Rose watched on as Donna flew the Tardis. She was almost laughing at how worried the Doctor looked at the sight. She was practically having to hold him back from just taking over. There were very few people he trusted to fly the Tardis, she and Jack amongst them. She, however, knew that the Tardis would never let Donna crash. And she looked so delighted flying on her own.

"I can't believe I'm doing this!" Donna said with her voice, almost squealing.

"No, neither can I," he replied. The TARDIS started shaking more than usual. "Oh! Whoa, careful!" he picked up the rubber mallet and bashed the console a bit, before lifting a lever. The mallet was immediately snatched out of his hand and tossed away by Rose. "Getting a bit too close to the 1980's"

"What am I gonna do? Put a dent in 'em?"

"Well, someone did," he said, looking at Rose.

"Oi!"

Then suddenly the phone that Martha gave Rose when she left that Tardis starts to ring and she took it out and opens it "Hello?" She said as Donna was confused on why Rose had two phones and the Doctor told her that the one Rose was using was a phone that Martha gave her for in case her phone broke beyond rapair.

"Rose? It's Martha," she heard her friends voice down the line. "Tell your husband that I'm bringing you two back to Earth."

"Martha?!" Rose cried in delight. "Oh Rassilon! Where are you?!"

The Doctor watched in happy surprise as Rose chatted as she ran around the console, putting in coordinates. He hadn't really expected to hear from Martha for a while. He missed her, but after what had happened last time, he wasn't surprised that she wanted to keep her distance. He could feel Rose's elation. It had been months since she'd last spoken to Martha, someone she considered to be one of her closest friends that are alive and human..

"Okay, we'll be right there!" she said, hanging up.

"Somebody's excited," Donna smirked.

"Damn right I am!" Rose said. "Donna, I think it's time you met Martha Jones!"

Martha stands in an alleyway as the Tardis materialises behind her and she turns around as the Doctor pops his head out he looks one way then the other and sees Martha and Rose then came out and looked in the same direction and she ran to her and hugs her.

"Oh my gosh, look at you! You look great!" Martha said as they stepped back.

"So do you!" Rose gushed. "Interesting outfit." The corners of her mouth twitched down, betraying her smile as a memory slipped through her head. That out fit seemed eerily reminiscent of a certain year best left forgotten... quite literally for most.

As Rose was pondering this, Martha spotted the Doctor. At first they were both calm as they walked towards each other. It seemed odd to watch that. She was so used to the idea of rushing into his waiting arms that she never really considered that this didn't really happen often with other people.

"Martha Jones," the Doctor said, fondly.

"Doctor," she said. Their faced seemed serious, but their eyes were twinkling with mirth, and in the next second the Doctor had opened his arms wide and swept her into a hug.

"Ah! Yeah!" he grinned happily as he lifted her up, then placed her back down. "You haven't changed a bit!" Rose raised an eyebrow. Really? Did he really think that? Because she could see quite a bit that had changed about her friend. She seemed good, better even, but something was off. The Doctor looked over at her when he felt her doubt.

"Neither have you!" Martha exclaimed, looking him up and down.

"He really hasn't," Rose said. "Well, looks anyway." The Doctor shot her a wink, knowing just how much she liked his looks.

"All right, that's enough you two!" Donna said as she comes out of the Tardis. "What have I said about doing that in public?"

They walk towards each other and hug.

"How's the family?" the Doctor said, quickly changing the subject and ignoring Donna all together. Donna just rolled her eyes at him.

"You know. Not so bad. Recovering."

"That's good," Rose said. "And Leo's still clueless."

"As ever!" Martha laughed. "Keeps wondering what got into us sometimes." She grinned at them uneasily, before her eyes settled on Donna again. "Oh, hello! I'm-"

"Martha Jones," Donna finished. "Rose has mentioned you quite a bit. And himself. I'm Donna. Donna Noble."

"I dread to think," Martha said.

"No, no, no. No," Donna said "They both say nice things. Good things. Nice things. Really... good things about you."

"Oh my god, the've told you everything."

"Hey, since when has that been there!" She cried.

"What?" Rose nodded to the gem on her left ring finger and she brought it up for all to see.

"You're engaged?" the Doctor exclaimed. "Really? Who to?"

"Tom. That Tom Milligan. He's in paediatrics working out in Africa right now."

"Tom from the year that never was?" Rose asked.

