Part One

"I looked into the TARDIS and the TARDIS looked into me."

"I am the Bad Wolf. I create myself. "

...

"I want you safe, my Doctor."

Those were firm words, spoken with the trembling voices of a young desperate woman and an ancient time traveler. Two females in love with the Doctor, changed the status quo. Two beings that would do anything to keep the one person – they both unconditionally and irrevocably loved – safe. Forever.

Rose Marion Tyler and the TARDIS merged into one infinite creature. The Bad Wolf. A being that should not be and that was too powerful and dangerous to ever exist in a way like this.

Of course, the Doctor released Rose Tyler of the entire Time Vortex that had been trapped in her head and let her be a mere human once again, but the connection between the TARDIS and Rose Tyler had been created and nobody would ever be able to separate them ever again. The TARDIS would not let her go. They became sister when the two of them looked into each other's hearts.

The Doctor put the Bad Wolf to sleep, but bits and shreds lived on within Rose Tyler, waiting patiently for the time she'd need the Bad Wolf once again. The TARDIS and Rose Tyler had promised to keep the Doctor safe. At any cost and they intended to keep their promise, no matter what might happen to them in the future. The two of them had made sure – in this little moment – the Doctor would be safe until a certain point in time.

The first time she was left alone on Dårlig Ulv Stranden it shattered her heart into pieces. Okay, she wasn't alone. Her Mum was there, but still. Never again had she felt that alone. When the Doctor dropped her off there for a second time, she simply could not believe it. How could he leave her there, on the very same shore, with a clone looking exactly like him, but oh so different at the same time? The Doctor punished Rose and himself with this act. Of course he was right and could not let the meta crisis remain in the same universe he lived in. And of course he wanted to have Rose her happily ever after. The one thing he himself could not have with her. But it still hurt so much. Even if the meta crisis told her he loved her. Even if they'd shared this one kiss, the Doctor was never able to give Rose. Even if Donna Noble left them a piece of the TARDIS. Still. The Doctor had left her behind once again and it had broken her heart. Again.

Everything that happened shortly after their separation was like a blur for Rose. The meta crisis, Johnathan Noble he liked to be called, tried to cheer her up and engage her in a romantic relationship. Her mother told her she could now have a family of her own and should forget the old daft alien, but how could she forget the man she desperately loved?

It took weeks until Rose was able to move on at least a little bit. It took months for her to stop trying to get back. It took years for her to realize that John and she could not have children together, ever.

After all, Rose and John loved each other and grew old together. Even without children they had one baby that kept them sane. They'd grown their own TARDIS and traveled this alternate universe until the very end.

As Rose and her John saw the end coming, they decided to spend the rest of their time with Rose's brother's family. It was a warm and sunny day in spring, when the old and withered Johnathan Noble passed away, leaving his Rose behind once more. This time she did not despair, because old and white haired Rose knew that her time was soon over as well. She felt it coming, one day, only weeks since John's funeral.

Rose sat in the garden of her family's estate watching the stars above her, when she felt her heart weakening. Smiling she leaned back and closed her eyes. Thanking the multiverse for the fantastic life she had, for all the drama and tragedy. For all the loss and all the love. Rose's life hadn't been easy or perfect. But it was a good life, full of adventure and two mad men with blue boxes.

Tony stood at his rooms' window and kept his eyes on his elder sister. After her husband's death she had given up every will to live. Of course, she was still this beautiful and sassy woman he came to admire in young years, but there was no reason for her to stick around any longer. It hurt Tony that she would leave him behind like that, but that was life and he still had a family of his own, so he should not complain. He decided to watch her as long as he still could. At least she had agreed to stay at the manor until… well, until it was over.

Rose was sitting at this little parlor in the garden, watching her precious stars. She had visited them all in her limited life span; Tony had visited a few with her and John. All seemed pretty normal until he saw a light emerging from Rose. A golden glow started to shimmer around her fingers until she suddenly shot up from her seat and the light burst out of her arms, feet and head. He was frozen on his spot and could do no more than watch her burn. At least it looked as if she'd burn until it stopped as sudden as it had started. His sister fell to the ground and sat there on her knees.

What Tony saw in front of his eyes could not be true. His sisters white hair was golden blonde again, a little bit of the color she always had dyed it, but much more natural. Rose slowly got up from the ground and turned her head into his direction, before she collapsed to the ground. At this moment Tony snapped out of his shock and rushed out into the gardens.

