(There is a device next to Clyde.)
CLYDE: Sounds like a countdown.
(Then he vanishes.)

[Corridor]

(And replaces the Doctor. The Shansheen stop their attack in astonishment.)
CLYDE: But I was on a planet.
SARAH JANE: Never mind that. Run!

[Alien planet]

DOCTOR: Come on, come on.
(He jiggles the device.)

[Corridor]

SARAH JANE: Faster.
DOCTOR: Come along, Smith.

[Alien planet]

CLYDE: No, no, no! Don't slow down. Take me back.

[Corridor]

DOCTOR: In, in, in.
(Everyone runs into the dormitory.)
KARIM: I'm sorry, is there a problem?
(The Doctor enters the room.)
DOCTOR: Sorry, I was slamming it.

[Dormitory]

DOCTOR: Right. Now we need to lock it. Come on, use the sonic lipstick.
SARAH JANE: Haven't you got the screwdriver?
DOCTOR: They took it.
JO: They do sonic lipsticks now.
DOCTOR: We're running out of time. I need you, Sarah, and you, Jo.
JO: Need us for what?
(The Doctor takes their hands.) 
DOCTOR: Remember the old days when we'd go zooming off to faraway worlds?
(The three are replaced by Clyde.)
CLYDE: I'm getting spacesick.

[Alien planet]

DOCTOR: No, no, no, no. Let's get you working properly. Stop.
SARAH JANE: Where are we?
DOCTOR: The Wasteland of the Crimson Heart. Planet Earth's that way. Bit of a long walk. Sonic, please.
JO: It's so many years since I was on another planet.
SARAH JANE: Me too.

[Outside the dormitory]

KARIM: I'm sorry, but can I help?

[Dormitory]

KARIM [OC]: Is there something wrong?
SANTIAGO: But she's on our side, isn't she?
RANI: Think about it. The Doctor's been avoiding her, but why? Because someone inside UNIT had to fake the DNA results. Colonel Karim. She's in league with the Shansheeth.

[Outside the dormitory]

KARIM: Not as daft as they look, for two batty old pensioners and a bunch of ASBO kids. How on Earth did they summon the Doctor?
SHANSHEETH: They have powers unforeseen.
KARIM: Right. First things first. We need to clear this place, seal it off and keep that lot trapped.

[Dormitory]

(Rani calls up a schematic of Unit Base Five on a screen.)
RANI: Do you see? We're slap-bang in the middle of the base. There's got to be a way of getting help.
(A klaxon sounds.)
SANTIAGO: What's happening?
RANI: Karim's sealed off the entire Funeral Wing. We're trapped.
(The Groske kicks off the ventilation shaft grill.)
GROSKE: Hurry. Follow me.

[Chapel]

SHANSHEETH: Dispense with the coffin. Prepare this room for the coalescence. Behold, the Memory Weave is ready.
(Mist clears to reveal the Tardis.)
SHANSHEETH: Soon it will be active. Deliver the women into our wings, and not even the Doctor will able to stop the crusade of the Shansheeth.

[Alien planet]

