- The Doctor: The TARDIS, when working properly, is capable of many amazing things. Not unlike myself.
- Russell: Who are you?
- The Doctor: I've already told you. I am known as the Doctor. I'm also a Time Lord from the planet Gallifrey in the constellation of Kasterborous.
- Russell: You're bonkers.
- The Doctor: That's debatable.
- Perpugilliam 'Peri' Brown: What is that terrible smell?
- Lytton: Death.
- Griffiths: Trust him to cheer everyone up.
- Perpugilliam 'Peri' Brown: What do you mean, death?
- Lytton: The sour, rank odour of death is unmistakable.
- Russell: Who are you?
- The Doctor: I've already told you. I am known as the Doctor. I'm also a Time Lord from the planet Gallifrey in the constellation of Kasterborous.
- Russell: You're bonkers.
- The Doctor: That's debatable.
- Lytton: You know, Griffiths, when I look at you, I wonder why your ancestors bothered to crawl out of the primordial slime.
- Perpugilliam 'Peri' Brown: Will it believe you?
- The Doctor: If it doesn't, I shall beat it into submission with my charm.
- Perpugilliam 'Peri' Brown: Look, Doctor, since you regenerated, it's as though your memory's been put through the meat grinder. I mean, it's all there, but in a pile of unrelated bits and pieces.
- The Doctor: That's a horrible simile.
- Perpugilliam 'Peri' Brown: It's true, though. In the past couple of days you've called me Tegan, Zoe, Susan. On one occasion you even referred to me as Jamie.
- The Doctor: Merely slips of the tongue.
- Perpugilliam 'Peri' Brown: I rather think they're slips of the mind. And while we're about it, who is this Terrible Zodin?
- The Doctor: I called you Zodin, did I? Oh, they don't make villains like her anymore. A woman of rare guile and devilish cunning.
- Perpugilliam 'Peri' Brown: [sarcastically] Thanks a lot.
- The Doctor: Perhaps you're right. My mind may be playing tricks on me. You know, I haven't thought about Zodin for years.
