I was so glad to hear your feedback on the previous chapter. Thank you all. And thank you, ElfDrake for pointing out my few mistakes. Seriously, people. If you see nonsense written, then, please, write to me about it. I really don't wanna leave my horrible typos laying down there. ;D

And here comes our little chapter. Hope it doesn't disappoint any of you.

Thud

Blon dropped the body from her grasp, as she felt high volt of electricity run through her body. It was the chance to get away. Rose grabbed Harriet's hand into hers and pulled her away from the wardrobe, towards the doors. She could hear the future Prime Minister gasp, when she saw the Slitheen squeal and struggle, from the shock she was getting.

They ran through the corridors. Taking turn after turn. It had been a while since Rose was last here. Great. It seems she was lost. "No, wait." Harriet Jones' voice stopped her into her tracks. "The emergency protocols! They're still in there. We need them!" Harriet said, desperation in her voice. Before Rose could react, the woman was already making a turn to the room where the Slitheen was.

"Wait!" Rose yelled out. But it was too late. Harriet came to a stop, when she saw the Slitheen there and quickly exited the room, running from its sight. They dashed through one door just to exit another one, as the alien kept following them with high speed and strength, breaking through any barriers.

Okay, Rose. Think, think. Where is the safe place to hide now...

Ring

The elevator sound disturbed her thoughts.

"Doctor!" she shouted out to him.

"Hello." The Doctor greeted them both and the Slitheen, which was cornering him into the lift. In a second he buzzed his sonic screwdriver to close the lift. Soon enough, the Slitheen from the lift were following Harriet and Rose instead. Brilliant.

Once they got inside the room, Rose didn't bother to check the doors, since she knew that none of the doors in this room were open. She hid herself besides the curtain with Harriet close to her. Okay. Just a moment and Doctor should come with the fire extinguisher. She would have gotten it herself, but then again, she didn't know the place of where it was kept and maybe by taking it before the Doctor she would put him in danger instead.

"Well, this has worked out the last time. Should be the same now," Rose muttered under her breath, making a nervous laugh sound. Moments later, she could hear as Margaret entered the room and started talking with her sweet voice.

"You are such fun. Little human childreeen. Where aaare youuu?" she sang.

Oh, Rose hated this alien. She wondered if she made the right choice by giving her her second chance for the second time. She observed the room for any weapons, but soon thought otherwise, when two more Slitheen entered the room. She was clearly outnumbered. In a few steps Blaine made her way to Rose and pulled the curtain open to reveal the human there.

It came to a bit of a shock to her, when she saw only a disappointed expression on the girl. "What's it with you, little human?" She began, curiously, glancing Rose from head to toe. "I don't smell fear from you..." Her face was beginning to look angrier, if her face could show any emotions altogether.

"I don't fear you, Slitheen." Rose gave her a smirk, which seemed to offend Blon even more.

"Then I shall show you, where you were wrong, my dear." And the next moment she was already pointing her claws at Rose. For a moment Rose could feel her heartbeat quicken a bit. Fat lot of good you are. Rose chided her body.

"NOO!" Harriet's voice echoed inside the room. "Take me, FIRST!" Her hands pulled in the air.

And with those words, the doors burst open, the Doctor running inside with a big fire extinguisher in his hands. As expellant gas emitted from the extinguisher into aliens' faces, Rose didn't need to be asked twice to get out of the room. But just before exiting, she pulled the curtain on Blon and kicked her in the legs to see her fall down on the ground.

When they gone out of the room, only then the Doctor seemed to notice Harriet. "Who the hell are you?" he asked in wonder.

"Harriet Jones. MP of Flydale North," she announced.

"Nice to meet you," the Doctor said lightly.

"Likewise." Harriet rushed her response as they were running towards the cabinet room. Behind their backs, the three Slitheen were jumping in full speed to catch up to them. After passing a few corridors, they gone inside the cabinet room just to see the trio on the other side of the doors.

Then the Doctor bluffed his way through with the decanter, making them believe that he would blew them all up if they made another step. Though the bluff won't stay a bluff for long. After a few questions, one of the Slitheens seemed to caught on.

