CSI: NY, Season 7

Jo Danville [to Torrey Powell]:
You swallow a lot. I mean a lot a lot. I don't mean to make you feel self-conscious. It's a common OCD anxiety disorder. And I would recommend exercise or some kind of organized sports to keep your mind focused on something else. But since those really aren't an option now, you're kinda screwed. Unless...

Torrey Powell:
Unless what?

Jo Danville:
Well, the sympathetic nervous system is responsible for your body's reaction to stress and right now, there's no question you're under a great deal of that. So you're gonna need to really figure out how to alleviate that somehow.

Don Flack:
How about by telling us the truth, Torrey?

Jo Danville:
It's a matter of your personal safety.

Torrey Powell:
What the hell kinda mind games are you playing, lady?