"Yeah."

"Oh! I knew you had a thing for him!"

"Yeah, well, I wasn't going to do anything more than that call. But then I got placed at the same hospital as him when UNIT pushed my training through. We just hit it off."

"Good on you!" She was about to say more, but she was cut off by the static sound of a walkie-talkie transmitting.

"Dr Jones, report to base, please."

"And speaking of which..." She picked up the radio at her hip and turned to walk the other way as she talked into it. "This is Dr Jones. Operation Blue Sky is go, go, go. I repeat, this is a go."

The three travellers looked at her in bewilderment. Rose felt dread rise up I her. This was so wrong. It was so familiar and it was so wrong. She found that she was becoming terrified of what her friend could be like now.

She had spent a year with Martha and watched her change into a cold, military like person... Had she been too naïve to hope that she would change when things went back to normal? Then again, things never did go back to normal, did they? The year had reversed, but they had not changed with it. It had been different for all of them. They had grown too much.

They followed Martha, watching in concern as UNIT members ran in, trucks drove about. Orders were being shouted out and Martha looked on with a steely coolness. UINT officers stormed into a nearby factory. Once again, she picked up the comm.

"Greyhound Six to Trap One. B Section, go, go, go! Search the ground floor, grid pattern Delta."

"What are you searching for?" The Doctor asked.

"Illegal aliens."

"Illegal?" Rose mouthed at him. He just shrugged in reply, his bottom lip sticking out slightly.

Martha ran off shouting commands into her comm. They looked about in horror as soldiers roughly handled the workers of the factory. Shouting at them, manhandling them, forcing the seemingly ordinary people onto their knees.

"Is that what you did to her?" Donna said quietly. "Turn her into a soldier?"

"No," Rose told her. "No, he didn't even know it was happening." Both of them looked at her, the Doctor hadn't realized that she knew Martha could be like this. "He didn't do this to her, the Master did."

"Who?"

"An old... friend of ours. He's dead now."

"And he did that to her?"

"You should have seen what he did to the world," Rose muttered.

They stood around in silence, just watching the goings on until Martha came back to them. That was when the Doctor noticed the badge pinned to her jacket. He'd been listening to the earlier conversation, but he hadn't really clicked on till now.

"And you're qualified now? You're a proper doctor."

"UNIT rushed it through given my experience in the field. Here we go." She led them across the grounds to the large black truck. "We're establishing a field base on site. They're dying to meet you."

"Wish that I could say the same," he muttered.

They were led into the back of the truck, which was surprisingly deceptive on the outside. Inside they were faced with a posh, high-tech headquarters. It didn't even look like they were still on the same truck. And if it weren't for the fact that the inside was about the right size, Rose would have thought they'd found a way to use technology from her and the Doctor's own people.

"Operation Blue Sky complete, sir," Martha said, waking over to a man in high-ranking uniform.

"Thanks for letting me take the lead. And this... this is the Doctor. Doctor, Colonel Mace."

"Sir." Colonel Mace stood rigid and raised his hand in salute.

"Oh, don't salute," he complained.

"But it is an honour, sir. I've read all the files on you. Technically speaking, you're still on staff. You never resigned."

"What? You used to work for them?" Donna said in surprise.

"Yeah. A long time ago. Back in the 70's... or was it the 80's?"

"He got Earthbound for a little bit, as he was exiled from our planet for interfering in the problems of other civilizations cause Time Lords and Time Ladies are meant to watch not to protect or interfere." Rose explained.

"It was all a bit more homespun back then." He looked about at all the computers and the workforce going on around them.

"Times have changed, sir," Colonel Mace told him.

"Yeah, that's enough of the 'sir'," the Doctor said

"Yeah, not a fan of that place," Rose muttered.

"We've got massive funding from United Nations, all in the name of Homeworld Security," Martha told them.

"A modern UNIT for the modern world," Colonel Mace added.

"What, and that means arresting ordinary factory workers in the streets in broad daylight? It's more like Guantanamo Bay out there. Donna, by the way. Donna Noble, since you didn't ask. I'll have a salute." The Doctor hid his grin as he took off his coat and chucked it over the desk.

Mace looked at the Doctor in bewilderment, and he gave a slight nod. "Ma'am!" He saluted.

"Thank you," Donna said. Rose grinned and shook her head. "You want one too, Rose?"

