1. EXT. PARADISE TOWERS

(An exterior view of the Towers, high up in the sky. The glass walls and windows of the Towers reflect the fluffy white clouds hanging in the sky.)

2. INT. THE BASEMENT

(The Cleaner pushes the Chief Caretaker towards his "pet" represented by the neon lights through the "No Entry" door.)

VOICE: You have no choice. I am Kroagnon, the Great Architect, and I will put an end to you and everyone in Paradise Towers.

(The Chief is pushed forward by the Cleaner and into a machine. An opaque cylinder begins to descend on him and obscures him from view. As it does so, he lets out a loud scream. The Doctor and the Kangs come out from their hiding place and watch this happen.)

BIN LINER: Ware Cleaners!

THE DOCTOR: Back to the lift.

(f*re Escape is hesitant, thinking she can use her w*apon on a Kang, but the Doctor gestures for them to run.)

f*re ESCAPE: Wait, Doctor.

THE DOCTOR: Back!

(f*re Escape fires her w*apon, hitting a Cleaner, but it has no effect on it. Taken off guard, another Cleaner appears. With its claw it grabs the Doctor by the throat and proceeds to strangle him.)

DRINKING FOUNTAIN: Doctor! Now.

(She fires her w*apon and the arrow hits the Cleaner, causing a malfunction, and thus it loses its grip on the Doctor. The Doctor and the Kangs quickly run for the exit door and it closes, placing a barrier between them and the Cleaners. Back in Kroagnon's lair, the large opaque cylinder rises, revealing what used to be the Chief Caretaker. His skin now has a silvery sheen and his clothing looks clean and shiny. Kroagnon now inhabits the Chief's body. He steps out from the machinery and moves to address the Cleaners who gather around him.)

KROAGNON: Attention all Robotic Cleaners. Attention all Robotic Cleaners. At last Kroagnon can leave the basement prison they trapped his bodiless brain in and return in this borrowed body to the corridors and lifts of his own creation. They buried me away because I wanted to stop them using the Towers. And now you and I will destroy them.

3. INT. THE STREET

(The Doctor and the mixture of Kangs race down the street. The Doctor is clearly out of breath lagging behind.)

THE DOCTOR: Just a moment, please stop! Please! The immediate danger's over. And I wouldn't mind getting my breath back.

(The Doctor sits down on an old crate at the side of the corridor. The three Kangs - Drinking Fountain (Blue Kang Leader), f*re Escape (Red Kang Leader) and Bin Liner (Red Kang) - kneel down beside him. A fourth Red Kang stands guard at the end of the corridor.)

DRINKING FOUNTAIN: The Doctor really is ice hot.

THE DOCTOR: Very hot!

DRINKING FOUNTAIN: Not a yawny Oldster.

THE DOCTOR: Now, you understand the dangerous position we're in. We must gather all the Kangs together.

f*re ESCAPE: And is the Chief Caretaker really unalive?

THE DOCTOR: As himself, yes. But you saw what happened. Up till now Kroagnon's simply been a mind without a body, as your parents must have left him. However, I fear he may have spent his time down there devising a way of performing Corpoelectroscopy - a way of transplanting his brilliant brain to some host body.

BIN LINER: And what's the come out, Doctor?

THE DOCTOR: Oh, I can't be certain. But Kroagnon won't want to stay locked up in his basement much longer. He's bound to show himself in one form or another.

4. EXT. FLOOR 304 / THE POOL

(Pex is sitting at the side of the pool whilst Mel bobs around in the water, enjoying herself.)

MEL: Oh, the water's really lovely. You really ought to come and join me, Pex. It'll do you the world of good. There's really nothing to be frightened of.

(Mel fails to see the Yellow Robotic Crab-like Pool Cleaner as it comes up behind her. It grabs hold of her and she lets out a scream. Pex is alerted and jumps to his feet, uncertain of what to do.)

5. INT. RED KANG HEADQUARTERS

(The hideout is bustling with activity. The Doctor rests against a large blue barrel. The Red and Blue Kangs are present.)

THE DOCTOR: It's taking over the building floor by floor.

(Bin Liner is on the Talky phone.)

BIN LINER: Return to Red Kang Base and Ware Cleaners! Build High for Happiness.

(She replaces the receiver onto it's position on the Drinking Machine.)

THE DOCTOR: Is f*re Escape going to join us?

