The Doctor and Sarah reach Earth and try to warn the research centre about the Kraal invasion before Styggron unleashes his virus.
THE ANDROID INVASION by Terry Nation Part Four 5:55pm - 6:20pm [SCENE_BREAK] (Recap from last episode: Int. rocket silo. The Doctor and Sarah consider their options, CSO'ed onto a model shot of a rocket. There's wind blowing their hair around.) DOCTOR: We're going into that rocket, Sarah. SARAH: (can't hear over the wind) What?!! DOCTOR: (louder) I said, you and I are going into that rocket! KRAAL VOICE: (os) Time to lift-off: thirty seconds. (Camera cuts to the interior of that rocket. Sarah and the Doctor enter via a simple door. There are several of the oblong android pods on the floor.) DOCTOR: Come on, Sarah. We need protection. (They rush over to one of the pods and begin opening it.) DOCTOR: The G-forces will crush us on blast-off. (There's an android inside the pod, motionless, just like the one Sarah had found earlier by the TARDIS. Sarah gasps.) DOCTOR: It's all right. It's not activated yet. (They yank the 'droid out of the pod by the arm as the countdown hits 10.) KRAAL VOICE: (os) Ten. Nine. [SCENE_BREAK] (Int. rocket control deck. Styggron is sitting beside Crayford, who is wearing his space suit and controlling the ship.) KRAAL VOICE: (os) Eight. Seven. Six. Five. [SCENE_BREAK] (Int. cargo deck. The Doctor bustles Sarah into the pod.) DOCTOR: In you go, quick! Quick! KRAAL VOICE: (os) Four. Three. (The Doctor looks for a place for himself.) SARAH: Hurry! KRAAL VOICE: (os) Two. One. Zero! (It's too late. The rocket blasts off, and the G-forces immediately press the Doctor down to the ground.) (Cut to stock footage of a Saturn V lift-off. Then cut to a close-up of Sarah's face. She's gritting her teeth, and is obviously having trouble breathing.) SARAH: It's crushing...me...Doctor... [SCENE_BREAK] (Stock footage of a rocket rising into the sky. The camera cuts away about half a second after keen-eyed viewers can spot the beginnings of a stage separation.) [SCENE_BREAK] (Int. rocket, pod bay. The camera is close on Sarah's face. She is unconscious. A hand waves in front of her face, but she does not react until the hand tickles her nose. The camera pulls back as she wakes up, and we see that it's the Doctor.) DOCTOR: We're on the way. (chuckles for no reason) SARAH: (sitting up) ...must've...blacked out. DOCTOR: Yes, you did. The G-force cut the blood supply to what you humans laughingly call your higher centres. (In the background, a pod begins to open. Camera cuts to the side of the pod and we see a Doctor duplicate peer out. It looks around, then closes the lid of the pod again.) SARAH: (os) Ha ha. I hate sarcasm, especially when I'm dying. (The camera cuts back to the Doctor and Sarah.) SARAH: I feel as though I've been through a (unintelligible) DOCTOR: It's a gentle massage compared to what's ahead. SARAH: (annoyed) Oh, no, don't tell me, I don't want to know! (The Doctor gets up to walk around the pod bay.) DOCTOR: Yes you do. Just before Crayford puts this ship into re-entry orbit, these containers will be shot out like pips from a lemon. SARAH: How? DOCTOR: Through the cargo shuttle ejectors. And we'll be in them. SARAH: Oh. DOCTOR: Ask me why. SARAH: Why? DOCTOR: Because they'll reach Earth before the ship. There's no other way we can reach the defense station. SARAH: And what are we going to use for air? DOCTOR: Oh, there'll be enough to last the few minutes in space. I'm more concerned about the efficiency of these retro tubes. (He examines the holes at one end of a pod.) SARAH: Why, don't they work? DOCTOR: Oh, I imagine they'll work well enough for the androids to survive impact, but we could be in for a nasty jolt. SARAH: So, providing we don't burn up on re-entry, and aren't suffocated on the way down, we'll probably be smashed to a pulp when we land. DOCTOR: Exactly! (Sarah makes a worried noise.) DOCTOR: Sarah, you've put your finger on the one tiny flaw in our plan. SARAH: Our plan! It's your plan! DOCTOR: Well, I'm open to suggestions if you've got a better idea. SARAH: (resigned) How long before we