"You've already told me I won't escape punishment, so I reckon I might as well make it worth my while." The Doctor started to unbutton the Master's shirt, given he didn't actually have a knife with him, but then something occurred to him and he stopped, looking around searchingly. Finally he settled on one of the pillows and he pulled off the pillowcase, rolling it up as he approached the Master again. He wrapped it around his head, making sure the cloth covered his eyes completely. Better.

He flicked the Master's nose after having tied the makeshift blindfold off and then he continued on with unbuttoning his shirt, until he could finally step back and pull out his screwdriver, using just the very tip, cool metal that it was, to draw a line down the middle of the Master's chest. That should be enough to fool someone who expected a knife.

"Do gods bleed?"
