"Run!" The Doctor yelled as the Dalek bore down upon them. He and Rose turned, and sped down the hall. The Dalek trundled after them. "Exterminate the Doctor! Exterminate Rose Tyler!" it screeched. Beams of compressed tachyons flew past the duo. They glanced back, and Rose grinned. "I think we're losing it!" she cried, before they both promptly ran into a wall and crashed to the floor. The Doctor looked up at the low ceiling, spread-eagled on the ground. "Ow." Rose winced. "My thoughts exactly." They scrambled to their feet as the Dalek stopped in front of them. "You are defenceless. You will be exterminated", it droned. Rose clung to the Doctor's arm. "Alright, now is a good time for a fancy plan," she said. The Doctor turned and looked into her eyes. "I'm sorry", he whispered.
It was at that precise moment that the Dalek exploded.
Rose grinned. "Nice job. What'd you do, rewire his circuits? Overexert his weapon?" The Doctor looked around, confused. "That wasn't me." Rose's face fell. "What? You didn't blow up the Dalek?" The Doctor pulled out his sonic screwdriver, and started scanning the area. "Nope. The question is, who did?"
"Yeah, that was me."
