0:00:02 > 0:00:0413, Bannerman Road is where Sarah Jane Smith lives,
0:00:04 > 0:00:08and it's home to things way beyond your imagination.
0:00:08 > 0:00:12There's an extra-terrestrial super-computer in the wall,
0:00:12 > 0:00:14a genetically engineered boy genius in the attic,
0:00:14 > 0:00:17a schoolgirl investigator across the road
0:00:17 > 0:00:21and a whole universe of adventure right here on the doorstep.
0:00:25 > 0:00:26Ready?
0:00:26 > 0:00:28Always.
0:00:30 > 0:00:34We are Blathereen.
0:00:34 > 0:00:36I think it's a brilliant idea, a dinner party.
0:00:36 > 0:00:40This little plant could save millions of lives.
0:00:40 > 0:00:43Will you be our ambassador?
0:00:44 > 0:00:48Our Rakweed will change your planet for ever.
0:00:48 > 0:00:50How's the pot plant? Savaged anyone in the night?
0:00:50 > 0:00:52'The Rakweed is not harmless.'
0:00:52 > 0:00:56I can see that. There's a great big flower sticking out of it now.
0:00:56 > 0:00:57Mum, I'm so tired.
0:00:59 > 0:01:01What's this?
0:01:01 > 0:01:03'The plant appears to have mutated.'
0:01:03 > 0:01:06'It will send its victims into a deep, deep coma
0:01:06 > 0:01:09'from which they will never return.'
0:01:09 > 0:01:12Mr Smith, I need you.
0:01:12 > 0:01:13Mr Smith, please, help us!
0:01:29 > 0:01:31'Launching venting system.'
0:01:32 > 0:01:34'Maximum extraction.'
0:01:50 > 0:01:52Mr Smith, you are amazing!
0:01:52 > 0:01:55'Every computer has a cooling mechanism,
0:01:55 > 0:01:58'though applying it at full power has severely depleted
0:01:58 > 0:01:59'my energy banks.'
0:01:59 > 0:02:02What do I do with this thing?
0:02:10 > 0:02:13Luke, can you hear me? It's Mum.
0:02:13 > 0:02:15Yeah.
0:02:15 > 0:02:17I'm...I'm fine.
0:02:20 > 0:02:22Oh, Luke.
0:02:22 > 0:02:24What's it done to him?
0:02:24 > 0:02:26'The Rakweed spores not only re-seed the plant.
0:02:26 > 0:02:29'They are also its weapon against anything, or anyone,
0:02:29 > 0:02:33- standing in its path.'- Surely Luke's much stronger than a normal human?
0:02:33 > 0:02:37'He is, and maybe able to resist the effects for longer.
0:02:37 > 0:02:41'However, he inhaled the spores directly into his lungs.'
0:02:41 > 0:02:43Oh, Luke, I am so sorry.
0:02:45 > 0:02:50Do not write on the question sheet.
0:02:50 > 0:02:53Use the paper provided for your answers.
0:02:53 > 0:02:55Here you go, K9. Questions!
0:02:55 > 0:02:59Just relay your answers into this.
0:02:59 > 0:03:01'Relaying answers is unethical.'
0:03:01 > 0:03:03Shh! You said a test was
0:03:03 > 0:03:07"one human demonstrating intellectual superiority over others".
0:03:07 > 0:03:10I have brought a supercomputer into school.
0:03:10 > 0:03:12That's pretty smart, wouldn't you say?
0:03:15 > 0:03:18'Logic irrefutable.'
0:03:18 > 0:03:21Good dog. Now keep it short and to the point.
0:03:26 > 0:03:29You're actually going through with this, aren't you?
0:03:29 > 0:03:31Cheating at a test.
0:03:31 > 0:03:32No morals at all.
0:03:32 > 0:03:34And that's why you love me.
0:03:34 > 0:03:37Mmm, dream on, Clyde, dream on.
0:03:38 > 0:03:40'First question processed.'
0:03:40 > 0:03:43'Monitoring Luke's condition.
0:03:43 > 0:03:48'The poison has infected 63% of his cells, but time's running out.'
0:03:48 > 0:03:49You analysed the plant.
0:03:49 > 0:03:52You must have some idea how to fight it.
