Rose took several deep breaths and stepped out of the TARDIS onto the Powell Estate where people were being exterminated by invisible forces. Other people watching from the hiding places were just seeing people drop down. Only Rose could see her imagined Dalek's.
They whole world paused as she walked forward. The Dalek's turned to look at her and anybody who'd been watching the invisible terror was now amazed to see one bedraggled, scared looking blonde girl standing in the middle of the square, unharmed and apparently talking to herself.
"I order you to leave this planet!" Rose said in a voice barely more than a whisper. The Dalek's turned to look at her.
"Dalek's do not take ord-ers!" The Dalek screeched at her. Rose swallowed hard as the Doctor cautiously stepped out of the TARDIS as well. The Dalek's turned their attention to him now. "Doc-tor de-tec-ted!"
Rose looked at him wide eyed and several Dalek's surrounded him. Though the Doctor couldn't see them he could sense their presence.
"Stop them Rose," he said quietly, looking her straight in the eye. "It's not real, none of it's real, but you have to stop them before they kill anyone else."
Rose opened her mouth to reply when she heard the worst possible sound. Footsteps and cries as a woman ran towards her. Rose turned back to see her mother running towards her.
"Rose! Rose love, get inside! People have been dying! They're just zapped-" Jackie ran past the Dalek's oblivious and they all pointed their guns at her.
"The hu-man must be ex-ter-min-a-ted!" The Dalek's intoned.
"Mum! Stop!" Rose shouted holding her hands up. Jackie froze and Rose turned to the Dalek's. "Don't kill her!"
The Dalek's around the Doctor suddenly pointed their guns at him.
"The On-com-ing Storm must be ex-ter-min-a-ted!" They cried. Rose looked at them her face etched with worry.
"No!" She cried. "Please! Don't do anything!"
"The Dalek's must follow orders!" One of the Dalek's screeched. "We must ex-ter-min-ate!"
"No! You can't!" Rose said looking at all the Dalek's desperately. "Leave them alone!"
"Rose, who are you talking to?" Jackie asked quietly, looking as if she thought her daughter was mad. The Doctor put a finger to his lips though and Jackie quietened.
"The Bad Wolf must choose!" Another Dalek said. "You can save one. You must choose which dies!"
Rose paled. This was way too much. She couldn't choose between her mum and the Doctor. Especially when these Dalek's were her creation. That would mean she was literally going to kill one of them.
"I can't!" Rose said weakly, sinking to her knees. The tears flowed freely now. "I can't do this. I can't… I just CAN'T!"
The Doctor watched as Rose collapsed, covering her face with her hands as she sobbed. He couldn't let her go through this alone.
"Rose," he said quietly. "You know what you've got to do. You can stop it all, you just have to concentrate. You don't even have to use the Bad Wolf."
A sudden thought had occurred to him and he thought he knew how he could help Rose even if he couldn't reach her.
"They want me to choose!" Rose shouted at him. "They want me to kill either you or mum. How can I stop them?"
"Remember what Chloe did when the drawing of her dad became real?" The Doctor asked not taking his eyes off Rose. Rose looked up at all the Dalek's, her face tear strained.
"Yeah…" she nodded. "She sang, but I don't see how-"
"She sang because she felt alone," the Doctor cut across. "You're not alone Rose, you might be the only one who can save the day and the only one who can see these Dalek's, but you're not alone."
"CHOOSE!"
"CHOOSE!"
"CHOOSE!" The Dalek's were getting impatient and started chanting at Rose. She looked up at the Doctor desperately and something told him that though she was on the brink of insanity she could just cling on.
"Kookaburra sits in the old gum tree," she muttered trying to ignore the continued cries of 'choose' from the Dalek's. "Merry, merry king of the bush is he…"
Jackie opened her mouth to speak but the Doctor shook his head. The Dalek's looked at each other in an almost confused way and Rose stood up feeling a little stronger.
"Laugh, Kookaburra, Laugh, Kookaburra," She sang her heart pounding. Glancing down at her hands she could see a familiar golden glow surrounding them. "Gay your life must be."
"That's it!" The Doctor said. "Keep going!"
"Kookaburra sits in the old gum tree," Rose glanced at the Dalek's and could see them starting to fade. They were feeding off her fear, so now she was feeding off them, taking the power of the Bad Wolf back and using it against them. "Merry, merry king of the bush is he."
Rose held her hands out wide, palms facing the Dalek's and she did the same thing she'd done before. Divided their atoms, taking back the power that was rightfully hers.
"Laugh, Kookaburra, Laugh Kookaburra," the Doctor could see Rose's eyes beginning to glow and her voice turned ethereal again. "Gay your life must be."
The Dalek's disappeared, the Doctor could sense they were gone and began to walk towards Rose. She stopped singing now and looked at the Doctor, tears still falling.
"I want you safe, my Doctor," she said, repeating her words and smiling before she collapsed into his arms.
The Doctor caught her and scooped her up. Jackie ran over hair flying about all over the place.
"What the bloody hell was that?" She asked in a frightened tone.
"That was the Bad Wolf," the Doctor said smiling slightly.