(The Doctor and Sarah Jane are working on the device.)
DOCTOR: There, and there.
SARAH JANE: Did it hurt? I mean, the regeneration. That last body of yours, was he okay in the end?
DOCTOR: It always hurts. And there.
SARAH JANE: So how did you end up in this place?
DOCTOR: The Shansheeth lured me. A mighty old battlefield, just begging to be explored. Because I'm travelling with Amy now. And Rory. They got married. I dropped them off at a honeymoon planet, which isn't what you'd think. It's not a planet for a honeymoon, it's a planet on a honeymoon. It married an asteroid. Then they nicked the Tardis. The Shansheeth, not Amy and er. Fortunately, I had all this wreckage to build a space swapping doo-dah thingummy wotsit.
JO: So, you've a married couple in the Tardis.
DOCTOR: Mister and Mrs Pond.
JO: I only left you because I got married. Did you think I was stupid?
DOCTOR: Why do you say that?
JO: I was a bit dumb. Still am, I suppose.
DOCTOR: Now what in the world would make you think that, ever, ever, ever?
JO: We'd been travelling down the Amazon for months, and we reached a village in Cristalino, and it was the only place in thousands of miles that had a telephone, so I called you. I just wanted to say hello. And they told me that you'd left, left UNIT, never came back. So I waited and waited, because you said you'd see me again. You did, I asked you and you said yes. You promised. So I thought, one day, I'd hear that sound, Deep in the jungle, I'd hear that funny wheezing noise, and a big blue box right in the middle of the rainforest. You see, he wouldn't just leave. Not forever. Not me. I've waited my whole silly life.
DOCTOR: But you're an idiot.
JO: Well, there we have it.
DOCTOR: No, but don't you see? How could I ever find you? You've spent the past forty years living in huts, climbing up trees, tearing down barricades. You've done everything from flying kites on Kilimanjaro to sailing down the Yangtze in a tea chest. Not even the Tardis could pin you down.
JO: Hold on. I did sail down the Yangtze in a tea chest. How did you know?
DOCTOR: And that family. All seven kids, twelve grandchildren, thirteenth on his way. He's dyslexic but that'll be fine. Great swimmer.
JO: So you've been watching me all this time?
DOCTOR: No. Because you're right, I don't look back. I can't. But the last time I was dying, I looked back on all of you. Every single one. And I was so proud.
JO: It really is you, isn't it?
DOCTOR: Hello.
SARAH JANE: Sorry, but we've got that lot back at home with the Shansheeth.
DOCTOR: Yes, yes. And I still need you, Jo. Now, that bag of yours, I can smell blackcurrant. Is it buchu oil?
JO: Hand-picked in Mozambique.
DOCTOR: Oh, perfect. These circuits need connectivity. Wonderful. Little tiddly drop. That's it. What a team.

[Groske hideaway]

GROSKE: Hurry, hurry, hurry. Come on.
CLYDE: Hey, nice. You've got a little den. What's all the hurry for?
GROSKE: Pizza go cold.
CLYDE: What? I thought you had a plan.
GROSKE: Shansheeth too scary. We hide.
CLYDE: No, we've got to do something.
RANI: Yeah, but hiding's not bad, because we've got to keep you safe, Clyde. Whatever the Doctor's doing, he needs you for that body switcheroo.
CLYDE: Oh great, great. Stuck in Groskeville.
GROSKE: Pizza good.
SANTIAGO: I can't believe you get to do this all the time. Like aliens and chases and stuff.
CLYDE: You can talk, Santiago. You're off to Paraguay and Mount Everest.
SANTIAGO: Dude, you just zapped into another planet.
CLYDE: Yeah, that was pretty cool.
RANI: We've been to parallel times, dream dimensions, limbo. And then we go home for tea.
CLYDE: We see all this, then my mum's like, What did you do today? I'm like, not much.
RANI: Went to the library.
CLYDE: Played a bit of footie.
RANI: Stayed behind after Drama Club.
CLYDE: And I fought off a platoon of Judoon in my spare time.
SANTIAGO: I've not seen my mum for six months now.
RANI: How come?
SANTIAGO: She's in Japan, organising a rally. I mean, that's great, you know. It's really good work.
CLYDE: Yeah, of course it is.
SANTIAGO: Before that, she was in Africa, finding shell flower plants. My father's with the Gay Dads Organisation, hiking across Antarctica. We haven't all been together since about February?
RANI: When are you going to see them next?
SANTIAGO: Soon. I don't know. Soon though.
(A shutter falls across the ventilation access.)
CLYDE: What's that? What's happening?.
GROSKE: Trapped.

[Chapel]

(With a handy computer link to the base systems.)
KARIM: Excellent. We've got the Brady Bunch exactly where we need them. Now to apply a little heat.
COMPUTER: Internal vents to maximum.

[Groske hideaway]

GROSKE: Heating. Hot, hot, hot.
RANI: They're trying to boil us.

[Chapel]

KARIM: And increasing.
SHANSHEETH: The children are irrelevant.
KARIM: Not to the Doctor, they're not. Wherever he is, he'll be planning revenge. We need to divert him.

[Groske hideaway]

CLYDE: It won't budge. Come on, Groske, there's got to be a way out.
GROSKE: No. We die like rotisserie.
RANI: You can, but I'm not. Sarah Jane! Anyone!
CLYDE: Oi! Where are you?

[Alien planet]

DOCTOR: There. That should work. Intergalactic molecular streaming, with just a hint of blackcurrant.
SARAH JANE: But what'll happen to Clyde?
DOCTOR: No, no, no, I've fixed it. All I needed was you two. Oil and sonic. Now we can go back and Clyde can stay where he is. Hold tight.