(Bin Liner nods.)

THE DOCTOR: Are all the Kangs here? Red? Blue?

DRINKING FOUNTAIN: Yes. Except for those...

THE DOCTOR: Those who've been made unalive. Yes. Well, when f*re Escape gets here we must all make for the Great Pool in the Sky.

6. EXT. FLOOR 304 / THE POOL

(The Yellow Pool Cleaner is attempting to drag Mel under the water. Her head goes under a few times but she struggles to remain above the surface of the water. Pex runs around the side of the pool in a state of confusion and panic.)

MEL: Pex, do something!

PEX: But what should I do?

MEL: Anything!

(The Cleaner bobs up and down in the water thr*at Mel with its claws and mechanical tendrils that are wrapped around Mel's body.)

PEX: Help! Help!

MEL: Can't you think of anything else?

(Again the Cleaner pulls Mel beneath to the surface of the water. When she struggles back up again, she makes a lunge in the direction of Pex, reaching for his g*n.)

MEL: Quick. Give me that!

(She takes the g*n from Pex and splashes her way out of the pool as the Cleaner advances after her. She turns and fires directly at it causing an expl*si*n. The Cleaner buzzes and crackle and sinks to the bottom of the pool. Mel stands panting on the edge of the pool with Pex.)

PEX: Mel, I did warn you.

(Mel turns to look at Pex in frustrated disbelief.)

7. INT. THE CARETAKERS' HEADQUARTERS

(The Deputy Chief Caretaker stands in front of the bank of monitor screens as he addresses his fellow caretakers.)

DEPUTY CHIEF CARETAKER: Attention all Caretakers. Regulation ZZZ is now in operation. This overrides all other rules and regulations. I repeat, this overrides all other rules and regulations. All Caretakers to act with extreme caution and get back here as fast as they can.

(The monitor screens display various Caretakers running down the corridors in response to his instructions.)

8. EXT. FLOOR 304 / THE POOL

(Mel and Pex are sitting on a lounger at the side of the pool. Mel has dried off and put her clothes back on. Pex looks very glum.)

MEL: Pex.

PEX: What?

MEL: I'm sorry.

(She is distracted by a sound coming from the other end of the pool - behind a curtain.)

MEL: What's that?

PEX: Where?

MEL: Well there's a rustling sound coming from over there.

PEX: I only checked it a few minutes ago.

MEL: Shall I go?

PEX: If you want.

(Taking a deep breath, Mel puts her towel aside and walks as nonchalantly as possible towards the curtained-off area. Pex cautiously follows her, getting his g*n out just in case. She pulls aside the curtains to see nothing there.)

PEX: Nothing there?

MEL: No.

PEX: Sure?

MEL: Of course. See for yourself.

(Suddenly the Doctor bursts through the curtain, startling both Pex and Mel. Mel gasps but is then relieved.)

MEL: Doctor!

THE DOCTOR: I'm sorry to give you such a shock, Mel, but this is where the Cleaner service lift appears to come out.

MEL: Oh, Doctor, it's so good to see you!

THE DOCTOR: And you, Mel, and you!

(The Doctor and Mel hug. The Doctor notices Pex and reaches out his hand and doffs his hat.)

THE DOCTOR: Um, how d'you do?

MEL: This is Pex.

THE DOCTOR: Ah. I believe you've met my friends before.

(The Doctor steps back and pulls the curtain back to reveal the Kangs. Pex takes up a defensive stance and eyes them suspiciously.)

9. INT. THE STREET

(Smoke starts to fill the corridor. A Caretaker appears at the end of it, clutching his throat and coughing. He falls to the ground d*ad. Kroagnon, inhabiting the Chief Caretaker's body, walks awkwardly down the corridor followed by a Cleaner that belches out smoke.)

KROAGNON: Search hard, My Cleaners, search hard. Bring them all out! All the nasty human beings! The Caretakers! The Residents! The Kangs! All of them! We'll be back to collect the rubbish later.

10. EXT. FLOOR 304 / THE POOL

(The Kangs are sitting in a united group along the side of the pool with Pex alone at the end. The Doctor and Mel are pacing up and down at the head of the pool.)

MEL: Imagine building this beautiful pool and filling it with mechanical K*llers.

THE DOCTOR: The rest of the Towers would have been like this pool if he'd had his way. A k*ller in every corner.

