Leverage, Season 2

[last lines:
after the job, Eliot and Sophie talk about Nate]

Eliot:
He's fine. We practically had to beg him to come back, all right? He's not drinking, he's at the top of his game. I gotta be honest with you, I can't even believe we pulled this one off.

Sophie:
Well, that's the problem. He keeps winning. Every time he wins, he believes a little bit more that he can control…life.

Eliot:
It's what gets him through the day.

Sophie:
What happens when he loses? Last time he lost, it broke him. He breaks again, I don't think even we could pick up the pieces.
