A/N: Thanks for the great reviews! Sorry this chapter is so short, and probably not up to scratch but I really wanted to get it uploaded before I go on holiday, which is tomorrow at 5am -collapses- How I'm going to survive getting up at like 3:30am is a mystery, but oh well.

Tai Greywing- The weirdest thing about me 'predicting' that end scene of Doomsday is that I've been freaking my friends out quite a lot recently with other things like that, although not as dramatic (eg. The other day I walked into the kitchen when my mum was looking for something and just went, "there's the baking paper", and she was like how did you know I was looking for that?) Maybe I'm not human, it would explain quite a lot o.O;

Anyway thanks for the reviews again, and please keep reading!

Chapter 6

Decision Time

The Doctor dashed around the console, frantically throwing switches and pressing buttons as the TARDIS whirred away, flying bumpily through time and space. It cast an eerie green glow across the Doctor's face, showing his determination- had anyone been there to see it. He was being driven on by the thrill of an adventure, the will to save all of time and space, and his desperation to see Rose again. The whirring of the TARDIS grew stronger as he neared the Croulahrr ship, and a determined grin spread across his face. Every step he was a second closer to seeing Rose again.

He fell against the console as the TARDIS landed with a thud- perfect landing, as usual. He ran to the viewing screen and saw guards surrounding the strange blue box that had just arrived from nowhere, waiting for his appearance. Anger burned inside him as he saw Serpor stepping forwards, obviously giving the guards orders. Time for his entrance.

He threw open the door of the TARDIS and strode energetically out. The guards instantly pointed their weapons- metal rods almost like staffs that sparked at the tip with some unknown energy- at the Doctor, surrounding him. He ignored them completely, batting one away with his hand as if it were just a harmless twig, and approached Serpor. The Croulahrrs looked at each other cautiously, not knowing how to handle the Doctor's confidence.

"You opened a rift." The Doctor said simply. Serpor smiled sickeningly.

"Well done Doctor! They always did say how clever you were."

"You have no idea do you." Serpor looked at him enquiringly. "You thought you could just open a great big rift in time and space and then abandon it and everything would just be dandy?" The Doctor rose his voice, his anger seeping out. Serpor's smile twisted into a frown. "That rift is tearing apart the very fabric of reality! If you don't close it the whole of time and space will just collapse!" He yelled.

"I think not." Serpor smiled mockingly.

"You what?"

"You can't frighten us with your stories Doctor, we know you think yourself so superior to us but we are not as gullible as you presume." The Doctor took a deep breath and ran an agitated hand through his hair, attempting to control his fury.

"What would I have to gain by lying to you about this?" The Doctors voice sounded calmed and restrained, but shook with suppressed anger.

"We know that all you want is to be free of us Doctor and to have your human back." The Doctor shook his head in disbelief- he couldn't believe he was hearing this.

"Yes that's exactly what I wanted initially, but now I find myself needing to clean up the mess you've left behind as well! You have to stop this NOW!" He screamed at Serpor, losing control of his rage. Serpor merely took a step back and looked down on him pompously.

"Guards, take care of him." He said calmly, turning to walk away. The Doctor looked around in alarm- they were approaching him from all sides, trapping him. He felt a sharp object being forced into his back, and cried out in agony as a current ran through his body. He fell to the floor, unable to balance as the world around him swayed and blurred, gradually fading away to blackness.

xoxoxoxoxo

The Doctor stirred awake, pain coursing through his body. The cold floor against his face brought him to his senses, and he slowly sat up as the pain subsided. For a moment he couldn't think where he was and why, or even who he was. He panicked as it all suddenly came rushing back like someone had just hit him hard around the head, and he remembered the rift, Serpor's arrogance and Rose trapped beyond his reach.

Questions raced through his mind. How long had he been out? Where was he? Was Rose safe? He struggled to his feet, falling onto the wall for support in his hurry. He was in a prison again, much like the one he had first been placed in. What made them think they would be able to contain him this time?

He reached for his sonic screwdriver, and held it to the lock. The screwdriver whirred away, but nothing happened. No satisfying clunk of a lock opening this time. So that was their game. The door must be dead lock sealed- his sonic screwdriver was useless. He looked around the room. Four walls of concrete. Great. He leant back on the wall, thinking deeply. There had to be a way out of here, surely.