"Aaaaahhh, Excuse me? Your device will do what? Triplicate the flammability?" he asked sceptically.

"Is that what I said?" the Doctor said while biting his lower lip.

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

"Oh well, nice try. Harriet." The Doctor offered Harriet Jones the decanter. "Have a drink. I think you're gonna need it."

"You pass it to the left first," Harriet said, not breaking eye contact with the aliens ahead.

"Sorry." The Doctor handed it to Rose, but she refused to take it and with a laugh gave it back to Harriet.

"No, it's alright. You can keep it." She grinned at the woman. It made the Doctor and Harriet look at her in bewilderment.

"What?" Rose just asked innocently.

"Better pass it to the left," the Doctor said while getting his gaze back at Slitheen.

"To the left." Harriet slowly gave Rose the decanter back, not meeting her eyes. Rose just looked at her hands, now occupied once again and frowned. They think I have gone mad already.

The Doctor tried to look tough for a moment, not showing any sign of fear while facing the aliens, while they, on the other hand, were sharpening their claws.

"Fascinating history, Downing Street..." The Doctor began to show off his unlimited knowledge. "If the Cabinet was in session, and in danger, these were about the four safest walls in the whole of Great Britain. End of Lesson." He hit a switch, activating the steel safety doors.

"Installed in 1991, 3 inches of steel lining every single wall. They'll never get in," the Doctor exclaimed proudly, to which Rose just rolled her eyes.

"Great!" Rose beamed at him mockingly. "But how do we get out?"

The Doctor looked around and nodded. "Ah."

Inside the Cabinet room, the Doctor pulled the unnamed man inside the cabin. "Sorry," the Doctor said, looking at him. Seconds later, he was going about the room, trying to find the signal to get out. It's never going to work. Rose took her surroundings as she knew it would be the last place she was in of the Downing Street. Now, only the rocket will get us out.

The Doctor told her about the Slitheen having an ability to compress themselves to become a bit smaller for fitting into human bodies. "Oh, it could come in handy if I had such an ability," Rose said jokingly, he just grinned.

"Excuse me, people are dead. This is no time for making jokes," Harriet scolded them.

"Sorry," Rose said in a voice which didn't sound sorry at all. "You get used to this stuff, when you stay friends long enough with him." Rose pointed towards the Doctor.

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

While the Doctor tried to find reason how did he knew Harriet Jones, the future Prime Minister was complaining about not getting any use of the emergency protocols, since all of the needed people were downstairs - dead.

"We could just launch a missile at them." Rose shrugged. Harriet looked at her in astonishment and horror.

"You are very violent, young woman."

"I'm serious, we could," Rose said simply.

The Doctor and Harriet were having a small conversation when Rose's phone buzzed. "How do you get a signal here?" the woman asked in disbelief.

"Oh, he's got a super phone," Rose said teasingly.

A picture of Slitheen was seen on the phone. Rose could feel her blood drain. Her mum! She forgot about the Slitheen at Mickey's. How could she had done that? She was already panicking when the Doctor asked her. "What is it?" With a gulp Rose answered. "It's Mickey." Her forehead wrinkled.

"Oh, tell your stupid boyfriend, we are busy." He shot a look of annoyance. Rose glared at him in hurt, though he was not the one at fault.

"He's not stupid. Look!" She showed him the picture. Moments later they were on the phone.

"Is that Rickey? Don't talk. Just shut up and go to your computer," the Doctor instructed.

"It's Mickey. And why should I?" Mickey's voice could be heard from the other side of the phone.

"Rickey the idiot. I might just choke up before I finish this sentence but...ah... I need you," he finished forcefully. Rose grinned at that.

Mickey was hacking into the UNIT's database, Harriet was pacing the room while Jackie was talking from the speaker. "I have seen this life of your's, Doctor. And maybe you get up for it. And maybe you think it's all clever and smart. But, you, tell me. Just answer me this." Rose closed her eyes, knowing what was coming.

