Lie to Me, Season 1

Cal Lightman:
I'm sorry about before. (Ria raises her eyebrows at him) Sometimes I see so much, I don't know how not to tell people.

Ria Torres:
Yeah, I get that.

Cal Lightman:
You're right; most people don't change. Right? I've been there, waiting for it, hoping for it, and then they just... don't.

(Ria takes an unsteady breath.)

Cal Lightman:
But there are a few, I think, who can.

Ria Torres:
Any other life lessons?

Cal Lightman:
(leans forward in his chair) When someone... bashes you around, who's twice your size, just whenever he feels like it, you learn to read emotions pretty fast. We adapt to survive. Your abuse made you a natural. He made you what you are.

Ria Torres:
(takes another unsteady breath) Well, I'll be sure to thank him.

(Cal laughs and sits back in his chair)

Ria Torres:
So what about you?

Cal Lightman:
Nah, I'm not a natural. I had to learn this.

Ria Torres:
Why did you want to learn? What, you all of a sudden became obsessed with facial expressions? (she reads his face) I didn't think so. So who was it? Who made you who you are?