0:03:52 > 0:03:55'The Rakweed's genetic structure is adapting constantly.
0:03:55 > 0:03:58'It could take me days to create an antidote.
0:03:58 > 0:03:59'Even then it might not work.
0:03:59 > 0:04:01'We have half an hour at the most.'
0:04:01 > 0:04:05There's got to be a way. We must be able to help. He's only 15.
0:04:05 > 0:04:09'I'm receiving a local news report of a similar case to Luke's.'
0:04:09 > 0:04:11Put it up, Mr Smith.
0:04:11 > 0:04:13'This morning a number of people have
0:04:13 > 0:04:16'been admitted to Park Vale Hospital after collapsing at home or at work.
0:04:16 > 0:04:20'Doctors are unsure what has caused the unusual marks on their bodies,
0:04:20 > 0:04:24'although it has been suggested they may indicate a rare tropical disease.
0:04:24 > 0:04:27'This looks like it might be another case arriving now.
0:04:27 > 0:04:29- 'Excuse me, Doctor...- Stay back.
0:04:29 > 0:04:32'Excuse me, Doctor. Cameron Marsh, BBC News.
0:04:32 > 0:04:35'Any comment for BBC News, sir?
0:04:35 > 0:04:37'Any comment for BBC News, Doctor?'
0:04:40 > 0:04:42How quickly can it spread?
0:04:42 > 0:04:46'At its current rate of propagation, the Rakweed will have seeded
0:04:46 > 0:04:48'the whole of London within a few hours,
0:04:48 > 0:04:51'and in approximately three days
0:04:51 > 0:04:54'the plant could easily have consumed the entire planet.'
0:05:14 > 0:05:16Luke?
0:05:16 > 0:05:18Can you hear me?
0:05:18 > 0:05:21Yes, Mum, I can hear you...
0:05:21 > 0:05:24I'm leaving you with Mr Smith. He'll take care of you.
0:05:24 > 0:05:27'Where are you going, Sarah Jane?'
0:05:27 > 0:05:30If you can't give me an antidote, then there's no choice.
0:05:30 > 0:05:33The Blathereen started this and they're going to stop it.
0:05:33 > 0:05:36'But they'll be halfway across the galaxy by now.'
0:05:36 > 0:05:41You think? No, I bet they want to stick around, see their plan unfold.
0:05:41 > 0:05:43Scan for their ship, Mr Smith.
0:05:43 > 0:05:46'Their ship is shielded. Remember, I did not detect its approach.'
0:05:46 > 0:05:50'Without their teleport coordinates it cannot be located.'
0:05:50 > 0:05:52Lucky I made a note last night.
0:05:58 > 0:05:59What's that?
0:05:59 > 0:06:02BUZZING
0:06:03 > 0:06:05That was weird.
0:06:05 > 0:06:08What don't you understand about "absolute quiet", Clyde?
0:06:08 > 0:06:11- But, Miss...- If you recall, this is a test and that means...
0:06:11 > 0:06:14- 'Master Clyde?' - Are you hiding something?
0:06:17 > 0:06:21What on earth is that thing?
0:06:21 > 0:06:23Who's making that stupid noise?
0:06:23 > 0:06:25BUZZING
0:06:25 > 0:06:29Everyone, quiet.
0:06:29 > 0:06:33'Master Clyde, detecting alien plant DNA which has entered this room.'
0:06:37 > 0:06:39Is that Rakweed?
0:06:40 > 0:06:42- It's flowering. - What's it doing here?
0:06:42 > 0:06:45Will everyone please be quiet!
0:06:45 > 0:06:48Miss, that plant, I think it could be dangerous.
0:06:48 > 0:06:50- What plant?- Over there.
0:06:58 > 0:06:59Miss!
0:07:03 > 0:07:04SCREAMING
0:07:07 > 0:07:10Everyone get out of here right now!
0:07:12 > 0:07:14She's passed out.
0:07:17 > 0:07:20You're going to be all right.
0:07:20 > 0:07:23Nobody's taking you away from me.
0:07:28 > 0:07:31'Teleport trajectory indicates the Blathereen have left
0:07:31 > 0:07:33'Earth's immediate vicinity.'
0:07:38 > 0:07:42No, no, wait a moment. That beam's not heading away from Earth.