He ran through various past experiences he'd had of being locked in a prison. Scanning through his memories, he became distracted; Rose's tearstained face when he had seen her stranded in that parallel world kept creeping into his vision, haunting him. He sank to the floor, holding his head in his hands. He had to get back to her, he just had to. Being in the TARDIS without her around was so lonely, he had gotten used to her company too well. He didn't want to be alone again. Not anymore.

His mind drifted through memories of time he had spent with her; travelling to 2012 and seeing the Olympics, coming face to face with a werewolf, defeating gas mask zombies. His eyes lit up suddenly as a thought occurred to him, and he took out his sonic screwdriver once more- maybe it wasn't so useless.

He walked up to the heavy door and examined the concrete around the lock. He tapped it firmly with his knuckles, testing it's strength. A broad grin spread across his face; the concrete was only thin. That time they had been trapped in a room by the dead little boy with a gas mask fused to his face, he'd tried to set up a resonation pattern to loosen the concrete around the bars that had been on the window. If he could just do that around the lock…

He held the screwdriver up to the wall, fiddling with it until he found the correct frequency before holding it against the wall surrounding the lock. Once more thoughts raced through his mind as he waited for it to take effect- how long had it been? How was he going to close the rift? Would he have enough time to save Rose? After painstaking minutes that seemed to stretch out into hours the concrete around the lock suddenly crumbled and gave way, releasing the lock. The Doctor heaved his shoulder against the door, and it slowly swung open. He grinned- another step closer to Rose.

He ran swiftly down the corridors, barely making a sound until he came across another control panel. Hacking into it this time was also more difficult- they really had learnt. They may have been overly confident in themselves, but it seemed he had also presumed too little of them. A voice at the back of his mind nagged him constantly, 'you've been too long, you're running out of time.' He shook his head irritably, silencing the voice.

Once he had successfully gained access into the control panel, he scanned through a map of the ship, pausing when he found a room that looked promising. Bringing information onscreen he breathed a sigh of relief- he'd found it. The control room for maintaining the rift was located at the far side of the ship. Once more ignoring the voice inside his head he dashed off, frustrated that he couldn't run any faster.

As he rounded a corner he suddenly leapt back, pressing himself against the wall so as not to be seen. He held his breath as a Croulahrr guard strode casually past, not really paying attention. The Doctor breathed a sigh of relief as the guard carried on, not turning down the corridor he was hiding in.

After some time navigating the endless corridors and avoiding guards, he finally reached his destination, gasping for air. But he didn't have time to stop and catch his breath. He quickly opened the door and slipped inside the dark room. It seemed abandoned, the only lights where from the slight glow of the controls. He scrabbled around for a light switch, blinking as the room lit up.

The room basically consisted of a wide control panel and a large screen. The Doctor walked cautiously forward, hands in pockets. He stared up at the screen; it showed deep space- he made a mental note of the co-ordinates shown- just a random stretch of black dusted with stars and galaxies, but with a huge tear down the middle. It was as if someone had just carelessly slashed time and space right open. The Doctor frowned at it, thinking of how Rose must have been thrown through that hole in the universe without a second thought, and how it was now slowly destroying the world she was trapped in, soon to start on others.

He glanced across the various buttons and levers- it seemed so impossible to achieve yet relatively simple to work. 'It must be using an immense amount of power to sustain this rift,' he thought to himself, instinctively throwing switches and pressing buttons. After some sufficient tinkering with the controls he stopped. He stood upright and sighed wearily. He stared at one particular button.

Just one button. Just an insignificant press of that little button that blinked red on and off. That's all it would take to close the rift. Once it was done that huge tear in space that was shown on the screen before him would gradually repair itself, sealing the hole. Once that was done he would never be able to cross through into that parallel world again.

He would never be able to reach Rose.

But he did have a chance. The rift would take time to heal, although maybe not long. If his calculations were correct then he would have just enough time to dash through that hole, grab Rose and leave again. That was if he was lucky, and if he didn't waste a fraction of a second.

But could he risk it? Could he risk never being able to see her again? Could he risk breaking his promise to her and failing to rescue her? He rubbed his face with his hands. He knew the decision had already been made, and that in reality he didn't have a choice. If he didn't heal the rift now it would grow beyond control and the chances of either of them surviving if that happened were next to nothing anyway.

He took a deep breath. He had to have faith in himself, and in Rose. Before he even realised what he'd done, he'd pressed that not so insignificant little button and fled from the room.

A/N: Sorry that was a short chapter, but that's where I wanted to end it, and sorry if it wasn't up to scratch as well. I think there's only a couple of chapters left cause it's coming to the climax now, but you never know :D So please keep reading and review!
