Author's Note: Quite a speedy update. Didn't expect to update so fast, but I felt that I might as well continue writing. So I apparently ended up finishing this one too. And that brings us really close to the end. Like a 'couple of chapters' close. So the light at the end is arriving. So guys, please enjoy, and please review!

Note: The Reference Frame Implosion is partly my own creation. It is based off to what happens in the minisode Time Crash, except there are no TARDISes crashing. Any resemblance to anything else from Doctor Who or another fanfic is purely coincidental.

George's TARDIS.

Getting a Metebelis III crystal wasn't the hard part. It was what they were about to do with it.

George typed a number into the keypad next to one of the corridor doors. "What we're about to do is irreversible. I'll probably be the stupidest person in existence for asking this question, but do any of you want to turn back?"

Everyone rolled their eyes at him.

"Right. Thought as much."

He led them down the corridor into a room with an extremely large cylindrical chamber in it.

"What's that?"

George sighed. "It's a modified Extraction Chamber. One of the original uses of an Extraction Chamber was to force regeneration for…well let's just say the outcome wasn't very nice. This modified one will help us track the Doctor by tracking his regenerations through time."

"How?" Amy asked.

"It's complicated."

Martha chuckled. "We've been with the Doctor, I don't think anything could be more complicated than the Doctor."

George shrugged. They had a point.

"The Ghost Drive helped us track the keys. The Extraction Chamber, combined with the TARDIS Navigation System can help us track different incarnations of the Doctor. When we reach his current incarnation, we can extrapolate our function to find a theoretical position based on his previous destinations. Since he won't be at any of them, we use the worm in his TARDIS telephone, to approximate a location. Once we come close enough, I can use the Metebelis III crystal and the TARDIS telepathic field to communicate with him."

"How?" Clara asked, intrigued. "I thought that was only for navigation."

"Not the membrane. The field that actually permeates Time and Space and helps you translate languages, for one. He'll use the Sonic Sunglasses to pick up the call and transmit his thoughts telepathically, and I'll use the worm to transmit my voice. We'll get the co-ordinates from there. To be safe, we'll have to assume that's all he'll have time for, before they come to check on him. Naturally, I'm already on to it."

"What about getting into the Time Lock?" River asked.

"One thing at a time, guys. One thing at a time."

Missy confronted George. "Rule 263 of Battle Tactics 101, don't antagonise the rescue team. What are you doing, George? I don't know what you're up to, but it won't end well."

George tried to come up with something to say, but for the first time, Koschei was making a point from the 'Good' point of view. He sighed. "I have trust issues. I trusted someone too well once. You probably know the story better than I do."

Missy nodded. She did. But… "That was more than two millennia ago, George. A lot has happened since then. "

"You're right. I hate saying it, but you're right."

Just as George moved to have the conversation with the Doctor as scheduled (everyone else would be there in a minute),River entered the Console Room, trembling to the core.

"River, what's wrong?!"

River looked at George, pure terror plastered all over her face. "I figured out who they have in custody. It's her. The only one unaccounted for."

The Ship of the Silence, the Seventeenth Cluster, Mutter's Spiral.

The Doctor sat silently with his Sonic on. The GHOST Drive. Had to be. The TARDIS phone had been ringing all this time, but silently after the first 12 rings. Clever. A worm inserted into the TARDIS mainframe. Only way they could contact him. But…

He shook his head. Only way out. He switched the Sonic to silent mode and accepted the call.

Back on the TARDIS George jumped in alarm as the v-board behind him beeped suddenly. "He's on!" George shouted, as he plunged his hands into the membranous tissue, prompting everyone to rush into the Console Room from the various corridors. "Hello."

"Ah. George. Hello again. How's everything?"

"Everything's fine. Everyone's fine."

"How did you call?"

"Inserted a worm into your TARDIS before you stole it, so that it would ring the exact second I wanted it to. Then I calculated where you would be when it rung. I assumed you wouldn't pick it up on the first ring, so…"

"Smart."

"Not really. You would have thought it up."

The Doctor's voice suddenly took on a hard tone. "How do you know me? Who are you really? You would have to have been there in the Academy because you know my name. You managed to convince three of my companions whom I consider inconvincible. You play with Time as if it's yours to play with. You seem to know every other thing about me, but I know nothing about you. You have an unparalleled arrogance, but also one of the softest demeanours I have ever seen. You can't be me, or the Blinovitch Limitation affect inside the Time Stop on Nonazon, seeing how delicate Time Stops are, would have blown the field to bits. I know one thing though…"

"And that thing is irrelevant, Doctor. We're trying to save you."

"Well I don't want you to!"

"Why not?"

"BECAUSE YOU CAN'T! Because you don't understand. Battle Tactics 101, rule 17, don't walk into the Janus trap."

