Rose leant back on The Doctor's coat. "So, you've never met him before?" The Doctor turned his head to look at her from where he was lying next to her. "No, but I think I've heard of him."
"What do you mean, you think you've heard of him?"
"There was stories, back in the Time War, of a warrior, one of the greatest warriors Galifrey has ever known. It was said he destroyed thousands of Daleks, and everyone who ever met him feared him."
"Feared him? Why would they fear him if he was on their side?"
"Supposedly, this warrior was so fierce because he was insane. He would laugh hysterically on the battlefield, and wouldn't even be bothered by any shots that hit him. There was a ton of theories why he was so crazy. Some people said that he had been experimented on by the Daleks, and had escaped. Others said that he had fought so much, he had lost his mind. In any case, I think this warrior was The Vigilante."
"Ah." A light started flashing behind them, and the TARDIS faded back into existence. The Vigilante stuck his head out the door. "I know why the Descart can't rebuild the ship themselves. Ten bucks says you can't guess." The Doctor looked up at him. "Because they're intangible?" The Vigilante's mouth fell open. "How did you know?"
"We've been watching from up here."
"Cheater!"
"You never said we couldn't."
"Damn your logical thinkingness!" The Vigilante disappeared back inside the TARDIS. The Doctor grinned as he stood up. "We'd better get in there before he takes off again."