0:07:42 > 0:07:47- It's heading towards a satellite. - 'And being relayed back to Earth.'
0:07:47 > 0:07:48Antarctica.
0:07:52 > 0:07:53Ha-ha-ha-ha-ha.
0:07:53 > 0:07:58SLURPING AND GOBBLING
0:08:00 > 0:08:03You have to feel sorry for her.
0:08:03 > 0:08:08Why? She took the Rakweed because she wanted the glory.
0:08:08 > 0:08:10Same reason they always do.
0:08:10 > 0:08:13Get their ugly faces in the paper.
0:08:13 > 0:08:18I expected a little more resistance from the famous Sarah Jane Smith.
0:08:18 > 0:08:21She was a pushover! Ha ha ha ha!
0:08:21 > 0:08:25It's thanks to her that very soon their entire planet
0:08:25 > 0:08:28will be nothing but Rakweed.
0:08:30 > 0:08:34And then...let the harvest begin!
0:08:36 > 0:08:39BURPS
0:08:39 > 0:08:40LAUGHTER
0:08:46 > 0:08:48At least she's still breathing.
0:08:48 > 0:08:51We couldn't have helped her. It would have got us, too.
0:08:51 > 0:08:53I knew those Blathereen were trouble.
0:08:53 > 0:08:55We've got to stop this. Come on.
0:09:01 > 0:09:05Mr Smith, can you remotely activate the Blathereen teleport,
0:09:05 > 0:09:06get me to their ship?
0:09:06 > 0:09:10'I'd only have enough energy left for a one-way trip.'
0:09:10 > 0:09:11I'll take my chances.
0:09:11 > 0:09:14I'm not going to stand here and watch Luke die.
0:09:14 > 0:09:17'Who will save the world if something happens to you?'
0:09:20 > 0:09:24This time it's about Luke.
0:09:24 > 0:09:27'Rakweed now spreading throughout London.'
0:09:27 > 0:09:31LAUGHTER
0:09:39 > 0:09:41This is loaded with vinegar.
0:09:41 > 0:09:46You're going to do exactly as I say or I'll blast you to oblivion.
0:09:50 > 0:09:53She's alive. It's just knocking everyone out.
0:09:53 > 0:09:56How did the Rakweed get from Sarah Jane's house to here?
0:09:56 > 0:09:59You saw those seed things. It must be spreading itself.
0:09:59 > 0:10:01It's obviously not a good idea to breathe them in.
0:10:01 > 0:10:04Maybe that's what made Luke ill this morning.
0:10:09 > 0:10:11MOBILE RINGS
0:10:20 > 0:10:22- Rani?- 'Luke,'
0:10:22 > 0:10:25the Rakweed, it got you, didn't it? Are you OK?
0:10:25 > 0:10:28Yeah, I'm all right.
0:10:28 > 0:10:29You sound terrible.
0:10:29 > 0:10:32Where's Sarah Jane? Is she looking after you?
0:10:32 > 0:10:36She's gone...find Blathereen.
0:10:38 > 0:10:40'Luke?'
0:10:42 > 0:10:44Luke?
0:10:44 > 0:10:46He's ill. Really ill.
0:10:46 > 0:10:49And Sarah Jane's with the Blathereen. No idea where.
0:10:49 > 0:10:52Then we've got to sort this by ourselves, just the two of us.
0:10:52 > 0:10:55Correction, Master Clyde.
0:10:55 > 0:10:56Three of us.
0:10:56 > 0:10:59And you called me insane for bringing K9 to school.
0:10:59 > 0:11:01Come on. We've got to get to Luke.
0:11:08 > 0:11:09My son is dying
0:11:09 > 0:11:12and I'm not going to let you or anyone take him away from me.
0:11:12 > 0:11:14So keep perfectly still.
0:11:14 > 0:11:15I am feeling trigger-happy.
0:11:15 > 0:11:18You're making a terrible mistake.
0:11:18 > 0:11:22We didn't do anything. We're innocent. Honestly we are.
0:11:23 > 0:11:26I don't believe you. Now, fix it!
0:11:26 > 0:11:29All right, we knew the Rakweed would spread,
0:11:29 > 0:11:33but we didn't realise the damage it would do. We're sorry.
0:11:33 > 0:11:37We will reverse the process. Leef?
