The Doctor stood before the Master, he listened to the other Time Lord's voice and soon a smirk curled upon his own lips "Surprised?" the smirk widened as he stepped near the other Time Lord "That I could be dying one minute and just fine the next" when the sonic laser was pointed at him and its rays hitting him the Doctor winced and did his best to block out the pain which actually was quite successful this time around. Deciding to play along the Doctor gave a groan and buckled at his knees purposely. Which he knew all too well it would really annoy the Master after the man would realize the truth.

Hearing the Master laugh, seeing him dance around before looking at him straight in the eyes. The feeling of the Master grasping his tie and pulling him close seeing the evil smirk followed by the man's words. A few thoughts warmed through the Doctor's mind as the smirk was returned in gesture "Mm am I really?" there was a spark of curiosity within the Doctor's eyes as he kept the stern gaze upon the Master. 

Seeing the reaction hearing his growl to the Master realizing how healed the Doctor was he gave a semi-chuckle "It just bothers you doesn't it?" it seemed their moment was of 'one upping' each other in glances and comments was interrupted upon hearing Jack's voice. Only then did the Doctor turned to his friend, hearing the immortal beg then seeing him get killed the Doctor's hearts weighed heavy in his chest "You really need to stop killing him, Master" his voice was stern.

The Doctor knew what he had to do, he had to disable the Master and free Jack. He knew the immortal would find a way to his vortex manipulator and could escape. The Doctor used the closeness between himself and the Master to his advantage as he without warning gave a rather firm headbutt to the Master's head enough to catch the man off guard and knock the sonic laser out of his hand. Hearing the weapon skid across the floor the Doctor released the Master and rushed for it. Taking a hold of it he freed Jack and rushed him out of the room "Find your vortex manipulator and go" he firmly shoved the Immortal out of the room.

Slamming the door shut he turned around the face the Master the sonic laser firmly in his grasp as he pointed it toward the Master. "Looks like it's just you and me" the Doctor neared the suited man and reached out to take a hold of the man's tie and pull him close "My my … You're been quite the naughty one, Master" brown eyes stared into hazel brown hues. The Doctor knew he needed to buy time for Jack to escape so the longer he held the Master engaged in conversation or something of the sort the better. "Tsk tsk tsk. What will you do now?" 

The Doctor tauntingly waved the Master's sonic laser before the man's face as the Time Lord smirked then tucked the other Time Lord's sonic laser into his own jacket pocket beside his sonic screwdriver but didn't release the man's tie "Without your weapon we're equally matched, yeah?" the Doctor smirked and gave the Master a wink before releasing him all together as he stepped back. "Have at me, Master"
