Disclaimer: I do not own the wondeful Doctor Who or his 'cheeky companion' Donna nor the beautiful Rose Tyler, and I don't own those two epic words; BAD WOLF, and I don't own most of the dialouge written here, it is kind of my take of the end of the most recent Doctor Who episode.
Doctor: "It is I, the Doctor, and my cheeky companion Donna Noble"
Donna: "I am NOT cheeky"
Doctor: "Donna, Donna"
Donna: "I am not cheeky, why do you always say that??!"
Doctor: "Its a quite admirable quality Donna"
Donna: sighs "I am NOT chee..."
Rose: "Will you both shutup already, and get on with the story"
Me: "All righty, here goes..."
"You're brilliant Donna Noble" The Doctor grinned his trademark grin.
Donna smiled, but suddenly she froze "That's what she said"
"Who?" the Doctor questioned, a little to eagerly.
"That woman" Donna said, almost questioning herself.
"What did she look like?" the Doctor asked slowly, cocking an eyebrow.
"She had" Donna gestured to her head "blonde hair"
"What was her name?" the Doctor said.
"She never said, but..." Donna trailed off and thought."She said that the stars were going out, that the darkness was coming"
"But that was in a parallel universe" the Doctor sighed lightly.
"But she said that the darkness would effect every universe, every single one."
The Doctor froze "What was her name Donna?"
"I told you, she didn't say, but she did say for me to tell you something..."
The Doctor's dark brown eyes peirced Donna's blue ones.
"Two words" Donna continued, pondering them silently.
"What were they?"
Donna stopped and said in a still questioning voice "Bad Wolf"
The Doctor bloted up, images of a young blonde girl filled his head. Rose Tyler. The one he loved. "Bad Wolf" he repeated "The end of the world"
