The duo caught up with the man just as he opened the door into a small storage shed. "Oi!" The Doctor yelled at him, "Who in the blazes are you, and how do you know who I am?" The man smiled faintly. "Always curious, that's the Time Lord way." The Doctor smirked. "And you would know?" the man glanced at him. "Yes, I would," he said as he walked into the shed. The Doctor and Rose ran at the door and barged it open, only to fall into a much larger room. It was completely spherical, with a platform in the centre. Corridors led off in all directions, and lights punctuated the dark walls. Rising up from the centre platform was a tall pillar, the bottom bristling with controls. "It's...it's a TARDIS," Rose said, looking around. The man leant against the centre console, grinning. "I would know... because I am one."``