Rose could not believe it. A golden gleam suddenly surrounded her and she knew what this meant, but still couldn't wrap her mind around it. A heat rose within her and cast out the cold of her body she had felt since John had passed away. She was dreaming this. She had to! There was no way this could possibly be happening. She was supposed to die, not to live on in a world without John or the Doctor. She was definitely not supposed to regenerate and she did not want to live in a world without the Doctor. Where was he when she needed him most? Was he still this handsome English bloke, or had he regenerated? She'd rather die than be trapped in this false universe alone for eternity.

When the regeneration stopped she fell down on her knees and looked at her hands. Rose felt her mind expanding and needed a few seconds during the process to notice all changes. A few seconds ago her fingers and hands had been deeply wrinkled with a few age spots. Now she looked at a young, flawless hand. She definitely needed a thorough manicure… Fast she got up and looked at the manor. Her head started to spin; she had jumped up too fast and she could feel the earth moving around her. The last thing Rose saw, was her brother looking down at her from his rooms window and then everything went black.

After a few days, Rose had fully regenerated and looked like her twenty year old self. Once she had some of tea and a good day's sleep she literally felt like a new person. She wondered why she still looked like herself and not like some random stranger, but she was glad she got to keep her looks. Tony insisted on a few tests and had a Torchwood doctor come over to check her through. She was completely fine and healthy as a twenty year old should be, but there was more. Rose had two hearts now. Someone had given her a Gallifreyan upgrade as it seemed. When she was ready to wander off again, she hid in her TARDIS and sought out some answers.

"I do not know what happened, but I hope you can help me, little one." She said and stroked her TARDIS' door. It looked exactly like her Doctors TARDIS, simply because she was nostalgic. The chameleon circuit was not broken as the one in the Doctors TARDIS, but mostly Rose kept her in her blue police box outfit, because she liked it. Rose heard her humming in response and when she stepped insider her ship, she heard a voice in her head.

'My love.' Rose heard her TARDIS hum. 'I waited a long time to meet my mother's sister. Let me be of assistance with your memory.'

Rose frowned and stepped into the control room. When the memories hit her, Rose could barely hold on to the railing of the control panel to keep herself from falling to the ground. Her little TARDIS transferred the birth and death of the Bad Wolf into her head. Showed her how she had killed all Daleks surrounding the Game Station and how her first, the ninth Doctor, had silenced Bad Wolf.

"My head..."

"Come here."

" ...is killing me."

"I think you need a Doctor."

Rose could see the Doctor smiling softly as he said this words in a flirty manner, watched him leaning down to kiss the Time Vortex out of her head. She had a hard time not to start crying. Gaining this memory… it meant so much. Seeing her Doctor again, firting and giving her a kiss. A kiss she hadn't remembered for so many years.

Little One, as she liked to call her TARDIS, also showed her a message of her mother, the Doctors TARDIS. Rose assumed that the two TARDISes shared some kind of link.

'Dearest Sister of mine. Do not fear The Bad Wolf that has awoken within you. Bad Wolf has always been a part of you and has been sleeping for a long time. The time has come for you to wake up and rescue our precious Doctor once again. I will not allow the multiverse to separate us ever again. Come home, dearest sister of mine. We will show you the way.'

When the TARDIS' message ended, Rose realized that she had been crying. She simply could not believe that this was really happening. The TARDIS spoke in riddles, but she got the message. Rose would see her Doctor again.

No, she thought then. She was John's wife. The Doctor was a childish crush from her past. She should not look forward to getting her hearts broken once again. Now that she had two of them, it would even be worse if he rejected her. Rose was John's wife…

But was she still Rose Tyler?

'Yes and no. Just think of how the Doctor changed after regenerating. He is still the same person, with the same feelings, even if he looks different and likes different kind of food or clothing styles. You are still Rose Marion Tyler, but then again you are Bad Wolf and you will be so much more.'

Rose looked sadly to the doors of her TARDIS. "I have to say good bye to Tony."

When Rose had told her brother she'd leave this universe to find her Doctor, Tony understood. He'd said he would miss her, but could not keep her from finding happiness. He knew how sad it had been to watch her die and he would be glad that she would not have to watch him die now. That would have been the story, simply because there was no other being in this universe with Roses new life span. They didn't even consider her human anymore. Torchwood probably wouldn't like her sticking around anyways.

