That rather passionate declaration of ownership just had the Doctor raise his eyebrows. No use arguing that point, especially not while his back was still raw and also because he supposed according to Roman law the Master wasn't really wrong, as such. But it was a bit of an echo anyway, things so similar to what Koschei might have said once upon a time. He wondered how the Master would feel about this part when he remembered.

"Thank you. That's very kind of you, Master." And his sarcasm was just about undetectable. "Is there nothing you want to do apart from owning and ruling?"