"No, thanks, I don't salutes like the Doctor, nor do I like guns," Rose said.

"Tell me what's going on in that factory," the Doctor said, now sitting down near the front.

"Yesterday, fifty-two people died in identical circumstances right across the world, in eleven different time zones," Mace said. As he spoke, points popped up on the screen, showing the locations of the deaths. "5am in the UK, 6am in France, 8am in Moscow, 1pm in China-"

"You mean they died simultaneously?"

"Exactly. Fifty-two deaths at the exact same moment world wide."

"How did they die?"

"They were all inside their cars."

"They were poisoned" Martha added. "I checked the biopsies. No toxins. Whatever it is, left the system immediately."

"What have the cars got in common?"

"Completely different makes, but all fitted with ATMOS. And that is the ATMOS factory."

"What's ATMOS?" Rose asked.

"Oh, come on, even I know that," Donna said. "Everyone's got ATMOS."

"Oh, Rassilon. It's like Archangel all over again," Rose groaned.

"Archangel? Wasn't that that network thing for your cellphone?"

"Yep, it was," Martha said, frowning.

"What was wrong with it?"

"It was made as a semi-psychic transmitter by a psychopathic alien."

"Can anything just be normal with you lot?" Donna said. "I mean, next you're going to tell me that there are aliens in parliament!"

"Well..." the Doctor shrugged. "There used to be. Anyway."

Soon they were being being led around the factory, watching everything from above on the catwalk.

"Stands for 'Atmostpheric Emissions System'. The ATMOS in your car reduces OC2 emissions to zero."

"Zero? No carbon, none at all?

"And you get sat-nav thrown in, plus 20 quid in shopping vouchers if you introduce a friend. Bargain," Donna told them.

"And this is where they make it, Doctor, shipping worldwide," Mace added. "Seventeen factories across the globe, but this is the central depot, sending ATMOS to every country on Earth."

"And you think ATMOS is alien?"

"It's our job to investigate that possibility. Doctor?" He walked off, and they followed, soon coming to another part of the factory, but this time on the ground floor. Mace indicated to a small metal box. "And here it is, laid bare. ATMOS can be threaded through any and every make of car."

"You must've checked it before it went on sale."

"We did," Martha said. "We found nothing. That's why I thought we needed and expert."

The Doctor put on his glasses and began to examine the ATMOS. "Really? Who did you get?" Everyone in the room looked at him with a raised eyebrow or amused expression. "Oh, right! Me, yes! Good."

"OK, so why would aliens be so keen on cleaning up our atmosphere?" Donna asked them

"Very good question," the Doctor said.

"Maybe they want to help," Donna suggested "Get rid of pollution and stuff."

"Donna, do you know how many cars there are on planet Earth?" Rose asked Donna, "800 million."

"Rose is correct there are 800 Million cars on Earth," the Doctor said "Imagine that. If you could control them, you'd have 800 million weapons."

A few minutes later the Doctor wears his glasses as he examines the components of the ATMOS device with his Sonic Screwdriver.

"Ionising nano membrane carbon dioxide converter, which means that ATMOS works. Filters the CO2 at a molecular level," he said.

"We know all that," Colonel Mace said "but what's its origin? Is it alien?"

"No. Decades ahead of its time," Rose said and the Doctor and Colonel Mace both bend over the ATMOS device "Look, do you mind, could you stand back a bit?" He asked Colonel Mace.

"Sorry, have I done something wrong?" He asked the Time Lord.

"You're carrying a gun," he answered "Me and Rose both don't like people with guns hanging around us, all right?"

"If you insist," Colonel Mace said, leaving, feeling offended.

"Tetchy," Martha said in annoyance.

"Well, it's true."

"He's a good man!" Martha argued.

"People with guns, except Jack are usually the enemy in my books," the Doctor said "You seem quite at home,Martha."

"If anyone got me used to fight it's you and Rose," Martha said.

"Oh, right, so it's our fault."

"Well, Doctor, you got me the job! Besides, look at me," she said and he stops what he was doing and looks at her "Am I carrying a gun?" She asked him.

"Suppose not," he said

"It's all right for you and Rose," she said "You both can just come and go, but some of us have got to stay behind. So I've got to work from the inside and by staying inside, maybe I stand a chance of making them better."

"Yeah?" He smiled, glad to be proven wrong. "That's more like Martha Jones."

"I learned from the best," she said, looking at both of the Doctor and Rose.