0:11:37 > 0:11:41We have no choice, my dear.
0:11:41 > 0:11:44Entering computer code.
0:11:44 > 0:11:49Destroy all Rakweed.
0:11:49 > 0:11:51The Rakweed is being eliminated.
0:11:51 > 0:11:52It will take a few seconds.
0:11:53 > 0:11:56Confirm Rakweed density on Earth.
0:11:56 > 0:11:59'Rakweed fully eliminated.'
0:11:59 > 0:12:03Would you mind putting the weapon down, Sarah Jane?
0:12:03 > 0:12:08- It's Miss Smith to you. - Please, Miss Smith?
0:12:11 > 0:12:13Let go of me!
0:12:13 > 0:12:16Computer, return to normal view.
0:12:18 > 0:12:21Good try, Miss Smith, but not good enough.
0:12:21 > 0:12:24That's exactly the phrase the Slitheen used.
0:12:24 > 0:12:26Now, we were just having dinner.
0:12:26 > 0:12:29Why don't you join us?
0:12:29 > 0:12:31- No, thank you.- But we insist.
0:12:35 > 0:12:37Why bother with these?
0:12:37 > 0:12:39Just wanted to see if they work.
0:12:39 > 0:12:42That chair cost a fortune.
0:12:42 > 0:12:43Ha-ha-ha-ha!
0:12:52 > 0:12:54BUZZING
0:12:57 > 0:12:59What do we do?
0:13:02 > 0:13:04It's everywhere!
0:13:04 > 0:13:07Watch out!
0:13:07 > 0:13:09'Please, stand back.'
0:13:18 > 0:13:20K9, can you blast them, too?
0:13:20 > 0:13:23'Energy required too great.
0:13:23 > 0:13:25'This unit has insufficient power.'
0:13:25 > 0:13:26We're trapped.
0:13:26 > 0:13:28Come on! The canteen.
0:13:32 > 0:13:36This is much more civilised, isn't it?
0:13:36 > 0:13:41Sure you won't take a little Rakweed? It really is delicious.
0:13:41 > 0:13:45Now I understand why you're obsessed with it.
0:13:45 > 0:13:47- You're addicted to it.- We are not!
0:13:47 > 0:13:50We...we just love it, that's all.
0:13:50 > 0:13:53You'd understand if you tried some.
0:13:53 > 0:13:57And my son is dying just to fuel your addiction.
0:13:57 > 0:14:00Even we couldn't eat all that, and we wouldn't want to.
0:14:00 > 0:14:02An entire planet of Rakweed
0:14:02 > 0:14:06will be worth a fortune on the galactic market.
0:14:06 > 0:14:11Small as Earth is, it's still a useful plot of land.
0:14:11 > 0:14:15Billions of people killed, and all you see is a plot of land?
0:14:15 > 0:14:18We're simple farming folk, Miss Smith.
0:14:18 > 0:14:25But one day our farm will span the entire galaxy.
0:14:28 > 0:14:31SLURPING AND GOBBLING
0:14:36 > 0:14:39How far's this spread? Just the school grounds or further?
0:14:39 > 0:14:42If it got from Sarah Jane's to here, it's not looking good.
0:14:42 > 0:14:44- Then there'll be news reports?- Yeah.
0:14:44 > 0:14:46It's clear.
0:14:46 > 0:14:48'Master Clyde, Mistress Rani...'
0:14:50 > 0:14:51Hurry up!
0:14:56 > 0:14:58'Cases of the, as yet, unidentified infection
0:14:58 > 0:15:00'have increased to over 300,
0:15:00 > 0:15:03'and doctors warn there could be more in the coming days.
0:15:03 > 0:15:06'It all started in Ealing, but it's now spread as far
0:15:06 > 0:15:09'as Southall, Perivale, Acton and Chiswick.
0:15:09 > 0:15:12'Members of the public, especially those in West London,
0:15:12 > 0:15:15'are advised to act with extreme caution.'
0:15:15 > 0:15:18What would Sarah Jane do?
0:15:18 > 0:15:20She'd do what she always does - improvise.
0:15:20 > 0:15:22Come on.
0:15:23 > 0:15:27What a joy to see someone as smug
0:15:27 > 0:15:32as Sarah Jane Smith destroy the planet she fought so hard to save.