start all this? (The Doctor looks worried - we hear a whining noise start.) DOCTOR: Quite soon. They're beaming us through the space-time warp now. [SCENE_BREAK] (Int. Space Command Centre - the real one. We're in a rather spartan Mission Control, complete with a global map showing a projected orbital path. There are three computers with reel-to-reel data storage. Several scientists and other assorted personnel are in the room, including a black woman who appears to be in charge of getting a fix on Crayford's ship.) GRIERSON: Bearing 1-4-3. TESSA: I've got him! (She flicks a few switches on her console.) MATTHEWS: There he is! (He points excitedly at the large map screen.) GRIERSON: Contact. (We get a look at another map screen, with Cornwall and southern Wales visible. A bright point of light over Cardiff Bay is visible, pinpointing Crayford's location.) GRIERSON: Confirmed. (sounding relieved) Well done, Tessa. (He picks up a telephone. In the background, Tessa and Matthews are chatting happily about how nicely the contact is matching the predicted flight path and generally congratulating one another. Grierson gets on the phone.) GRIERSON: (happy, into phone) Colonel Faraday? Ah, hello sir, this is the scanner room. We've picked up Crayford's ship, sir. (pause) Yes, absolutely on the button! (pause) Right, sir! (He hangs up the phone and speaks to his colleagues.) GRIERSON: The old man's coming down. [SCENE_BREAK] (Int. Space Defense Centre - main entrance. There are people here now, going about their ordinary business. The automatic doors slide open and RSM Benton walks in. He meets Lt Surgeon Harry Sullivan.) BENTON: Well, we've searched the area for them, made enquiries in the village. No sign of the Doctor or Miss Smith anywhere. HARRY: Well, he'll turn up when he feels like it. I'm sure there's nothing to worry about. BENTON: Yes, I just hope you're right. HARRY: (cheery) You're a pessimist, Benton! What could possibly happen to the Doctor in Devesham Woods? BENTON: (unconvinced) It's just that, I've never known him leave the TARDIS with the key in it before. (Colonel Faraday strides into the entryway.) FARADAY: Come along, men! (He walks up to Benton and Harry.) FARADAY: (elated) Crayford's just been spotted on the scanners. HARRY: Well that's great, sir! (Harry and Benton follow Faraday into another part of the complex.) [SCENE_BREAK] (Int. Space Command mission control. Matthews is speaking into a radio on the console. Matthews is wearing a red shirt, incidentally.) MATTHEWS: Hello, XK-5, hello, XK-5, this is Devesham Control calling XK-5. Do you read me, do you read me? (Matthews continues repeating the hail as Colonel Faraday, Sergeant Benton, and Harry Sullivan enter the room and start talking to the mission controller, who is clearly elated, and who, incidentally, is named Grierson.) GRIERSON: Right on course. FARADAY: This is a moment for history, Grierson. GRIERSON: (quite happy) Is that so? HARRY: A two year journey... FARADAY: He's been further into space than any other human being. (Harry glances sidelong at Faraday, then shares a long glance with Benton. Meanwhile, the hail is still being repeated.) MATTHEWS: ...this is Devesham Control calling XK-5. Do you read me, do you read me? (He switches to receive, and this time he gets a signal.) CRAYFORD: (on radio) Come in Mission Control. This is XK-5. I'm receiving you loud and clear. MATTHEWS: Okay, XK-5, standby, standby. (Grierson hands a mike to Faraday.) GRIERSON: Sir, would you care to...? FARADAY: (politely) Oh, yes, thank you. (Faraday takes the mike.) FARADAY: Hello, Crayford? Colonel Faraday here. I, ah...well, what can one say at a moment like this except, "Welcome home?" CRAYFORD: (on radio) Thank you, sir. Earth certainly looks pretty good from up here. I've had some problems... (His transmission becomes faint as interference builds up.) FARADAY: What's that? Re-entry? GRIERSON: Not yet, sir... (Grierson starts looking at controls, trying to figure out what it is.) GRIERSON: There's something else coming in on the same path! FARADAY: Something else? GRIERSON: (amazed) Yes, sir... A