- [Nick has a bag with 12 bottles of water in]
- Nick: Little tip. Never go shopping when you're thirsty.
- Ben Harper: Michael... Michael, you can't go through there.
- Michael Harper: Who says?
- Ben Harper: The sign, It says "For use in an emergency only."
- Michael Harper: Well this is an emergency, I'm bored.
- Ben Harper: No! Michael! Michael...
- Susan Harper: -Let him go.
- Ben Harper: Oh, "Let him go." If he breaks one law, what's to stop someone else from breaking another law? And then the whole edifice comes crumbling down, doesn't it? And you get people running around garrotting each other!
- Susan Harper: Ben, he's only gone through a door.
- Ben Harper: It's The door to anarchy!
- Ben Harper: Oh, for crying out loud!
- Michael Harper: Ben, calm down. It's only been five minutes.
- Nick: That's how it always starts- With five minutes... then ten... then half an hour, then an hour, then two hours... then a month
- Ben Harper: Nick!
- Nick: ...Then two months
- Ben Harper: Nick!
- Nick: [Long pause] Then a year!
- Nick: Almost convincing isn't it? It's a recording... on a loop. There's no driver. He's gone. Out of here at the first sign of trouble. We're all alone.
- Nick: Well, I'm off.
- Susan Harper: Where are you going?
- Nick: To find the toilet.
- Susan Harper: No, Nick. There isn't one.
- Nick: Then I'll start one!... Honestly! No initiative, some people.
- Tube Driver: Hello, me again. I still haven't heard from the line controller and the light is still against us. I'm beginning to think they've forgotten us, or perhaps they just don't care.
- [Deep sigh]
- Tube Driver: Well we should be moving off eventually, but, then again, how long is ''eventually''? Who knows?
- Susan Harper: Know your place. Don't take risks. Don't stick your neck out.
- Ben Harper: Don't kill your wife. Don't dismember her body. Don't bury her under a rugby pitch.
