Anyone not a version of the Master
The Doctor stepped out of the TARDIS, and stopped short. He appeared to be no where neat where he'd thought he'd be. He reached out and patted the TARDIS, "That's been happening much less since we gave you an overhaul. There's no way I got the coordinates wrong. What's the matter? Did something grab your attention?"
He stepped back in, and checked the coordinates anyways. He's set them correctly, but all his other instruments said he was both no-where and no-when. But he was clearly somewhere. How very strange. Well, he didn't need to go home right now, that was the joy of a having time machine. Might as well take a look around. Might be fun. Might be some trouble that needed fixing.
He ambled around looking to see if there was anyone else in the area. He wandered up to the first person he saw, put on his brightest grin, and said, "Oh, hello! This may seem rather odd, but could you tell me where we are? And what year it is?"
