The Master's body tensed at the threat, his body almost trembling at the idea of suffering that again, he really didn't want to. When nothing happened, a relieved half laugh ripped out, though there was no humour to it. The absolute bastard, he was playing head games with him! He thought this whole thing was some joke. Recoiling at the flick, he gritted his teeth, just hoping that if he didn't do anything to provoke a reaction, the Doctor leave.

He had to get bored eventually. The Master would have time, he'd have chance to fix on an escape plan. He couldn't take much more of this.
