Oh, now they were getting somewhere. Actually engaged with him rather then lashing out randomly. Good.
He didn't let go, and answered, "Yes, Master," without the faintest trace of mockery.
He did realize that he'd probably have to avoid his TARDIS a bit until the bruises faded. His Master been amazingly understanding about the Doctor's last encounter with this one, even thought it was funny. The Doctor had a feeling he wouldn't be as understanding of this scene, even if the Doctor was literally asking for it. His Master would react with some sort of projected visceral self-loathing, more likely. And possibly take this one's head off.