fireball or something. It's broken into meteorites, look! (We see them on the screen, slowing, moving in over Wales.) [SCENE_BREAK] (Int. rocket pod bay. We see a pod sitting in its launch cradle. There is a humming noise and it drops down through the floor to be launched.) [SCENE_BREAK] (Int. Space Command mission control. Tessa is monitoring the bogies.) TESSA: They're down to 17 thousand metres. FARADAY: Never mind the meteorites. Have we still got contact with the ship? GRIERSON: Just hit the upper atmosphere, sir. Looks like a perfect re-entry path. MATTHEWS: He'll be back in the mess in time for late breakfast! HARRY: No he won't, Matthews. Not after two years in space. MATTHEWS: That meteorite shower's really coming in! BENTON: Yes, but don't they usually burn up before they hit the Earth? MATTHEWS: This lot's not going to. (Matthews looks at his instruments.) MATTHEWS: There's something funny about them... FARADAY: Something funny? MATTHEWS: I swear they're slowing down! [SCENE_BREAK] (Ext. country outside Devesham. Four of the pods are CSO'ed onto the shot, coming in for a rather unconvincing landing. Their retros fire off-camera and they come to Earth amid smoke and noise. When the smoke lifts, there's a pod sitting there. It opens to reveal...the Doctor. He sits up, looking a bit rumpled from the ride. He gets out.) DOCTOR: Sarah? Sarah? No Sarah. (He looks around.) DOCTOR: No Sarah. (He goes off looking for her.) [SCENE_BREAK] (Int. Space Command mission control. Close-up of Colonel Faraday with his mouth hanging open. He's watching the scanner. Benton is watching too. So is everybody. They're waiting for Crayford to radio in. The static clears.) CRAYFORD: (on radio) XK-5 to control. HARRY: (relieved) He's through. CRAYFORD: (on radio) This is XK-5 calling control. TESSA: Devesham Control to XK-5. We're locking on. CRAYFORD: (on radio) Roger, Devesham. TESSA: Ignition minus 30, on my mark. Mark. CRAYFORD: (on radio) Mark thirty. (A video picture of Crayford in his suit at the helm of his ship begins to show.) CRAYFORD: (on radio) AGS reading: 400 plus one. TESSA: Ten seconds to ignition. Mark. CRAYFORD: (on radio) I have ignition, Devesham. Starting descent. MATTHEWS: Altitude: 40 thousand metres...39...38 thousand. Descent velocity: 650 metres per second. FARADAY: (to Harry) He'll be landing in a few minutes. Everything you need, Sullivan? HARRY: (smiles) I've got the tools of the trade here, sir. (He raises his briefcase.) GRIERSON: You're looking good, Commander. CRAYFORD: (on screen) Good from here too. Have you brought some champagne on ice down there? (Everybody smiles to each other; this is going amazingly smoothly.) [SCENE_BREAK] (Ext. Devesham Woods. Sarah is working her way through the bracken. She reaches the TARDIS, standing in a clearing not unlike the one on the Kraal homeworld. The key is still in the lock.) SARAH: Doctor? (She walks up to the TARDIS and calls inside.) SARAH: Doctor? (He's not there either, but she notices a pod sitting a little ways away. She hears a stick break and spins around to look back the way she came. A hand taps her on the shoulder. She spins back only to see...that it's the Doctor, looking strangely emotionless. After a moment, he smiles his toothsome smile. Sarah scowls at him for surprising her.) SARAH: Oh, don't do things like that! DOCTOR: I'm sorry. I had to be sure. You see, there's a replica of you around somewhere. SARAH: Well, my replica wouldn't be as glad to see you as I am. (He smiles faintly. There is a noise like rocket thrusters and both Sarah and the Doctor look up.) SARAH: What's that? DOCTOR: The rocket is coming in to land. SARAH: Well, we've got to hurry if we're going to warn them! DOCTOR: It would suit our purposes more if no one was warned. (We suddenly see that the Doctor has his hand in his jacket, a la Napoleon, and the pod behind him is opening. Sarah sits up inside - another android.) SARAH: (gasps) You're not the real Doctor. (He goes to grab her, but is too slow. She runs off into the forest. The android Sarah gets out of the pod and joins the android Doctor.) ANDROID SARAH: Come. We