The Doctor cries out as the Master's sword hits him in the side. He backs up and tosses his suit jacket away, freeing up his arms and showing off the lovely red mark where the Master just hit.

"I wouldn't dare," he says in return. "You're always really tetchy when you fail."

He throws another few slashes in the Master's direction, then follows it up with a kick towards his knee, to try to knock him off balance.