"Is my daughter safe?"

"I'm going be just fine, mum," Rose told her mum through the speaker.

"Is she safe?" Jackie repeated. "Will she always be safe?"

Rose took a deep breath.

"I won't be, without him, mum," Rose said softly. The Doctor looked up at her in confusion. Rose gave him a small smile. "I'll see you at home, alright?" She spoke to the speaker again.

A pause.

"We are in." Mickey's voice echoed in the room. The Doctor instructed Mickey about the site when a door bell buzzed.

Thump.

"Mum, don't answer the doors!" Rose warned her.

"It's Mickey here. And she's already left to open them."

"Get her out of there!" Rose shouted, making the occupants of the Cabinet room jump in surprise. "It could be the Slitheen!"

"Oh, my god," Mickey said. "We forgot about him. Jackie?" he called out.

Rose was looking frantically at the phone. The Doctor seeing her state, placed his one hand on her shoulder. He locked his gaze with hers, trying to convey what words couldn't. Rose just nodded simply.

"They found us," Mickey stated.

Rose could feel her legs become numb. "We need that signal," the Doctor said. Rose gave him a warning look. "Never mind the signal, mum, just get out!"

"We can't. He is at the front door."

"Then defend yourselves!" Rose said in desperation.

Harriet was talking in frustration at the Doctor. "You are supposed to be the expert, think of something!"

"I'm trying!" the Doctor cried.

Rose closed her eyes and clenched her fists. She can't interfere. She can't. But she was loosing it.

"I'll take him on, Jackie. You just run." A voice came from the speaker.

That's it.

"If we want to find their weakness we need to find where they are from," Rose stated in monotone voice.

"Right," the Doctor agreed. "So judging by their body shape that narrows it down to about 5,000 planets in travelling distance. Now what else do we know? Information!" he urged them.

"They are green." Rose said.

"Yep, Narrows it down." The Doctor nodded.

"Good sense of smell," Rose said still in monotone.

"Narrows it down."

Rose was losing her patience. The next time he says narrows it down she is gonna show him just how she will narrow him down.

"They can smell adrenaline." Either Harriet or Rose said. She was not sure as her head was thumping.

"Narrows it down."

Snap. Rose could hear herself snap inside.

"The pig technology," Harriet said.

"Narrows it down."

"The spaceship in the Thames; you said slipstream engine," Rose breathed.

"Narrows it down."

"It's getting in!" Mickey's voice announced.

"They hunt like it's a ritual."

"Narrows it down."

"Wait a minute. Did you notice?-" Harriet began.

And before anyone could continued, Rose interrupted in a rushed voice "When they fart, it doesn't just smell like a fart, it's more like bad breath," Rose said blankly.

"That's it!" Harried exclaimed.

"Calcium decay. Now that Narrows it down!" The Doctor beamed.

"We're getting there, Mum!" Rose tried to assure her family.

"Too late!" Mickey yelled back.

"Calcium phosphate. Organic calcium. Living calcium. Creatures made out of living calcium. What else - what else? Hyphenated surnames. Yes! That narrows it down to one planet! Raxacoricofallapatorius!" the Doctor announced.

"Acid. Vinegar!" he was shouting in the speaker.

"We got that!" Jackie said in relief.

"You do?" Rose asked in disbelief.

"What, do you think I didn't go shopping just because I'm at Mickey's flat?" Jackie mocked.

"Great. If you did, great, mum," Rose breathed in relief. "Now, pour it on the Slitheen once it reaches you." She instructed, making Doctor turn to face her.

"How did you know that?" he asked her.

"What else you gonna do with it?" She grimaced at him.

And soon a farting explosion sound could be heard. Everyone exhaled a sigh of relief. "Here you go, then." Rose picked her glass of wine in a toast, grinning.

"Our race will face extinction. Unless we strike first." The newly appointed Prime Minister's Slitheen voice could be heard on the telly. "I beg the UNIT. Give us the codes to the nuclear weapons." He faked a concerned face. "Because from this moment on...it's my..duty, to inform you. Planet Earth is at war," he ended with a strong impact on the word.

