Thanks to Bunny's daughter, Alex0127, Bikutoria08, Etheri0n, NiloSea, TheGuardianoftimeandspace, arielle. Dawnn, nomohakon for following/faving my story.

A (Guest): that you'll just have to wait and see. I've never watched any of the classics. I got into it when the new ones started with Eccelston.

The asian teenager watched, horrified as everyone was being electrocuted. What do I do? What do I do? Kit frantically thought. There had to be a way to stop the Slitheen….her eyes widened when it hit her. The note! It had told her what to do!

Gripping the ID card tightly in her hand, she darted towards one of the Slitheen, ignoring the Doctor's rather strained shouts for her to stop. The blackette slammed the ID onto the collar around the neck of Asquith the Slitheen. Both he and Joseph howl in pain as they're both electrocuted. "Take that ugly", she spat glaring at them before she hurried over to the Doctor's side. She grabbed his arm and with some effort managed to haul him to his feet.

They went out to the reception area were armed soldiers were waiting "Oi! If you want aliens, you've got them", the Doctor said to them "They're inside Downing Street" he claps his hands "Come on!"

The armed police followed him and Kit back to the briefing room where unfortunately both Slitheens were back in their skin suits. "Where have you been?" Joseph demanded "I called for help. I sounded the alarm. There was this…lightening, this kind of er…um…electricity, and they all collapsed!"

The police men check all the experts for a pulse "I think they're all dead", Sergeant Price stated.

"That's what I'm saying. They did it!" Joseph said pointing at the Doctor and Kit.

"I think you will find the Prime Minister is an alien in disguise", the Doctor said. Joseph folds his arms sceptically. "That's never going to work, is it?" he asked his new friend.

Kit shook her head "I'm afraid not", she reluctantly answered.

"Fair enough", the Doctor said. He grabbed her hand and then they ran.

They didn't manage to get very far when they came face to face with several armed men. Another group of soldiers came up behind the time travellers. General Asquith pushed his way through the soldiers. "Under the jurisdiction of the Emergency Protocols, I authorise you to execute this man and girl", he ordered.

The armed police men ready their guns. "Well, now, yes, you see, eh… the thing is, if I was you… if I was going to execute someone by backing them against the wall, between you and me, little word of advice" there was a ding and the door opened behind Kit and the Doctor "Don't stand them against the lift!"

The Time Lord pulled her backwards into the lift and closed the door using his sonic screwdriver. "That was a close one. is it always like this?" the teen keeping up the pretence. She knew 80% of his adventures were always like this one.

"Pretty much", the Doctor replied "Kit…I was wondering, when this is over would you like to come with me?" he asked, hoping she would say yes so he could figure out why the mystery teen had wanted him to meet her in the first place.

Kit's inner self squealed with excitement. This is what she's always wanted! On the outside she maintained a fairly calm composure, though it was very difficult to do so. "Really?" she asked "Is it like a one trip kind of deal or..?"

"Nope! You can stay as long as you want", the Time Lord said.

The 19 year old smiled "I'd love to! Thank you Doctor!" she hugged him happily.

"Your welcome, Earth Girl", the two hearted alien said, happy that she said yes.

The blackette rolled her eyes "You're going to keep calling me that aren't you?"

"You called me Spaceman first remember?" the Time Lord reminded her.

"Yeah but I…" the blackette broke off when the lift doors suddenly open revealing Margret the Slitheen. Behind her they could see Rose and an older woman trying to get into a room. Margret roars at the pair but the Doctor just smiled pleasantly at her.

"Hello!" he said cheerfully and closed the lift doors again.


The Doctor and Kit got off the lift when it stopped again, this time on the second floor. They made their way along the hallway and down a step of stairs. The Doctor and Kit stopped they heard the lift dinging. The Time Lord Doctor took the blackette over to a crevice between the wall and the door.

Kit held her breath as two Slitheen walked past, talking "It does us good to hunt. Purifies the blood".

"We'll keep this floor quarantined as our last hunting ground before the final phase", Joseph added.

The 19 year old relaxed the second the Slitheen were gone. "That was close", she murmured, the Doctor humming in agreement. The pair went in the same direction as the Slitheen hoping to find Rose before the large green aliens found her. "Which room is she in?" Kit asked. She got her answer in the form of a scream. It was coming from the room ahead. The Time Lord grabbed the fire extinguisher sitting near the door and burst in. He sprays the two Slitheen closest to the door with it.

"Out, with me!" he shouted. Rose yanked the curtain down over the Slitheen near to her and ran out, an older woman following. After a quick introduction of the woman who introduced herself as Harriet Jones, the four of them ran. "We need to head to the Cabinet Room", the Doctor told them.

