The Doctor, Brannigan and others in “Gridlock”

[annoyed that even with three people in the car, Brannigan and Valerie won't take him to the fast lane] So, we keep on driving.

Yes, we do.

[angrily] FOR HOW LONG?!

Till the journey's end.

[snatches up the communicator; into handset] Mrs Cassini, this is the Doctor. Tell me, how long have you been driving on the motorway?

Oh, we were amongst the first. It's been twenty-three years now.

And in all that time, have you ever seen a police car? [looks menacingly at Brannigan and Valerie as they look at him worriedly. Cassini #1 also looks worried]

[pause] IIII'm...not sure.

Look at your notes. Any police? [Brannigan and Valerie look at each other again, worriedly.]

Er...not as such.

Or an ambulance? Rescue service? Anything official? [Menacingly] Ever?

I can't keep a note of everything!

What if there's no one out there?

[seeing that the Doctor has overstepped the mark; snatches the handset out of the Doctor's hand] Stop it! The Cassinis were doing you a favour! [puts the handset back in its slot]

[darkly] Someone's got to ask, 'cause you might not talk about it, but it's there, in your eyes. What if the traffic jam never stops?

There's a whole city above us, the mighty city stayed up. New New York, they wouldn't just leave us.

[frustrated] In that case, where are they? [looks out the window, then back at Brannigan, who seems to accept defeat] Hmm? [getting darker with every sentence] What if there's no help coming, not ever? What if there's nothing? Just the motorway, and the cars, going round, and round, and round, and round, never stopping, FOREVER?!
