- Jamie: Why did you run away from them in the first place?
- The Doctor: What? Well, I was bored.
- Zoe: What do you mean, you were bored?
- The Doctor: Well, the Time Lords are an immensely civilised race. We can control our own environment, we can live forever, barring accidents, and we have the secret of space time travel.
- Jamie: Well what's so wrong in all that?
- The Doctor: Well we hardly ever use our great powers. We consent simply to observe and to gather knowledge.
- Zoe: And that wasn't enough for you?
- The Doctor: No, of course not. With a whole galaxy to explore? Millions of planets, eons of time, countless civilisations to meet?
- Jamie: Well, why do they object to you doing all that?
- The Doctor: Well, It is a fact, Jamie, that I do tend to get involved with things.
