"The Master, much like most terror in the universe, operates on chaos and discord. He's a timelord as well. We were at the academy together. He was a brilliant mind, and often was the top at his class. But he strove for more. Instead of being an observer, he wanted a more hands on experience. Now he prefers the unexpected backstab to the organized beauty. I pity any man who has the unfortunate circumstance to be tossed across his path."
The Doctor shook his head in a small motion of despair (causing his curly mug to lightly breeze around), and looked around the cabin. He took a look at the control panel, which was now covered in a light layer of dust and cobwebs. He looked closer at the flight computer, all of the controls, and even the pilot's chair. Nothing seemed to stick out at the Doctor...that was until he stood up sharply, and turned his head with panic towards Shauna.
"Shauna...take a look at this cabin....is there something funny about this place?" While she looked around, he waited for an answer, but was too anxious to wait for an answer. "Take a look at the number of bodies in here. Then take a look at the number of chairs....."
There were indeed five chairs, each fulfilling it's purpose in a typical starship: the navigator, the captain, etc. And indeed, there were corpses in the chairs. Four of them. Four corpses.....five chairs....
