The Doctor parked the TARDIS a safe distance between the Andromeda and Umbra galaxies, sat down, and spun in his chair. He looked around the silent room blankly. Once again, he found himself alone.
It's the curse of the time lords. Your friends will grow up, move on, and eventually die, but you? You'll be right back where you started.
He planted his right foot down on the floor and pushed, spinning the chair again. He started off slowly, but sped up until he could no longer differentiate between the lights on the walls and the wall itself; it was all a spinning blur of flashes, lights, buttons, levers, and loneliness.
It wasn't in his nature to be mopey, though. The Doctor stopped the chair, stood up, and immediately fell over. He jumped up and bounded down the stairs.
"Well then," he said out loud. He liked talking to the TARDIS, even though she couldn't respond. Another lost friend, but there was no time for that. He walked in a circle around the center of the TARDIS.
"Where to next? Next, next, next … I have all of time and space at my fingertips. The world is my oyster. Life is a box of chocolates. Plenty of fish in the sea. Stop to smell the roses. Never swim right after eating … What?"
He dashed up the stairs and vaulted himself over the railing. He pushed random buttons on the control panel without looking, and then pulled the nearest lever.
"To infinity … and beyond!" he shouted as the TARDIS shook. "Oh, that was bad. That's not my catch phrase. I need a catch phrase. Why don't I have a catch phrase? I need-"
The TARDIS stopped suddenly, and he was thrown against the railing. The Doctor got up, straightened his bow tie, and strode out the door.
He was on earth. The weather was cloudy, and he thought for a moment he had landed in England in the 21st century. There was something vaguely different about the place, though. He looked around - and noticed the girl. Her hair wasn't unlike that of Amy Pond, and she was staring open mouthed at the box that fell out of the sky and the man that walked out of it.
She screamed.