"Well..." the Doctor starts as Donna bursts in shoving the plastic curtains out of her way.

"Oi, you lot!" She yelled "All your storm troopers and your sonics... You're rubbish! Should've come with me."

"Why, where have you been?" The Doctor asked her. Mace reappeared beside them, alerted by all the noise she had made.

"Personnel. That's where the weird stuff is happening. In the paperwork. 'Cause I spent years working as a temp, I can find my way around an office blindfolded. And the first thing I noticed..." She held up a blue binder. "Is an empty file."

"Why, what's inside it?" The Doctor asked "Or what's not inside it?"

"Sick days." She showed them the label before opening it to show them. "There aren't any. Hundreds of people working here, and no one's sick. Not one hangover, man flu, sneaky little shopping trip. Nothing. Not ever. They don't get ill."

Rose raised her eyebrows. As her chameleon arched self have worked in a shop so she knew exactly what Donna meant. Everyone without fail would have a sick day of some kind.

"That can't be right," Colonel Mace said grabbing the folder from Donna.

"You've been checking out the building, should've been checking out the workforce."

"I can see why they like you," Martha smiled. The three of them exchanged a smug look. "You are good."

"Super-temp," Donna said cheekily.

"Need to get you a costume," Rose joked.

"Dr Jones, set up a medical post, start examining the workers," Colonel Mace ordered. "I'll get them sent through."

He walks off

"Come on, Donna. Give me a hand," Martha said. "Rose, wanna come too?"

"No, thanks, Martha, thanks for the offer though."

The Doctor grabs Rose's hand and they dashed after Colonel Mace

The Doctor runs after Colonel Mace. They walk along a corridor.

"So this, this ATMOS thing," the Doctor said "Where did it come from?"

"Luke Rattigan himself," Colonel Mace answered.

"And who's himself, then?" Rose asked. Mace looked them as if they were a bit daft, which he knew they weren't. "We're a bit out of the loop."

He nodded. "Follow me."

Colonel Mace had led them back to the trailer and called out orders to the computer staff. Soon a profile was pulled up of a boy in his late teens.

"Rattigan's right," Rose muttered. "Pointy face and beady eyes... got any rat poison, that should do the job." The Doctor tried to hide his laugh and he gave her a small bump to the side in warning.

'I was only joking,' she told her husband through their bond.

'I know but still, don't make jokes like that,' he replied.

'Ok, Theta,' she said and colonel Mace just huffed and rolled his eyes. Anyone would think he were working with children.

"Child genius," he said "Invented the Fountain 6 search engine when he was 12 years old. Millionaire overnight. Now runs the Rattigan Academy. A private school, educating students, handpicked from all over the world."

"A hothouse for geniuses."

"Sounds like fun," Rose said.

"Actually, I wouldn't mind going there." Mace looked at him, puzzled. "I get lonely," he said cheekily.

"So, are we going to some big fancy academy, then?" she asked.

"I'd say so, yeah," he said.

"Doctor, where are you going?" Colonel Mace's voice made him stop short and turn around.

"We told you, we're going to Rattigan's Academy. I'd quite like to check it out and find out more about this kid. Like how he knows about technology from the 24th century." He turned again, and they carried on walking. It didn't take long for Colonel Mace to fall into stride with them.

"Alright then, I will company you. We'll take my car," Colonel Mace told them.

"You are not coming with us. I want to talk to this Luke Rattigan, not point a gun at him." Rose gave him a small nudge. He was being just a little too bigoted at the moment. Of course, she had no idea what UNIT used to be like, or why the Doctor wasn't all too fond of them sometimes because she was chameleon arched and was sent to Earth in late April 1987.

"It's ten miles outside London. How are you going to get there?"

"Then get me a Jeep!"

"According to records, you travel by TARDIS."

"Not always a safe mode of travel," Rose informed the colonel. "The TARDIS is old, and with this one's driving, we could end up there next year by accident. Besides unlike him I passed the Driving test for Tardises."

The Doctor turned to her. "Are you ever going to let that go?"

"Never."

"Ugh," he growled, rolling his eyes before he turned back to Mace. "Besides, if there is a danger of hostile aliens, I think it best to keep a super-duper time travel machine away from the front lines."

"I see. Then you do have weapons, but you choose to keep them hidden."

"That's not what he-"

"Jenkins?!"

