He was an immensely patient man.
The incarnation started out with a lot of impatience. Running around, causing trouble, saving the world. He'd learned patience through the victories he'd acquired. He'd learned to get what he wanted by waiting. Starving people out, taking choices away from others. He waited this long to gain this much of the universe, and he would acquire the rest of it through patience as well.
That being said, the Master was trying his patience.
A week ago, he'd brought the Master back. Now, he was about to land on one of his worlds and the Master was still not giving in.
This was really unacceptable. Didn't he know who he belonged to?
He picked up the communicator and spoke into the system.
"We're arriving," he said. "I've placed a suit in the main bay, you should wear it."