have much to do. (They head off into the woods, not following Sarah.) [SCENE_BREAK] (Int. Mission Control.) GRIERSON: You are cleared for landing, XK-5. CRAYFORD: (on screen) Roger. Coming down now. TESSA: Coming down 19...500...at 17...400 metres...250...200... MATTHEWS: Slight drift to right. CRAYFORD: (on screen) Correcting three forwards, three forwards. (We hear some engine noise as Crayford executes the manoeuvre. It sounds exactly like an airliner turbofan.) CRAYFORD: (on screen) Easy...easy... MATTHEWS: Docking contact. CRAYFORD: (on screen) Sentencing command override off, engine off... That's it, boys, crack the bubbly! GRIERSON: (to Faraday, with great relief) The XK-5 has landed, sir! FARADAY: Well done! Well done! Come along, Sullivan, we'll go on board! (Everybody breaks out of their tension as the officers leave and Matthews starts offering coffee.) MATTHEWS: Coffee anybody? NAMELESS GUY: Make mine black! MATTHEWS: (to woman) How about you, Tessa? TESSA: Yes, please. GRIERSON: (into mike) Commander Crayford? (The camera switches to inside the rocket, where Crayford sits taking his suit off in front of a CSO screen used to insert a cheap photo of some control panels.) GRIERSON: (on radio) Colonel Faraday and the MO are on their way up now, sir. CRAYFORD: Thanks! I'll be waiting. (As Crayford smiles happily, Styggron steps into the frame. There is dramatic music.) [SCENE_BREAK] (Int. Space Defense Centre, main entrance. The Doctor walks in and stops in front of a UNIT guard - as it happens, it's Corporal Adams.) DOCTOR: Excuse me, can you tell me where I could find the commanding officer? CPL ADAMS: Yes sir, he's in the scanner room. DOCTOR: Thank you. (He starts to leave. Corporal Adams stops him.) CPL ADAMS: Excuse me, sir, could I see your pass? (The Doctor begins excavating his pockets until he finds it. Adams looks it over.) CPL ADAMS: Yes, that's all right, thank you. (He hands it back. The Doctor takes it, then does a double-take as he realizes it's Cpl Adams - presumably the real one this time.) DOCTOR: Is this the first time you've seen me today? CPL ADAMS: (surprised) Yes, sir. DOCTOR: (dead serious) Good. Now, if you do see me again, I want you to report it to me immediately. I'll be with the CO in the scanner room. (He departs, leaving Adams very perplexed.) [SCENE_BREAK] (Int. Mission Control/scanner room. Grierson and Benton are there, and Benton is on the phone.) BENTON: Yes, yes. Make it 8 o'clock outside the Chinese takeaway. And don't be late! (He hangs up.) GRIERSON: (chuckles) You got her well trained. BENTON: Yes, well to be honest with you it's my kid sister. I'm taking her to a dance at the Palais tonight. (The Doctor sweeps into the room.) BENTON: Doctor! Where've you been? We've been looking...DOCTOR: (intense) Where's Harry? BENTON: Mr Sullivan? He's gone up to the rocket with Colonel Faraday. DOCTOR: Call him down. GRIERSON: I can't do that, sir! DOCTOR: Call him down! BENTON: Better do as he says. (Grierson moves to the microphone.) GRIERSON: Hello? (The Doctor takes the mike away.) DOCTOR: Harry? Harry? Can you hear me? HARRY: (os) Hello, Doctor, is that you? DOCTOR: Yes it is. Don't go into that rocket! FARADAY: I don't understand! What the dickens is going on? DOCTOR: Just trust me, Colonel! If you go into that rocket, your lives will be in deadly danger. FARADAY: (os, scoffs) Chap's insane. HARRY: (os, quiet) I think we ought to do as he says, Colonel. DOCTOR: Harry, bring the lift down. I'll explain it all then. FARADAY: (os) Very well, Doctor, but the explanation had better be good! (Pause. Grierson watches the console.) GRIERSON: The lift's started down again, sir. (Matthews enters the room again.) MATTHEWS: Mr Benton? BENTON: Yes? MATTHEWS: Could you spare a minute, please? (They leave together.) DOCTOR: (to Grierson) What controls the angle of your radar dish? GRIERSON: (pointing) This one here, sir. DOCTOR: Give me a pen. (He does and the Doctor begins sketching on a notepad.) [SCENE_BREAK] (Int. hallway of space defense centre. Corporal Adams bursts through a door, looking very angry.) CPL ADAMS: What is