Criminal Minds, Season 1

Patrol Guy:
You're one of those FBI guys. A profiler, right? Like, one look at the crime scene you can tell what kind of shampoo a killer uses.

Gideon:
You're a bit skeptical.

Patrol Guy:
Maybe a little.

Gideon':
Your girlfriend thinks you're going to break up with her.

Patrol Guy:
You're kidding, right?

Gideon:
Well, you keep adjusting your necklace. That tells me you're not used to wearing one or somebody else probably bought it for you, bought it recently, and the Chinese symbol on it means "forever yours."

[Later]

Gideon':
You broke up with her. No more necklace.

Patrol Guy:
Yeah, I kinda wanted to date someone else.

Gideon:
What's her name?

Patrol Guy:
Brian

Gideon:
Oh. Well, that's... That's a pretty good reason.
