You're an amazing genius of a man who's also extremely cute.

Nell [to Eric]

Jane: I thought [Hetty's] been AWOL for months.
Callen: She still is.
Jane: Then how the hell does she know what we're doing here?
Sam: Behold the many mysteries of Hetty.

Darius: I have an idea. It might get messy.
Sam: Messy works.

As a lawyer, I am floored by your grasp of the legal system.

Deeks [to Conklin]

Deeks [to Rountree]: You do realize that I'm a detective, right?
Kensi: Actually, we're both detectives, babe.
Deeks: See? Nothing gets by us.

Deeks: You think [Eric's] up for it?
Hetty: Well, what's the worst that could happen?

I love happy endings.

Deeks

It's a knock. Learn how to do that.

Kilbride [to Roundtree]

Inspector: Do the mother and son hate each other?
Roberta: They're starting to.

Hetty: Second unrelated question, do you have plans for this weekend?
Nate: Plans?
Hetty: Plans.
Nate: Uh, are you asking me out? No, that'd be weird. No, no plans.

Well, I don't see a lot of movies.

Long

Kilbride: I know this is not my place, Agent Rountree. But it might not get better, even if you do push. Crooked cops have gotten less for doing worse.
Rountree: Much worse.