"As long as you are happy and alive, I can let you go, Rose. It is better than you waiting for your own death." Tony had told her with tears in his eyes. They hugged each other for a last time and then Rose left everything of this life behind.

"Okay, sweetheart! Let's find your Mum and our Doctor!" Rose yelled and laughed when she ran into her TARDIS. She started to pull ladders and pushed some buttons; until they entered the Vortex and remained floating through it serenely. "But first I got some re-decorating to do."

As much as Rose loved John's and her Doctors grungy and dusty control room, she had to get it a little bit more comfy and cleaner. Now it felt a lot easier to let go and she trusted the TARDIS to bring her back home. She asked the TARDIS to archive the room and got rid of the big corals. Seemed as if she wasn't as sentimental as her past self, Rose realized. Before she could start to worry about it, she telepathically showed Little One how she needed her to configurate the control room and the console.

Rose stood by the doors and watched how the room lit up and how the new panel and interior appeared within a mere second. The TARDIS burned up several unused rooms and Rose was glad, that they had recharged the engines shortly before John had died. Even after re-arranging the console room, there would be enough power to get into her primal universe.

Now there was lots of metal everywhere and clean cold lines. The walls still had the round metal pattern, but all much lighter and with a little bit of blue. The main colors where chrome and blue, as well as transparent highlights. The console was a less messy now. There still where a lot of ladders and buttons, screens and keyboards. She had kept Johns sticky notes and added only a few displays. Rose walked up to the control panel, over a few stairs and stood on a blue platform. There were two ways that led out of the control room. One led to the doors and the other to a hallway that led to all the rooms this TARDIS had to offer, as well as an entrance to the machine room, beneath the console.

While Rose entered the coordinates to Cardiff, the TARDIS nudged her mind and announced that her new room was ready. It would simply have been wrong to use the bedroom, which had belonged to her and John. Rose smiled sadly. "So... How do we get into the other universe then?"

Rose did not have to ask twice. 'Mother will guide us through a weak part of the dimension walls. Be sure to hold on to me tight.' Her TARDIS answered and Rose sat down on the bench and put the newly installed seatbelt on. It surely would be a bumpy ride. "Then let's get on with it, darlin'"

In another universe...

After losing Rose Marion Tyler, the Doctor had found comfort in crazy, little Amelia Pond and her little family. Although he had known better, he had let them into his hearts. Amy, the girl who waited as well as Rory, the Last Centurion and their daughter Melody; better known as River Song, the woman that had married the Doctor. He had loved all of them. But nobody would ever be able to replace his incomparable Rose Tyler. Not even the woman he had married in a collapsed time line. Especially not the woman he had married. The Doctor might love River Song, but he had never been in love with her, like he'd been with Rose. Sometimes he wished he had simply regenerated when that Dalek had shot him, never creating the meta crisis in the first place. That would have given Rose and him at least a good sixty years until her time was over. She would have been, once again, the first face this body had seen, but he had sent her away. He could have done it for her – the domestics – but only for her. He could not watch River die. When she had died in the library, he did not look back, or seek her out in that big computer that she was stuck in. Sometimes she haunted him, but he couldn't bring himself to answer to her calls. He did not look back, when Amy and Rory got trapped in another time line. He also refused to go on with his life at some point. The Doctor couldn't stand it any longer. He had lived too long. Invading random people's lives and dragging them along with him until he lost them in a battle he wasn't able to win, wasn't an option any more.

One day the Doctor was sitting in his room aboard the TARDIS, waiting for time to go by the normal, boring and short way, he was rather surprised when suddenly the engines started on its own.

"What do you think you are doing?" He yelled and jumped up, rapidly running towards the console room. "Stop it! I built you a beautiful hiding spot in a cloud! Hey!"

It was a difficult and very bumpy ride through the walls of the multiverse. Rose tried to hold on to the seat, but almost ripped off the safety belt twice until the TARDIS landed with a big bang. She hoped that they had reached the Cardiff in the right - in her old - universe. Traveling through the walls of dimensions cost a lot of energy and the TARDIS would be in need of a quick energy refill. The rift in Cardiff would be the perfect booster.

When the TARDIS finally halted, Rose opened the seat belt and ran outside to see if she had reached the right universe. The first things she could see or better could not see were balloons in the sky. Not even a single one. Rose started to laugh, almost hysterically. She couldn't believe that she had done it once again. Getting back into the universe she really belonged. If that hadn't been enough already she suddenly saw a figure standing not so far away. Could it be true?
"Rosie!"