"The Emergency Protocols are in there. They give instructions for aliens!" Harriet exclaimed.

"Harriet Jones, I like you", the Time Lord remarked.

"And I like you too", the woman said.

During their run, the Doctor bypassed a locked door with his sonic and they all run into the Cabinet Room. The Time Lord ran over to the doorway and snatched up a decanter of alcohol from the table. He holds his sonic against it as the aliens approached "One more move and my sonic device will triplicate the flammability of this alcohol. Whoof! We all go up. So back off", he threatened. The alien trio did so "Right then. Question time. Who exactly are the Slitheen?" the Doctor asked.

"They're aliens", Harriet stated.

"Yes. I got that, thanks", the Time Lord said, slightly sarcastic.

"Who are you, if not human?" Joseph questioned, eyeing the alien.

"Who's not human?" Harriet frowned.

"He's not human", Kit told the MP.

"He's not human?" Harriet repeated, eyes wide.

"Can I have a bit of hush?" the Doctor asked wanting to get back to his questioning.

"Sorry", the woman mumbled, apologetically.

"So, what's the plan?" the Time Lord questioned.

"But he's got a Northern accent", Harriet protested. Kit rolled her eyes, getting a little annoyed at her interruptions.

"Lots of planets have a north", she stated earning a weird look from Rose. How did she know that? the blonde thought. That was something the Doctor had said when she asked about his accent. But it wasn't possible for Kit to know was it? She only knew him for like…five minutes!

"I said hush. Come on!" the Doctor held the decanter of alcohol threateningly out in front of him "You've got a spaceship hidden in the North Sea. It's transmitting a signal. You've murdered your way to the top of government. What for, invasion?"

"Why would we invade this God-forsaken rock?" Asquith asked.

"Then something's brought the Slitheen race here. What is it?" the two hearted alien queried.

"The Slitheen race?" General Asquith asked sounding rather offended.

"Slitheen is not our species. Slitheen is our surname", Joseph said, correcting the Doctor "Jocrassa Fel Fotch Pasameer-Day-Slitheen at your service".

"That's a bit of a mouthful", Kit commented.

"So, you're family", the Time Lord stated.

"It's a family business", Joseph confirmed.

"Then you're out to make a profit. 'How can you do that on a God-forsaken rock'?" the Doctor pressed, wanting to know more.

"Ahhh…excuse me?" Asquith said gesturing to the decanter "Your device will do what? Triplicate the flammability…?"

"Is that what I said?" the Time Lord asked, innocently.

"You're making it up", the Slitheen accused.

"Ah, well! Nice try. Harriet, have a drink. I think you're gonna need it" the Doctor held out the decanter not noticing that she had her arms full with the red case she was clutching.

"You pass it to the left first", she informed him.

"Sorry" he hands it to Kit who put it aside. She'd never drunk alcohol and she wasn't about to start.

"Now we can end this hunt…with a slaughter" Asquith flexed his claws menacingly.

"Don't you think we should run?" the blackette asked the Doctor, setting aside the decanter of alcohol.

"Fascinating history, Downing Street. Two thousand years ago, this was marsh land. 1730, it was occupied by a Mr Chicken. He was a nice man. 1796, this was the Cabinet Room. If the Cabinet's in session and in danger, these are about the four most safest walls in the whole of Great Britain" the Time Lord lifted a panel and pressed a button "End of lesson" metal shutters slammed down in front of the doors and around the windows "Installed in 1991. Three inches of steel lining every single wall. They'll never get in".

"That was a good idea", Kit remarked "though…if they can't get in. How we get out?"

There was a pause. "Ah", the Doctor said releasing that while the Slitheen couldn't get in the room, they couldn't get out. Not with the metal shutters covering the doors and windows. The strode over to the table, the others following. "Right, what have we got? Any terminals, anything?" the Time Lord questioned, wanting to know what he had to work with.

Harriet shook her head "No. This place is antique", she replied.

"What I don't get is, when they killed the Prime Minister, why didn't they use him as a disguise?" Kit questioned, perching on the table, swinging her converse clad feet.

"They're big old beasts. They need to fit inside big humans", the Doctor told her.

Her almond shaped eyes widened "But the Slitheen are at least 8 feet tall! How do they fit inside?"

"That's the device around their necks. Compression field" the Time Lord explained "Literally shrinks them down a bit. That's why there's all that gas. It's a big exchange".

"Wish I had a compression field", Rose commented "I could fit a size smaller". Kit frowned at her, this wasn't the time to be making jokes! People were dead for Christ sake!

