[As V, disguised as William Rookwood, is found by Finch]

V:
[puts out a hand] That's close enough, inspector. [activates a debugger]

Finch:
We're not wired.

V:
I'm sorry, but a man in my position survives by taking every precaution.

Finch:
You've information for us?

V:
No, you already have the information. All the names and dates are inside your head. What you want, what you really need, is a story.

Finch:
A story can be true or false.

V:
I leave such judgments to you, inspector.

[Later on]

Finch:
Can you prove any of this?

V:
Why do you think I'm still alive?

Finch:
Right. We'd like to take you into protective custody, Mr Rookwood.

V:
Oh, I'm sure you would. But if you want that recording, you'll do what I tell you to do. Put Creedy under 24-hour surveillance. When I feel safe that he can't pick his nose without you knowing, I'll contact you again. Until then, cheerio.

Finch:
Rookwood. Why didn't you come forward before? What were you waiting for?

V:
Well, for you, inspector. I needed you.
