The Doctor shrugged out of his coat now as he walked inside the TARDIS, throwing it over its usual place on one of the pillars and approaching the console. "Where do you want to go? Seems as if you need that tea."

He leaned on the console, looking up to watch Billy, one eyebrow cocked. "You're nervous. Very nervous. What is it, me knowing your secret? Don't worry about it, it's not your fault. It's very difficult to hide things from me. Believe me, I've tried before, but I always catch up to myself pretty fast."