Then the Doctor, Harriet and Rose were back to arguing with the Slitheen about the missile. "I give you a choice. Leave this planet or I'll stop you." The Doctor's voice cold. At that, the aliens just giggled.

"What, you?" Blon mocked him. "Trapped in a box?"

"Yeh," the Doctor simply said. "Me." And pressed the button to separate them from the alien threat.

"Okay, Doctor. I'm not saying I trust you, but there must be something you could do." Jackie was speaking on the phone, when everyone learnt from the News that the massive destruction weapons did exist.

"There is a way out." The Doctor's voice faint. Rose looked up at him. "There was always a way out."

"Okay. Then we use it," Rose said simply.

"But I can't guarantee your daughter will be safe." The Doctor walked to the speaker.

"Don't you dare. Whatever it is. Don't you dare," Jackie warned him.

"That's the thing. If I don't dare, everyone dies," the Doctor said, his voice wavering.

"Do it," Rose said simply.

"You don't even know what it is. You'd just let me?" The Doctor looked at her in bewilderment. How could she trust him so much?

"Yeah." Rose smiled at him fondly. She could remember the first time he had to make this same decision. She had already had full trust in him back then. And it never changed. She wouldn't toss her life pointlessly, but if she was needed by the Doctor, she would always be by his side.

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

"Do you think I don't know that? 'Cause this is my life, Jackie - it's not fun, it's not smart, it's just standing up and making a decision because nobody else will." His voice cracked a bit.

"Then what are you waiting for?" Rose locked her eyes with his. She hated to make him chose, so she wanted him to know, that it was her choice. "I've made my choice. I'm staying with you no matter what." Her eyes didn't waver.

It scared him. He was scared to lose her. Since the moment the two of them met, she always followed him around recklessly, and made it certain to ensure her presence never leaving his side. Whereas now, it could be all lost in seconds. "I could save the world, but lose you." Words escaped his mouth in a voice full of devastation.

"Except it's not your decision, Doctor." Harriet came forward. "It's mine."

"And who the hell are you?" Jackie spat in disgust.

"Harriet Jones. MP for Flaydel North. The only elective representer of this room. Chosen by the people. For the people. And on the behalf of the people, I command you. Do it."

When the Doctor looked back at Rose, he found her grinning widely at him and he grinned back.

"How do we get out, Doctor?" Harriet asked.

"We don't. We stay here," Rose said simply.

"You knew?" the Doctor asked her in astonishment.

"I read between the lines." She gave him a small smile.

After picking the correct missile everyone waited in anxiety. "Rickey the idiot. The World is in your hands," the Doctor announced.

"Fire."

"How solid are these?" Harriet was asking about the steel doors.

"Not solid enough. Build for short range attack. Nothing this big," the Doctor told her, not sure about the escape plan himself.

Rose made her way to the cabin. "Alright. Now, it's my time to make a decision. We are not going to die. We'are going to survive," she exclaimed. "This is small. Solid enough." She checked the cabin. "Both of you, inside," she ordered and the trio sat inside.

"Nice meeting both of you," Harriet said. "You too," the Doctor agreed then looked at Rose.

"I'm so glad I've met you." He smiled at her warmly.

"It was the best thing in my life," Rose said with a tender smile. And the three of them linked their hands tightly, waiting for the destruction to reach them.

Then something hard hit them. The whole place shaking horribly. The cabin rocked hard. Rose wondered if it was that bad the last time. Then it started to roll, throwing its passengers around. Rose could feel how she crashed onto the Doctor at one moment, since he put his protective arms around her.

And with the last thud they stopped.

Creak.

The Doctor kicked the doors out and the three of them stepped outside. Harriet Jones didn't waste time and soon left to attend her "responsibilities". The Doctor just beamed at her. "I thought I knew the name. Harriet Jones. Future Prime Minister."

"She is a great woman," Rose added in agreement. The Doctor looked back at her. "You alright, though?"

