Prologue.

Rose winced in pain, staggering under the weight of the Doctor's unconscious body. She was breathing heavily, and knew they had to get out of there quickly, before it was too late. It was all her fault and she knew it, tears building up in her soft brown eyes.

"Oh God, Doctor," she gasped, the tears beginning to cascade down her flushed cheeks. "I'm sorry, I'm so sorry…"

The Doctor groaned softly and Rose collapsed to the ground, leaning over his limp body and watching his face as he came to. She bit her lip to stop from howling as the Doctor's dark eyes fluttered open and he groaned again.

"Rose…"

"Doctor, I'm so sorry," she sobbed. "It's all my fault, I should've known better."

"Rose, shut up," the Doctor slurred as he tried to sit up and failed. "It could've happened to anyone."

"But you nearly died."

"Ah, nearly, but I didn't," he said with a weak smile and finally struggling into a sitting up position.

"So what're we gonna do?" Rose asked nervously, fiddling with her sleeves. "Or me at least. You're too weak to do anything, and it's my fault."

"Rose, will you stop blaming yourself!" the Doctor said with a pained expression. "I'll be fine."

Just then there was a loud bang and they both froze in horror.

"He's coming," Rose whispered. "I've got to stop him, before it's too late…"

"Rose, listen to me," the Doctor instructed urgently, turning slightly to face her. He gripped her hands tightly in his and looked deeply into her eyes, seeing the terror in them. "Rose, the only way to stop him is to look back. Almost all problems can be solved by looking at how they started. I'm too weak to follow or help, so it's up to you now Rose. The Universe depends on you."

"Oh, so no pressure then," she said with a humourless smile. The Doctor smiled back at her.

"Rose, you know I probably won't make it out of this alive. It's me he's after."

"Doctor, don't say that!" Rose said tearfully. "I'll save you Doctor, I promise."

"Good luck," he said seriously, letting her hands fall from his. "Good luck, Rose Tyler."
