Daleks: Exterminate! Seek, locate, destroy! (Firing at The Doctor and Bill)
The Doctor takes a breath.
Bill: What's that thing?
The Doctor: A Dalek.
Bill: A what?
The Doctor: A Dalek.
Bill: What's a Dalek?!
The Doctor: Nevermind, it's a Dalek...
Bill: Well that's not explaining, that's just saying a word - what's a Dalek?!
The Doctor: It's an alien war machine. The deadliest alien war machine ever devised.
Daleks: (In the distance...) Exterminate! Exterminate!
Bill: Fat, though.
The Doctor: I'm sorry?
Bill: Well they'll never get through that door - it's too wide!
The Doctor chuckles softly...
The Doctor: (Whispering) It's a tank, a tank driven by a super evolved mutant. Programmed to wipe out all other lifeforms, so please - keep your voice down.
Daleks: (In the distance...) Exterminate!
Bill: It's got a s**er on it.
The Doctor: It's also got a gun.
Bill: (Laughing) It's got a gun and a s**er - why? D'they run out of guns?
The Doctor: Bill, please.
Bill: (Joking) Is there a Dalek at the back with no gun and two s**ers and it's really hacked off?
The Doctor: I don't know - I've never asked because I've always been too busy running away. Now, please - shh...
Daleks: (In the distance...) Exterminate!
Bill: One more question...
The Doctor: (Sarcastically) Oh, you do surprise me!
Bill: Why do they keep saying "exterminate?"
The Doctor: Because they want to k** us.
Bill: Wouldn't it be quicker to just say "k**?"
The Doctor: Do you really want them to save time?
Bill: (Realising the ridiculousness of her question) Good point.
The Doctor: (Gasps) We need to get back!
Bill: (Confused) Back where?
The Doctor: To the future. 2017 needs us.
The Doctor and Bill run along the corridor frantically. A dalek has begun to chase them.
Dalek: Exterminate! Humanoid detected!
The Dalek is preparing to exterminate The Doctor and Bill. The pair hold hands and stare at the dalek terrified.
