DISCLAIMER: Sadly, I do not own Doctor Who, it belongs to the BBC.
Chapter 1 is set during Doomsday (Series 2 finale), when the Doctor and Rose are about to open the Void.
Chapter 1 - The Void Closes
It was time. The Cybermen were just a flight of stairs away from the Doctor and Rose, and they could see the Daleks approaching the Torchwood building they were stood in from the sky. They had to move quickly.
The Doctor passed Rose a magna-clamp, the very thing that was going to prevent her from being pulled into the Void, which would be a certain death. She rushed over to one side of the room carrying the clamp, while the Doctor headed to the other side with his own. She pressed her magna-clamp against the wall and waited for further instruction from the Doctor.
"Press the red button," he said. She quickly located the red button on the magna-clamp and activated it. Instantly, she felt it fuse against the wall.
"When it starts just hold on tight. Shouldn't be too bad for us, but the Daleks and the Cybermen are steeped in Void stuff," he said. They ran over to the two levers, ready to push them up and open the Void. "You ready?"
Rose gave him a quick nod, then noticed four Daleks parading the skies out of the window. "So are they," she said.
He wasted no time. "Let's do it!"
As quickly as she could manage, Rose forced the lever on her side up into position whilst the Doctor did the same to his.
"Online," the computer said. A piercingly bright light, which came from the end wall, filled the room. Rose leaped over to her magna-clamp, wrapping her arms around it tightly. She looked over to the Doctor to see that he was also ready. An intensely strong wind started to blow towards the light, and Rose fought against it to try and stay standing. Then, she heard a huge crash from behind as a window smashed and Daleks began flying past them, past the Doctor and Rose and into the white light, disappearing forever.
The Doctor grimaced as he tried to hold on. "The breach is open! Into the void! Ha!"
Their plan was working! Rose smiled at the Doctor, as she tried to keep flat against the wall to stay out of the way of the metal monsters that were whizzing past. Suddenly, she noticed the Doctor's face fall, and saw that he was looking at her lever. Sparks were bursting from it, before it clicked out of its upright position.
"Offline," the computer said. Rose knew that something had to be done. She unwrapped one of her arms from the magna-clamp, and reached for the lever in front of her, the forceful wind trying to drag her into the Void.
Panic was in the Doctor's eyes. "Hold on!"
She strained to reach the lever, but she couldn't quite grasp it. She let go of the magna-clamp with her other arm and took a dive for the lever. She caught it and looked over at the Doctor. He stared back at her in agony as she pulled the lever with all her strength. Finally, against all odds, it snapped back into place.
"Online and locked," came the emotionless voice of the computer as the flow of the Daleks and the Cybermen sped up. All Rose was holding was the lever, and slowly, she felt her body being lifted by the wind.
"Rose, hold on!" the Doctor said, reaching for her, even though he was on the other side of the room, not close enough to grab her. She cried out in despair as her grip on the lever loosened.
"Don't let go!" His desperate shouts and the howling of the wind were the only sounds Rose could hear as she held on for her life. Her fingers that were gripping the lever were aching. The thing that kept her holding on was the thought of the Doctor being alone, without her. She couldn't let that happen. The thought of him being alone brought out a new strength in her and kept her fighting.
Just as Rose was sure the lever was going to slip from her hands, the intense white light filtered out of the room, and the void sealed off forever.
"Systems closed," the computer said.
The Doctor leaped up with joy. "We've done it!"
"Yes!" Rose said, laughing in triumph. Her arms and fingers ached, but she didn't care. They had been faced with a nearly impossible task, and they had done it. The Cybermen and the Daleks were trapped in an eternity of hell, and they'd saved the universe, once again.
"Oh Rose, I thought I was gonna lose you," the Doctor said. He ran over to her and wrapped his arms around her.
"So did I," she said, relieved to be in his arms.
Then, she remembered.
