The TARDIS flew through the time vortex at a light speed as Rose positioned herself on the jump seat beside her previous self. She was lost in thought, eyes closed with her head in hands. Rose patted her on the back soothingly as her previous self raised her head and turned towards her. They both sat in a comfortable silence, watching as The Doctor manoeuvred around the console, flick switches and pressing buttons in a confident manner. He seemed to be back to his regular self which was good news, but Rose knew it wouldn't last for long. Her previous self yawned and stretched, obviously exhausted. It had been a very long day and it was about to get much longer. She too, was exhausted, especially after her recent regeneration that she had barely begun to comprehend, but she was currently running on adrenaline, not wanting to stop. Because stopping meant thinking. And she really didn't feel like thinking right now. The familiar sound of the TARDIS braking filled her ears as they rematerialised at the Powell Estate. Home. Rose thought, a warm feeling Rose through her but it was tinged with sadness. It was growing inevitably closer to the day she would never see her mum again and Rose wasn't sure that she was ready to face it again.

It was, however, a welcome relief to be landing the TARDIS rather than plummeting to earth. Right, Rose thought, pushing the melancholy thoughts out of her mind, This should be easy. Just stay out of trouble and let things go as they should. But of course, it was never that easy.

"Here we are then, London. Earth. The Solar System." The Doctor announced with a grin, rubbing his hands together. Her previous self jumped up and headed towards the door, eager to see her mum and Mickey again. Rose trailed behind her a little more apprehensively, but as she reached the door, she felt a tug on her arm pulling her back. "We'll be out in a moment Rose!" The Doctor called, stepping around her to close the TARDIS doors with a thud. He crossed his arms and leaned casually on the TARDIS doors, blocking her way out. "So…" he began, staring at her intensely, "How did know how to fly the TARDIS?" Ah… Rose thought, He's interrogating me. Of course, after I told him not to. He never listens. Well two can play at that game. Rose crossed her arms and stared back at him, mimicking his expression. "Wouldn't you like to know."

"Yes I would. That's why I am asking you." He replied matter-of-factly, his intense gaze searching her own.

"Well I guess today's not your lucky day then, because I'm not saying anything." She spoke boldly, arms still crossed over her chest.

"Of course you aren't." He muttered to himself, dropping his gaze for a moment before growing frustrated, "Just tell me. Future girl."

"I can't."

"Why?"

"You know why."

"Yes. But I hate not knowing everything."

"I know." A smile growing on her lips. It was nice to actually know more then him for once. He was far too arrogant and definitely needed taking down a few pegs. The Doctor sighed, clearly defeated but not wanting to admit it. Rose cheered a silent victory but gave him a warm smile, knowing how frustrated he must be. "I'm sorry Doctor but you just can't know yet. But you don't want a future without me do you?" She added playfully, grinning at him.

"Oh I don't know… it wouldn't be so bad…" A smile forming on his lips. Rose reached forward and hit him lightly on the shoulder with a mock scowl on her face. "Oi!" He yelped, rubbing his shoulder and straightening himself up.

"That was nothing Doctor. Just wait and see what the future has in store for for you."

"You've met Jackie Tyler I presume?" He asked questioningly, still rubbing at his shoulder.

"Of course."

"Then please tell me. Does she ever warm up to me? Because last time I was here she nearly slapped me into my next regeneration." Rose just laughed and rolled her eyes. Pushing open the TARDIS doors, she grabbed the hesitant man by the arm and pulled him out the door.

The familiar sight of the Powell Estate greeted her as she stepped out the TARDIS doors, dragging The Doctor along with her. Satisfied that The Doctor would stay put, she let go of his arms and began to take in her surroundings. Her previous self was unsurprisingly in a heated argument with her mum whilst Mickey stood a little further back from her, not wanting to get involved. She didn't blame him. Stepping in between one of their fights was like stepping into a lion's den. It didn't end well. Noticing their presence, the argument abruptly stopped as her previous self, Jackie and Mickey turned towards them. "Jackie. Mickey. Blimey!" The Doctor began to circle around them and grabbed onto their shoulders as their mouths opened in shock, not recognising him. Rose watched in amusement as he babbled, trying to cope with his nervousness. "No, no, no, no, hold on. Wait there. I've got something to say. There was something I had to tell you, something important. What was it? No, hold on, hold on. Hold on, shush, shush, shush, shush. Oh, I know! Merry Christmas!" He grinned before promptly passing out. Mickey gently lowered him to the ground as both Rose and her previous self stepped forward to help. "Is he alright?" Her previous self questioned worriedly as she looked down at him. Rose looked down at his sleeping self. He looked so… peaceful, something that you never saw is his normally animated, waking form. "I don't know. But who is he? Where's the Doctor? And who are you?" Mickey turned to face her but before Rose could reply her previous self interrupted them.

"That's him, right in front of you. That's the Doctor."

"What do you mean, that's the Doctor? Doctor who?" Jackie questioned in surprise, not quite believing what she just heard.

