The Master growled without realising he was because it annoyed him to see that freak touching the Doctor. His Doctor. Almost baring his teeth, the Master tugged against the handcuffs, wishing he'd managed to get that screwdriver without being seen. These two were determined to annoy him to the brink of insanity. Which maybe too late given his mental state.

"Like to see you get close enough to tie it," the Master threatened as he pushed himself onto his feet, trying to stand up before they advanced. It'd be easier standing, he could kick more that way. And get a better aim. Plus no one could sit on his legs. "Come on freak, see how well and how fast you can tie a knot."
