The Roof of the World
(Inside the ship, the scanner shows a large footprint in the snow outside. Barbara and Susan are knelt over it.)
SUSAN: Must've been made by a giant.
(Ian exits the ship – a police box – dressed in a large ulster. Behind him comes the Princess, dressed in a black shawl and gloves, and the Doctor in his usual attire. Ian joins Barbara and Susan, kneeling down next to the footprint.)
SUSAN: (To Ian) What do you make of this?
IAN: Well, it could be a perfectly ordinary footprint, Susan. And the sun's melted the edges and made it look a bit bigger.
(Ian notices the Doctor and Princess stood by the ship, looking out of breath. Ian stands up.)
IAN: You all right, Princess?
(Barbara and Susan also stand up.)
PRINCESS: (Breathless) Yes, fine… Just…Just a little…breathless.
DOCTOR: Oh, that's quite understandable. After all, we're several thousand feet above sea level.
SUSAN: Do you know where we are then, Grandfather?
DOCTOR: Well, I directed the ship towards Earth, and it looks as though I've been successful.
SUSAN: But what about that?
(Susan points towards the footprint. The Doctor and the Princess look from where they stand.)
DOCTOR: What is it?
PRINCESS: A footprint, I think?
DOCTOR: Oh, I can't see anything without my glasses. Anyway, I don't like this place. You'll have to excuse me. I've got a lot of work to do first.
(The Doctor goes back into the ship, while Ian leads Barbara aside. The Princess joins Susan by the large footprint.)
PRINCESS: (To Susan) It is quite big, isn't it?
SUSAN: Mr. Chesterton thinks it's a normal footprint which has gotten bigger as the sun melted the snow.
(The Princess shivers.)
PRINCESS: I'd have an easier time believing that if it wasn't so cold.
SUSAN: (Panicked) Do you think he could be wrong?
PRINCESS: No, no, of course not. I'm just having a little moan, that's all. I'll be fine once we're warmed up.
(The Doctor exits the ship grumbling angrily to himself. In his hand he holds a small box with wires coming out of a circuit board.)
DOCTOR: (Angrily) Oh, dear, dear, dear, dear. We're always in trouble, Isn't this extraordinary? It follows us everywhere.
(They all gather around the Doctor.)
IAN: (To Doctor) What's the matter?
DOCTOR: All the lights in the ship have gone out! The whole circuit has burned itself to a cinder!
PRINCESS: I'm sorry, that might have been my doing with the little jolt I give the ship earlier.
DOCTOR: Yes, it very probably was, and now look at what you've done!
BARBARA: All right, what's done is done. Besides the Princess had to do…what she did to get us free, didn't she?
DOCTOR: Well, yes of course…! (Grumbles) It would have been better however, had she not broken my ship to do it.
BARBARA: How has she broken your ship?
DOCTOR: Well what she did affected the water. We haven't got any.
IAN: Well, the water's no bother, Doctor. I mean, we've got snow, plenty of it. But how about the heating?
DOCTOR: Oh, the heating as well. Everything's gone to pot.
PRINCESS: Everything? You mean we can't even leave.
DOCTOR: Yes, everything!
BARBARA: But that's serious. We could freeze to death without heating up here.
DOCTOR: Serious– Are you telling– There's no need for you to tell me that, really!
IAN: I think I'd better try and find some fuel.
DOCTOR: Fuel? Now where on earth do you expect to find fuel here, hmm?
(The Doctor waves at the frozen mountain they are on top off. Nothing but more snow and slippery steep slopes all around them.)
IAN: Well, I must try, mustn't I?
DOCTOR: Oh well, I wish you luck!
BARBARA: I'll come with you, Ian.
IAN: Thank you.
SUSAN: Yes, me too.
IAN: No, Susan, you stay here.
DOCTOR: You stay with me, child, and you too, Princess. You both might be able to help me.
SUSAN: Okay.
IAN: Come on, Barbara, we haven't much time.
(Ian and Barbara walk away towards the safest slope down.)
DOCTOR: Now, Susan, go into the ship and fetch me the tubular, will you? You know what it is.
(Susan goes into the ship.)
DOCTOR: Even if I do find the fault, I don't suppose I shall be able to repair it before it gets dark, and then we shall all freeze to death!
PRINCESS: Why don't we go inside. It'll be easier to work in there than out here in this snow.