As if Harriet had heard what she was thinking, she said "Excuse me, people are dead! This is not the time for making jokes" in a tone of voice which all but scolded the blonde.

"Sorry. You get used to this stuff when you're friends with him" Rose nodded to the Doctor who'd by this point moved over to the walls to scan with his sonic.

"Well, that's a strange friendship" Harriet remarked.

"Harriet Jones, I've heard that name before", the Time Lord muttered "Harriet Jones. You're not famous for anything, are you?"

"Hardly", Harriet scoffed.

"Rings a bell. Harriet Jones…" the Doctor said to himself.

"Lifelong backbencher, I'm afraid", Harriet said "And fat lot of use I'm being now, the protocols are redundant. They list people who can help and they're all dead downstairs".

"Hasn't it got like, defence codes and things? Can we just launch a nuclear bomb at them?" Rose asked causing not only Harriet to stare at her but Kit as well. What is wrong with her? the black haired teen thought. This wasn't the Rose she'd seen in her dreams. Then again she'd only had like three dreams with the blonde featured so she couldn't really say for sure what she was like entirely.

"You're a very violent young woman…" Harriet remarked.

"I'm serious! We could!" Rose insisted.

"Well, there's nothing like that in here", Harriet said going through the contents of the red case "Nuclear strikes do need a release code, yes. But that's kept secret by the United Nations".

The Doctor stopped scanning the mantelpiece with his sonic to listen "say that again"

"What, about the codes?" Harriet asked.

"Anything", the Time Lord replied "All of it".

"Um, well…the British Isles can't gain access to atomic weapons without a Special Resolution from the UN", Harriet told him.

"Like that's ever stopped them", Kit commented.

"Exactly, given our past record. And I voted against that, thank you very much", Harriet said "The codes have been taken out of the government's hands and given to the UN. Is it important?"

"Everything's important", the Doctor said.

"If we only knew what the Slitheen wanted. Listen to me, I'm saying 'Slitheen' as if it's normal", Harriet said.

"What do they want, though?" Kit questioned.

"Well, they're just one family, so it's not an invasion", the Time Lord answered, his mind working through the possibilities "They don't want Slitheen World…they're out to make money. That means they want to use something. Something here on Earth…some kind of asset".

"Like what? Gold? Oil? Water?" the blackette suggested, listing off a few suggestions.

"Not sure. But those a good suggestions Earth Girl", the Doctor said.

"Thanks", Kit said, pleased though she was still irked at the fact he was still calling her Earth Girl.

A phone suddenly beeped "Oh, that's me", Rose said pulling her phone out.

"But we're sealed off. How did you get a signal?" Harriet asked.

"He zapped it! Super phone", Rose said. Ah, the universal roaming the asian teenager thought. Being able to call from anywhere in Time and Space sounded like a very good and very cool idea. Probably would make the phone work really well on Earth too…no more crappy signal.

"Then we can phone for help! You must have contacts", Harriet said hopeful.

"Dead downstairs, yeah", the Doctor said, sombrely.

"It's Mickey", the blonde said, checking the ID on her phone.

"Oh, tell your stupid boyfriend we're busy", the Time Lord grumbled. This wasn't the time for a social call.

"Yeah, he's not so stupid after all", Rose, showing them the phone. On the screen was a picture of a Slitheen.


"No, no, no, no, no. Not just alien, but like, proper alien. All stinking, and wet, and disgusting. And more to the point, it wanted to kill us!" Mickey exclaimed when Rose rung him up.

"I could've died!" Jackie cried.

"Is she all right, though? Don't put her on, just tell me", the younger blonde demanded to Mickey, ignoring her mother.

The Doctor snatched the phone from her "Is that Ricky?" he asked "Don't talk, just shut up and go to your computer".

"It's Mickey", Mickey said correcting him "and why should I?"

"Mickey the Idiot, I might just choke before I finish this sentence, but, er, I need you…" the Time Lord then told the man to go onto the UNIT website.

"It says password", Mickey said.

The Doctor plugged the phone into the conference phone speaker "Say again"

"It's asking for the password", the man repeated.

"Buffalo. Two Fs, one L", the Time Lord told him.

"So, what's that website?" Jackie asked Mickey.

"All the secret information known to mankind", the black man answered "See, they've known about aliens for years. They just kept us in the dark".

"Mickey, you were born in the dark", the Doctor said, somewhat rudely.

"Oh, leave him alone", Rose said, defending her boyfriend.

"Thank you. Password again", Mickey said, pleased she'd come to his defence.

"Just repeat it every time", the Time Lord replied. "Big Ben. Why did the Slitheen go and hit Big Ben?" he asked.

"You said to gather the experts, to kill them", Harriet reminded him.