0:15:32 > 0:15:35Kill me by all means, but not the children.
0:15:35 > 0:15:38Don't you have any of your own?
0:15:38 > 0:15:40Oh, no. Nasty little things.
0:15:40 > 0:15:42Profit is our progeny.
0:15:42 > 0:15:46Isn't using the Earth for a fast buck more the Slitheen style?
0:15:46 > 0:15:50How dare you! We're nothing like the Slitheen.
0:15:50 > 0:15:52We're much, much worse.
0:15:52 > 0:15:57They lack our cunning, our vision, our good looks.
0:15:57 > 0:15:59Now, now, Leef.
0:15:59 > 0:16:02We must still show some tolerance towards our relatives.
0:16:02 > 0:16:05Your relatives?
0:16:05 > 0:16:08Didn't we say? We're double-barrelled, Miss Smith.
0:16:08 > 0:16:10We are the Slitheen-Blathereen,
0:16:10 > 0:16:16the descendants of an inter-clan marriage many generations ago.
0:16:16 > 0:16:18Why doesn't that surprise me?
0:16:18 > 0:16:20You're as bad as they are!
0:16:20 > 0:16:23For that remark, we won't kill you.
0:16:23 > 0:16:28We'll keep you alive to watch your beloved Earth die.
0:16:28 > 0:16:31And then we'll kill you. Ha-ha-ha!
0:16:37 > 0:16:40Right, that's the gym, art and canteen blocks.
0:16:40 > 0:16:44There's got to be one exit that isn't blocked by Rakweed.
0:16:47 > 0:16:48What about a window?
0:16:51 > 0:16:52It's locked.
0:16:55 > 0:16:58- Give me a shove up. - Oh, all the glamorous jobs.
0:17:00 > 0:17:03Oh, even I could get through that.
0:17:04 > 0:17:06'Warning. Danger.'
0:17:09 > 0:17:10- Get back!- Clyde, don't!
0:17:12 > 0:17:14SCHOOL BELL JANGLES
0:17:16 > 0:17:18What?!
0:17:20 > 0:17:22How did that just happen?
0:17:22 > 0:17:24End of period bell. Must have been.
0:17:26 > 0:17:27Saved by the bell.
0:17:29 > 0:17:32That's what I like to see.
0:17:32 > 0:17:35My wonderful little plant spreading.
0:17:42 > 0:17:43You know, it was my husband
0:17:43 > 0:17:47who engineered this wonderful new strain of Rakweed?
0:17:47 > 0:17:51Genetically modified to re-seed at an incredible rate.
0:17:51 > 0:17:57The Rakweed's song will be filling the air. How sweet it must sound.
0:17:57 > 0:17:59You mean that awful noise?!
0:17:59 > 0:18:00Hardly call that a song.
0:18:00 > 0:18:07It's a living thing. Communication is the mainstay of all life.
0:18:07 > 0:18:10Communication?
0:18:10 > 0:18:12That's interesting.
0:18:12 > 0:18:16Without that, how can the Rakweed unite and colonise an entire planet?
0:18:16 > 0:18:20'Rakweed now at 93%.'
0:18:20 > 0:18:21Miss Smith?
0:18:24 > 0:18:27She can't just have vanished!
0:18:32 > 0:18:34Lost something?
0:18:34 > 0:18:36Leave that alone!
0:18:39 > 0:18:41Get after her, you idiot!
0:18:41 > 0:18:43Activate the teleport.
0:18:46 > 0:18:48She's broken it, stupid woman!
0:18:48 > 0:18:54Well, un-break it! We're paying Miss Smith a visit,
0:18:54 > 0:18:58and this time it'll be us having her for dinner!
0:18:59 > 0:19:01Luke?
0:19:06 > 0:19:08We need you to set the bell off again,
0:19:08 > 0:19:12- but much, much louder this time. - K9, can you boost the volume?
0:19:12 > 0:19:14'Easily accomplished.'
0:19:16 > 0:19:19'Frequency adjusted. Activating.'
0:19:20 > 0:19:23SCREECHING
0:19:23 > 0:19:25It's working.
0:19:30 > 0:19:31Way to go, K9! You did it!
0:19:31 > 0:19:33Can you turn it off now?
