"I think that's disconcerting personally," the Master mused, still tilting back in his chair on those two legs, eyes on the Doctor. He didn't focus on Jack, he didn't even want to look at the freak. He was annoyed enough as it was that Jack was describing a regeneration he didn't know. What an annoying little fact, a regeneration he didn't know. Rude.

"That you're not grumpy, I mean. You're usually grumpy. In my experience, when you're not grumpy and you seem so nice and pleasant, it means you're on the verge of a break down," the Master wasn't really set on this theory but he had pretty good evidence to support it. Plus he had a funny feeling that analysing the Doctor would piss either him or Jack off and that was just a picnic for him. "Then hell hath no fury when you lose your shit. I remember it with the fourth one of yours. Remember, big scarf, creepy grin? Seemed so nice and yet you were such a horrible creature inside."

Then, thoughtfully, he let his head roll back with a sigh. "I can't wait to see what happens when you snap. It'll be more fun than ice-cream and forgiveness."
