The Master looked both left and right, pulled a face of annoyance, then gestured right. It was on the Doctor's side so he'd have to go first and besides, it was probably the safer option, he was sure the noise came from the left... right? It had to of. Maybe. He didn't even remember, he just knew he wanted to leave.

"I haven't seen any cameras or anything. If I had, I would of mentioned them. What with them seeming important and all."

He really wished the Doctor wouldn't ask him dumb questions like that, it was just embarrassing. "Look, just go right and we'll see what happens. There has to be an exit somewhere. Or at least something more than tunnels. And if there's a monster or a giant robot banshee, I'm sure you can handle in."

He, on the other hand, will be happily running away.
