Callen: I think he's going to be difficult to find Hetty.
Hetty: Oh, you don't say?

Arkady may have been Callen's last chance of finding out who his father was and where he came from.

I've been watching you, you have great potential. And I have plans for you, Mr. Callen.

Hetty: Well, intelligence only takes us so far.
Nell: Why is that?
Hetty: We're human.

Hetty: She just hung up on me!
Beal: Rough call, wanna talk about it?
Hetty: No I don't Mr. Beal.

The spy game has more in common with selling used cars than we'd like to admit.

Hetty: Michelle is very strong, Owen.
Granger: Agreed, but she's not the one I was talking about.

Deeks: Oh come on Hetty, I know Mexico! I've surfed all around that country.
Hetty: Oh, so have I.

Pull out Mr. Callen - that's an order.

Hetty: You Grinch, I know there's a heart in there somewhere.
Owen: You're right, I'm just not telling you were it is.

Do you think you could last a week?

I may just drop you into general population at Twin Towers prison.
