It's The End Of The World As We Know It

A small white light appeared approximately seven feet off the ground. The metallic whir of the TARDIS's engines became louder and louder, the large blue box materializing from nothingness on the desolate Boston street. The engine thunked once more and the small box went quiet.

Inside the Control Room the Doctor was walking around the large circular panel, flicking a switch and pushing a button there. He was dressed in a full blue suit with small red pinstripes and red trainers. Just as he went to hit the final button, the monitor jutting out from the center column of the TARDIS flashed red and beep several times. It was an alert of some kind.

The Doctor sprung into action, taking out his glasses and spinning the screen to face him.

"A rift," he quirked his eyebrow. "A rift being contained by..."

His eyes went wide and punched a few buttons on the panel in front of him.

"A rift this size could take out the planet," he looked up, expecting too see Donna Noble, his previous companion. She wasn't there, then the Doctor realized he was talking to himself.

He took his specs off and ran to the doors of the TARDIS, grabbed his coat and stepped outside, on to an Earth unknown to him. He was surrounded by rubble,of a building he had never seen before. He looked around and realized that there was no more Boston, and that something had seriously gone wrong if the rift destroyed an entire city.

The Doctor closed the blue wooden door of his spaceship and looked back to the ruins of the city.

"If there is a rift...Torchwood is bound to be here," he said to himself, then took off towards what was left of downtown Boston.