going on here? (Matthews comes up behind him from the other side of the door and clobbers Adams on the back with both his hands locked together. Adams goes down, falling unconscious on top of the unconscious Benton. Another Benton walks up next to the android Matthews.) ANDROID BENTON: Have them taken away. [SCENE_BREAK] (Int. scanner room. The Doctor has sketched quite a complicated schematic. He rips it off the pad and hands it to Grierson.) DOCTOR: Could you do that? GRIERSON: It's possible. It would take a bit of time, though. I'd have to re-jig about...eleven circuits there. DOCTOR: (very serious) All right. Well then, get about it. GRIERSON: You can't... DOCTOR: Tell no one what you're doing. GRIERSON: You can't point the radar dishes down here, sir! They'd jam every radio and electronic circuit for miles. There'd be chaos. DOCTOR: (tired) Nothing like the chaos there'll be if you don't do it, Grierson. (Harry and Faraday return.) FARADAY: Doctor! What the devil's going on? DOCTOR: An invasion of Earth is going on, Colonel. FARADAY: What?! DOCTOR: Let's get to your office. You've got some important phone calls to make. Crayford's sold you out to the Kraals. FARADAY: Kraals? Never heard of them! (They storm out together as Grierson contemplates the Doctor's schematic sketch.) [SCENE_BREAK] (Int. space defense centre, entering the CO's office.) HARRY: Have you actually seen these androids, Doctor? DOCTOR: Indeed I have. FARADAY: (righteously indignant) I'll not have my command infiltrated by aliens! HARRY: (quietly) Sir, they may already be among us. DOCTOR: They made replicas of you and Harry, Colonel. (Faraday sits down behind his desk.) FARADAY: Of me?! Confounded cheek, how dare they! HARRY: I think I should run a complete medical check on everyone. FARADAY: Good idea, Sullivan. (nods) That'll nail 'em, eh, Doctor? DOCTOR: Yes, but it would take too long. We can use this. (The Doctor takes a device out of his pocket, a white box with a single red light.) HARRY: What's that? DOCTOR: It's a robot detector. It lights up in the presence of androids. (It lights up.) FARADAY: Thing must be faulty. DOCTOR: (calmly) I don't think so. I see I was just too late. ANDROID DOCTOR: (os) A pity you had to find out. (The real Doctor spins around in shock to see his duplicate standing in the doorway pointing a gun at him.) ANDROID DOCTOR: We didn't want any shooting until our takeover was complete. DOCTOR: (cheery) Hello, Doctor! We've been waiting for you. (He steps forward.) ANDROID DOCTOR: Stand back, Doctor! DOCTOR: You know, the resemblance is astonishing. For a moment, I thought I was seeing double. (Suddenly, the Doctor slams the door shut on his duplicate, dashes past the androids Harry and Faraday and leaps out the window.) (CUT TO outside, in the car park. The Doctor rolls to a stop in a shower of broken window glass. Sarah appears around a corner in the distance.) SARAH: Doctor! Doctor, this way! (He picks himself up and runs towards her. They flee amid gunfire from the android Doctor's pistol.) (CUT TO int. CO's office. Android Faraday is on the facility intercom. We see a shot of a young woman, an office worker, looking up as she hears the announcement. We also see the android Benton, listening.) ANDROID FARADAY: Attention, attention. It has been confirmed the Doctor is attempting to sabotage our defense system. He is at large somewhere inside the complex. (CUT TO a shot of Sarah and the Doctor fleeing outside. They pause behind a corner.) ANDROID FARADAY: (os) Saturation search will begin at once. He is armed and dangerous, and all personnel have the authority to shoot on sight. That is all. SARAH: (breathing heavily) So the androids have taken over. DOCTOR: Looks like. SARAH: What about the real Harry and Colonel Faraday? DOCTOR: They must be up there in the rocket with Styggron. (They sidle towards the edge of the building and peer across at the rocket. It doesn't look anything at all like the rocket that appeared in the launch sequence.) SARAH: We've got to help them somehow! DOCTOR: Our only chance is to stop the androids before they take over the complex. (He