The first thing of note were the Doctors jacket pockets. They didn't seem normal. At least one of them wasn't, fitting far more loose and random objects in it that should have been possible. He carried a sonic screwdriver in the inside jacket pocket, along with his psychic paper. Inside one of the exterior pockets, there was a variety of what looked like junk. A bag of sweets, a yo-yo, a small wind up car, some money. Toys and odds and ends from all over their universe and some items he had picked up on the station.
His double heart beat gave away nothing, but that wouldn't last terribly long. Neither did his face for the time being. A little smirk remained, and his expression was calm. His posture, relaxed.
"Really?" he replied. "Not important" he paused to take a quick breath. "Why are you here and how did you get here?" he asked, tilting his head to the side just a touch.