0:19:40 > 0:19:44- It's still alive outside. - We're never going to defeat it.
0:19:46 > 0:19:48Can you link me to Mr Smith?
0:19:48 > 0:19:52'If necessary. However, contact with that computer interferes
0:19:52 > 0:19:54'with this unit's synaptic circuits.'
0:19:54 > 0:19:56You mean he gets on your nerves?
0:19:56 > 0:20:00- 'Affirmative.'- Those two have really got to work through their issues.
0:20:05 > 0:20:07Clyde! Are you OK?
0:20:07 > 0:20:08Yeah, we're fine.
0:20:08 > 0:20:12And we think we've found a way to kill the Rakweed - the school bell.
0:20:12 > 0:20:14Brilliant! You're both brilliant!
0:20:14 > 0:20:16'It seems to work, but we're not sure why.'
0:20:16 > 0:20:19'It's because the Rakweed is connected by that'
0:20:19 > 0:20:20terrible wailing sound.
0:20:20 > 0:20:23It's how the plant stays alive, communicates.
0:20:23 > 0:20:24'The bell must break that link.'
0:20:24 > 0:20:28So we should blast the sound of the bell across the entire city?
0:20:28 > 0:20:30- Or something similar. - 'Good thinking, Rani.
0:20:30 > 0:20:33'Replicate it and we're winning. Mr Smith?'
0:20:33 > 0:20:37'I can do that, but I would need to know the exact frequency.'
0:20:37 > 0:20:38'K9 can tell you.'
0:20:38 > 0:20:41K9? What's he doing there?
0:20:41 > 0:20:43I'll explain later.
0:20:43 > 0:20:45K9, give Mr Smith the bell's frequency.
0:20:45 > 0:20:47'1421.09 hertz.'
0:20:47 > 0:20:51'I am now linking to all electrical devices in the area invaded
0:20:51 > 0:20:54'by the Rakweed and retuning them to replicate the bell's frequency.
0:20:54 > 0:20:57- 'Prepare yourself, Sarah Jane.' - Cover your ears.
0:20:57 > 0:21:00This is going to be really, really loud.
0:21:01 > 0:21:04BELLS RING AND SIRENS WAIL
0:21:21 > 0:21:24That's enough for now.
0:21:37 > 0:21:39It's over!
0:21:39 > 0:21:41Yes!
0:21:41 > 0:21:44Go, Clydey. Go, Rani. Go, Sarah Jane!
0:21:44 > 0:21:47- Yeah, never mind all that. Let's get out of here.- Yeah.
0:21:47 > 0:21:52- Mum... You're back.- Luke, thank goodness you're all right!
0:21:52 > 0:21:55What happened?
0:21:55 > 0:21:57Clyde and Rani, they're brilliant.
0:21:57 > 0:21:59And so are you.
0:21:59 > 0:22:03I was more frightened than I've ever been in my life.
0:22:03 > 0:22:06I nearly lost the most important thing in the Universe.
0:22:06 > 0:22:09You. Oh, Luke.
0:22:16 > 0:22:18It's gone!
0:22:18 > 0:22:21No, it's all gone!
0:22:21 > 0:22:24Our Rakweed crop, dead!
0:22:25 > 0:22:29Miss Smith is going to regret this.
0:22:29 > 0:22:32As soon as I've adjusted the focusing crystal, we're away.
0:22:32 > 0:22:37And then she will pay...in blood!
0:22:38 > 0:22:40That noise, Mr Smith.
0:22:40 > 0:22:45If I needed you to produce it again but just in the attic, could you?
0:22:45 > 0:22:48- 'Yes, but for what purpose?' - Sarah Jane!
0:22:48 > 0:22:50- Are you OK?- Yeah, I'm fine now.
0:22:50 > 0:22:53Destroying the Rakweed seems to reverse its effects.
0:22:53 > 0:22:57And you two are absolute stars. What a team you make!
0:22:57 > 0:23:00Just put it down to pure genius.
0:23:00 > 0:23:01'Mistress.'
0:23:01 > 0:23:03K9, what happened to you?
0:23:03 > 0:23:07- Rani and I took him for...walkies. - Don't drag me into this.
0:23:07 > 0:23:11'Negative. Master Clyde took me to school to assist with his tests.'
0:23:11 > 0:23:12He did, did he?
