- Riley Vashtee: [reading from display] Find the next number in the sequence: 313, 331, 367...? What?
- Martha Jones: You said the crew knew all the answers!
- Riley Vashtee: The crew's changed since we set the questions.
- Martha Jones: You're joking!
- The Doctor: 379!
- Martha Jones: What?
- The Doctor: It's a sequence of happy primes - 379!
- Martha Jones: Happy what?
- The Doctor: Just enter it!
- Riley Vashtee: Are you sure? We only get one chance.
- The Doctor: Any number that reduces to one when you take the sum of the square of its digits and continue iterating it until it yields 1 is a happy number, any number that doesn't, isn't. A happy prime is both happy and prime. Now type it in!

- The Doctor: I dunno, talk about dumbing down. Don't they teach recreational mathematics anymore?
- Riley Vashtee: The wonderful world of space travel. The prettier it looks, the more likely it is to kill you.
- Riley Vashtee: These doors' trip code is the answer to a random question set by the crew. Nine tours back, we got drunk, thought them up. Reckoning was, if we're hijacked, we're the only ones who know all the answers.
- Martha Jones: So you type in the right answer...
- Riley Vashtee: This sends a remote pulse to the clamp. But we only get one chance per door. Get it wrong, the whole system freezes.
- Martha Jones: Better not get it wrong, then.
- Riley Vashtee: Okay.
- [reading]
- Riley Vashtee: 'Date of the SS Pentalian's first flight?' That's all right. Go!
- Martha Jones: [door opens] Yes!
- Riley Vashtee: Twenty eight more to go!
- [Later]
- Riley Vashtee: [reading] 'Find the next number in the sequence: 313, 331, 367...?' What?
- Martha Jones: You said the crew knew all the answers.
- Riley Vashtee: The crew's changed since we set the questions.
- Orin Scannell: What's your favorite color?
- Riley Vashtee: You what?
- Orin Scannell: It's the question.
- Riley Vashtee: Purple.
- [Orin begins to type in the answer]
- Riley Vashtee: Or did I say orange?
- Orin Scannell: Come on!