Her face fell and she pulled out of their cuddle. Adjusting her jacket, she walked over to the vast white wall where the void had been sealed. She stared at it. Her mum was stuck in the parallel universe which had been shut off forever, along with the Void. She would never be able to see her again, as well as her dad and Mickey. She hadn't even said goodbye. In all the rush of world saving, she'd had to push it out of her mind. She let her fingertips brush the wall as she stood there silently, trapped in a state of shock.
Taking a deep breath, she turned around to face the Doctor.
"Mum, Dad, Mickey... Are they safe?" she said, her voice unsteady.
"Yes. They're safe," he said, swallowing.
She looked at the floor as a few moments of silence passed.
"They're gone," she whispered, her eyes glazed with tears. She closed her eyes and melted into the Doctor's arms as she wept uncontrollably.
"I know. I know." It barely came out as a whisper. He held her tightly and stroked her hair.
When she felt like she could move, the Doctor put his arm around her waist, and they trailed towards the TARDIS, leaving behind the mass devastation caused by the battle.
A few hours later, Rose heard a soft knock on her TARDIS bedroom door. She was curled up in a mess of duvet and bed sheets. Black make up stained her cheeks and her eyes were sore.
"Come in," she croaked.
The door slowly opened and the Doctor crept in.
"Rose," he said, softly, his voice full of pity. It killed him to see her in that state. He perched on her bed and smoothed her arm.
"We're at your flat," he said. "When you're ready, you can come 'n collect anything you want to keep."
She lifted her head and sniffed. "I'll come now," she said.
They stood up and he looked into her eyes. He pulled her in and cuddled her. "I'm so, so sorry, Rose."
Rose took a deep breath and stepped out of the TARDIS. She was instantly greeted by the familiar smell of the flat. It was left a little untidy, as it would have been on any regular day. This was where she'd grown up, yet she'd never felt as far from home as she did when she was stood there, alone in the silence. Trying not to reminisce too much, she entered her bedroom.
First, she pulled out a few large photo albums from underneath her bed. She couldn't bring herself to look inside. Then, she picked up a small box from a drawer, which she'd made as a child. It held a lot of her memories from when she was younger. Scanning the room, she picked up her last few favourite bits and pieces and left it.
Rose stood outside her mum's bedroom for a while, hesitating to open the door. Finally, she built up the courage, and pushed the door open gently. Her heart fluttered as she stepped inside. The pink walls gave the room a warm, inviting feeling. She walked around a number of times, before stopping at the dressing table. There was a small picture frame, containing a photo of Rose and her mother. She added it to her pile of belongings. Next, she opened her jewellery box and found her mum's favourite bracelet. I was given this by your dad. It means so much to me, Rose. One day, I'd like you to have it. Rose remembered her mother's voice so clearly that it brought tears to her eyes. She slipped it onto her wrist and fingered the dainty emerald beads.
Taking one last gaze around the flat, she sighed. Life would never be the same again. She turned away for the last time, and stepped into the TARDIS.
She sat down in the console room of the TARDIS with the Doctor. For a few minutes, they sat there, saying nothing.
"Are you sure there's no way back?" Rose said quietly, breaking the uncomfortable silence.
"Yes. I'm sure." He took a deep breath. "I'm sorry Rose, I really am."
"But you're the Doctor! You can do anything!" she said. But, from the sadness in the Doctor's eyes, she realised that she was fighting a lost cause.
He shook his head and smiled, but it was a doleful smile.
"I'm sorry Rose. Not always. Not this time." The Doctor glanced at the computer screen and then hopped over to it. "Buuuut," he started, tapping a few buttons. "I think there is one last gap in the universe. We can that can use to talk your mum for one last time."
A bubble of hope swelled up inside her. "Really? Can I really see her?!"
"Yes, if this works. It's going to take a lot of power." He danced around the console, pulling leavers and flicking switches, his eyes narrowing in concentration. All of a sudden, the TARDIS burst into action, and Rose held onto the seat as the spaceship shook. "Aha!" he said, as it steadied. "Now, stand over there Rose," he said, pointing to a space next to the console. "It's time to call your mother."