Rose grinned, enjoy this immensely. She had missed this and was going to savour every moment of it. "That's what I was trying to explain to you before. He regenerated." Her previous self replied.

"He what?"

'He regenerated."

"He what?" Jackie still looked very confused, switching her gaze between her and The Doctor.

"Oh never mind. It's still him okay. He just looks different." Rose decided to interrupt them, knowing that they should get him inside soon. It was dangerous for him to be out in the open. It drew far too much attention. "We need to get him inside. He needs rest. And it's not exactly safe out here." Her previous self nodded, glancing at her up and down. "Hey Penelope. I'm your friend right?"

"The best. Why?"

"Well as your best friend I have to tell you that you look like a bloody mess." Rose glanced down at herself, noticing that her clothes were basically in tatters and she did not even want to think what her hair looked like.

"You're right. I look awful." Rose replied with a laugh gesturing towards the TARDIS, "I'd better go clean myself up."

"Will he… will he be okay?" Her previous self asked quietly.

"He'll be absolutely fine." She reassured. "Just get him upstairs and maybe change him into something more comfortable. I'm sure you'll enjoy that." Rose winked and watched as her previous self began to blush before gaining control of herself.

"I don't… I don't know what you're talking about."

"Of course you do. Now as much as I'd like to stay for the show, I'd better go. I'll meet you upstairs." My god. Rose thought as she turned towards the TARDIS, "When did I become so over confident? I'm turning into The Doctor." Rose shuddered at the thought. She may love The Doctor but she definitely didn't want to become him. One Doctor was definitely enough. Making a silent plea to herself to change her ways, she walked towards the TARDIS before pausing at the door. "My name's Penelope Smith by the way. Nice to meet you." She called to Jackie and Mickey, before unlocking the door with the key around her neck and stepping inside.

Feeling the welcoming hum of the TARDIS as she made her way inside, Rose almost collapsed in exhaustion as she slid down the doors of the TARDIS, landing on the floor with a bump. The regeneration had taken a lot out of her, even though she could tell that the TARDIS had been shielding her from the full force of it. Hey TARDIS. Rose thought, would it be possible-

Yes, I can give you more energy but it won't last for long. The TARDIS hummed in her mind, interrupting her question.

How long? Long enough to-

Long enough to save the earth, yes. The TARDIS interrupted again.

How do you-

How do I do that? I'm in your head my wolf, I see all your thoughts before you even project them.

Oh. Well I suppose that makes sense. Definitely not the most unusual thing I've ever experienced. Could you please-

Call you Rose? If you wish, I understand that you don't exactly feel comfortable with the Bad Wolf title.

It's not that I feel uncomfortable I just-

Don't feel like you deserve a title? Well I think you do. You are a remarkable person Rose and you will do so many amazing things. But until you feel that way, I'll use Rose for now.

Thank you. I just have-

So many questions? I know Rose and they will all be answered in time.

But what exactly am-

What exactly are- Rose had had enough of the TARDIS interruptions and was beginning to feel frustrated. It was almost impossible to even get a word out before the TARDIS finished her thoughts. Would you just let me finish! Rose yelled in her mind and she felt the TARDIS shudder in surprise.

Very well.

Thanks. Sorry for shouting at you. Anyway, what I wanted to ask was what exactly am I? I know I'm part human and part time lord but what does this entail exactly? What can I do?

Well, as I said before you can obviously regenerate and have telepathic abilities but as for any other abilities… that is still unclear. I'm sure they will make themselves known in time, if there are any.

Right… Rose sighed, So my mind is still the same right?

Well… The TARDIS began, knowing that her mind with a touchy subject. She strongly disliked anyone messing about with her mind, it is essentially the same, just slightly modified.

What do you mean? Rose demanded.

It had to be developed slightly to allow you to be telepathic of course, however, nothing drastic has changed, you still have the same memories and intelligence. You are still you. Although, as you've noticed, your personality, appearance and voice have changed slightly.

Rose nodded slowly, processing this. She was surprised how well she was comprehending this. I guess all that time with The Doctor prepared myself for this. I've really seen it all. Rose thought to herself. Alright, I'm ready for that energy.

The TARDIS hummed as she felt a rush of energy pour through her body as the exhaustion faded away and energy filled her body.

"Wow," Rose breathed, "I feel great. Thanks TARDIS."

Your welcome. She felt the TARDIS's presence fade to the back of her mind.

Right. Rose thought, Time for a shower.

