The Shadow Line2011

Peter Glickman:
Controller. It's not just a name to you, is it? It's what you have to have, no matter what. But there must have been a while back there, after I disappeared, when even you thought you'd lost it.

Gatehouse:
Knew I'd get it back.

Peter Glickman:
And that's why you didn't kill me at the door, isn't it? Because getting it back is what you wanted me to see. How are you going to do it, James? I'm guessing not with a gun - far too noisy. But your own hands? You must be angry. And to think, if I hadn't left that phone signal, you wouldn't be here.

Gatehouse:
But you did... and I am.

Peter Glickman:
You followed the trail.

Gatehouse:
The one you left.

Peter Glickman:
But what if I knew you couldn't help but follow it? May I? [Glickman sits down, almost shivering with anticipation] The only person who could force my son into leaving a message on that phone was you. I knew that. And I knew that once I picked it up, you'd follow the signal. And because you thought you'd found it, it would never occur to you that... actually, you were being led. Because it's who you are, what you do. Control, at any cost. Any cost. Ironic, then, isn't it? That by coming all this way to get it back, you lost it all together. Human, after all.