moves to leave.) SARAH: (startled) Where are you going? DOCTOR: To the scanner room. You stay here, Sarah. (He sprints away.) [SCENE_BREAK] (Shot of the scanner room. Grierson is hard at work.) [SCENE_BREAK] (Int. space defense centre, main entrance. The Doctor enters and is stopped by android Benton, who raises a gun at him.) ANDROID BENTON: Hold it, Doctor. DOCTOR: (deprecating) Don't be a fool, Benton, I'm one of you! Didn't you hear the Colonel just now? The Doctor's not here, he's at large somewhere in the complex! (The android Benton lowers the gun.) ANDROID BENTON: (abashed) Oh yes of course sir. I'm sorry sir. DOCTOR: It's all right, Benton, but keep your wits about you. Nobody knows who's who around here. (The Doctor proceeds on to the scanner room.) [SCENE_BREAK] (Ext. rocket gantry. It's a red metal staircase against a CSO backdrop. Sarah's climbing up it. It's windy.) [SCENE_BREAK] (Int. scanner room.) DOCTOR: Have you finished, Grierson? GRIERSON: Almost there, Doctor. DOCTOR: We haven't got a second to lose, man. [SCENE_BREAK] (Int. space defense centre, main entrance. The android Doctor walks in and is stopped by android Benton with a raised gun.) ANDROID BENTON: Hold it, Doctor. ANDROID DOCTOR: Don't be a fool, Benton, I'm one of you. (Benton opens fire. The bullets have no effect on the android.) ANDROID DOCTOR: (quiet and dangerous) Satisfied? ANDROID BENTON: (confused) But...but I thought you were...he passed me just a minute ago. ANDROID DOCTOR: Which way did he go? ANDROID BENTON: (confusion resolved) To the scanner room. (The android Doctor heads off.) [SCENE_BREAK] (Int. scanner room. Grierson is working hard on a circuit board, pressing components into their sockets.) GRIERSON: Ah! I've done it. (He puts the circuit board in.) (CUT TO Space Defense Station model shot. The dish antenna slowly moves down.) (CUT back.) GRIERSON: All we have to do now is switch on the power.DOCTOR: (os) Good. (Grierson goes to switch on the power, but a shot rings out and he falls to the ground. We cut to see the Doctor whirl around to face his android duplicate.) ANDROID DOCTOR: A clever way to jam android's circuits, but not quick enough. (Crayford enters, having just come down from the rocket.) CRAYFORD: What's going on? ANDROID DOCTOR: The Doctor has interfered in our plans for the last time. CRAYFORD: But Styggron promised me there would be no killing. ANDROID DOCTOR: Fool. Do you really think the Kraals will spare humanity? Styggron has a virus in your ship that will destroy every man, woman and child in the world. CRAYFORD: (nervous, not wanting to believe it) Styggron wouldn't do that! He, he's a surgeon! A genius! Look what he did for me! DOCTOR: He did nothing for you, Crayford. Absolutely nothing at all. Except brainwash you. CRAYFORD: (quiet) That's not true. DOCTOR: You were hijacked by the Kraals, Crayford. Nothing went wrong with your rocket, Crayford. You weren't even injured. Take off the eye patch and look for yourself. (Crayford slowly turns and walks to a mirror on the wall. Hesitantly, he reaches up to his face, touches the eye patch - and pulls it sharply away. Underneath is a perfectly good eye. He closes both eyes as he realizes that the Doctor's been right all along. Furious, he storms back towards the rocket access. The Doctor takes advantage of the distraction and knocks the gun away from the android. The 'droid is stronger, though, and throws him down the short steps to the lower level of the room. The android Doctor presses a button to activate an alarm.) [SCENE_BREAK] (Int. hallway of space defense centre. The android versions of Harry and Benton hear it.) HARRY: The scanner room! (They set off running.) [SCENE_BREAK] (Int. scanner room. The Doctor sits up and fixes his eyes on the radar power switch. He picks himself up and heads for it, but the the android Doctor leaps down over the upper console and tackles him. A fight breaks out between the Doctor and his duplicate. The android has the upper hand and throws the Doctor around a few times until he lands next to Grierson, who is not dead after all, but trying to keep out