CHRIS: The overrides are biometrically linked to me.

DOCTOR: So I’d need a sample of your DNA to trip the lock. Right! You know what you need to do.

CHRIS: Oh, all right, fine. I’ll kiss you.

(Mwah! Chris kisses the Doctor.)

DOCTOR: Oh. No, I just meant a follicle of your hair.

CHRIS: Oh. Really?

DOCTOR: But don’t worry about it.

CHRIS: Oh, I’m so embarrassed.

DOCTOR: There should be enough on my lips, um—oh, actually I probably need a bit extra. Hang on.

(Mmmmwah! The Doctor kisses Chris back.)

MR COLCHESTER: You can never go wrong with the Muppets.

ACE: The Doctor once showed the film to Charles Dickens. He died a very happy man.

TEGAN: I was angry about the suppression coronet, I still am, but I don't know if I was entirely fair.

ADRIC: People aren't always fair to me.

TEGAN: Shut up Adric.

DOCTOR: You know Tegan, sometimes I wonder how well I'd get along without you.

TEGAN: Thank you.

DOCTOR: Probably quite alright, all things considered. Now, a fresh cup of tea would be terribly useful.

TEGAN: Yeah? Well, you know where the kitchen is.

DOCTOR: There goes my plan A

SARAH JANE: Is there a plan B?

DOCTOR: Eh. Plan B would never work, we'll try plan C.

Ian: None of us has betrayed your friendship, Alexander. Because we are all innocent.

Alexander: Is that all you have to say?

Ian: Yes. You cannot support innocence with a million flowery words. Innocence stands out on its own, like a beacon. Maybe you can't see it now, but one day you will. And if you kill us, on that day, you will regret the injustice.

DOCTOR: Oh yes, I’ve got last words! Several billion last words, in fact! It’s high time, Nobody No-one, that you heard exactly what kind of a man I am…

NOBODY NO-ONE: I’m going to kill everything! Everything that crawls, grows, wiggles and swims in all of reality. Bang! The whole lot! Finished! Kaput! Finito-complete-o! Gone! How’s that for a plan?