George sighed. "Of course. To be expected."

"Duh! Explain to the others what a Janus trap is and why I can't have you save me."

Jack raised an eyebrow. "What does he mean, George?"

"A Janus trap. The Janus is a two headed species, one at the back and one at the front, the female of which can see into the past with one and into the future with the other. The Janus trap isn't related to it except by the two headed bit. A Janus Trap basically ensures that an abducted person will not escape. You ensure that the abducted person is abducted by one person who he or she holds dear, while another goes around looking for him. If both the captured and the searching party are then led to the same place, well…you get the Janus trap. Neither the past or the future will save you."

"I told you. There's no point. There's no way you'll find me either. I scrambled the co-ordinate search system just a few seconds ago."

George chuckled. "You were right about one thing, Theta. You don't know me at all. Do you think I'd waste my time leaving such a simple worm in the TARDIS mainframe?"

"What do you mean?"

George pressed a button on his TARDIS's main v-board. Back on the other side of the call, the Cloister Bell rung.

"WHAT HAVE YOU DONE?"

"I initiated a Reference Frame Implosion for T-minus 120 minutes, which means that in 2 hours, the ship you're in is going to be part of a Black Hole. The only way I'm going to cancel the implosion is if you give me the co-ordinates of the ship."

"You wouldn't."

"No, Theta. You wouldn't."

He shut down the call, but didn't switch off the worm broadcast. The Doctor could call them back if he wanted to.

Everyone around George was in shock. Rose was the one to break out first. "This is what you meant by irreversible. If he doesn't agree, the ship becomes a Black Hole."

"He will."

"And what if he doesn't?"

"Then we use the co-ordinates from the call to find him."

"He said he scrambled them."

"He did. But Block Transfer Computation scrambling doesn't work quite the same way. He needs a Base Code to scramble it from. I implanted the number 2 in his mind. Now all we have to do is rewire it through the inverse and we get the original code, and therefore the co-ordinates."

"That is it?"

"Yup. Get some sleep, guys. This is the real Deus Ex Machina."

George's TARDIS.

Intruder Alert! Intruder Alert!

George jumped out of bed. Intruder Alert?

He picked up his Alpha Meson blaster from its gun holster next to his bed. Nobody could breach his TARDIS. He'd set the safeguards and shields to maximum, not to mention several traps around the TARDIS for unregistered biological life-forms. Unless…

…unless the intruder had always been on board. He had never taken a life-form scan since the first. Couldn't be a creature from the Vortex, so it had to be one of their enemies. He set the power setting of the blaster to maximum. He pressed the Console Room code into the code panel. He hurried in and transferred the alert code into his Sonic Screwdriver. He set the Screwdriver to the scan setting and holstered it into his gun holster. He took the blaster in his hand and typed the area code in. For some reason it seemed really familiar. He stepped in…

…and arrived right at the edge of the exterior shell. And the only things kept there were…the escape pods.

Without warning a pod opened up and someone pushed him in.

"What the hell?!"

He swung around to find John and River closing the pod doors. He slammed a palm against the doors. "What the hell do you think you're doing?! Let me out!"

John shook his head. "Can't. You know as well as I, why I can't. I figured out the way into the Time Lock. Since it has to have the same Time Trail, we use my TARDIS, which by being in proximity to yours, would have accelerated its activating process. You noticed it as soon as your TARDIS notified you about the extra weight on her. Of course, it's just nearly the same. Which is what his key is for. We use the key to create a clone copy, which we can do by using the true limits of the GHOST Drive. You made a mistake by mentioning Block Transfer Computations. We already sent everyone onto my TARDIS. We're not going to launch you. You'll just remain locked up till we leave."

"I can hack through."

"It's deadlocked. It would be useless to try."

"Why?"

"The Janus trap. You said it yourself. Two of the dearest people. We're expendable."

"NOT TO HIM! YOU ARE NOT EXPENDABLE TO HIM! If one of you dies for him, he will rip the entire universe to shreds looking for those responsible! I know what's going to happen, because it has already happened once before!"

"Better us than you."

"Not when he doesn't know who I am. It's a trap. It's called the Janus Trap for God's sake. It even has the word trap in it. No other traps are so kind."

"You don't trust us then?"

"No. I trust you too much. Each and every one of you would die for the Doctor, but you don't have a clue of what that will do to the Doctor."

"Too late." River pressed a button on her Vortex Manipulator and the two of them disappeared with a zap, leaving George alone in the pod. A half hour timer started ticking down for the deadlock, but it was too late. He could hear the sound of John's TARDIS leaving. Never had the sound of a TARDIS drained hope out of anyone. Except this once.

But one spark remained. One thing made George smiled. Now nothing held him back. Now the Universe would get to know how much damage he could do.
