So here's part 5. Yay.

I hope you all enjoy. Took some time to write but this is the longest chapter so far. Only by a little bit. I think there will be one more chapter after this.

Disclaimer: I don't own Doctor Who, if I did Billie wouldn't have left and they really would have gone back to get Jack.

Part 5: Danger

"ROSE!" the Doctor cried out in anguish. She was now slumped on the floor and her body was twitching, violently, he wanted to go to her, hold her, keep her safe.

Jack was confused to say the least, he hadn't a clue what was going on. Everything was happening too fast, far too fast. "Rose." Her name escaped his lips in a whisper, Zoe, this girl was doing something to her, hurting her. Killing her. "Please, let her go, please!" Jack was begging, he'd only just got the Doctor and Rose back, he couldn't lose her so soon.

"Let her go?" Zoe's voice was calm. She then laughed cruelly, "But she is a threat I cannot let her go!" her voice began to sound almost sadistic. Jack's mind was racing at 200 miles per hour, he had to think; ok Zoe 'nice' 17 year old girl was holding himself the Doctor, Rose and the TARDIS and was refusing to let them go. There was very little he could do. Jack swallowed hard his eyes flitting to the Doctor and then back to the young girl who held all their lives in the palm of her hand.

"Sit!" she said calmly pointing to the floor, and like before, Jack obeyed but the Doctor didn't.

"Or you'll what?" he asked challenging her.

Her eyes were wide; "Or I'll kill her!" she spat dangerously, the Doctor maintained eye contact with Zoe as he lowered himself to the floor, the moment he had done so, Zoe seemed relax and released Rose. Rose's body ceased convulsing and she lay perfectly still. Now a sickening silence had surrounded them. The Doctor was sat next to Rose. He reached out to her his eyes still on Zoe. He pulled Rose upright and checked her pulse as he laid her body against his.

"What did you do to her?" Jack asked finding his voice. Zoe smiled slightly, her eyes flickered over the three of them.

"Used her own power against her, I thought that would be clear!" she said calmly. Jack felt a sudden wave of rage towards her, she was only a child how could she cause so much damage.

"But…how?" the Doctor asked, he was confused, he thought he'd removed the time vortex, all of it. "Rose shouldn't have any power…Bad Wolf, shouldn't exist anymore!" he stated strongly. It was now, in the light, that the Doctor took in the appearance of this girl, she had dazzling blue eyes and pale skin, her hair was dark and her face would have been a kind one, had it not been for the sneer that now resided as her expression.

Zoe laughed, the Doctor knew so little; "You mean you couldn't feel it? Couldn't sense the power radiating from her? Didn't you ever wonder why Rose didn't die the moment she took the time vortex in her? Didn't you ever stop to think, wait a moment I'm a Time Lord and it 'killed' me, she's only a human and she's fine…you can be very dense sometimes you know that Doctor!" the Doctor glared at her with her last comment.

"I never…I…oh Rose…" he whispered her name. Jack was left trailing, what was going on? Who or what was Bad Wolf, what did it have to do with Rose and why shouldn't it exist anymore? He hadn't been filled in on everything, it would seem.

"Doctor?" Jack spoke just as Rose stirred, the Doctor gave him a look which meant –later- he wasn't ready to tell him everything, not when he hadn't told her yet.

Rose's eyes drifted open, her head was pounding again and her vision was slightly blurred; "Doctor?" her voice was a whisper but he was there he'd heard her, he held her tightly whispering in her ear. Telling her everything would be ok. Rose looked up as her eyes began to clear the haze faded and she felt her body begin to shudder, a pain from deep within her soul was telling her that danger was afoot and that only she could save them.

Bad Wolf. Rose you are their salvation. The power within. Your power. Harness it!

A voice from inside her was screaming, she didn't understand what was Bad Wolf and why was she the only one who could save them. Save them from what. Zoe. The voice was talking to her now, responding it didn't make sense, she had to be going mad. Those Torats had done something to her brain sent her mad, implanted a probe the voice in her head most certainly wasn't hers. She was shaking her head now trying to rid herself of images that kept flashing into her brain, these couldn't be her memories. Couldn't be.

"I can see the whole of time and space, every single atom of your existence, and I divide them!" These thoughts burned, she shouldn't remember, wasn't meant to. This was wrong. Rose screamed again her heard aching, she couldn't take all these memories.

Jack looked over at her worried the Doctor was still holding her, but there was something wrong they could both tell, Rose was in pain and Jack didn't know why.

