A/N: Enjoy this chapter. Unfortunately it is now too late to concentrate and I might collapse if I stay here any longer but I said I'd update today so here you go. Enjoy! By the way, I'm getting worried tht I won't be able to slot in Rose's new back story after Journey's End but I will try. Enjoy. Please excuse the mistakes.

Disclaimer: I don't own Doctor Who or Harry Potter. Strangely enough though I have now coined, Harriet Porter. Don't ask. That was a tangent and a half.

Chapter Eleven – Lost

Rose sat at the Noble's kitchen table with her head in her hand. Out of the corner of her eye, she could see Wilf and Sylvia huddled on the sofa in fear and she could hear the Daleks still giving orders. Then she heard another noise. A rhythmic four beat signal. Had she not been in the parallel universe when the master had come, she would have recognised it as his drum beat.

As it was, it still made her sit up to attention. She was looking around for it when Wilf pointed at the laptop and Rose heard a voice coming through the speaker.

"Can anyone hear me?" It asked and Rose recognised the voice but couldn't place it. "The sub wave network is open; you should be able to hear my voice." She got up and walked towards the screen and slowly she began to realise who it was.

"I recognise that voice." She said to no one in particular and knelt down by the screen. She'd last heard that voice at Christmas one year, so long ago now. "Harriet! It's me! It's me!" Rose yelled at the screen, and then felt silly. There was no way Harriet would be able to hear. "Oh she can't hear me." She turned to Sylvia and Wilf. "Have you got a web cam?" She asked. 'Please, please say yes.'

"No. She wouldn't let me. She said they're naughty." Wilf blamed it on Sylvia and Rose felt her heart drop. But she soldiered on.

"Well, I can't speak to her then, can I." She told the screen mentally kicking herself for not learning enough about computers off Mickey. She watched as the screen split into four and three of the spaces were filled. Jack in the top right, Sarah Jane: bottom left and Harriet Jones: top left. The last space remained empty.

"The fourth contact seems to be having some trouble getting through."

"That's me! Harriet! That's me!" Rose yelled at the screen again, forgetting her embarrassment.

"I'll just boost the signal." Harriet told them and the fourth screen was filled. But it wasn't Rose. 'Hey!' Rose thought. "Who's she? I wanna get through." She felt a bit childish for saying it but they were her friends and then that dark-haired, dark-skinned, soldier-type just swans in and takes them? Not on her watch. The fourth person might be pretty but Jack's greeting automatically made Rose jealous. She had to quickly remind herself that Jack always did that. And besides: She loved the Doctor. That's why she was here. She was just wondering who the mystery woman was and what her connection was when she tuned back into the conversation just in time to hear Harriet speak.

"…Martha Jones, former companion to the Doctor."

'WHAT?' Rose thought loudly. "Oi! So was I!" she said aloud. 'He's replace me.' She thought jealously. She knew about Donna obviously but she also knew that Donna didn't care for the Doctor in that way. She had no idea about this 'Martha Jones'. She watched them banter on for a bit but didn't take any of it in. Not until Martha began to speak again. Rose chastised herself. Why was she getting jealous of someone she didn't know. Besides, the Doctor loved her. That's what he was going to say. Wasn't it?

"The Doctor's got my phone on the TARDIS and I can't get through." Well that was something at least.

"Nor me and I was here first." If Rose couldn't reach him, she was glad nobody else could either. She felt selfish but she also felt that the Doctor was hers.

"Well, that's why we need the sub wave." Harriet continued, thankfully unaware of Rose's argument with herself. "The Doctor's secret army." Harriet called them and Rose raised an eyebrow briefly. She hadn't been one for reading before she met the Doctor but she had read the Harry Potter books, if only to find out what everyone was on about, and it reminded her of 'Dumbledore's Army'.

She hadn't read the last one yet though. She had tried to find it in the parallel world but it was a completely different story. The closest she could get to the book was 'Harriet Porter and the Deadly Hallways'. As it turns out, the book was about a female werewolf cum witch who solved mysteries in the dead of night with only a hairpin, a wand and a small slab of chocolate. Apart from the female werewolf/witch part, Harriet had reminded her of someone else she knew so she had read it anyway.