A smile appeared on Rose's lips and she ran towards one of her best friends. He still wore that old World War II coat that fit him so greatly and that sassy grin she always had admired. Rose jumped into his wide opened arms and laughed happily. "Jack! It is so good to see you again." She huffed when he hugged her tight and pressed his lips against hers briefly, like he liked to do.

"I thought I'd never see you again, Rosie." He said with tears in his eyes. "Thought we'd lost you for real this time. Where is he?"

When he let go of her, she moved away a little and looked at him. He hadn't aged a day, just like her. She still felt guilty for bringing him back forever. Rose knew that he wouldn't be pleased to outlive everyone he loved.

"Not with me. This is my own TARDIS from the other universe." Rose explained. "Have you seen him lately?"

Rose didn't need to ask what year they had. She could taste it in the air. Felt it in her bones. See it in Jacks eyes. Almost 4 years had passed in this universe since the Doctor had left her and John on Dårlig Ulv Stranden. Slowly she could see the world like the Doctor always had tried to explain. It was fantastic and exhausting at the same time.

She saw that she had asked a question that hurt Jack deeply. "He can't stand to be around me. I am a fixed point running around in this universe. Also, he is still guilty for something he didn't even do and don't be scared, Rosie. I am not mad at you for bringing me back to life." He smiled at her reassuringly. "I haven't seen him for years. He does not visit and I can't even hate him for it."

"I am not sorry for bringing you back, but it scared me how much pain I have caused you since." Rose tried to hold back her tears and hugged him tight. "The Doctor never told me what I did to you. I just found it out a few days earlier."

"Like I said, don't be sorry. Let me look at you. You haven't aged a day."

Out of a sudden they could hear a very familiar sound. Rose turned around fearing her TARDIS was abandoning her here, but it wasn't Little One. Bit by bit a second TARDIS was materializing right beside hers.

Rose turned away from Jack and they both stared at the second TARDIS. Was it really that easy?

When the groaning finally faded and the TARDIS had landed, Rose waited until the door opened and someone popped his head out, looking where he was briefly. He was young, had lots of floppy hair and a … big chin.

"Why did you bring me to Cardiff, you crazy old girl!" Rose heard the strange man yell. Yep. That was definitely the Doctor and he seemed to have regenerated once again. His head disappeared in the TARDIS once again and Rose could hear the lock click. He intended to leave! How could he dare?!

Rose sprinted forward to the TARDIS and grabbed the doors knobs, pleading telepathically to her sister to open up for her. The Doctors TARDIS let her enter immediately and she came to a quick halt as she saw the re-designed control room. The corals were gone, just like in her own TARDIS. The both control rooms of mother and daughter looked a lot alike, even if here was more silver and in Rose's were more blue elements.

"Who dares to enter my ship without my consent?!" The Doctor yelled and turned from the console to face the intruder. Rose simply stared at him, not sure what to say. She might be an eighty-something year old Time Lady now, but this hadn't prepared her for this very moment.

Her Doctor was no more. A young, but still elder Doctor was looking at her with disbelieve and shock in his oh so old eyes. What had happened to him, she wondered, and couldn't help but stare at him.

"I know why I deserve to be punished, but why does it have to be you?" He said. Rose could hear the hurt in his voice. She could see the tears gathering in the corners of his eyes. "Whatever you are, how can you dare to impose her?!"

Then Rose understood. "It is me, Doctor." She said and moved forward, walking down the stairs towards him. "I came back."

"NO! It is not my Rose Marion Tyler, Defender of the Earth! She is living happily ever after with his clone!" Now the tears were streaming down his cheeks. Seldom had she seen him cry. In fact, she had never seen the Doctor cry, while John had shown her his tears from time to time. Rose hated to hurt him so much, but she had to convince him that she was indeed real. The Doctor fell down to his knees and buried his face in his hands.

Quickly she walked closer to him and put a hand on his shoulder. The other found its place on his jawbone rising up his head slowly, so she could look into his eyes. The TARDIS guided her and told her to make closer contact. Rose smiled widely at the TARDIS meddling but obeyed. "Let me prove it." Rose whispered and kissed him carefully, concentrating hard on showing him what had happened to her since he had abandoned her and John.