"Doctor? What's going on?" Jack asked frustrated at being left so in the dark. The Doctor took a deep breath.

"You remember when the Daleks were attacking Earth and I sent Rose away?" He asked, Jack nodded; "well Rose wasn't having any of that, and she looked into the heart of the TARDIS, took the whole of the time vortex in her. No one's meant to do that, she was dying, but before that happened she destroyed every single Dalek with a wave of her hand…every single one. Gone. She brought you back from the dead, changed fate and history and time, bent it to do her bidding, but it was killing her, so I being me, had to save her, I took the time vortex into me, I thought I got it all out, but I didn't, I managed to block off the memories, but those Torats were rummaging around in her brain must have made her remember, those memories are hurting her. She doesn't understand!" the Doctor finished sadly, obviously blaming himself.

Jack looked up at Zoe; "You're killing her!" he spat, anger coursing through him once more.

The Doctor was now preoccupied with Rose, he needed her to wake up, to stop screaming, to look at him with those dark brown eyes, he needed to see life in those eyes, so expressive, so full of love. He needed his Rose. Now.

"So what if a stupid ape dies, she's insignificant, not important…not anymore…once I have taken Bad Wolf from her all of the Time Vortex, I'll be able to harness the power, to destroy…and maybe save a few universes, depends on how I'm feeling!" she was so cold, she didn't sound innocent or human anymore.

The Doctor leapt to his feet; "You can't do that!" he yelled, shock exuding from his every pour. "You'll kill her, and now I know you don't care about her, but I do. And you see, holding me captive on my own TARDIS is one thing, but killing Rose? Hurting Rose? Now that's another, because if anyone, and I mean anyone, hurts her. They'll have me to answer to. And you don't want that. 'Cause you'll have made me angry and believe me, you wont like me when I'm angry. Now give her back to me, or you will feel the wrath of the last of time lords and believe me, I'm not like the other time lords I've learnt my lesson the hard way and mercy isn't a word in my vocabulary when it comes to those hurting Rose!" Jack had also got to his feet, he was standing beside the Doctor, this was a new side he'd never seen before, a rage like no other, this was the 'Oncoming storm'. Jack placed a hand on the Doctor's shoulder, it calmed him slightly and he stopped seething. Zoe had taken a step back, she too was in shock.

"You're in no place to threaten me Doctor!" Zoe said regaining her composure, she would not be beaten so easily.

Rose opened her eyes, she stopped screaming and a silence rang clear, the Doctor didn't stop looking at Zoe but Jack's head span to look at Rose she got slowly to her feet; "I am the Bad Wolf I create myself!" Rose spoke old words, that meant so much. She was glowing, only slightly but she was still glowing, there was no doubt about that. Jack's mouth fell open, he was shocked to say the least.

"Oh and another thing, you can't take the time vortex, unless you're me of course and you're not. Bad Wolf is Rose, Rose is Bad Wolf and you can't take it from her, it'd probably kill you in the process." The Doctor stated matter-of-factly, Rose was now by his side.

"I want you safe my Doctor!" She said those old words again. The Doctor grimaced.

"Look Rose, this is me, being safe!" he said smiling his cheery smile, in his head he imagined his old self saying this to Rose. Rose had smiled at him. "There's my Rose!" he said grinning at her.

"You…caused pain, so much pain…" Rose was looking at Zoe now, it was clear she was trying to regain her control over Rose but Bad Wolf had taken over and there was no stopping it.

"I'm…sorry I didn't mean to please, please don't hurt me!" Zoe was begging Rose now, begging for her life to be saved, the pleas fell on deaf ears. Rose's eyes narrowed, she had no mercy.

"Don't! Doctor you have to stop her!" Jack said horror struck, the Doctor's brow furrowed, Jack was right.

"Rose, I'm safe now, you don't need to hurt her, please Rose no more pain…" he whispered holding her arm. Her eyes met his and she saw his begging, she nodded slowly and there was a clattering sound as Zoe hit the floor, Jack rushed forwards and held her so she wouldn't cause anymore pain or trouble. Rose stopped glowing and she fell into the Doctor's awaiting arms.

"Is she ok?" Jack asked worriedly.

"She will be." The Doctor replied. He could still feel her pain, she was aching and it would take some time for her to heal properly. But time would do it's magic.

A/N: Yay. Everyone's gonna be ok. Apart from Zoe but oh well she was evil. Review please.
