The Doctor spent some time hopping on one foot and rubbing the other, but he had no time to focus on that considerable pain - had the Master broken one of his toes? - when someone else was dealing with something much worse. "Do you ever stop to consider that I might have done something since academy days? I actually have a doctorate. A couple of them. Granted, I didn't always graduate in the right century, but I did study. Now let me take this out before you make it any worse."

He held out a hand but stayed where he was, since he didn't want to get stomped on again in case the Master still didn't trust him. He did however look at Jack and arch an eyebrow. Alright, so he'd just been killed by the Time Lord, but this wasn't how one was the bigger man.
