This was interesting. The TARDIS had picked up a ship. A SHIP! It seemed to be in near orbit, and probably capable of interstellar travel.
The Doctor monitored it for some time. It seemed perfectly functional, minus it's crew. Friendly or hostile, it seemed very well armed, and grossly understaffed.
The teleportation got his attention. It was the only use of quantum technology in the City, beyond his. He decided to put on a nice tan suit, trench coat, and say hello.
Walking the streets, the Doctor followed the keening of the Sonic Screwdriver. It homed in on the signal. He noticed the oddly dressed man with his own sensing device, and pointed ears.
The Doctor smiled at the stranger. "Long way from home?"
