Berlin, 1989. Not a good year for building walls in East Germany. We had just won the Cold War. I was off to Moscow, a new assignment. Diane was on her way back to Washington and a promotion. We wouldn’t see each other for months. And just before I left… she asked the question. “What about us?” That’s when I said it. I’m not even sure why. I told her, if we’re alive in 20 years, let’s throw in the towel. Be a normal couple, lead a normal life.

Roan: Because I’m not in love with one of the agents.
Chuck: I’m not… I care about them. I care about *both* of them. Besides we both heard what she said, okay? To her, I’m just an asset.
Roan: No. You’re not… Trust me. The lady doth protest too much. But i want to ask you something: she is worth dying for?
Chuck: Yes.