The Doctor shook his head "That lot would've gathered for a weather balloon. You don't need to crash land in the middle of London".

"The Slitheen were hiding and then they put the entire planet on red alert. What would they do that for?" Kit asked. Before he could answer her, Jackie interrupted.

"Well, I've got a question, if you don't mind. Since that man walked into our lives, I have been attacked in the streets. I have had creatures from the pits of hell in my own living room, and my daughter disappear off the face of the Earth"

"I told you what happened", Rose said, somewhat exasperated. Her mother just didn't get it! She didn't understand that while it was dangerous, she loved this life. She loved travelling with the Doctor.

"I'm talking to him. 'Cos I've seen this life of yours, Doctor. And maybe you get off on it, and maybe you think it's all clever and smart, but you tell me" Jackie said "Just answer me this. Is my daughter safe?"

The Doctor stares intently at the phone "I'm fine", Rose insisted.

"Is she safe?" the Time Lord looked up at Rose, his mind immediately going back to that moment where they were trapped with the Gelth "Will she always be safe? Can you promise me that? Well, what's the answer?"

He didn't answer her. He would try and keep Rose safe, of course he would. But he couldn't make that promise to Jackie because there was no guarantee that he could keep her daughter safe. The only way to make sure that she was always safe, would be if she stopped travelling with him. And somehow he didn't think Rose would give it up any time soon.

His thoughts were broken when Mickey told them that he'd gotten onto the website. The Doctor gave him instructions and soon they were listening to a strange sound. The Time Lord tried to listen to it but there was an interruption from the door bell ringing on Mickey and Jackie's end.

"It's him! It's the thing, it's the Slipeen!" Jackie suddenly shouted.

"They've found us", Mickey added.

"Mickey, I need that signal", the Doctor urged.

"Never mind the signal, get out! Mum just get out! Get out!" Rose shouted worried for her.

"We can't. It's by the front door", Mickey said. A moment later he added in a panicked voice "Oh, my God, it's unmasking. It's going to kill us".

"There's got to be some way of stopping them! You're supposed to be the expert, think of something!" Harriet exclaimed.

"I'm trying!" the Doctor snapped.

"Hey, calm down", Kit said gently, putting a hand on his arm "to stop them we need to find out their weakness. How do we do that?"

The Time Lord looked at her, feeling much calmer than before. He was grateful that the mystery girl had brought her to his attention. It was fun to have someone whom he could banter with...who can ground him when a situation goes out of his control. And he'd only known her 5 minutes! Imagine what days...weeks...months would bring!

"To find out their weakness, we need to find out where they're from", the Doctor replied "So, judging by their basic shape, that narrows it down to five thousand planets within travelling distance. What else do we know about them? Information!"

Between Rose, Kit and Harriet, they'd given him enough to whittle it down to one planet: Raxacoricofallapatorius!

"Try saying that after you've had a few drinks", Kit said, trying to lighten the mood earning her a grin from the Doctor. He then instructed Mickey to go to his kitchen to look for anything with vinegar.

"What do you need?" Jackie asked having taken the phone from Mickey after he couldn't find anything with vinegar in it.

"Anything with Vinegar!" the Doctor answered. Jackie listed off items over the phone as she added them to the plastic jug. Kit screwed her nose up at the mention of pickled eggs. The Time Lord shoots Rose a somewhat curious look. "You kiss this man?" he remarked but the blonde just ignored him. They all listened as there was a crash followed by what sounded like a muffled fart and explosion.

"Mickey, mum are you two ok?" Rose asked.

"We're fine" came Jackie's voice which relieved the 19 year old.

Minutes later they were all listening to Green and Asquith spin a rather tall tale via phone connection with Mickey "Maybe their collar thing is on the fritz", Kit remarked, fiddling with the triple moon ring on her finger "there IS no threat in space. The only threat are them".

"Do you think they'll believe him?" Harriet asked.

"They did last time", Rose replied.

"That's why the Slitheen went for spectacle. They want the whole world panicking, because you lot, you get scared, you lash out", the Doctor said.

"The Slitheen get the defence codes and have a party…a party where the fireworks are nuclear weapons", Kit said, seriously "the world goes boom. We all die and the Slitheen make a profit from the leftovers". The Doctor looked at her, eyes wide. "What? It's just a guess", the blackette said, not sure why he was looking at her as if she'd solved an impossible math problem.

"You, Miss Vulpes, are a genius!" the Time Lord proclaimed. Rose barely refrained from rolling her eyes. Puhlease! That girl was hardly a genius. Just got lucky, that's all. "Now I have a way out but…"

"But…?" Rose urged.