0:23:12 > 0:23:17Clyde, you don't need to cheat. Have faith in your own abilities.
0:23:18 > 0:23:21We meet again, Miss Smith!
0:23:21 > 0:23:24Oh, why don't you just go home?
0:23:24 > 0:23:27This is your final warning.
0:23:27 > 0:23:32The Slitheen-Blathereen do not take kindly to ultimatums!
0:23:32 > 0:23:34Slitheen-Blathereen? I knew it!
0:23:34 > 0:23:36Then they're only half-bad.
0:23:36 > 0:23:40Rani's right. Why don't you forget your Slitheen side,
0:23:40 > 0:23:43give your Blathereen blood a chance?
0:23:43 > 0:23:45Not all your family can be crooked.
0:23:45 > 0:23:50The Blathereen are useless, soft-hearted do-gooders.
0:23:50 > 0:23:52Nothing but middle management.
0:23:52 > 0:23:54We prefer the view from the top.
0:23:54 > 0:23:57I didn't want to have to do this, but you leave me no choice.
0:23:57 > 0:24:02I've been dying to say this for ages. Let the hunt begin!
0:24:02 > 0:24:04Hit it, Mr Smith!
0:24:04 > 0:24:06JANGLING BELLS
0:24:13 > 0:24:15Ha-ha-ha!
0:24:15 > 0:24:20It is our sense of smell that's highly developed, not our hearing.
0:24:23 > 0:24:26BURPING
0:24:26 > 0:24:28That's enough, Mr Smith!
0:24:28 > 0:24:31Aaagh! Aaagh! Aaagh!
0:24:33 > 0:24:35What have you done to us?
0:24:35 > 0:24:36My stomach! It's...
0:24:36 > 0:24:40SQUELCHING
0:24:40 > 0:24:42Aaagh! Aaagh!
0:24:42 > 0:24:44I'm sorry.
0:24:44 > 0:24:46SQUELCHING AND RIPPING
0:25:14 > 0:25:16'Disintegration successful.'
0:25:16 > 0:25:17'You don't say(!)'
0:25:17 > 0:25:19Why does this always happen to me?
0:25:19 > 0:25:22Mum, you did it!
0:25:25 > 0:25:27They were going to kill us.
0:25:27 > 0:25:29I had to do it.
0:25:29 > 0:25:31What did you do?
0:25:31 > 0:25:36On their ship, all they did was stuff their faces with Rakweed.
0:25:36 > 0:25:39I knew their stomachs would still be full of it.
0:25:39 > 0:25:43'The destruction of the undigested Rakweed created methane gas.
0:25:43 > 0:25:45'It could not be contained.'
0:25:45 > 0:25:48So they farted themselves to death?
0:25:48 > 0:25:50'In a nutshell, Master Clyde.'
0:25:50 > 0:25:52But this isn't how it should end.
0:25:52 > 0:25:55There should've been another way.
0:25:55 > 0:25:57A better way.
0:25:58 > 0:26:01You're amazing, Sarah Jane.
0:26:05 > 0:26:10Which is more than can be said for people who cheat at tests.
0:26:10 > 0:26:15But who's ever gonna want to know about the life cycle of a plant?
0:26:15 > 0:26:17Ah-hem...
0:26:17 > 0:26:19Fair enough.
0:26:19 > 0:26:25Now, fetch yourself a mop in the kitchen and clean up this mess.
0:26:31 > 0:26:34'For once, I truly hoped we'd found a friend out there,
0:26:34 > 0:26:37'someone Earth could trust,
0:26:37 > 0:26:41'a way for us all to move forward, humans and aliens together.
0:26:41 > 0:26:44'I was wrong... This time.'
0:26:44 > 0:26:47One clean attic!
0:26:47 > 0:26:50'But it doesn't mean our next visitors will be the same.'
0:26:50 > 0:26:52You've cremated our picnic.
0:26:56 > 0:26:59'There are friends out there, too.
0:26:59 > 0:27:02'Friends who really will want to help us.
0:27:02 > 0:27:07'And as we all know, there's nothing more important than friendship.
0:27:09 > 0:27:15'And then, one day, with a little luck and a lot of hard work,
0:27:15 > 0:27:20'Earth could be a shining example to the entire Universe.'
