Hello again! New story, fresh start! I'm keen! So this is a little 'teaser', if you will, for my new story/re-write! I hope you guys like the general idea. Reviews are always welcome!

Disclaimer: I don't own anything.

Rose walked across the dark car park behind Torchwood. It had been a long day and she didn't feel like they'd accomplished anything. A shadow near her car made her stop dead. "Hello? I swear if someone's mucking about".

A figure appeared next to the car still in the shadows, "Is that you Jake? I've had just about enough of you and Mickey alright?"

"Hello Rosie," said a very familiar American accent.

"Jack?" she asked, bewildered, "Jack is that you?"

He stepped into the light and his now visible grin widened, "Been a while". He looked exactly the same as he always had on their adventures together, same coat, same pants, and same haircut.

"Oh Jack, you nearly gave me a heart attack, what are you doing here?" She ran to give him a hug.

He spun her around than sat her down gently on the concrete "Well Rose, you'll be happy to know I'm here to help you"

"How are you gonna do that then?" she asked, grinning at him. It was the first time in months that she'd ever felt truly happy.

Jack's face got serious, "I'm going to send you back, Rosie".

She stared up at him, "How? Jack how did you even get here?" She'd been too busy being excited to see her friend that she'd never even thought about the impossibility of him being there.

"That is a very long story. Come on, I'll shout you a coffee".

The diner they went to was small but homey, back in her own world Rose had come to it for her very first date with the Doctor when they had chips.

"Ok Rose, here's the thing. I've travelled across dimensions to get to you, you know I wouldn't do that unless it was one hundred per cent necessary," she nodded in agreement, "It's very dangerous, but we need you back".

"What do you mean we? Do you mean the Doctor, was he with you?"

"No Rose, he's got a companion and is travelling the universe again". He noticed the pained expression on Rose's face, "I'm sorry to put it like that but in his eyes he has to move on, like he always does".

"No, don't worry I get it" said Rose, trying to fake a smile.

"If it's any consolation to you, she's not as pretty as you and he's totally not interested in her," said Jack, sipping his hot coffee.

Rose smiled, it was genuine this time and Jack felt a little more relaxed. "So why are you taking me back? If he's moved on what use would he have for me?"

"Well, you see Rose, when you were taken to this universe and you were trapped, the universe had to try and fill the hole that you left".

"What do you mean? People die every day Jack, and it doesn't make a shred of difference".

"But you didn't die, Rose, and you aren't just a normal person. You are the Bad Wolf, the one, the only, you are one of a kind and there is no other Rose Tyler in any other universe because you were meant for something greater".

"What do you mean greater? Am I supposed to live amongst all galaxies as some kind of superhuman or something?" she snorted.

Jack nodded and she looked at him with her eyebrows raised, "Yeah pretty much, you, like the Doctor, were meant to shine high over the galaxies, ancient and forever".

"Jack I'm not forever," she sighed, gesturing to a bandage on her arm, "Nearly cut the femoral artery. I nearly bled out and you're telling me I'm supposed to last forever".

"You haven't heard the rest of my plan yet," said Jack, patting her hand, "Rose, I'm going to send you back".

"What do you mean back?"

"Back in time to when you first met the Doctor".

"But why? I don't wanna see it".

"Not to see it you goose, to live it. I can physically take you and put you in your true place as Rose Tyler, the Doctor's companion".

"But won't I be interrupting the past version of me?"

"You're the Bad Wolf, if this goes to plan the past version of you will still live the same life and live to do it again as you will soon".

"But how is that possible?"

"It complicated Rosie, really complicated. The point is, if I send you back there and you live through that life again, when it comes to Bad Wolf you'll actually absorb it properly. He'll still try to save you and he'll still regenerate into the pretty boy, but you will be powerful, very powerful".

"So I go through all of it again with him and I'll become powerful after Bad Wolf?"

"Pretty much yeah, but you can't let him know until after you've succeeded in avoiding the whole Battle of Canary Wharf incident".

"So if I do this I will live forever?"

"Not forever. You'll be truly bonded with the TARDIS then and you'll live as long as it does, which I might add, is as long as the Doctor does".

"So forever," Rose repeated grinning, "So if I do this what do you get out of it?"

"Our universe has got a big hole in it Rose, literally, a black hole is endangering many of the planets and the Doctor doesn't know anything about it".

"How can he not know about it?"

"He is trying to avoid even thinking about you Rose, it doesn't work very well for him but he tries. That hole is the space you left in the universe. Bad Wolf is important and if you succeed in avoiding Canary Warf the hole will patch itself up and the universe will be able to move forward".

"So let's see, you're proposing I go back in time and relive my life with the man I love, become practically immortal, and you're going to help me in order to save the universe?"

Jack nodded, grinning "I thought that would sound pretty good to you, but there are rules Rosie".

"Then let's hear them".

"You can't let him know that you are reliving things. don't make it obvious that you know what's going to happen, and Rosie, please don't snog him the moment you see him again, it might not go down too well as a first impression".

"Depends how good you think I can snog," she teased cheekily.

Jack laughed with her for a moment before becoming serious and business-like again, "But seriously don't do anything too rash and don't rush the relationship between the two of you".

Rose nodded slowly, "I'll try my best".

"So you're in?"

Rose laughed "Are you kidding? Jack this is the best thing I could possibly have imagined happening".

"Great," he hugged her from across the table, "Come on, this calls for something a little bit stronger". He took her hand and led her across the road to the bar. "A toast to the Big Bad Wolf".

"Who are you calling big, mister?" she asked, punching him on the arm.

He faked a pained expression, "Come on seriously, toast with me".

"Oh alright then, to the Doctor".

"Oh and Rose, I don't want to rain on your parade but I do have to warn you what will happen if you don't succeed".

"Why? What will happen?"

"Well, the universe will collapse on itself and…I'm sorry Rose but the Doctor will die".

"What?" she spluttered, spilling a few drops of her champagne.

"He'll die, the Bad Wolf is still inside him as well but if the universe tries to flush the remains out of its system he'll be sucked in as well. There's no way he can avoid it".

"But he's a time lord, his people invented black holes".

"They didn't however, invent the Bad Wolf and that is what will happen".

"Well then, since you've officially rained on my parade shall we get to it then?"

"I think you'll need a good night's sleep first. I'll come to your apartment in the morning".

Please let me know what you thought of it. The whole 'black hole' thing might be a little bit controversial but I thought it fitted well.

I hope you like it and next chapter will be up soon :)