(The Princess prods the Doctor back inside the ship before closing the doors behind them.)
DOCTOR: Oh, stop pushing me around as if I'm one of your servants!
(The Doctor exits the ship some time later. Behind him, the Princess and Susan follow him out. In the Doctor's hand he still holds the same circuit as before.)
DOCTOR: (Continuing) No, no, no. I'm afraid it's going to need a new one. It's going to take me days. Oh well, I don't know, really, I always seem to… (Trails off)
(Ian and Barbara return.)
DOCTOR: Well, Chesterton?
IAN: Just as you predicted, Doctor, nothing but snow and ice.
BARBARA: Have you found the fault?
DOCTOR: Yes, yes, yes, but it's going to take such a long time to fix. Time we don't have. Now the only chance is to try and get down to a lower altitude and find shelter before it gets too cold.
BARBARA: Doctor, there are strange things on the mountain. I saw one of them.
DOCTOR: (To Ian) What's she talking about now?
IAN: Well, I only saw a print.
DOCTOR: Print? What sort of print? Paws, hooves, what?
IAN: To tell you the truth, I thought it was made by a fur boot.
BARBARA: No, Ian, I'm sure it wasn't human.
DOCTOR: And if it were, that means there's shelter nearby.
PRINCESS: Unless Barbara is right. And even if you and Ian are, who's to say these people are friendly. What if they're like the cavemen?
DOCTOR: That might just be a risk we have–
SUSAN: (Screams) Look!
(They turn to see a man, dressed in fur clothing, behind a rock.)
BARBARA: (Pointing) Look, there it is.
(The man runs out from behind the rock and down the slope.)
IAN: Quick, after it. It's our only chance of shelter.
(Ian and Barbara quickly take off after the man. Susan and the Princess go to follow but stop when they see the Doctor is lingering behind to lock up the ship.)
SUSAN: Come on, Grandfather!
DOCTOR: All right! Yes, yes, yes, yes.
(The Doctor, having locked the ship, puts his key away and the three chase off after Ian, Barbara and the man.)
(A little way down the mountain, Ian comes to a stop. Barbara stops alongside him as they look around.)
IAN: Which way did it go?
(As Ian and Barbara look around, Susan arrives with the Doctor and Princess – both of which are staggering and out of breath… Then suddenly, a dozen men come out of hiding. Susan gasps in fright, hugging herself against the Doctor and Princess. The time travellers are surrounded by Mongols, all armed with swords.)
SUSAN: (Quietly) Grandfather…
IAN: Keep still. (To Mongols) We are travellers, lost on the mountains. Will you give us shelter?
(One of the Mongols steps forward. The leader of the group. His name is Tegana. He looks over the five travellers, then turns to his men.)
TEGANA: Hear me, Mongols. In these parts live evil spirits, who take our likeness to deceive us and then lead us to our deaths. Let us therefore destroy these evil spirits before they destroy us.
IAN: (To Tegana) We're not evil spirits. We are people like yourselves.
TEGANA: (To Mongols) Destroy them.
(They are about to attack. The time travellers brace themselves…)
MARCO POLO: Stop!
(The Mongols hold their attack. A man has appeared behind the travellers. He is different to the Mongols and their leader. This man is Marco Polo. He steps around the travellers, moving towards Tegana.)
MARCO POLO: (To Mongols) Put up your swords.
(The Mongols rise their swords. Still drawn, but no longer pointed at the travellers, who now relax a little.)
TEGANA: (Shocked) Would you have us killed? These are evil spirits!
MARCO POLO: I command you in the name of Kublai Khan!
(Marco Polo and Tegana stare off for a moment... Then, Tegana puts his own sword away. The Mongols follow his lead, sheathing their own weapons. With the threat gone, Marco Polo approaches the travellers. He notices the weak Doctor and Princess.)
MARCO POLO: (To Ian) The old couple, they have the mountain sickness?
PRINCESS: (Coughing) C–Couple?
IAN: (To Marco Polo) Yes, they have.
MARCO POLO: My caravan is further down the pass. Come.
(Marco Polo walks down the slope. Some of the Mongols follow. Others wait with Tegana for the travellers to move.)
IAN: Come on, Doctor.
(Ian takes a breathless Doctor and helps him down the slope. Barbara and Susan do the same for the Princes, who is also struggling to breath. As they walk, Susan looks ahead to the man who saved their lives.)
