VICKI: It’s a pity they got it all wrong.
DOCTOR: Hmm? Got it all wrong? What do you mean child? Hmm?
VICKI: Well, they didn’t mention you.
DOCTOR: Ah, of course not. Why should they? Hmm?
VICKI: Well, it was you who gave Nero the idea, wasn’t it?
DOCTOR: I?…Gave him.
VICKI: Honestly, Doctor! And after that long talk you gave me about not meddling with history, you ought to be ashamed of yourself.
DOCTOR: It’s got nothing to do with me!
VICKI: You burnt his drawings!
DOCTOR: Oh, yes, an accident!
VICKI: Well, maybe it was but if you hadn’t….
DOCTOR: Well, he could have…he could have, he would have been told someone else, you can’t possibly accuse me of that! Hmm?
VICKI: All right, you have it your way, I’ll have it mine.
DOCTOR: Now look here, young lady, lets settle this. Insinuating that all this is…my fault. Hmm? My fault!