"There's no guarantee we'll all get out alive", the Doctor said seriously.

"Don't you dare. Whatever it is, don't you dare", Jackie said. She did not want to lose Rose.

"That's the thing. If I don't dare, everyone dies", the Time Lord shot back.

"Do it", Rose piped up.

The Doctor looked up at her "You don't even know what it is. You'd just let me?" he asked.

"Yeah", the blonde replied, simply.

"Me too", Kit agreed. She'd seen him make tough choices in her dreams and he comes out of it alright…most of the time. Regardless, she still trusted him.

"Please, Doctor. Please. She's my daughter, she just a kid", Jackie pleaded.

"Sometimes the only choices you have are bad ones", Kit stated "but you still have to choose".

"You can't condone this! You're just a kid too! Your whole life is ahead of you!" Jackie exclaimed "what would your family say if they could hear you now!"

"Hard to say since I never knew my real family", the asian teenager shot back "in regards to my adopted mother, she'd probably kill me herself if I even contemplated sacrificing myself. However, this is MY life. Mine. And I will happily give up my life in order to save the woman who saved me. So let me ask you something Mrs Tyler, if the roles were reversed and you were here, what would you choose?" there was a pause on the other end of the line "that's what I thought" she looked at Rose "you would do anything to protect her. And she would do the same" the blonde nods "so just this once…let her save you" she glanced at the Doctor "do what you need to do".

"Are you sure?" the Time Lord asked. He felt moved by what she'd said and rather amazed too. This girl was willing to give up everything…everything to save her adopted mother.

"I'm sure", Kit confirmed, trying to ignore how her heart began to hammer away in her chest. She might've sounded like she'd accepted he decision she had just made but in truth she was scared. She was downright terrified about the prospect of dying. She refused to show it though because she knew she had to be strong.

"So how do we get out?" Rose spoke up.

"We don't. We stay here", the Doctor replied. He then told Mickey to do.

"How solid are these?" Harriet asked checking the walls.

"Not solid enough. Built for short range attack, nothing this big", the Doctor replied.

"All right, now I'm making the decision. I'm not going to die. We're going to ride this one out. It's like what they say about earthquakes. You can survive them by standing under a doorframe. Now, this cupboard's small so it's strong", Rose explained.

"We can ride out the explosion in the cupboard", Kit added.

"Exactly", Rose agreed. She and Kit then started to empty the cupboard to make room for the four of them.

"Harriet we could use your help here!" Kit called as the woman hadn't moved. After she said that however, Harriet did join them in emptying out the cupboard. Once finished they all get inside the cupboard, linking hands with one another.

"Nice knowing you", the MP said, taking hold of Rose's hand "Hannibal!" she shouts as they brace themselves.

BOOM!

Kit closed her eyes, tightening her grip on the Rose's hand as the cupboard rolled around several times before coming to a stop. "Made in Britain!" Harriet cheered after the Doctor pushed the door off the Cabinet Room. They all clambered out, one after another. "Oh, my God. Are you all right?" a soldier asked running up to them. Harriet pulled out her ID.

"Harriet Jones. MP, Flydale North. I want you to contact UN immediately. Tell the ambassadors the crisis is over. They can step down. Go on, tell the news", she ordered.

"Yes, ma'am", the soldier said.

"Someone's got a hell of a job sorting this lot out", Harriet gasped "Oh, Lord. We haven't even got a Prime Minister!"

"Maybe you should have a go", the Doctor suggested.

"Me? I'm only a back-bencher", Harriet said waving off their suggestion.

"I'd vote for you", Rose said.

"Same here", Kit agreed.

"Now, don't be silly", the MP scoffed "Look, I'd better go and see if I can help. Hang on!"

The three of them watched Harriet talking to a crowd of people for a moment before turning and walking off "I thought I knew the name", the Doctor says as they walked.

"Who?" Kit asked.

"Harriet Jones. Future Prime Minister. Elected for three successive terms, the architect of Britain's Golden Age", the Time Lord told her.


Sometime later…

Emma touched the glass protecting the photograph sadly. She hated the fact that it was the single reminder that she and the Doctor had. Well, technically it was the only thing that she had as the Time Lord didn't have a clue that she'd manage to save that particular picture. She understood him hurting. It was hard for her too. So she just couldn't get her head around the fact that he wanted to get rid of everything that reminded him of what he had lost.

Sometimes I think I mourn her more than he does the blackette thought, wiping away a tear. The TARDIS' lights suddenly flashed and Emma quickly stashed the photograph behind a cushion of the chair she'd been sitting in. Moments later the Doctor entered the room.

"Fancy a trip to Cardiff?" he asked.