[Corridor]

CLYDE [OC]: Get us out of here. Doctor!
DOCTOR: Then again, maybe leaving Clyde in the same place wasn't such a good idea.
SARAH JANE: Look out, stand back.
(Sarah Jane sonicks off the grill.)
DOCTOR: Ah! Ventilation shafts. That takes me back. Or even forwards.

[Shaft]

CLYDE [OC]: Hurry up. We're getting boiled alive.
DOCTOR: Hold on. We're coming.
JO: Don't worry, Santiago, I'm here. You go first. You've got the sonic lipstick.
(Jo turns to see Sarah Jane is being held by a Shansheeth. Then a second one grabs her.)
SARAH JANE: Doctor!
DOCTOR: Jo? Sarah?
CLYDE [OC]: They're roasting us.

[Groske hideaway]

RANI: Let us out!

[Shaft]

DOCTOR: Sarah. Argh!

[Chapel]

KARIM: Exactly as predicted. Given the choice between saving the world, or saving the children, the Doctor goes the wrong way.
(The Shansheeth bring Sarah Jane and Jo in.)
SARAH JANE: I didn't trust you, Colonel, from the moment I met you.
KARIM: Like I care. Frankly, I've never met anyone so staggeringly pious in all my life. Now then. The chamber's sealed off. The Doctor would need half a ton of dynamite to get through that.
JO: The Tardis. I never thought I'd see it again.
KARIM: That's what this is all about. The Tardis, and you. Place them in the Memory Weave.
(Jo and Sarah are attached to Shansheeth technology.)

[Shaft]

DOCTOR: And release.

[Groske hideaway]

CLYDE: Blimey. You really have changed faces, haven't you? I couldn't see you before, I was too busy swapping.
RANI: Oi, we're still cooking back here.
SANTIAGO: Where's my gran?
DOCTOR: Right, yes, sorry, she's in danger, so, we'd better er. Can't turn round.
CLYDE: You'll have to shuffle backwards.
DOCTOR: Oh, yes, okay. Thank you, Clyde.

[Shaft]

CLYDE: Even your eyes are different. It's weird, cos I thought the eyes would stay the same. Can you change colour or are you always white?
DOCTOR: I could be anything.
CLYDE: And is there a limit? How many times can you change?
DOCTOR: Five hundred and seven.
(5+0+7=12, everyone.)

[Chapel]

SARAH JANE: Hang on, then. Tell us, what exactly does a Memory Weave do?
JO: Because I warn you, darling, the memory's going at my age.
SHANSHEETH: You need remember only one thing.
SARAH JANE: And what's that?
SHANSHEETH: The Tardis key.
KARIM: The Weave takes the memory out of your head, and makes it real. This device can build a physical key out of your thoughts.
SHANSHEETH: And then, we will have access to the Tardis. The most miraculous machine in creation will be ours.
SARAH JANE: No.

[Dormitory]

(The hum of the Memory Weave can be heard.)
DOCTOR: They've started.

[Chapel]

JO: No, you can't. Ow!
(This is not a painless procedure.)
SHANSHEETH: We have seen so much of death. The Shansheeth have presided over infinite funerals. We see the pain and the suffering again and again and again. But with the Tardis, we can stop this. We can intervene to prevent the loss of life on a universal scale.
SARAH JANE: You're going to stop death?
SHANSHEETH: It is a noble quest. To halt the endless, endless weeping.
SARAH JANE: And change the whole of history. That's why creatures like you can't have time machines. Because you'll wreck the entire universe.
KARIM: What did I say? Pious.
SARAH JANE: Oh yeah? Well, I'd rather be pious than vile. What do you get out of this, Colonel?
KARIM: A bigger horizon, Miss Smith. The Shansheeth can take me to the stars, because there is nothing left for me here on Earth. Not any more. Accelerate the Weave.

[Outside the Chapel]

DOCTOR: They've sealed it off. Jo, Sarah, can you hear me?

[Chapel]

SARAH JANE: They want the key. They've got the Tardis, and a Memory Weave.
KARIM: Too late. Full activation.
SHANSHEETH: Concentrate. Think of the key.

[Outside the Chapel]

DOCTOR: Try to find a way in.
SANTIAGO: There's nothing. We need a bulldozer.
DOCTOR: I've got the original here. You can have it if you let them go.

