Sorry it's taken to long to update, I've recently had exams and that took up all my spare time. Anywayz, I hope you enjoy the final instalment of 'The Reunion'. Have fun!

"Ok! Everything's set! Switch the realities in three…two…one…mark!"

The Doctor pressed his ears closer to the side of the shaft.

"What's happening?" Rose asked, following his example.

"They're switching realities." Replied the Doctor, his eyebrows furrowed in concentration.

"Begin harvesting the energy!"

Large sounds of crunching machinery and the humming of computers could be heard through the wall. Rose remained determined to listen, and discover what she could. She may not understand now, but she will, and soon. Rose laughed silently to herself. Her experience as a senior agent of Torchwood had enhanced her senses, increased her curiosity and desire to understand everything and anything. She had faced various challenges, but nothing had really come close to the thrill of travelling with the Doctor.

Rose's bright brown eyes lit up. The Doctor landed here, inside the chamber in which they were swapping realities. He was swapped into the other reality, where he met me, and now he's come back. He wants to stop the swapping of realities, but that would mean…

"I won't be able to get back to the other reality, will I Doctor?" It was barely a whisper, but the Doctor would have heard it a mile away.

He remained silent, his eyes avoiding Rose's.

"No. You won't." He looked up at Rose, forgetting to listen to what was happening in the lab.

"I was serious when I said you couldn't come back."

His eyes suddenly dulled.

"You're having second thoughts, aren't you?" The Doctor's glum expression made Rose's heart ache.

Rose moved closer to the Doctor and cupped his head in her hands. She looked into his eyes, and he looked into hers. She smiled at him.

"I could never, ever, have second thoughts about travelling with you."

The spark in the Doctor's eyes Rose remembered suddenly glowed again.

"I have waited over two years for this chance, and nothing will ever take this away from me."

Rose sighed as she looked at the man with whom she was so deeply in love.

"I made my choice a long time ago that I was never going to leave you."

Rose smiled and gently brushed her lips against the Doctor's. He responded in kind. For a few seconds they immersed themselves in just those precious moments they were sharing. Rose suddenly pulled back from the kiss. The Doctor quickly thought something was wrong, and then he noticed Rose's grin.

"What is it?" He asked, curious to know what was so funny.

"Oh it's just that…Jackie would love this excuse. Mum! I can't come back because I might destroy the universe with an invasion of exotic particles from another universe!" Rose giggled at the thought of what Jackie Tyler would say if she had heard that now.

The Doctor grinned, and for a second, just a second, Rose thought she could see all the hardships and sufferings he had gone through disappear. Perhaps now he had finally moved on… but it was only for a second. The deepness and age in the Doctor's eyes returned. Rose sighed. She knew in her heart that he would never recover from what he had experienced, but she hoped that if they were together, he would be able to, not move on, but remember the good things that had happened, and look forward to a great future that they could share with each other.

Rose was rudely awakened from her thoughts as an ominous blaring of an alarm sounded through the wall of the shaft from the lab. The Doctor's eyes lit up and he pressed his ear to the side of the shaft, desperate to hear what was happening. Rose prepared herself for whatever might happen.

"Quick! Turn it down!" A scientist bellowed at the top of his lungs.

The alarm did not cease, and the rumblings of machines grew louder. The Doctor's expression grew worried. Rose knew what he was thinking. If he barged in and stopped the machines he would save them, but it would risk capture, and who knows what would happen if the commander got his hands on his Rose again? Use her to weasel information out of the Doctor?

"I can't! The power build up isn't stopping! The exotic particles are exerting themselves in both universes!"

That was all the Doctor needed to hear. With a mighty crash, Rose and the Doctor tumbled out of the shaft and into the science lab. The several scientists in the room stared in shock.

The Doctor jumped up and launched himself at the nearest console and whipped out the sonic screwdriver.

"What are you doing!?" Cried the scientist next to him.

"Quick! Stop him!" The head scientist pointed at the Doctor, signalling for the other scientists to arrest him.

"NO!" Screamed Rose, jumping in the path of the scientists headed towards the Doctor. The scientists paused in confusion, unsure of whether or not to proceed against the blonde girl.

"He's HELPING you!" Rose screamed, but it was barely audible above the other shouts from scientists, the grumbling of the machines and the blaring of the alarm. Rose turned around to the Doctor, racing to his side, though unsure what she could do to help.

The Doctor was pulling and prodding countless levers, sweat increasing on his brow. The sonic screwdriver was in overdrive. The Doctor was typing and trying to re-configure so fast that his hands began to blur. Various scientists noticed what he was trying to do, and began to help.

Despite their best efforts, the reality chamber was becoming electrified. Rose could see with her bare eyes the static forming around it. The scientists and the Doctor noticed as well. They stepped up their efforts.

"WHAT THE BLOODY HELL…?" The Commander stormed in, his face red with frustration.

He took one look at the reality chamber, and all the red in his face quickly turned to white.

Slowly, the static began to subsidise. Rose suddenly realised how hard her heart was beating. She took a deep breath and closed her eyes in relief. Opening her eyes, she quickly turned her attention to the Doctor, who stood behind one of the machines, his face expressionless.

He looked up to meet her gaze. Rose's eyes lit up and her mouth twisted upwards into a grin. The Doctor grinned too. Rose let a laugh escape her lips as the Doctor scooped her up in a big hug. She wrapped her arms around him and laughed some more. The Doctor was grinning.

"Excuse me?"

The Doctor and Rose tore apart from their embrace and turned to face the commander, who stood in the doorway, he face white with fear and confusion.

"What happened here?" The commander waved his arms around pointing to the various bits of materials that were floating around the room.

"Well…" The Doctor started.

"He saved us."

A small voice from the back of the room spoke out. All eyes turned to face one of the scientists who had been working on the reality chamber. He shifted uncomfortably when he realised that everyone was waiting for him to continue.

"He saved you?" The commander looked at the man in confusion.

"He stopped the particles from inflicting damage on both universes."

"He did now?" The commander looked from the scientist to the Doctor and laughed.

"He did." This time, another scientist spoke up.

The head scientist suddenly marched forward to look the commander in the eye.

"He saved everyone, including your sorry arse."

Rose could barely contain a giggle when she looked at the commander. By the expression he was wearing now, it looked like he had never been spoken to like that in a long time.

"I will not be-"

"No! You will listen to me this time. I'm shutting this programme down now." The head scientist glared at the commander with a gaze that even made Rose shiver in fear.

"You don't have the authority!"

"Oh yes I do…"

"What should we do?" She whispered.

The Doctor leaned closer to her.

"Enjoy the show." He winked and turned back to the head scientist and the commander, who were still exchanging pleasantries.

Rose smiled. Travelling with the Doctor was really the stuff of legend.

OO

"Where to now?" Rose asked as she bounded around the TARDIS to the Doctor, who sat quite comfortably in the jump seat.

After the commander had been forced to step down and the reality programme shut off; the Doctor and Rose were thanked for all their help in once again saving the universe(s). After a quick goodbye, they jumped back in the TARDIS, ready for their next adventure.

"Oh, I was thinking of taking you to see the light show on the planet Polofima, it's absolutely amazing…" And then he was off again, talking at a million miles per hour.

Rose just smiled. After all, who'd want to miss the lights?
