After a motorbike ride, the Doctor and Natalie stood at Big Ben.
They reached the top of the clock tower and were in a massive place stuffed with the clock`s mechanisms and a bell from the center of the room. Standing there was a thin-faced young man with ginger hair in dark grey suit and black necktie, covered by a caped greatcoat.
"Ah, my dear Doctor, you regenerated? ..You are becoming younger all the time! You brought your little 'girlfriend' too!" the man began with a charismatic, only dastardly voice.
"Master...the Time War after all this? You are becoming old." The Doctor responded, thinking about all the past enemies he defeated. Natalie only silently glared at the Master.
"Oh, dear Doctor, you do not know of what 'weapon' is inside this primitive clock tower. Observe." the Master reached out into what appeared to be an invisible compartment in the air. "This, is a chrono-rift in space-time. Only the presence of two Time Lords and a Tardis could open it. Observe.
The Master pulled his hand backwards out of the invisible compartment came a glowing silver sphere. "This is the Overtime Sphere, created from the knowledge of the fallen Gallifrey itself! When activated, the space-time continuum will erase Britain from existence itself! Oh, since Britain has and will be a fixed point in Earth`s history, time-paradoxes would appear in the aftereffect, destroying Earth itself! Quite an ingenious, eh?" the Master asked.
"Listen, Master. Please - " The Doctor began.
"My, Doctor. This war between us has continued for eternity!" the Master continued. "On this day, it finally ends! You are ever the madman, traveling around space-time only I think it is only because you are a corrupt, lonely existence on the inside! You are a being with a shadowy history, like me too! I have - wait, where is the pretty little companion of yours?"
"Hey." someone from behind the Master muttered. "Master...who?"
The Master whirled around only to be smashed in the face by a long metal rod wielded by Natalie, who had sneaked behind the Master when he was looking at the Doctor.
"Natalie! I was about to do something clever!" the Doctor ran to grab the sphere.
"At least I ended this!" Natalie responded.
"Oh, this is bad." the Doctor studied the ancient Gallifreyan symbols etched onto the sphere, his mind going into overdrive.
"What?"
"The sphere too is activated by the presence of two Time Lords and a Tardis. I couldn`t stop it in time when I don`t have my sonic screwdriver. It will create a space-time rip in about...a little bit. "
"Couldn`t you return it into the chrono-rift?" she asked.
"No, the chrono-rift would not be able to contain sphere`s explosion."
"What about the Tardis?"
"No time, there is no other - " the Doctor stopped. "Natalie, you are a genius!"
"What?"
"Knowing the Master, he landed his Tardis by him as an escape. The sphere could only continue its activation in the immediate presence of two Time Lords and a Tardis for the users can run away in time. All we have to do is to send his Tardis somewhere else and the sphere will deactivate!"
"Ah...where is his Tardis?"
"It`s in disguise somewhere inside the clock-tower...look, the wooden shed over there! "
The Doctor ran over. "Vortex energy is in its presence...Natalie, bring the Master over, would you?"
Natalie brought the Master to his Tardis by his necktie.
The Doctor grabbed the Master`s hands. "All Tardises have an isomorphic security lock, therefore the Tardis doors could only open by the Master himself." The Doctor made the unconscious Master push the wooden shed open.
"There we go...Natalie, wait with the Master and make sure he doesn`t awaken."
The Doctor went into the wooden shed only a moment later, walked out with the Master`s Tardis dematerializing behind him. The Doctor looked at the deactivated Overtime Sphere again. "Excellent! The Master`s Tardis is dematerializing at an unknown destination in space-time..." the Doctor pocketed the sphere.
"What should we do about you, Mister Master...?"
The Doctor promised Natalie he will make sure the Master will be taken to a place where he will never harm anyone ever again.
Natalie stood by the Doctor, holding her metal rod to make sure the Master would not try anything.
"Ahhh..." the disarmed Master groaned as he opened his eyes. "You...defeated me once more, eh?"
"This is all over, Master," the Doctor responded calmly. "I`m taking you away."
"My dear Doctor, this is only the beginning...although the universe will be at its end." the Master leaped up and ran to the place where the invisible Chrono-rift was to pull out a vortex manipulator and a golden sonic screwdriver.
Natalie ran forward with her iron rod. "Natalie wait!" the Doctor screamed. The Master pointed his "sonic screwdriver" at Natalie and sent her flying backwards in a flash of light.
"Natalie!" the Doctor screamed. whirling towards the Master. The Oncoming Storm was unleashed. "You..."
"Oh, do calm down Doctor, I only knocked her unconscious as a farewell present to you. I knew you were going to defeat me and hid a vortex manipulator and my laser screwdriver in the Chrono-rift." the Master explained. "This regeneration you still are ever the madman! It will be glorious when you are finally defeated. You fate...is sealed!"
The Master pointed his laser screwdriver at the man. The Doctor was too late to respond and was shot in his scarf, falling onto the ground. "Ah, I missed...good-bye!" the Master muttered in a child-like voice before disappearing using the vortex-manipulator.
The Doctor hesitated, remembering what happened.
The laser blast almost forced him to regenerate once more.
He had inspected his scarf earlier. There appeared to be no damage after the laser screwdriver affected it. The only sign something had ever happened to the scarf was that there were more Gallifreyan symbols floating on the scarf`s fabric.
It was like the Master had missed the Doctor before retreating once more...
