Lie to Me, Season 1

Cal Lightman:
You know, I wanted to--

Ria Torres:
Yeah, I know. Thanks.

Cal Lightman:
What?

Ria Torres:
You had a slight gratitude smile. What you're surprised? Really? You know, just because I don't know your science, doesn't mean I don't know things.

Cal Lightman:
You know, when you don't know the science, you don't see the whole picture. People can get hurt.

Ria Torres:
(Reacts to an expression the audience can't see) What was that? What happened?

Cal Lightman:
What?

Ria Torres:
Shame. When you said 'people get hurt,' you showed shame.

Cal Lightman:
(Keeping his face neutral) I don't know what you're talking about.

Ria Torres:
You're lying.

Cal Lightman:
Get used to it.
