Romana
- Doctor Who: We have the power to do anything we like, absolute power over every particle in the universe, everything that has ever existed or ever will exist as from this moment. Are you listening to me, Romana?
- Romana: Yes, of course, I'm listening.
- Doctor Who: 'Cause if you're not listening I can make you listen, because I can do anything. As from this moment there's no such thing as free will in the entire universe. There's only my will because I possess the Key to Time.
- Doctor Who: Well if I knew where I was going, there'd be a chance the Black Guardian would, too - hm? - hence, this new device.
- Romana: What is it?
- Doctor Who: Ah, well, it's called a randomizer, and it's fitted to the guidance systems and operates under a very complex scientific principle called pot luck. Now, no one knows where we're going, not even the Black Guardian.