Rose stood in the TARDIS wardrobe room in front of a mirror, her eyes squeezed shut. Her damp hair clung to her skin as she shifted her weight from foot to foot nervously, a towel wrapped around her. It was time to see what she really looked like. She had not even peaked when she went for a shower, keeping her eyes closed through its entirety. She didn't know why she was nervous, after all, there was nothing she could really do about it but she still felt uneasy. She knew that the second she looked she would be letting go of her previous self and welcoming the new. Rose Tyler 2.0 she thought with a small smile. Sighing, she clenched her fists and mustered up any bit of courage she could find. Okay Rose. In three, two, one… She breathed in slowly and opened her eyes. A complete stranger was staring back at her. Tall and slender, with light brown shoulder length hair sun kissed with a few blonde highlights. My natural hair colour. Rose thought, Haven't seen that in a while. She did have to admit that her previous bleached blonde hair done by her mother was not exactly a good look. As she glanced up again, she noticed that her eyes with hazel, an almost golden colour. Fitting, she supposed. Examining herself closer, she noticed that a few freckles danced across her nose and spilled out onto her cheeks. Moving away from her face, she turned around and examined herself a little longer, taking it in. She did not look terrible, in fact she had to admit she looked quite amazing considering the stories The Doctor had told her about regenerations. It will take some getting used to, Rose thought supposedly, but I think I'll quite enjoy this new me. She grinned in the mirror, her eyes sparkling. Now. Rose thought, now for some clothes. Rose wandered around the TARDIS wardrobe room, trying to find something she liked. Her tastes had certainly changed since she regenerated and she definitely did not like pink so much anymore. Finally deciding on pair of black skinny jeans, a white t-shirt, a red flannel shirt to be worn as a jacket, a dark green coat with a hood and a pair of black Converse high tops, she stared at herself in the mirror, nodding with approval. Straightening her hair and putting on a bit of light make up, she headed to the door but paused for a moment, grabbing a pair of sunglasses and slipping them into her coat jacket before making her way to the console room.

She found her previous self waiting in the console room, arms folded. She smiled at her when she walked in the room. "You look fantastic!"

"You think so? I wasn't sure…"

"Oh definitely. It might not be exactly my style but I like it on you."

They both smiled at each other before Rose asked, "How's The Doctor?"

"Alright I think. Both his hearts are still beating. Mum wanted to take him to the hospital but I didn't think we should."

"Yeah that's probably best. They'd treat him like a lab rat." Rose replied with a nod. 'So what brings you down to the console room?"

"I was just wandering if you wanted to come out to the shops with Mickey and I? It's been a little weird between us lately so I'd rather have someone with me." Rose sighed, knowing exactly what she meant. She knew she didn't love him anymore but couldn't exactly comprehend it or admit it.

"Sure I'd love to. But can I give you a bit of advice?"

"Of course you can. You don't even have to ask."

"Don't string Mickey along if you don't love him anymore. It's not fair to him or you." Her previous self was silent for a moment before nodding.

"You're right. I just couldn't bring myself to admit it. I'll tell him before we leave." Rose felt huge weight lifted off her chest. That had definitely been one of her regrets, that she had never ended things properly.

"So you've decided to come back?"

"Yeah." Her previous self nodded, "I couldn't miss it."

"Me neither."

Rose, Mickey and her previous self walked along the streets of London taking in the Christmas scenery. As they walked past the brass band in Santa costumes, Rose kept a sharp eye on them, not letting them out of her sight. She breathed deeply, knowing that she couldn't stop was about to happen. She quietly listened in on Rose's and Mickey's conversation. "So what do you need? Twenty quid?" Mickey asked, manoeuvring around a couple as they walked down the crowded path.

"Do you mind? I'll pay you back."

"Call it a Christmas present."

"What about you?" Mickey turned towards her, "You need any money?"

"No I'm alright thanks. I don't really have anyone to buy for anyway." Rose replied, feeling a tightness in her chest. She tried to shake off the feeling with no avail.

"So what are to The Doctor? One of his women? How many of you are there? Do you take it in turns or something?" Mickey questioned.

"Mickey!" Her previous self shouted, "That's so rude. You know he's not like that."

"Do I? Because I really don't know him at all." Rose stayed silent, not wanting to jump into that conversation. The pair continued to argue about the TARDIS and The Doctor before they reached the market

"Right! What're you going to get for your mum?" Mickey asked as they walked around the market. Rose could see the brass band out of the corner of her eye, following them. She tensed and her previous self noticed, abruptly stopping. "What is it? What's wrong?"

"Keep moving. Don't stop. But do you see the brass band behind us? The one's in the Santa costumes?"

"Yeah." Her previous self replied as they continued walking, turning her head slightly to look behind them.

"They're following us."

"What? Why?" Mickey asked, stopping to look behind them. Rose grabbed his arm and pulled him along.

"Why do you think? They're after The Doctor so what do they do? They come after us. The one's closest to him. Eliminate us and The Doctor is theirs."

"So what do we do?" Her previous self asked nervously.

"We run." Rose replied as she grabbed both of their hands and ran as flames flew behind them.

And that's it for chapter 4! I hope you enjoyed the episode. This one was a little bit Rose based and slightly domestic but I promise the next chapter will have a lot more action. Anyway, I'm aiming to have the next chapter out by the 5th of March or earlier, however, I have a lot of assignments at the moment so it could possibly be later. Goodbye for now!
