- The Doctor: Well, when I was on the river I heard a strange babble of inhuman voices, didn't you, Romana?
- Romana: Yes!
- Professor Chronotis: Oh, undergraduates talking to each other, I expect. I've tried to have it banned.
- Romana: I just mouthed the words like everyone else.
- The Doctor: What words?
- Romana: At the Time Academy Induction ceremony, you know: "I swear to protect the ancient law of Gallifrey with all my might and main, I will to the end of my days with justice and with honour temper my actions and my thoughts."
- The Doctor: Pompous lot, all words and no action.

- Romana: [from off-camera] I wonder if the stories of Salyavin were exaggerated?
- The Doctor: [off camera, under the Tardis console] More than likely, Time Lords overreact to everything. Look at the way they treat me. I expect that some time in the future, in about 200 years' time, someone will meet me... .
- The Doctor: [standing up from under the console, revealing his face] ... and say, "Is that really the Doctor? He seemed such a nice old man!"
- Chris Parsons: Where is this place?
- The Doctor: How should I know?
- Chris Parsons: Big, isn't it?
- The Doctor: I wonder where everybody's got to?
- Chris Parsons: I don't know.
- The Doctor: Neither do I.
- Chris Parsons: And I don't believe that we travelled hundreds of light years.
- The Doctor: Why not?
- Chris Parsons: You cannot travel faster than light. Einstein.
- The Doctor: What? Do you understand Einstein?
- Chris Parsons: Yes.
- The Doctor: What? And quantum theory?
- Chris Parsons: Yes.
- The Doctor: What? And Planck?
- Chris Parsons: Yes.
- The Doctor: What? And Newton?
- Chris Parsons: Yes.
- The Doctor: What? And Schoenberg?
- Chris Parsons: Of course.
- The Doctor: You've got a lot to unlearn
