He wanted to stay longer, to make the Doctor writhe and scream... but he couldn't. He wasn't allowed. That burning resentment returned to his expression as soon as Sobek turned his back. It was one thing to wait-- it was another to be commanded to wait. And yet another to be corrected in front of the Doctor.

It was humiliation or death, and for a moment the Master hung back. When the guards prodded him forward, though, he followed suit reluctantly, trailing behind Sobek but his eyes hungry and fixed on the Doctor as he exited the chamber.
