Ace
- The Doctor: Ace, where do you think you're going?
- Ace: Perivale.
- The Doctor: Ah, yes, but by which route - the direct route with Glitz or the scenic route? Well, do you fancy a quick trip 'round the twelve galaxies and then back to Perivale in time for tea?
- Ace: Ace!
- The Doctor: But there are three rules. One: I'm in charge.
- Ace: Whatever you say, Professor.
- The Doctor: Two: I'm not the Professor. I'm the Doctor.
- Ace: Whatever you want.
- The Doctor: And the third... Well, I'll think up the third by the time we get back to Perivale.