SUSAN: Who is he, Barbara?
BARBARA: I was asking myself the same question.
(Unbeknownst to the travellers, behind them Tegana glares at them with spiteful eyes.)
(Marco Polo leads the group into a lavish tent. Inside is a girl already making soup in the centre of the room.)
MARCO POLO: (To the girl) We have guests, Ping-Cho. They are cold and hungry.
PING-CHO: Yes, Messer Marco.
(Ian takes the Doctor over to a seat offered by Marco Polo)
IAN: Sit down, Doctor. Barbara, bring her over here as well.
(Ian sits the Doctor down on the chair. Marco swiftly brings another over for Barbara to sit the Princess down on. Ping-Cho then brings over two bowls of soup, one for each of the old travellers.)
DOCTOR: (To Ping-Cho) Thank you, my dear.
(The Doctor and the Princess have a spoonful of soup.)
PRINCESS: Oh, that's nice. Thank you.
(While the old pair continue to eat, Ian removes his ulster. Barbara and Susan are also given seats and sit down, accepting more bowls of soup offered by Ping-Cho. Both Susan and Barbara stare at Marco Polo for a moment.)
SUSAN: (Whispers to Barbara) He's not like her, or any of the others.
BARBARA: No, he's a European, Susan. And he mentioned Kublai Khan.
SUSAN: Kublai Khan?
BARBARA: He was a great Mongol leader, who conquered all of Asia. He had a European in his service. He was a Venetian and his name–
MARCO POLO: I'm afraid the liquid is not too warm, but the cold here is so intense, it even robs a flame of its heat.
(Ian sits down on a chair beside the Doctor and Princess, as Ping-Cho offers him soup.)
PRINCESS: (To Marco Polo) Even so, we greatly appreciate it.
DOCTOR: Oh, yes, it's excellent nourishment, sir.
IAN: (To Marco Polo) The cold can't affect the heat of the flame, sir. The liquid boils at a lower temperature, because there's so little air up here.
MARCO POLO: You mean the air is responsible?
IAN: Well, the lack of it. Just as the lack of it is responsible for the mountain sickness.
BARBARA: Is your name Marco Polo?
MARCO POLO: It is, my lady, and may I ask who you are?
DOCTOR: Oh, we're–we're travellers, yes. That's my grandchild, Susan, and that's Miss Wright, and that's Charlton.
PRINCESS: Oh, Doctor!
(The Princess slaps the back of her hand against the Doctor's knee, but he takes no notice as he continues with his soup.)
IAN: (To Marco Polo) Chesterton. Ian Chesterton.
MARCO POLO: But who is this?
(Marco looks to the Princess.)
DOCTOR: (Quickly) Well, eh, that's-that's rather complicated, sir.
MARCO POLO: What's so complicated about a name?
DOCTOR: It's not so much a name, as it is a title. She's a princess you see.
(The Princess narrows her eyes angrily at the Doctor, but he ignores her.)
MARCO POLO: A princess? Up here? Forgive me but–
BARBARA: We're fleeing war torn lands.
DOCTOR: Yes, that's right. And we had to get her highness away.
MARCO POLO: I'm sorry to hear that, Princess…?
DOCTOR: Just Princess will do.
(Further glaring from the Princess.)
MARCO POLO: Very well. My companions are the Lady Ping-Cho, and the Warlord Tegana. We travel to Shang Tu.
BARBARA: Shang Tu? That's in China, isn't it?
MARCO POLO: China? I do not know this place. Shang Tu is in Cathay.
BARBARA: Oh, silly of me. Yes, of course, Cathay.
MARCO POLO: Well, you must all be very tired. Ping-Cho, you will share your quarters with…? (He looks to Susan)
SUSAN: Susan.
MARCO POLO: (Continuing) Susan. I will sleep here with the others, and the Princess and Lady…?
BARBARA: Miss Wright.
MARCO POLO: (Continuing) Miss Wright. The two of you shall have mine.
PRINCESS: That's very kind of you, sir.
DOCTOR: Yes, thank you. You saved our lives.
MARCO POLO: I'm rather curious to know why you were wandering around the mountainside at night, but questions can wait until morning.
DOCTOR: Oh, there were two, young man, that I would like to ask.
MARCO POLO: Well, ask them.
DOCTOR: What year is this and where are we, hmm?
MARCO POLO: You do not know?