"Sir!" a young man called from not far away.

"You will accompany the Doctor and take orders from him."

"Yeah, I don't do orders," he said.

"Any sign of trouble, get Jenkins to declare a Code Red. And good luck, sir." He lifted his hand in salute once more.

"I said, 'no salutes'."

"Now you're giving orders," Mace said as he walked off. Rose cracked up laughing.

"A bit cheeky, you are," he said to the retreating colonel.

"Donna!" Rose said as she noticed the redhead walking towards them.

"Ooh! Donna! Just in time," he cried, rushing over to her and dragging her back towards Rose.

"Come on, come on. We're going to the country. Fresh air, geniuses, what more could you ask?"

"I'm not coming with you," she said. "I've been thinking. I'm sorry... I'm going home."

"But..."

"Really?" he said at the same time as Rose.

"I've got to," Donna said. At first Rose had been scared that Donna was leaving them for good,

what with the way she'd phrased it. But now, there was something in what she said that Rose recognised. She didn't look like she wanted to leave. She wasn't saying goodbye, she was saying she wanted a visit.

"Well, if that's what you want," the Doctor said. "I mean, it's a bit soon. I had so many places I wanted to take you. The Fifteenth Broken Moon of the Medusa Cascade, the lightening skies of Cotter Palluni's world, the diamond coral reefs of Kataa Flo Ko... Thank you. It's been brilliant. You – you've saved my life in so many ways." Donna nodded and rolled her eyes at Rose, making the blonde laugh. "You're... you're – you're just popping home for a visit. That's what you mean."

"You dumbo," Donna said.

"And then you're coming back." In the background, Rose couldn't stop laughing, making him feel even more embarrassed.

"Do you know what you are? A great, big, outer-space dunce!"

"Yeah."

"Oh god, he is," Rose giggled.

"Alright, you. I get it!" he said. Rose kept laughing. "Shut it!"

Rose bit her lip long enough to stop her laughing, but only so she would be able to speak. "Make me!" They looked at each other, heat and determination in their eyes. Donna could see this leading somewhere she didn't want to see very quickly.

"Ready when you are, sir," Jenkins informed them.

"And you now what else, you can give me a lift. Come on." The three of them smiled as they got into the Jeep. And then Donna looked at him oddly. "Broken moon of what?"

"I know, I know," he said.

The drive out was rather nice. Donna gave directions every now and then, otherwise she just sat back and listened. Rose held the Doctor's hand as he explained about what the Medusa Cascade and its twenty moons, sixteen of which were broken to Donna. With all the different lights and nebulas, they were a sight to see.

The fifteenth was half a chunk of the moon, and the rest was all fine fragments, trailing away from it like the tail of a comment. No one was sure how all of them were broken. But apparently he had broken one of them when the Tardis had gone off course which she don't remember that happened when they were still at the academy when they both went to the Medusa Cascade when they were 90 years old, so she figured it was after she was chameleon arched.

Soon the UNIT jeep pulls into a quiet road and the Doctor and Donna clamber out.

"I'll walk the rest of the way," Donna said "I'll see you and Rose back at the factory, yeah?"

The Doctor jumps back into the jeep, "Bye!" he yells.

"And you both be careful!" she yells back as the jeep pulls away leaving Donna on her own.

As they get closer to the academy, driving through the countryside "So then," Rose said, turning to their driver. "Jenkins. Got a first name?"

"Ross, ma'am," he replied.

"Ross... I like it. Much better than last name basis, too."

"Mmm, so," the Doctor said. "What can you tell us about this academy?"

"UNIT's been watching the Rattigan Academy for years," he said. "It's all a bit Hitler Youth. Exercise at dawn and classes and special diets."

'Turn left' the sat-nav told them. Rose tapped at it, noticing that the brand label on it said 'ATMOS'. She pointed it out to the Doctor.

"Ross, one question. If UNIT think that ATMOS is dodgy-"

"How come we've got it in the Jeeps?"

"Yeah."

"Ha, tell me about it. They're fitted as standard on all government vehicles. We can't get rid of them until we can prove there's something wrong."

'Turn right.'

"Drives me around the bend," he said at the same time.

"Oh, nice one!"

"You timed that perfectly," Rose laughed. "But I get you, I wouldn't really be a fan of one of these things. Could you imagine one of those in the TARDIS? Twist the paperweight left. Three seconds to the 18thcentury."