of the way of the combatants. The android grabs a chair to kill the Doctor with, and the androids Harry, Faraday and Benton enter the room. But before they can kill him, the Doctor hits the switch and the 'droids all freeze. The Doctor slumps limply back, relieved.) [SCENE_BREAK] (Int. rocket pod bay. All the launch cradles are empty now. Sarah enters in search of Harry and Colonel Faraday.) SARAH: Harry? (She closes the door behind her.) HARRY: (os) Sarah? Sarah, where...? SARAH: Harry! (She runs across the pod bay and we see Harry and Faraday all tied up and sitting in a sunken corner of the pod bay.) HARRY: What's going on? SARAH: It's a long story. For a start, you've got a very nasty twin. HARRY: Twin? [SCENE_BREAK] (Int. scanner room. The Doctor is checking up on Grierson. Grierson is clutching his shoulder - presumably that's where the bullet went.) DOCTOR: You all right? GRIERSON: Yeah, I think so, Doctor. DOCTOR: Good. (sighs with relief) Where's Crayford? GRIERSON: He went back to the rocket. DOCTOR: Did he? (He puts his hat on.) [SCENE_BREAK] (Int. rocket pod bay. Sarah has untied Harry's wrists and is working on Faraday's while Harry works on freeing his own feet.) FARADAY: It's all very well, but what are these androids? SARAH: Shhh! I keep telling you! They're robots controlled by Styggron. (Styggron enters, holding the virus and his ray gun.) STYGGRON: (delighted) The enterprising Earth girl! No! Don't move! The sensors indicated an intruder. I hardly expected to find it was you. SARAH: No, I suppose you thought I was still a prisoner on your planet. STYGGRON: I know the Doctor managed to escape, but you must indeed have a charmed life. SARAH: What are you getting at? STYGGRON: You were to have been the first human victim of the billions to be destroyed by this virus. (He holds up the virus capsule.) STYGGRON: How did you escape death? (Sarah does not respond. She just stares at Styggron.) STYGGRON: Did you not drink the water? SARAH: Water? CRAYFORD: (os) Styggron! (Styggron turns to see Crayford standing in the door, eye patch gone and seeing through both eyes. He looks majorly pissed.) CRAYFORD: You have betrayed me! STYGGRON: Betrayed you? I used you, Crayford, as I used the androids. But you are no longer of any value. (Crayford jumps Styggron. The virus capsule falls to the ground. They struggle for a moment, but then Styggron throws Crayford off and shoots him with the ray gun. Crayford falls to the ground. As Styggron inspects his handiwork, the Doctor enters the rocket right behind him.) DOCTOR: Excuse me. (Styggron spins, but not fast enough. The Doctor nails him with a bit of Venusian Aikido and throws him right onto the virus capsule, which shatters. The green goop inside smears all over Styggron's face. Styggron screams and the Doctor instinctively moves to help, but Styggron fires at him. The Doctor goes down clutching his shoulder, falling right down among Sarah, Harry, and Faraday.) SARAH: Doctor! Oh, no! DOCTOR: (os) Don't waste any tears on him, Sarah. (They look up to see the Doctor in the entryway.) DOCTOR: He's only an android. SARAH: (standing) An android? DOCTOR: Yes. My replica. I reprogrammed it to confuse Styggron. (They look down to see the android's skin fade away, revealing the exoskeleton beneath.) SARAH: Please, don't ever do anything like that again. DOCTOR: (chuckles) Come on. (They all leave the rocket.) [SCENE_BREAK] (Ext. Devesham Woods, close-up of what looks a lot like a Purple Loosestrife flower stalk. Pull back to see Sarah and the Doctor strolling calmly through the woods.) SARAH: Oh, how could we ever have been fooled? DOCTOR: How do you mean? SARAH: This really is Earth! DOCTOR: (mock seriousness) Are you sure? (Sarah grins and follows him onward. They reach the TARDIS and the Doctor opens the door for Sarah.) DOCTOR: After you? SARAH: (shakes her head grinning) I'm going home. And I'm going by taxi! DOCTOR: Oh. (grins) I'll make you an offer. I'll take you home! SARAH: (smiling) How can I refuse? (She goes into the TARDIS, which dematerializes.) (Cue music, cut to credits.)
The Android Invasion - part 4