DOCTOR: No, that is why I'm asking you.
PRINCESS: (Quietly warning) Doctor…
MARCO POLO: How long have you been travelling? It is twelve hundred and eighty-nine and this is the Plain of Pamir, known to those who travel to Cathay as The Roof of the World.
IAN: (Stunned) The Roof of the World?
DOCTOR: Twelve hundred and eighty-nine. Ah!
MACRO POLO: Well, with that I think we should all retire for the night. Ping-Cho, show Susan to your quarters.
(Ping-Cho leads Susan to another section of the tent.)
MARCO POLO: Princess, my room is through there, I'll have another bed made up for Miss Wright.
BARBARA: Thank you.
(The Princess gets up along with Barbara and the two head into Marco Polo's quarters for some sleep.)
(The next day, the Doctor and Princess are once again sat in the tent. Across the room, Ping-Cho is preparing another soup.)
DOCTOR: (To Princess) Susan told you she slept well, did she?
PRINCESS: Yes. I think it's good for her, being around someone her own age again. Apparently, they stayed up for quite a while talking.
DOCTOR: Yes, I must say I can see the appeal. It's a good thing we have each other, my dear.
PRINCESS: Yes, otherwise who would we argue with all the time?
(They both laugh.)
DOCTOR: (Chuckling) Yes, we do like to bicker from time to time.
(The Princess looks around the empty tent, save for Ping-Cho.)
PRINCESS: Where has everyone else gone?
DOCTOR: Up the mountain to see the ship. Messer Marco seemed very fascinated by it. I would have gone with them, but I thought it best to stay here and keep you company my dear.
PRINCESS: (Grinning) They wouldn't let you go would they.
DOCTOR: Nonsense, I make my own decisions! You see, this is why we keep arguing all the time. Because you keep making ridiculous comments like that I mean really, my dear, really. I don't know where you get such ideas from.
(As the Doctor rants, the Princess chuckles to herself. Afterwards, the Princess gets up and approaches the cooking pot Ping-Cho is cooking with. The Princess takes a sniff, brushing back her red hair.)
PRINCESS: It smells great, Ping-Cho. What is it, if you don't mind me asking?
PING-CHO: Not at all. It's Bean-sprout soup, your highness.
PRINCESS: Please, just call me, Princess, I'm not one for formality.
(The Doctor gets up and joins them at the cooking pot.)
DOCTOR: (To Ping-Cho) May I have a taste?
PING-CHO: Of course.
(Ping-Cho gives the Doctor the spoon and he samples the soup.)
DOCTOR: Oh, it's delicious, delicious.
PING-CHO: My lord is kind.
DOCTOR: You know, it's rather surprising to find the daughter of a high government official working as a servant in Marco Polo's caravan.
PING-CHO: I wish to serve, my lord, although, among Messer Marco's retinue, there is a man who calls himself a cook.
PRINCESS: I bet he's not half as good as you.
(Ping-Cho giggles at the compliment.)
PRINCESS: May I have a taste too?
(Ping-Cho passes the spoon to the Princess, who takes a taste.)
PRINCESS: Hmm! The Doctor's right, this is delicious, Ping-Cho.
PING-CHO: Thank you, your high– I mean, Princess.
(The Princess smiles at Ping-Cho.)
DOCTOR: Ping-Cho, this cook your referred to, his name wouldn't be Tegana, would it?
PING-CHO: Oh no, my lord. The Warlord Tegana is a special emissary from the camp of the great Mongol Lord Khan Noghai, who has been at war with Kublai Khan.
DOCTOR: (Dryly) Yes, Mongol fighting Mongol.
(He looks to the Princess with an eye roll, to which she raises her brow at him in turn.)
PING-CHO: The war is over, my lord. Noghai has sued for peace and Tegana travels to Kublai's court to discuss the armistice plans.
DOCTOR: Well, for an emissary of peace, he has some rather blood-thirsty habits, doesn't he?
PRINCESS: Yes, certainly didn't seem the friendliest of people, I must say.
(The Doctor and Princess return to their seats. Marco Polo, Ian, Barbara and Susan return and enter the tent.)
MARCO POLO: I find your caravan most unusual, Doctor.
DOCTOR: Yes, Messer Marco, it is different.
MARCO POLO: And in need of repair?
DOCTOR: That is true.
SUSAN: (To Doctor) Messer Marco has ordered a sledge to be made. He's going to bring the Tardis down here.