MEL: And you're sure Kroagnon's been let loose again?

THE DOCTOR: Oh, very much so. But we know so little about his plans. He had years to brood over what he wants to do. But we've no time to come up with a counter plan.

(f*re Escape moves over to Pex to taunt him, with the other seated Red and Blue Kangs willing her on.)

f*re ESCAPE: Did Mel make the creature unalive for you?

DRINKING FOUNTAIN: And stop you being taken to the cleaners?

(Pex nods his head shamefully.)

f*re ESCAPE: Then Mel is a Kang after all.

(They all look around at the Doctor and Mel conversing at the other end of the Pool.)

PEX: I'll show you all. I will put the world of Paradise Towers to rights.

BIN LINER: Oh, yes?

PEX: Yes!

f*re ESCAPE: You're a cowardly cutlet, Pex. You will always hide, always.

(All the Kangs laugh at Pex. Mel and the Doctor watch the unruly group.)

MEL: They shouldn't treat him like that.

THE DOCTOR: That's Paradise Towers in a nutshell, I'm afraid. The Red Kangs didn't trust the Blue Kangs. And none of them trusted the Caretakers. And the Rezzies, from your account, prey on whoever they can and trust no one either. And all of them despise poor old Pex. Oh, the Great Architect must be delighted. How are we going to unite the people of Paradise Towers to defeat him?

MEL: We'll find a way. We have to.

(The Doctor looks despairingly at Mel. All through their conversation, the Kang chants of "He's a Cowardly Cutlet" have been building, directed at Pex. Unable to take anymore, Pex storms off in the direction of the way out. He walks past the Doctor and Mel. She goes to follow him.)

MEL: Pex, don't go. Pex!

(All of those gathered around the pool are stunned into silence and stillness at the unexpected arrival of three Rezzies, lead by Maddy. She steps timidly forward to address them all.)

MADDY: I... that is we... we the Rezzies... the remaining Rezzies that is, want to talk to you all. I think we may need your help.

11. INT. THE CARETAKERS' HEADQUARTERS

(The Deputy Chief Caretaker sits alone, solemnly staring at the floor. The main door to the room opens with a hum and what the Deputy thinks is the Chief walks in - Kroagnon. The Deputy jumps up looking pleased.)

DEPUTY CHIEF CARETAKER: Well, Chiefy, I thought you were lost. I...

(He stops as he sees two Cleaners through the doorway behind the Chief (Kroagnon). He notices the Chief's slightly odd appearance - he has a silvery sheen to his face and clothing. He starts to advance awkwardly towards the Deputy.)

KROAGNON: The Towers have become appallingly dirty.

DEPUTY CHIEF CARETAKER: Sorry?

KROAGNON: The whole place is polluted with flesh, living flesh.

DEPUTY CHIEF CARETAKER: Flesh? Did you say living flesh?

KROAGNON: Yes.

DEPUTY CHIEF CARETAKER: But Chief, you...

KROAGNON: Deputy, may I remind you that there is a rulebook and the rulebook says that the orders of the Chief Caretaker are never to be questioned.

DEPUTY CHIEF CARETAKER: Yes, yes. Of course, of course, Chief. Unless...

KROAGNON: Unless...?

(Kroagnon starts to advance menacingly towards the Deputy, who starts to back away in the direction of the door.)

DEPUTY CHIEF CARETAKER: Well, I think you may recall that there are certain cases specified when the rulebook can be overridden, and that is when the Chief Caretaker...

KROAGNON: Yes...?

DEPUTY CHIEF CARETAKER: ...just isn't the Chief Caretaker.

(The Deputy Chief Caretaker turns around and runs out of the door. He leaps over the Cleaners that are in the way and races down the corridor. Kroagnon goes to the door and addresses the Cleaners.)

KROAGNON: Leave him. Leave him. We'll clean him up when we clean up all the others.

12. EXT. FLOOR 304 / THE POOL

(The Doctor, Mel, Pex, the Red Kangs and the Blue Kangs are all gathered around to hear the information provided by the Rezzies who are seated on a sofa.)

MADDY: The Cleaners have reached about floor 115 now. All the Rezzies, that can, have moved up to the higher floors, but not everyone was quick enough.

(The Doctor points to the map on the table in the centre of everyone so that they can all see how high the Cleaners have reached.)

THE DOCTOR: And you're sure that person ordering the Cleaners to do this looks like the Chief Caretaker?

