In the great days of Rassilon 5 great principles were laid down. Can you remember what they were, my children?
It's just a Gallifreyan nursery book
I know, I know!
I had it when I was a time-tot.
S17Shada
Professor, how many books did you bring back, for heaven's sake?
Just the odd two or seven.
Really, Doctor? A great criminal your hero?
Well, a criminal, yes, but he had such style, such flair, such-
Panache!
(to the professor) I'll be back in two minutes. (to Romana) If I'm not back in two hours you and the professor lock yourselves in the TARDIS, send out an all-frequency alert and wait!
I haven't got any books. That's to say, I've got plenty of books. What book would you like?
I am Skagra. I want the book.
Well I'm the Doctor and you can't have it.
Well Mr. Skagra, or whatever it is you call yourself, you killed a Time Lord, a very old friend of mine. It's time you and I had a little chat!
Think of me as an anomaly within an impossibility, and get on with your tea.
'Take over the Universe'. How childish. Who could possibly want to take over the Universe?
Exactly! That's what I keep on trying to tell people. It's a troublesome place, difficult to administer, and as a piece of real estate it's worthless because by definition there'd be no one to sell it to.
This scene was not filmed, but exists in the script.
And twenty-thirdly, out there in the space time vortex, time and distance have no meaning, but here in this little, little room-
Oh, get on with it, Doctor!
SSSkagra's Ship
Do you know the Doctor well? He is a wonderful, wonderful man! He has done the most extraordinary things to my circuitry!
Release me!
SSSkagra's Ship
Truly wonderful! If you like I will tell you all about him!
S17 E1Destiny of the Daleks
[to K9] Say "aah."
KK9
[in a very raspy voice] Aaaaaaahhhhhh...
Aaaah! Aaah, laryingitis! How can a robot catch laryngitis? What do you need it for? Romana!
[Romana II enters, in the form of Princess Astra]
Ah, Romana!, Romana, the dog's got laryngitis. [He turns to look at her] Sorry, I thought you were Romana. Have you seen her? [He does a doubletake, puts the machinery down and steps closer, speaking softly] What are you doing here?
Regenerating. Do you like it?
Regenerating? [He circles Romana II, examining her] What are you talking about, regenerating? Only Time Lords regenerate! Look, it's awfully nice to see you, Princess Astra...
Romana.
Romana! Ahhhhh...
KK9
Aaaaaaahhhhhh...
Shut up, K9. What are you doing in that body?
Regenerating. Do you like it?
But you can't wear that body!
I thought it looked very nice on the princess.
But you can't go around wearing copies of bodies!
Why not? We're not going back to Atrios, are we?
No.
Well then.
Well, go try another one on. Go on.
All right.
[Romana II enters wearing clothing exactly like to the Doctor's, including a hat which shades most of her face and covers her eyes]
What about this, Doctor?
Exactly! Good heavens, that's exactly right! Ha! I never realized you had such a sense of style!
I thought you said external appearances weren't important.
[smiling] Ah, but it's nice to get them right, though, isn't it?
[attempting to mimic the Doctor's voice] Ah, but it's what's inside that counts.
Exactly! [pulls off Romana II's hat to reveal - Astra] Oh.
Don't you like it? I think it'll do very nicely. If the arms are a bit long I can always take them in.
No, no, no! The arms are just fine.
[incredibly enthusiastically] Oh, look! Rocks!
[The Doctor holds his head, as if he has a headache]
What is it?
I don't know. I have the feeling I've been here before.
Déjà vu?
[speaking French] Oui. [jumps down off of the rock he and Romana II are standing on, walks forward, and takes a look around, as if looking for something]
Is there something you recognize?
Nothing tangible. [walks back over towards Romana II] Just have a sensation, a pervading air of- [cuts off mid-sentence and looks at Romana II] can you feel it too?
Should we go back inside?
What?! And never know where I've been for the end of time? [starts to walk away and then turns around] I wouldn't sleep at night. Come on.