DOCTOR: Oh indeed? (To Marco Polo) That's charming of you. Very charming of you. It won't take me very long to repair. A day or two. But I assure you that I shall not hold up your journey any longer than is necessary.
MARCO POLO: I'm afraid we can't stay here. One crosses the Plain of Pamir as quickly as possible. However, we will be spending a few days at Lop.
BARBARA: Lop? Where's that?
MARCO POLO: It's a town on the edge of the Gobi Desert, beyond Kashgar and Yarkand.
DOCTOR: I see, and you will be taking us along with you, including the Tardis?
MARCO POLO: Doctor, I once transported an entire army and its equipment from Cathay to India, all without loss.
DOCTOR: Oh good, good. Then I can work as we proceed.
MARCO POLO: Emm…no.
DOCTOR: (Angrily) Why not, hmm?
(Marco polo sighs.)
MARCO POLO: The Mongol bearers still half believe that you are evil spirits. They also believe that outside your caravan you are harmless. However, should any of you attempt to enter, there would be trouble.
PRINCESS: You say they, "half believe"? Do you think that will stop once we reach Lop?
MARCO POLO: Yes. Up here on these mountains, superstitions run wild. But once we're off the mountain and in Lop, they will see sense, I believe.
DOCTOR: So, once we get to Lop, I'd be able to work on the Tardis?
MARCO POLO: Yes.
PRINCESS: (To Doctor) That seems reasonable. He did save our lives after all.
DOCTOR: Yes... Very well, we shall respect your wishes, Messer Marco. No one will enter the Tardis until we reach Lop.
MARCO POLO: (Smiling) Good.
(A few days later, in the courtyard of the way-station at Lop, Mongol bearers are unload the various caravans belonging to Marco Polo. Ian and Barbara are watching, both wearing rice hats. In the corner of the courtyard, Tegana watches them. After a moment, Tegana then heads inside the lodgings, where Marco Polo is speaking with the proprietor.)
MARCO POLO: My caravan is large, Yeng, so I shall need plenty of food and water before venturing out into the Gobi Desert.
(Yeng nods and then leaves. In corner of the room, Tegana takes a bowl of food and stands quietly eating. Tegana now watches the Doctor and the Princess, who are sat in the room with fans. The Princess is no longer wearing her shawl and is once again seen in her red and black dress. Laughter comes from the stairs. Then Susan and Ping-Cho come down.)
MARCO POLO: Is the accommodation to your liking, Ping-Cho?
(Ping-Cho and Susan approach Macro Polo who is stood near where the Doctor and Princess are sat.)
PING-CHO: Thank you, Messer Marco. It is most comfortable.
SUSAN: Oh, I think it's fab.
PING-CHO: Fab? What is that, Susan?
SUSAN: Well, it's…it means wonderful. It's a verb we often use.
DOCTOR: Oh, Messer Marco, these way-stations, do you have many of these in Cathay?
MARCO POLO: Yes, the Khan has them dotted at regular intervals throughout his domain. And those who work in his service, and wear the Khan's gold seal, have the right to demand anything they may require. Provisions, horses, shelter.
(Marco Polo holds up the long strip of gold held around his neck by a chain)
PRINCESS: That sounds Fab.
(Susan and Ping-Cho laugh.)
DOCTOR: Oh, do act your age, my dear!
PRINCESS: You're one to talk.
(Ian and Barbara enter from the courtyard.)
IAN: Doctor?
DOCTOR: Yes?
IAN: They've set the Tardis up in the courtyard.
DOCTOR: Oh, excellent, excellent. If you'll pardon me, I have a lot of work to do.
(The Doctor gets up and goes out the front door... But is then met by Mongol guards with their swords pointed at him. After a moment, the Doctor then storms back inside and towards Marco Polo.)
DOCTOR: (To Marco Polo) What does this mean?!
MARCO POLO: Please, sit down, Doctor.
DOCTOR: I don't wish to sit down. I want you to call your guards off!
PRINCESS: What's going on?
MARCO POLO: (To Doctor) Please be seated.
DOCTOR: No!
MARCO POLO: I beg you to hear me out.
DOCTOR: But I have work to do!
BARBARA: (To Doctor) I think, perhaps, we should listen to him.
PRINCESS: (To Doctor) Yes, let's get to the bottom of this before you overheat.