(Maddy simply nods.)

BIN LINER: But he's unalive, Doctor. We saw it.

THE DOCTOR: Exactly. So the Great Architect has taken over his body.

(f*re Escape leans forward to cast accusations.)

f*re ESCAPE: Why should we believe her? Rezzies are full of untruth and Kangs. Rotten old rubber neck...

THE DOCTOR: Please, please, be quiet. Be quiet.

(He hushes the Kang grumblings and reassures Maddy to continue as she consults, in hushed tones, with her fellow Rezzies.)

MADDY: Of course, I know that we residents have not always been as neighbourly as we might have been. But some have been worse than others. And the worst have gone... down the waste disposal chute.

(The Doctor looks disapprovingly at this. Mel and Pex exchange looks, remembering the event described.)

MADDY: But those of us who are left want to let bygones be bygones. We're all in danger now and well, we're very sorry for what we did and we won't do it again. If we all survive that is. We need each other's help.

THE DOCTOR: Well, you Kangs, what d'you say to that?

(Drinking Fountain and another Blue Kang and f*re Escape and Bin Liner, representing the Red Kangs, get into a secret huddle to discuss, whilst the others wait. The huddle breaks up and they address the group.)

BIN LINER: I won't say Rezzies are Ice Hot but yes she's not telling untruths. And yes, we'll help each other.

THE DOCTOR: All agreed? Pex?

f*re ESCAPE: Don't ask him. He's a cowardly cutlet.

THE DOCTOR: f*re Escape!! Pex?

(Pex waits for silence and grimly nods his head.)

f*re ESCAPE: We work with Rezzies - no to-do. We work with Pex - no to-do. But the Caretakers?

(All the Kangs get to their feet to proclaim as one voice.)

KANGS: Never, ever!!!

(Suddenly they have to spin around as they are interrupted by the subtle coughing of the Deputy Chief Caretaker who stands behind them.)

DEPUTY CHIEF CARETAKER: Excuse me. I'm sorry to intrude like this, but I wondered if I might have a word with you all.

13. INT. THE CARETAKERS' HEADQUARTERS

(Kroagnon stands at a transparent map of Paradise Towers and, with a highlighting marker pen, he marks the last floor that Cleaners have reached.)

KROAGNON: 170. All the messy creatures will be moving up to the swimming pool zone on floor 304. Luckily they won't have time to make it too untidy before I destroy them. I have nothing to fear. Nobody knows my Paradise Towers better than I do.

(He sits down at the desk and watches blankly at the monitor screens displaying the Cleaners busily going about their k*ller sprees.)

14. EXT. FLOOR 304 / THE POOL

(Everyone stands ready, awaiting the planning process. The Doctor checks his watch and pockets it again.)

THE DOCTOR: We have very little time, so we must think clearly. Now Kroagnon, as we now must call the Chief Caretaker, is firmly installed in your headquarters. Am I right, Deputy Chief?

DEPUTY CHIEF CARETAKER: Yes, Doctor.

THE DOCTOR: So we must find a way of getting him out again.

BIN LINER: Set a trap for him!

THE DOCTOR: Precisely.

MADDY: We used to do that a lot with the rats.

MEL: But what about the Cleaners?

THE DOCTOR: First, we must immobilise as many as we can.

DEPUTY CHIEF CARETAKER: Doctor?

THE DOCTOR: Yes?

DEPUTY CHIEF CARETAKER: I know it's against the rulebook to say this, but I suppose these are exceptional circumstances.

THE DOCTOR: They could be described thus, yes.

DEPUTY CHIEF CARETAKER: Well, on the 245 Sodium Street, Corridor 75, there's a secret emergency supply kept for pest going out of control.

MEL: An emergency supply of what?

DEPUTY CHIEF CARETAKER: expl*sives.

MEL: That'll do it.

f*re ESCAPE: Ice Hot!

BIN LINER: With expl*sives and arrogance we can blow out the Cleaners, no problem.

DRINKING FOUNTAIN: Send the Cleaners to the Cleaners.

ALL: Yes!!

(They all laugh.)

MADDY: Most of the Rezzies make table cloths. We could throw them over the Cleaners to slow them down for you to sh**t.

f*re ESCAPE: Ice Hot, Maddy!

THE DOCTOR: (to Mel) We seem to be getting somewhere at last.