[Chapel]

KARIM: You let the Doctor inside this room and he will destroy us. Keep going!
SHANSHEETH: Think of the Tardis.
(Memories come into Jo and Sarah's minds. The Three Doctors amongst others.)
SHANSHEETH: The key. Remember the key.
JO: Fight it, Sarah Jane. Try to think of something else.
SARAH JANE: I can't.
JO: Neither can I.

[Outside the Chapel]

(Clyde tries hitting the steel doors with a fire extinguisher.)
CLYDE: It's not shifting.

[Chapel]

SHANSHEETH: The memories coalesce. The key, it takes shape.
JO: Don't! Don't!
SARAH JANE: I can't stop.

[Outside the Chapel]

CLYDE: What do we do, Doctor? What do we do?
DOCTOR: Because the Shansheeth are making them remember.
CLYDE: I know.
DOCTOR: Then don't you see?
CLYDE: I don't see anything.
DOCTOR: We do the same. Opening comms. Sarah, Jo, can you hear me?

[Chapel]

SARAH JANE: The key, it's almost ready.

[Outside the Chapel]

DOCTOR: Listen to me, both of you. I want you to remember.

[Chapel]

JO: We are doing. That's the trouble.

[Outside the Chapel]

(The Groske goes to the control unit.)
DOCTOR: No, no, no, no. I want you to remember everything. Every single day with me. Every single second.

[Chapel]

KARIM: What's he doing?

[Outside the Chapel]

DOCTOR: Because your memories are more powerful than anything else on this planet. Just think of it. Remember it. But properly. Properly. Give the Memory Weave everything. Every planet, every face, every madman, every loss, every sunset, every scent, every terror, every joy, every Doctor. Every me.
SARAH JANE: I remember.
(Lots of flashes of past adventures, including the Brigadier, Zygons, Doctors.)
KARIM: No!
COMPUTER: Memory Weave overloading.
JO: I remember.
(Daleks, Drashig.)
KARIM: We need that key. What is happening?
(Aggedor, the Master, etc, etc.)
KARIM: What's happening?
COMPUTER: Initial target lost.
SHANSHEETH: The device is overloading. Too many memories. Too many.
KARIM: Reverse it. Bring that key back.

[Outside the Chapel]

DOCTOR: Come on, all of you. Tell them, tell them.
CLYDE: Think of us, Sarah Jane. Remember Maria and her dad, and all the stuff we did, like the Gorgon.
RANI: And the clowns, and the zodiac. And the Mona Lisa.

[Chapel]

SARAH JANE: All of it. All of it.
SANTIAGO [OC] Just think, Gran. All the countries you've been to.
JO: Every country in the world.
COMPUTER: Weave starting to self-destruct.
(Sarah Jane gets free.)
SARAH JANE: It's blown a circuit.
JO: I can't get out.
SARAH JANE: I've got you.

[Outside the Chapel]

DOCTOR: Now we're in trouble. The Weave's going to blow up and we can't get them out.
RANI: What?
DOCTOR: Can't escape.

[Chapel]

SHANSHEETH: I need the key.
COMPUTER: Weave now entering detonation phase.
(Things are going bang and starting fires.)
KARIM: I can't unseal the doors. The power line is gone. Argh!
(Sarah Jane tries to use her sonic lipstick on the door.)
SARAH JANE: We've drained it. Doctor? Doctor, I can't get out.

[Outside the Chapel]

DOCTOR: I can't open it.

[Chapel]

SARAH JANE: No sonic screwdriver.

[Outside the Chapel]

DOCTOR: It's inside the Tardis.

[Chapel]

SARAH JANE: And we can't get in, because guess what? We stopped ourselves getting the key. Oh, that was clever.
JO: I just want to say, I'm so glad I saw you again. I waited all this time, and it was worth it. Every second. Funny thing is though, your funeral turns out to be ours instead.

[Outside the Chapel]

DOCTOR: My funeral?

[Chapel]

SARAH JANE: Doctor, all of you, you'll look after Luke for me, please.

[Outside the Chapel]

DOCTOR: No, no, no, no, but listen. My funeral. Don't you see? It's my funeral.

[Chapel]

JO + SARAH JANE: With a lead-lined coffin!
(They prise up the lid and climb in.)