"Yeh," she told him fondly. "And we got one more rescue to do." She pointed at him.

"Right," he agreed.

The TARDIS landed in the same storage room they had been the day before. Once they opened the door, Rose sighed in relief. "No military officers here." She grinned.

"Everyone has gathered outside the 10 Downing Street. Or now, outside the pile of rocks and dust." He gave her an innocent look.

"I can't believe that we've actually blown Her Majesty's government headquarters up." She shook her head, chuckling. They started going down the hallways. "And I so wanted to go there at least once." Rose spoke in nostalgia.

"Well you did. And now hush," he warned her.

They listened for any signs of the disturbance, but there was none. The halls were empty so they managed to run towards the holding cell unnoticed.

The doors were locked, however, the Doctor quickly opened them with his sonic screwdriver. Once they made their way inside, they saw nothing. It was pitch black.

"Can't you turn the lights on?" Rose asked him.

"It's not working," he answered.

"Not that kind of light. Use your sonic screwdriver!"

"How do you know it makes a light?"

"Oh, for goodness sake. With hundreds of actions it can perform, you would just leave the lights out." She mocked him.

"Makes sense," he agreed as he made the screwdriver glow. It was still quite dark.

"Um." The Doctor frowned at that. Not like anybody saw that, though.

"Maybe you could move the TARDIS here then, yeh? It would emit the light, better than this. I see no-" She began but cut herself sort when her foot met something hard. She winced in pain. "-thing," she choked through her teeth.

"Alright. You stay here," he told her and was about to move, but kicked the same thing Rose had just moments ago and it made him stagger. In the end he fell on something.

"Uff. Really, better get the lights here." His sonic screwdriver could be seen somewhere in the distant. "Something soft here."

"That would be me," Rose told him from underneath.

If anyone could have seen the Doctor's face now, it would be a great show to watch, but now only a gulping sound was heard. "Sorry. You alright? Didn't break you or anything?" He tried to sound nonchalant as he stood up, pulling her up on her feet moments later.

"Nah. It needs better than that," she joked. "Now, go on," she urged him and he soon left the room, grabbing the sonic screwdriver just before.

Thump.

Okay. That surprised her. She shook her head. No time for this.

Rose looked around the room. And well, saw nothing. So she walked her way forward, putting her hands ahead of her. She came to a stop, when she felt cold metal bars and a warm even breath on her fingers.

"Hello there." She greeted the living thing lovingly.

"Oink." It made a sound.

"We've found you!" she exclaimed happily, but lowering her voice at the end. Seconds later the TARDIS materialised into the room, illuminating it and showing the occupant of the cell.

With doors opened the Doctor stepped out. "Right, then." He came forward and with a few buzzes let the Space Pig free. "Hurry up, come on," he told Rose and the pig as they followed him inside the TARDIS.

Inside the console room the Doctor gave Rose the directions of the temporal room their new companion would be staying at and after pressing the necessary buttons, he directed them to the Powell Estate.

After the emotional reunion with Jackie, Rose found herself sitting in the living room, watching Harriet on the telly.

"Harriet Jones. Who does she think she is?" Jackie complained to the telly. "Taking all the credit. My daughter saved the world." She leaned in to it.

"Thank the Doctor." Rose smiled. "He's not that bad, if you give him the chance." Rose grinned at her mother.

"Alright. I give him that," Jackie said, unhappy to admit.

"Oh my. The world does change. You actually approve of him." Her grin was wide now.

"Nothing else I can do. Since you are infatuated with him." Jackie looked back at the telly.

"I'm not infatuated with him, mum. I love him," Rose said with a fondly smile. She felt her mother's gaze and looked around. It took her a moment to catch on just what had she said.

"Erm... Um," she shuttered. "What I meant to say was..."

"Oh, save it." Jackie just dismissed her. "What does he eat?"

Rose blinked a bit in a surprise of the next topic being dropped at her so soon. "He won't eat with us. But I could bring the tea to him. He just might accept it."

After Jackie went inside the kitchen to prepare her tea, Rose's phone rung with "TARDIS" calling.