The Doctor tried desperately to move away from this mad woman, but he couldn't bring himself to move away from her or shove her away from him. She still looked like his long lost love and even if it was only an image of her, he couldn't hurt her. She even smelled like her.

When she made him look into her eyes, he almost lost it. He looked into deep golden eyes. No, this could not be Rose; hence his beloved Rose had stunning chocolate brown eyes. Also, her eyes looked wrong, but he couldn't tell how.

Out of a sudden their lips touched and images exploded before his eyes. His tenth self leaving Bad Wolf Bay with the Doctor Donna, leaving Rose and the meta crisis behind with a TARDIS coral. He saw Rose crying in the meta crisis' arms. The pictures moved faster and faster. He could see them all at once. Rose and John Nobles wedding. Jackie Tyler's funeral. Tony Tyler growing up in this big mansion. Rose and John traveling through the TARDIS they had grown for themselves. John Noble dying peacefully in Roses arms. Rose waiting for her own death beyond the starlit sky and only moments later regenerating beyond that very same sky. The TARDIS explaining that Rose was Bad Wolf, which had been lingering in the back of Roses head, never really gone, only temporarily put to sleep. And then he saw her looking at the second TARDIS and him peeking out without even noticing her. After seeing all this, the Doctor gladly gave in and kissed her back.

Rose pulled away reluctantly, when he had seen everything and started to move into the kiss, but they had to talk. He looked at her with these big, sad eyes. Shocked about everything he had seen, but with a little bit of relief of having her back.

Both of them slowly started to move away from each other, not sure what to do next. "You really came back." He finally said and still looked at her in disbelieve. At least he had calmed down.

"Yes and I do not intend to leave again." Rose told him and hoped that he got the message. He wasn't allowed to leave or let her behind ever again either.

She looked at him and tried to take in everything. He had changed so much once again. He was still a pretty boy, but he wasn't the one that had been made from their love. But she could easily live with that. All that mattered was them being together again. He had a solid face. The chin. What more was to say? He was still tall, maybe not as tall as before, but she didn't care. His hair was fabulous. Not spikey and styled, but floppy and wild. His eyes were ocean green and she couldn't help but chuckle at his outfit. The velvet purple tweed jacket fit him well and he wore a bluish bow tie. On everyone else she'd have thought it looked ridiculous, but he could easily pull that outfit off.

"Oh my god. I regenerated." He suddenly blurted and she was laughing a little. She watched him stroking through his hair and looking lost, nervously moving his weight from one foot to the other and trying to adjust his clothes.

"I kinda got that."

He didn't seem satisfied with that statement. "Is it okay? Do you like it? How did you know it was me?"

Rose smiled her tongue-in-teeth smile happily. "It is very okay and I fancy every bit of you. I did regenerate as well so we're fine. Oh, before I forget it, I love the bow tie."

She had thought that would make him laugh and happy, but all she got was a serious look on his face and out of the blue he grabbed her arm, pulled her close and kissed her fiercely, as if his life depended on it. Rose happily gave in and wrapped his arms around his neck, chuckling into the kiss.

"You, Rose Tyler were made for me and before anyone or anything can stop me again, let me finally finish this bloody sentence… Rose Tyler, I love you."

It were those three little, but so very important words she had needed to hear. The moment he had spoken them, the world halted for a second. Everything that had mattered before seemed to float away. Everything that had bothered her seemed to be meaningless. In this second, it was only him and her. The Doctor and the Bad Wolf were finally together in the TARDIS where they belonged.

"…Rose Tyler, I love you."

To be continued...

Disclaimer: I do not own Doctor Who.

Authors Note: I have never cried over anything, like I cried over the last scenes between The Doctor and Rose. I even cried harder when they did it again! How could they? I mean, it was clear that Rose couldn't stay forever, it is just not that kind of show, but still...
It can't happen in the show, so someone else had to make it happen. At first a read a few Reunion-Fics. I loved most of them, but it didn't feel right mostly. So there it is. My own Reunion-Fic. I hope you like it was well!

Thank you for reading. I am also sorry for all mistakes I made, my native language is German and I am still learning. Also I had no beta, would be great if someone volunteered :)

I would love to know what you think about it and be sure, that there will be a second chapter and maybe even more. Because I simply love what happens after the 'and they lived happily ever after'

You can also visit my tumblr bercelak and watch a Reunion vid I posted. Would be great if you'd check it out. I intend to be lots of active there now as well :)

So stay tuned and thank you again!