[Outside the Chapel]

DOCTOR: How much time have they got?
GROSKE: Big bang, ten seconds.
DOCTOR: Come on.
GROSKE: Ten

[Chapel]

GROSKE [OC]: Nine
COMPUTER: Total destruction imminent.
(The Shansheeth is hammering on the Tardis door.)

[Corridor]

(The Doctor and the children take cover.)
GROSKE: Seven, six.
SANTIAGO: Hurry up, Gran.
GROSKE: Five, four, three, two
(KaBOOM! The fireball blows the doors off.)
DOCTOR: What do you mean, the Mona Lisa?

[Chapel]

(Anything organic has been incinerated.)
GROSKE: Smells like roast chicken.
DOCTOR: Now then. Smith and Jones.
(The Doctor opens the coffin lid.)
DOCTOR: The coffin was the trap. The coffin was the solution. That's so neat, I could write a thesis. Come on then, you two. Out you get.

[Attic]

MR SMITH: Attention. Temporal flux escalating in this vicinity. The Tardis has landed.
(And parked herself just under the skylight.)
CLYDE: Whoa. It's Bannerman Road. It's like everything moved. I'm never getting used to that.
RANI: Mister Smith, you're in big trouble. Those Shansheeth were bad.
MR SMITH: It transpires that you encountered a rogue element, and the Wide Wing of the High Shansheeth Nest sends apologies.
SANTIAGO: No way. On top of everything else, you've got a talking computer? That is it. I'm giving up.

[Tardis]

JO: Still the same old Tardis. It doesn't matter what's changed, it still smells the same. No. I've got to say goodbye, or else I'd stay with you forever. Besides, I probably couldn't keep up any more. Get you into trouble with the Time Lords.
DOCTOR: Hmm. Yeah, I'd probably better go. You know me, stuff to do.
SARAH JANE: It's daft, though, because we were both saying, we had this theory that if you ever died, we'd feel it, somehow we'd just know. But that's just silly, isn't it?
DOCTOR: I don't know. Maybe not. Because between you and me, if that day ever comes. I think the whole universe might just shiver.
(Then he gives a start, and they all laugh.)

[Attic]

SANTIAGO: But you should see Japan. It's amazing. It's like eighty percent forest. It goes on as far as the eye can see. It's endless.
(Jo and Sarah come out of the Tardis, and it dematerialises.)

[Outside Sarah Jane's home]

SANTIAGO: It's exactly like you said. You live over there, you're
CLYDE: Just down there, on the left.
SANTIAGO: You save the world, then you just come home.
RANI: The thing is, maybe you could do with a bit of that. See, we're fighting the Slitheen and the Trickster and you're fighting oil barons and factories, but at the end of the day, who's waiting for you?
CLYDE: I think you should start another protest. except this time, at your mum and dad. Or they might find that relations with Santiago get decidedly Chile. Let's pretend I never said that.
RANI: That was horrific.
CLYDE: I'm ashamed of myself.
SANTIAGO: You're right, though. Yeah, I think it's time we made some changes.
JO: Oh, you. You're so beautiful and so gorgeous. (to Rani) And you, you are so willowy. Yes, you are. Do you know, you are sensational. (to Santiago) And you, you are so handsome. And we're so late. Come on. We're off to Norway by hovercraft. Should be fun.
SANTIAGO: Easier said than done.
JO: Bye, everyone. Oh, Sarah Jane, find yourself a fellow. Hang on, wait a minute, glasses. Where did I leave my glasses? What? Oh, Lord. Head, naturally. Bye. See you later.
SANTIAGO: See you, guys.
(Jo and Santiago get into a taxi.)
RANI: Do you think there's lots of Jo Grants out there? You know, like the Doctor's old companions?
SARAH JANE: I do a little search sometimes.
CLYDE: What do you google, Tardis?
SARAH JANE: It works. No, I can't be sure, but there's a woman called Tegan in Australia, fighting for Aboriginal rights. There's a Ben and Polly, in India, running an orphanage there. There was Harry. Oh, I loved Harry. He was a doctor. He did such good work with vaccines. He saved thousands of lives. And there's a Dorothy something. She runs that company, A Charitable Earth. She's raised billions. And this couple in Cambridge, both professors. Ian and Barbara Chesterton. Rumour has it, they've never aged. Not since the sixties. I wonder.
CLYDE: That'll be us, one day.
RANI: Still out there, fighting.
SARAH JANE: Echoes of the Doctor, all over the world. With friends like us, he's never going to die, is he?
