Spooks, Series 7

Ros:
How's the nervous system?

Lucas:
Twitchy. This is a mistake.

Harry:
[Ros and Harry thinking Lucas is a Russian spy] I'm glad you didn't waste those years trying to memorize convincing excuses.

Ros:
Maybe Kachimov should add that to his curriculum.

Lucas:
We should be following Elizabeta.

Ros:
We are following Elizabeta.

Harry:
Come on, Lucas. Impress me with your ability to talk your way out of this.

Lucas:
I agreed to be Kachimov's agent in London. Of course I did. But just to get back. To come home. God knows I couldn't rely on you to do it for me.

Ros:
And you failed to mention this earlier. Why?

Lucas:
[to Harry] I told you in the car.

Harry:
You joked about it in the car.

Lucas:
You suspected it. You as good as told me. If I admitted it officially, you'd lock me in a call and debrief me for months. I've seen enough cells.