(The Doctor hesitates a moment. Then reluctantly sits down in his original seat.)
DOCTOR: Oh, very well!
MARCO POLO: My home is Venice. I left there with my father and my uncle to come to Cathay in twelve seventy-one. The journey to Peking took us three and a half years. When I arrived at the Khan's court, I was twenty-one. I was an alert young man, good at languages, and willing to learn. The Khan liked me.
DOCTOR: (Sarcastically) Oh, really?
(The Princess slaps the Doctor on the knee and gives him a warning stare.)
MARCO POLO: (Continuing) On my twenty-fifth birthday, I was given an appointment in the Khan's service.
BARBARA: Twelve seventy-seven.
MARCO POLO: It was, as you say, twelve seventy-seven. Since then, I have travelled to every corner of his domain and beyond it. Two years ago, my father, my uncle and I asked the Khan for permission to go home. He refused. I think we had all served him too well.
DOCTOR: Well, I really don't see what this has to do with my repairing the Tardis.
MARCO POLO: Doctor, I have not seen my home for eighteen years. I want to go back.
DOCTOR: Well, ask the Khan again!
MARCO POLO: I intend to! But this time, I shall offer him a gift so magnificent that he will not be able to refuse me.
(For a moment, the time travellers are all confused. Then Ian realises it.)
IAN: You mean to give the Doctor's caravan to him?
MARCO POLO: Yes.
(They are all shocked.)
PRINCESS: Marco, you can't–
(The Doctor gets up.)
DOCTOR: (To Marco Polo) You're mad!
MARCO POLO: You can make another.
DOCTOR: What? In Peking, or Shang Tu?!
MARCO POLO: You do me an injustice, Doctor. I will not leave you stranded in Cathay, just as I did not let you die on the mountain. No, you will come with me to Venice and make another one there.
DOCTOR: Oh, you think so, really?!
PRINCESS: Marco, it's not as simple as just making another one.
MARCO POLO: Surely, for a man who possesses a flying caravan, all things are possible?!
(Ian steps forward.)
IAN: (To Marco Polo) No. We need special metals, materials, things that don't exist in Venice. I'm afraid you don't understand all the problems involved.
DOCTOR: (To Ian) And neither do you, young man!
MARCO POLO: We'll travel home by ship. We trade with every port in the world. It may take you longer, but you'll get there eventually.
DOCTOR: Eventually! He doesn't know what he's talking about. The man's a lunatic.
MARCO POLO: No, Doctor, desperate. There are many men who are jealous of the Polo influence at court, and the Khan suffers from an affliction for which there is no cure.
BARBARA: What's that?
MARCO POLO: Old age. If he dies, I may never see Venice again.
DOCTOR: Well, that is your problem, not mine!
MARCO POLO: I have just made it yours, Doctor.
BARBARA: But you do see Venice again, Marco, I know you do.
(Marco Polo stares curiously at Barbara.)
IAN: (To Marco Polo) What makes you so sure that the Doctor's caravan is a suitable present? The Doctor is the only one who can fly it.
MARCO POLO: I told you about the Buddhist monks. They will discover its secret.
(The Doctor begins to laugh madly.)
MARCO POLO: A caravan that flies, do you imagine what this will mean to the Khan? It will make him the most powerful ruler the world has ever known. Stronger than Hannibal. Mightier than Alexander the Great.
(From the corner, Tegana is taking interest in the conversation.)
IAN: Marco, you don't understand–
PRINCESS: Please, just–
MARCO POLO: I refuse to listen to any more! My mind is made up. Your caravan goes with me to Kublai Khan.
(Marco exits. The Doctor is now laughing uncontrollably.)
BARBARA: Doctor, come on. Come and sit down.
(Barbara takes the Doctor back over to his seat. The Doctor and Princess are now seated with Ian, Barbara and Susan stood around them.)
DOCTOR: (Laughing) Oh, what a mess!
(The Doctor continues to laugh madly.)
SUSAN: Grandfather? Grandfather?
DOCTOR: (Still laughing) Yes. Go by sea, he says.
SUSAN: (Panicked) Why are you laughing? He means it!
BARBARA: Doctor, he's serious.
DOCTOR: (Still laughing) I know he is! Yes.
SUSAN: What are you going to do?
DOCTOR: (In total hysterics) I haven't the faintest idea!
(Then, one by one, the other four travellers begin to laugh along with him.)
