DOCTOR: Well, I can assure you, my dear Barbara, Napoleon would never have believed you.

IAN: Yes, Doctor, but supposing we had written Napoleon a letter, telling him, you know, some of the things that were going to happen to him.

SUSAN: It wouldn't have made any difference, Ian. He'd have forgotten it, or lost it, or thought it was written by a maniac.

BARBARA: I suppose if we'd tried to kill him with a gun, the bullet would have missed him.

DOCTOR: Well, it's hardly fair to speculate, is it? No, I'm afraid you belittle things. Our lives are important, at least to us. But as we see, so we learn.

IAN: And what are we going to see and learn next, Doctor?

DOCTOR: Well, unlike the old adage, my boy, our destiny is in the stars, so let's go and search for it.

JULES: He betrayed us, Barbara.

BARBARA: He was a traitor to you. To his side he was a patriot.

IAN: Barbara, we've taken sides just by being here. Jules actually shot him. It could just as easily have been me.

JULES: And what about Robespierre? I suppose you think-

BARBARA: Well just because an extremist like Robespierre-

IAN: Oh, Barbara, Jules is our friend. He saved our lives!

BARBARA: I know all that! The revolution isn’t all bad, and neither are the people who support it. It changed things for the whole world, and good, honest people gave their lives for that change.

IAN: Well, he got what he deserved.

BARBARA: You check your history books, Ian, before you decide what people deserve.