(Everyone seems jubilant at there ideas, there is lots of merriment and clapping.)

15. INT. THE CARETAKERS' HEADQUARTERS

(Kroagnon continues to make his marks on the transparent map.)

KROAGNON: 163. Time to see what the human garbage is up to in the swimming pool zone.

(He moves to the desk and activates a control. One monitor screen goes blank and the computer voice speaks out.)

COMPUTER VOICE: By express order of the Great Architect, surveillance of the swimming pool is not allowed. Not allowed. 

(Kroagnon growls with anger.)

16. EXT. FLOOR 304 / THE POOL

(The inhabitants of Paradise Towers in the swimming pool area are so overjoyed at their ideas they forget the urgency of the situation and need the Doctor to calm things.)

THE DOCTOR: Please! Please! We must move on to the main problem.

(As silence is regained, the Doctor starts to wander around the pool to ponder. Bin Liner and f*re Escape follow him.)

THE DOCTOR: How to persuade Kroagnon to leave his safety and come to a place of our choosing where we can trap and defeat him.

DEPUTY CHIEF CARETAKER: He'll never leave there until we're all wiped out. We'll never manage to break. I should know that.

THE DOCTOR: Well there is a way that might just work.

f*re ESCAPE: What's that, Doctor?

THE DOCTOR: Well you see, Kroagnon is undoubtedly a very clever and very proud being, and like many clever and proud beings likes to be appreciated by his equals. Now, I think if he had the chance to meet such a person, he would leave his lair to do so. 

MEL: Doctor, you're not going to go and...

THE DOCTOR: I've no choice, Mel. I mean, in all honesty, I am the only obvious candidate.

MEL: You'll go out there and show yourself and be k*lled.

THE DOCTOR: Oh no, no, no. That would be extremely futile. I will allow myself to be seen, and then somebody will go to Kroagnon and offer to lead him to me - right into our little trap. Now that person has a far more difficult and dangerous mission than I.

(Everyone looks around awkwardly and goes silent until one person speaks out.)

PEX: I will go to Kroagnon. I am Pex and I am the...

f*re ESCAPE: A Cowardly Cutlet.

(All the Kangs laugh raucously. Pex is hurt but Mel looks on encouragingly.)

PEX: Well you all have tasks to do. Caretakers, Residents, Kangs, why should only Pex be left out. Pex the trained fighting machine. Pex the only...

BIN LINER: The scaredy cat.

(Again their riotous laughter silences Pex.)

MEL: Pex, are you sure you want to do this?

PEX: Yes, I am.

THE DOCTOR: So be it.

17. INT. THE CARETAKERS' HEADQUARTERS

(The monitor screen continues to display the Cleaners going about their task of destruction. Kroagnon looks at his map but is interrupted by a bing from the control desk. Suddenly a screen comes to life and shows the Doctor's face. Kroagnon walks towards it.)

THE DOCTOR: Hello, there, Kroagnon. This is the Doctor speaking. I don't believe we've met, though no doubt you've heard of me.

(Kroagnon just growls at the arrogance.)

THE DOCTOR: I thought so. Anyway, I'd heard so much about Paradise Towers I thought I'd come and take a look and, believe me, I'm very disappointed. It displays exactly what everyone says is your usual failure as an architect - not making allowances for people. Still, I'm sure if we managed to work together, we might just about make this place habitable. I've a few ideas which I might give to you if you can be bothered to listen. Bye for now.

(The Doctor's screen goes black and Kroagnon again growls with anger.)

18. INT. THE STREET

(A Cleaner moves into yet another corridor to gas yet more unfortunates. Maddy appears from one of the flats to address it. Behind Maddy are two other residents. It stops in its tracks to hear here speak.)

MADDY: Oh, excuse me. Excuse me. I hope you don't mind my mentioning it, but I think you missed some rubbish in the street back there.

(The Cleaner starts to turn around to return to the previous corridor.)

MADDY: Charge!!

(When its back is turned, Maddy ducks down and the two other residents rush forward and throw a table cloth over the Cleaner's eyes, blocking its vision. They then run off, and Drinking Fountain appears in another doorway and aims a bolt from her w*apon, hitting the Cleaner. The Cleaner explodes and then falls silent.)

19. INT. THE RED KANG HEADQUARTERS

(As the Kangs busy themselves gathering together essential pieces of equipment and setting up the expl*sive around the room, the Doctor and Mel are talking with Pex to prepare him.)

