The Master growled when he realized the Doctor wasn't really in pain, He had been getting ready to strike him until he lost his screwdriver, He noticed the Doctor had freed Jack as well. Jack fell to his knees and was panting, He was shaking "Doctor please don't," he was begging, he didn't want The Master to kill the Doctor, Jack couldn't die but he knew that the Doctor could if killed before he could regenerate. Jack saw that the Doctor wasn't giving him a choice when he was rushed out of the room, he sighed and went to find his vortex manipulator and left, hoping the Doctor would be ok.

"Give it up Doctor," The Master sneered "You will never win." He knew that he needed to hurt the Doctor till he had broken him. He smirked when a message came through confirming Martha Jones dead. "Told you," he said smugly. He was hoping either that would anger or break the Doctor, he knew it would have been easy to break the Doctor if it had been somebody like Rose, but the Master couldn't get his hands on her "Your friend is dead, mind you losing her won't break you as much as if it was Rose, " he laughed darkly "But I am sure it will still get to you in some way." He wanted to make sure that the Doctor suffered in many ways as he possibly could. It was all a very entertaining game for the Master.

The Master smirked and when the Doctor told him to come at him he laughed "With pleasure." he attempted to push the Doctor up against a wall and he punched him. He knew he could wear the Doctor down eventually. "For letting go one of my prisons I was going to use to break you, You will suffer," He continued to fight him and he looked crazy and rather annoyed.
"Well suppose It has always come down to you and me in the end, Though difference is , You won't stop me, and I will break you," He wanted the Doctor to loose hope. He knew that the Doctor often had a lot of that.

The Master started singing I can't Decide and danced around him, before being rather rough and slapping his face. "What gives you so much hope mmm,? How can you have so much hope when I bet you down." He laughed "We were never evenly matched, I was always better than you Doctor," he spat, He refused to even believe they had been friends once.
"Things will never go back to the way they were at the Academy, Once I am done, I will leave you broken and hurt, You think I will stop and tend to you, like when we were young and had gotten into a little argument that went too far!! I Have changed, I can't believe I ever did care about you." He missed those days but he wouldn't admit it, He then kneed the Doctor right in the stomach.

The Master laughed evilly and made sure that he was going to make sure the Doctor suffer, he lunged at him attempting to grab his laser screwdriver from the Doctor's pocket, there was a crazed look in his eyes.
"Give it to me," he hissed, he knew that the Doctor knew that he could do a lot of damage with it, He was determined that he was going to break the Doctor, He chuckled darkly. "So whats it going to be Doctor, because you know one day I will get bored and kill you."

He knew that one day might happen, though right now, he didn't want to, he was looking rather displeased that he didn't have his laser screwdriver and he sighed. He was laughing more, he sounded crazy as he laughed, he though stopped and held his head as the drumming in his head got louder and more annoying, he clutched his head in pain and this time yelled out in pain, He was unable to to focus for awhile, he closed his eyes tightly and he didn't know if he would ever be free of the drumbeat in his head, he panted a bit. "See it, will never end."
