- Adric: Doctor?
- The Doctor: Look, whenever you see me in this part of the TARDIS, pacing up and down like this, be a good chap and don't interrupt me, will you, unless it's terribly urgent? It's not terribly urgent, is it?
- Adric: Well, no.
- The Doctor: So now you know. In fact, there's no need for you to come barging in here at all. If it is terribly urgent you could always ring the cloister bell.
- Adric: The cloister bell?
- The Doctor: I sometimes think I should be running a tighter ship.
- Adric: A tighter ship?
- The Doctor: Yes. The second law of thermodynamics is taking its toll on the old thing. Entropy increases.
- The Doctor: Are you really SET on going to Gallifrey?
- Adric: Yes.
- The Doctor: Oh...
- Adric: That IS where we're going, isn't it?
- The Doctor: Well, it was one of the questions I was just pondering. There's bound to be an awful lot of fuss about Romana - why she stayed in E-space, official investigations, that sort of thing...
- Adric: The Time Lords won't approve?
- The Doctor: What? She has broken the cardinal rule of Gallifrey: She has become INVOLVED - and in a pretty permanent sort of way. I think that you and I should let a few oceans flow under a few bridges before we head back home.
- The Doctor: [looking into Romana's room] Ha. I suppose I'm gonna miss Romana.
- Adric: And K-9, too.
- The Doctor: [turning swiftly away] Yes. Still, the future lies this way.