THE DOCTOR: Now, are you clear what you have to do, Pex?

MEL: And you are sure you want to go through with it?

PEX: I won't be unbrave again.

THE DOCTOR: Remember, Pex, you must get him out of the CARETAKERS' HEADQUARTERS as quick as you can so that he doesn't see what's happening to the Cleaner. But then, once he's out, take as long as you can. We need time, no heroics, just a cool clear head.

PEX: I can manage.

THE DOCTOR: Good luck, Pex.

(The Doctor shakes his hand and then walks off leaving Pex with Mel.)

MEL: I've been asked to give you this, Pex. It's a Kang bracelet. They wanted to give it to you. They think you're not a scaredy cat any longer but a real Kang. Good luck, Pex.

(She places the bracelet on his wrist and then kisses his cheek. He looks embarrassed. He gives Mel his g*n.)

PEX: You take this, Mel. Can't use it this time.

(f*re Escape, Bin Liner and Mel watch Pex earnestly leave. Bin Liner hands him a stick of expl*sives.)

20. INT. THE STREET

(Another cleaner moves smoothly into the corridor but is confronted by Drinking Fountain and her w*apon. She fires and yet another Cleaner is dispatched. Residents, Caretakers and Kangs join her as she celebrates its immobilising.)

DRINKING FOUNTAIN: Come on, on to the next one.

(They all move off, following here from the corridor, leaving the smoking remains of the Cleaner.)

21. INT. THE CARETAKERS' HEADQUARTERS

(Pex is displayed on one of the monitor screens as he boldly addresses Kroagnon.)

KROAGNON: So you say you could lead me to this so-called Doctor who dares to mock me?

PEX: Yes, he and the other... mobile rubbish have found a place to hide that they think you don't know about. And they're there planning ways of resistance. 

KROAGNON: If you deliver me this Doctor, I'll give you a safe way out.

22. INT. THE RED KANG HEADQUARTERS

(Mel descends the stairs into the room and goes to see the Doctor. Other Kangs are busying around with the expl*sives.)

MEL: Doctor?

THE DOCTOR: Yes?

MEL: The door's nearly back in place anyway but they're having trouble with the fortamoliscope (sic) opening device.

THE DOCTOR: I better give them a hand. See what you can do to help the Kangs down there. Oh, and Mel, don't forget to leave the escape hatch uncovered so that I can make my exit.

(He makes his way to the main entrance door and passes Bin Liner by its side.)

THE DOCTOR: Oh I just hope that Pex doesn't lose his nerve and hurry. Otherwise it won't be Kroagnon who's caught in a booby trap, it'll be us.

23. INT. THE SQUARE

(Various Kangs are splattered around the square, out of sight from the approaching Pex and Kroagnon. Two Cleaners follow them.)

KROAGNON: This is not some trick is it?

PEX: No! No!

KROAGNON: I've only just began to enjoy walking around my marvellous Towers in this body and I wouldn't deal very kindly with anybody who was stupid enough to lay a trap for me.

(They stop just inside the square. Pex looks anxiously aside. Kroagnon taps Pex on the shoulder and startles him.)

KROAGNON: Not frightened, are you?

PEX: I... I think we ought to hurry, Great Architect. Please, let's hurry.

KROAGNON: As you wish.

(Pex walks off. Kroagnon goes to follow him but senses something around him. He turns but sees nothing behind him except for the TARDIS sitting in the corner covered in wallscrawl. He walks onwards, still awkwardly as he cannot quite handle the control of the Chief's body. The two Cleaners follow smoothly after him. When they have gone, the Kangs on the walkway above come from hiding and await a signal from below. A Kang appears and tells them to move on. They leave the square. Drinking Fountain goes to the talky phone in the square and contacts the others.)

DRINKING FOUNTAIN: They're on their way.

24. INT. THE RED KANG HEADQUARTERS

(Bin Liner replaces the receiver at her end after talking with Drinking Fountain. She is with Mel.)

MEL: What's happening?

BIN LINER: They're making all speed here.

MEL: What!?!

BIN LINER: Pex has been a scaredy cat. They'll be here in no time.

THE DOCTOR: I must tell the Doctor.

(Mel runs for the door but Bin Liner stops her before she steps on the tripwires.)

BIN LINER: Danger! Tripwires. This way.