"Hello?" Rose answered softly.

"Right. It's going be a couple of hours, before we could go." The Doctor's voice echoed from the other end of the line.

"Do you want shepherd's pie?" she asked simply.

"What? Where would you get that?" he asked, slightly confused.

"My mum's cooking."

"Great. Then enjoy yourselves," he said dismissively.

"I was asking about you," Rose persisted.

"I don't do that," the Doctor dismissed her at once.

"I know," she said in a faint voice.

Pause.

"I'll have to go meet Mickey, then I'll come back. Don't disappear on me." She chuckled on the phone.

"Okay."

"You sure you don't want the pie?" she asked him teasingly.

"See ya." And the Doctor hang up.

The talk with Mickey went a bit worse than Rose originally thought. When they broke up the last time, he already understood the situation quite well, from observing. But at this moment, he still held a lot of hope. It hurt her to disappoint him so much. And she wanted to keep in touch with him. Luckily enough, he offered to send her off.

Once they reached the TARDIS, Rose saw some kid kneeling on the ground and scrubbing the graffiti words off the TARDIS side.

What were the words again?

Right.

Of course.

Bad Wolf stood tall, together with the Earth. Once again.

The Doctor and Mickey were having a conversation about "Alien hoax", which the news had created, being not yet ready to face aliens. Rose felt a stab in her heart. Those same people were going to learn the truth about aliens the hard way. She feared for that day to come.

Then she looked back at the Doctor and her worries seemed to cease to exist for that moment. She grinned at him as she walked towards and pulled her backpack off her shoulders.

"The first time I stepped in, It was the spur of a moment. Now, I'm singing in." Or re-signing. "You are stuck with me." Rose pointed at him, smiling with tongue between her teeth. The Doctor seemed to be taken aback by surprise, but not an unwelcome one.

With a few goodbye words they stepped inside the TARDIS, closing from the world outside those doors.

Once inside, Rose rushed to the room to where their new friend was now staying. She found him moving about, sniffing everything - still a bit lost of his surroundings. When he saw Rose, he moved towards her.

"Hello." Rose greeted the piggy.

She seemed to use that word a lot these days. Too much influence of her Doctor, she guessed, as she chuckled sadly. She missed him. The him him, who knew everything about her. Who knew her as she first came in contact with him and who burnt the sun just to say goodbye to her. Her heart tightened.

It was just not fair. She wanted to tell him everything. And she hated the knowledge she had. Not only the moments of their adventures, but that she knew better now than to disturb their timelines by telling the Doctor the truth. Which was who knows what truth, still.

Sigh. She sighed out loud and the piggy moved his head to the side in a question. It made Rose chuckle. "Oh, you adorable little thing." She patted him.

She was too immersed in playing with their newly made friend that she didn't notice how the Doctor came halfway inside the room. Just watching her from the doorways.

While watching Rose, the Doctor couldn't believe what he was seeing. How compassionate she was. Rose was the first known human to him who cared so much about aliens. And he was even more amazed just how it suited her. How right the picture in front of him looked. The Doctor still had a few questions of his own about Rose, as she seemed to have some kind of secret around her. Besides the times when she looked too much excited and fantastic, he could see a deep sorrow in her eyes. He recognised it, because it was so very close to his own. And what puzzled him even more, was that it looked like even Jackie and Mickey were not aware of any of it.

But he decided to take one step at a time. To let her keep her thoughts to herself. If there was anyone to be complained about being too much shut off, then it would be him. They will get to know each other as time passes by. For now, this was good enough.

to be continued..

A/N: okay then. Any kind of feedback would be great! I'm not exactly sure what I think about this chapter. At first, I was greatly disappointed, since I couldn't really change many of things. I couldn't leave Harriet alone and Rose's actions in the long run doesn't really change all that much then...but I tried my best. Anyway, it is yours to judge, feel free.

About Rose's remark - the Doctor not being him him. That just came out with my belief. As I believe memories make the person. Or at least is a very big part of it.

And that's about it. Wait for more. =)
