll have the strength to get through this together.

So, you would rather kill us than have us learn that you were a serial killer?

Sydney

Rossi: It's my time.
Krystall: Yes, David. It's your time to live.

Sydney: I came here to ask you where is Agent Rossi? He tried to save our family.
Elias: He doesn't matter.
Sydney: Does 15 years matter? Two children matter? All those days and nights together? How do you expect me to believe one moment of that was real, that you had genuine love for me, for Holly, for Harlow? Show me that you're capable of real feeling. Show me that you're not just some sociopath that can mimic human emotions. That our marriage was more than just some elaborate alibi. Tell me, where is David Rossi?

Man cannot possess anything as long as he fears death, but to him who does not fear it, everything belongs. -- Leo Tolstoy

Rossi

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

Rossi

That's not our only problem. When Voit wants to go underground, he does. Literally.

Prentiss

Rossi: You've had intrusive thoughts about murdering them ever since Cryus, haven't you? Ohhh. That's a yes. There's a term for what you're going through. It's called devolution.
Elias: Yes, I know what devolution is.
Rossi: Then you know it never ends well.

Prentiss: Are you positive Elias Voit is Sicarius? It will be a heavy lift to reopen the investigation.
Rossi: No, I'm not positive, but the wife recognized him from the footage, and she's a spitting image of Sicarius's last victim, Ramona.

When it comes to profiling, your team's the best. It's how you prove it that's the problem.

Rebecca

The Latin phrase Memento Mori translates to Remember that you must die. Roman slaves whispered it to their generals to keep them from being consumed by hubris.