(Bin Liner leads Mel out through the "unseen outway".)

25. INT. THE STREET

(The Doctor is with the Deputy Chief Caretaker and f*re Escape outside the Kang Headquarters. He is adjusting the door control.)

THE DOCTOR: That should do it.

(The Deputy Chief Caretaker notices Kroagnon, Pex and the two Cleaners appear at the other end of the street.)

DEPUTY CHIEF CARETAKER: Doctor! And we're not ready for him.

THE DOCTOR: Oh, Pex. Move back, quickly.

f*re ESCAPE: Oh, but Doctor, he'll make you unalive.

(Mel and Bin Liner appear on the street, having exited from the escape route.)

THE DOCTOR: There's only one way this might work, and for that I need to be on my own.

MEL: Come on.

(Mel, Bin Liner, f*re Escape and the Deputy all pull back to the other end of the Street, away from the Doctor. Kroagnon appears before the Doctor whilst Pex stand a little way behind him.)

KROAGNON: Well!?!

THE DOCTOR: Well, now, Kroagnon. How nice of you to drop in. I'm so glad. I wanted to have a word with you about the shoddy design of this building. I mean, take this door for instance, look at it.

KROAGNON: There was nothing wrong with it when I built it, unless humanoid creatures have damaged it.

THE DOCTOR: Well, speaking as an expert, I'm prepared to tell the universe you couldn't design a simple doorknob. I mean, look.

(Kroagnon growl as the Doctor points to the door. Kroagnon goes to look at it and the Doctor opens the door and attempts to push him inside. Kroagnon spins around and pushes the Doctor to his side. The others look on horrified. Pex makes to run away but the Cleaners stand in his way. He runs away in the other direction past the Doctor, who makes another attempt to push Kroagnon into the explosives-laden Kang Headquarters.)

THE DOCTOR: Pex!! Please!!

(Pex runs into Mel who looks at him disappointed. He remembers his Kang bracelet and goes back to help the Doctor who is being pushed repeatedly against the wall by Kroagnon. Pex pushes the Doctor aside and shoves the stick of expl*sive that Bin Liner gave him earlier into Kroagnon's hand. With one great leap he manages to push Kroagnon off his feet and through the door into the Kang Headquarters. Instantly the darkened interior explodes, debris flying everywhere.)

26. INT. THE SQUARE

(All the residents of Paradise Towers are gathered together to mourn and honour Pex. The Kangs stand around their memorial made from pieces of junk. The Rezzies and the Caretakers stand back looking on. Also present are the Doctor and Mel.)

BIN LINER: Hail Pex. Hail the unalive who gave his life for the Towers. In life he was not a Kang but in death he was brave and bold as a Kang should be.

(The Kangs, Red and Blue, stand as one and start to encircle the memorial.)

KANGS: Hail Pex. Hail the unalive. Hail Pex. Hail the Unalive.

(Mel and the Doctor look on.)

MEL: Poor Pex.

THE DOCTOR: Indeed, poor Pex. But look, Mel, they're all here. The Caretakers, the Rezzies, the Kangs. This would never have happened before. Perhaps now they'll all start working together.

MEL: Yes.

(f*re Escape, Bin Liner and Drinking Fountain move over to join the Doctor and Mel.)

THE DOCTOR: Ah, f*re Escape. Now, have you managed to remove the Kang wallscrawls from the TARDIS as you promised?

f*re ESCAPE: Build High for Happiness, Doctor.

(She passes the Doctor his umbrella with a sheepish grin.)

THE DOCTOR: Oh, thank you very much.

DRINKING FOUNTAIN: We're sorry you must go, Doctor and Mel. We've made you an honorary Kang, Doctor.

THE DOCTOR: Oh, a Blue Kang or a Red Kang?

(She passes a blue scarf over to the Doctor and f*re Escape shows him that it is red on the other side.)

f*re ESCAPE: Both.

THE DOCTOR: Ah, well I'll be honoured to wear it.

(He doffs his hat to them as they move off to join the procession.)

THE DOCTOR: And all my best wishes to the future of Paradise Towers.

(The Doctor and Mel wave goodbye to the others standing present and move over to the other side of the square where the TARDIS in standing waiting to depart. Mel unlocks the door. The Doctor doffs his hat to the same piece of metal rubbish that he said hello to when they arrived.)

THE DOCTOR: Goodbye.