"I think it's a little more complicated than that," the Doctor rolled his eyes, hiding his smile. At this point, they drove up the driveway of the academy and the full thing came into view.

'This is your final destination.'

"Mmm, fancy," Rose said. "Did that used to be a castle?"

"He's got quite the set up, doesn't he?"

They climbed out of the Jeep and started off towards the building. The academy was surrounded by a vast amount of lawns. A bunch of people in red tracksuits were jogging around the property. And a young man stood watching them, dressed simply in jeans and a t-shirt.

"That's him," Ross said, nodding to the man in casual dress. They continued up the path, only turning off it when they neared him.

Is it PE?" the Doctor asked him. "I wouldn't mind a kick-around. Got my daps on." Rose snorted at this.

"I suppose you're the Doctor," Luke said, turning to face them.

"Yep. Hello. And this is my wife, Rose.

"You're commanding officer phoned ahead," Rattigan cut him off. The disdain on his face was very clear.

"Oh, I haven't got a commanding officer. Have you?" The boy just stared at him stonily. "Oh, this is Ross. Say hello, Ross."

"Afternoon, sir," Ross nodded.

Excitedly, the Doctor grabbed Rose's hand and bounced towards the big doors. "Let's have a look, then! I can smell genius... in a good way."

Luke rolls his eyes behind the Doctor and Rose as he follows them in to a room full of students performing experiments with very advanced equipment for the 21st century..

"Oh, now!" the Doctor said enthusiastically as they walked into the room. "That's clever, look!" He slipped on his glasses so he could get a better look at the experiments. Soon he dashing all over the room to look at them. "Single-molecule fabric. How thin is that?! You could back a tent in a thimble. Oh! Gravity simulators! Terraforming, biospheres, nano-tech steel construction! Ha-ha, this is brilliant!" Rose looked up from tapping a glass ball filled with colourful glowing gasses to grin at him. This room was probably Christmas for him. "But you know," he carried on, now looking at Rattigan. "With equipment like this, you could, oh, I dunno... move to another planet or something."

"If only that was possible," Luke said

"If only that were possible," the Doctor corrects him, taking his glasses off. "Conditional clause."

Rattigan's face contorted, as if he was trying to restrain a glare. Instead he stiffened up, head held high. "I think you better come with me." The Doctor raised his eyebrows at Ross and Rose, he clearly found the boy a piece of work. He led them out of that room and into another not too far away. This room was huge and lavishly decorated. "You're smarter than the usual UNIT grunts, I'll give you that."

"A grunt?!" Rose almost laughed. When talking about the Doctor, a grunt is the last thing that would come to mind.

"He called you a grunt!" the Doctor said to Ross, sounding very offended. "Don't call Ross, a grunt, he's nice. We like Ross. Look at this place..."

"What exactly do you want?" Rattigan suddenly snapped at them.

The Doctor began to wander about, still looking at the big room. "I was just thinking, what a responsible eighteen year old. Inventing zero-carbon cars. Saving the world..."

"It takes a man with vision."

"Mmm, blinkered vision. 'Cause ATMOS means more people driving, more cars, more petrol, end result: the oil's going to run out faster than ever. The ATMOS system could make things worse."

"Yeah. Well, see, that's a tautology," he said speaking very fast, sounding a lot like a bratty little child. "You can't say ATMOS system, because it stands for 'Atmospheric Emission System'. So you're saying 'Atmospheric Emission System System'. Do you see, Mr Conditional Clause?"

"It's been a long time since anyone's said no to you, isn't it?" the Doctor said evenly.

"I'm still right, though."

"Not easy, is it? Being clever?" the Doctor said to him. "You look at the world and you connect things, random things, and think, 'why can't anyone else see it? The rest of the world is so slow'."

"Yeah."

"You're on your own."

"I know."

"But not with this," he suddenly said in a brighter tone, pulling an ATMOS device from his pocket.

"'Cause there's no way you invented this single-handed. It might be Earth technology, but that's like finding a mobile phone in the Middle Ages." He tossed it to Ross, who quickly caught it, then he headed towards the big odd purple square thing that sat in the room. "No, no. I'll tell you what it's like! It's like finding this in someone's front room. Albeit, a very big front room."

"Why? What is it?" Ross asked him.

"Doctor, is that what I think it is?" Rose asked her husband.

"You're correct, Rose," he answered "And just looks like a thing, doesn't it? People don't question things, they just say: Oh, it's a thing."

"Leave it alone!" Rattigan shouted at him.

"Me, I make these connections," he said, walking inside it. "And this to me looks like..." he pressed a button. "A teleport pod." Then he disappeared in a spark of light from the academy.

He reappears on a large futuristic spaceship. there was a bright purple light lit up and there are Sontarans milling around.

'Orbit now holding at 555.3, sector 270.' a computerized voice said.

"Oh..." the Doctor said.

The Sontarans all turn to notice him, and one of them raises his staff.

"We have an intruder!" the sontaran said.

"How did he get in? In-tru-da window?"

The Sontarans begin to charge towards the Doctor.

"Bye!" He presses the control pad again, and begins to run just as he teleports away. He appears back at Rattigan Academy, still running.

"Ross, get out. Luke, you'd better come with me!" He grabbed Rose's hand and pulled her back with him.

the teleport pod lit up again and someone very short covered in armour stepped out. and Rose grabs her screwdriver and zapped the teleport with it.

"Sontaran!" he shouted at them. "That's your name, isn't it? Your a Sontaran. How did I know that, eh? Fascinating, isn't it? Isn't that worth keeping me alive?"

"I order you to surrender in the name of the Unified Intelligence Taskforce," Ross said immediately, aiming his gun at the alien.

"Well that's not going to work," Rose said "Cordolaine signal, am I right? Copper excitation stopping the bullets."

"How do you both know so much?"the Sontaran demanded. His voice was rather rough and sounded kind of odd

"Well..." the Doctor said, walking back and leaning against Luke's desk.

"We're aliens!" Rose interjected

"Aliens..." the sontaran muttered to himself. He turned to Luke "Who are they?"

"He didn't give his name but he said that she is his wife, Rose."

"This isn't typical Sontaran behaviour, is it?" the Doctor went on. "Hiding? Using teenagers? Stopping bullets? A Sontaran should face bullets with dignity! Shame on you!" He was clearly mocking him.

"You dishonour me, sir!" the Sontaran said, his tone stiff and offended.

"Yeah, then show yourself."

"I will look into my enemy's eyes." He reached up and removed his helmet with a soft hiss. When it was off, they were faced with a brown-ish dome shaped head. He didn't seem to have a neck, he just looked like... well, a lump with a very angry face.

"Oh my God," Ross gasped.

"Finally I met a sonaran!" Rose said, learning about them at the Academy on Gallifrey.

"And your name?" The Doctor asked.

"General Staal, of the Tenth Sontaran Battle Fleet. Staal the Undefeated," he replied proudly.

"That's not a very good nickname. What if you do get defeated? "Staal the Not-Quite-So-Undefeated-Anymore-But-Never-Mind?" At this, Rose grinned, a bit of a giggle escaping, and Ross scoffed.

"He looks like a potato," Ross said. "A baked potato. A talking baked potato."

"Now, Ross, don't be rude. You look like a pink weasel to him," the Doctor said as he goes and picks up a racket and begins bouncing a small ball upon it. "The Sontarans are the finest soldiers in the galaxy, dedicated to a life of warfare. A clone race, grown in batches of millions with only one weakness..."

"Sontarans have no weakness!" General Staal said, angrily.

"No, it's a good weakness!" The Doctor defended.

"Thought you were meant to be clever?" Luke asked "Only an idiot would provoke him."

"Only an idiot would work with him," Rose fired back. Rattigan clenched his fists in anger, but yet again, the Doctor continued, playing with the ball and racket all the while.

"No, but the Sontarans are fed by a probic vent in the back of their neck, that's their weak spot," the Doctor said "Which means, they always have to face their enemies in battle... isn't that brilliant? They can never turn their backs!"

"I think it is brilliant," Rose said.

"We stare into the face of death!" Staal shouted

"Yeah?" The Doctor challenged "Well, stare at this!"

He suddenly hit the ball behind Staal. It bounced off the back of the teleport pod and straight into where the probic vent was. Staal staggered and cried out. They didn't stay to see him fall to the floor, they sprinted out. Luke crying out behind them. They kept running till they reached the Jeep. Quick as the could, they piled in and drove off.

Please review and tell me if I'm making Rose sound like well... Rose. Because I don't know how to write her properly. And I still need a Beta-reader.