Rose was only mildly surprised to find that her mind was wandering again and turned back to the conversation.

"Calling the Doctor." A computer voice said from somewhere on the end of one of the lines.

"So am I." Rose fished out her phone. If anyone was going to reach the Doctor, she wanted it to be her. Rose got Wilf and Sylvia to ring the number as well. She held her phone up to the sky, reaching up to him, closed her eyes and wished.

"Find me Doctor. Find me."

Rose sat at the laptop and looked sadly at Harriet Jones' empty space. That's when it flickered and she saw the Doctor and Donna appear in its place. She watched as they all started jabbering at once, automatically feeling left out. She wanted to talk to him.

"Doctor. It's me." Rose said quietly knowing he couldn't hear. "I came back."

"It's like an outer space Facebook." Donna grinned merrily.

"Everyone except Rose." The Doctor agreed and his face fell slightly. Rose's, on the other end remained blank. 'At least he's remembered me.'

"Control? I need a number shift. Lock me onto the TARDIS. Now." Rose closed the call on her phone and stood in the middle of Donna's front room with the oversized gun back in her hands. "Right." She turned to Donna's family. "I'm gonna find him." She beamed. "Wish me luck."

"Good luck." Sylvia smiled supportively.

"Yeah. Good luck sweetheart!" Wilf called out to her and with a flash of electricity, Rose felt herself disappear.

Rose landed in the middle of a desolate road covered I abandoned cars and wreckage. She wondered if she had the right place but then she saw the TARDIS at the other end of the road. Two people stood in front of it and she felt a smile break out onto her face when the taller figure turned and she recognised the tall, thin outline of the Doctor.

She stopped walking and her smile broadened. The Doctor just looked at her in wonder and disbelief before he broke out into a run towards her and she mirrored his reaction. The Doctor's pace becomes faster and faster and soon he is sprinting full pelt towards her. Rose didn't think she had ever seen him run so fast. Not even when they were running for their lives.

But suddenly, her dream became painful reality as she saw a familiar shape turn the corner so that it sat off to the side between her and the Doctor. She slowed to a halt as it raised its weapon and pointed at the Doctor who had also noticed it and stopped.

"EXTERMINATE!" the Dalek screeched and Rose watched in horror as the Doctor was hit and his body fell to the ground, limp.

Jack materialised in the distance and blew the Dalek to smithereens but Rose was only half aware. She dashed to the Doctor's side and, throwing the gun to the side, held his head in her hands and spoke to him hopefully, pleading he was still alive enough to hear her.

"I've got you. I've missed you. Look, it's me."

"Rose." He replied breathlessly. "Long time no see." He smiled up at her, his emotions bared for all to see. Rose could see the love that he normally held closed in his heart but she could also see his pain.

"Yes. Been busy, you know." She answered back, copying his habit of giving strange answers in times of trouble. 'After all,' she remembered that day on the beach, 'who replies to, 'I love you' with, 'quite right too'? It's only a technique of avoiding the real problem.'

The Doctor cried out and Rose forgot her strong outer appearance. "Don't die." She pleaded. "Oh, don't die. My God, don't die!" She begged, holding his head as it lolled backwards. 'Please Doctor. Live. For me.' She prayed in her thoughts.

"Get him into the TARDIS quick. Move." Jack cried, grabbing his arm. Rose grabbed his other arm, desperate not to let go of him. Jack let go of him as Donna took over and while the girls half dragged him to the TARDIS, Jack grabbed Rose's gun, marvelling at its build before using it to watch the small group's back as they went to safety.

Rose held him as he thrashed about on the TARDIS deck but Jack told her to get back.

"Rose, do as I say and get back." She ignored him.

"He can't." She tried to say but no sound came out. "Not now I came all this way." She found her voice again and it quivered as she watched the Doctor's face screw up in pain. 'Please. This can't happen again.'

"It's starting." The Doctor held up his hand and it glowed ominously.

"Here we go. Good luck." Jack called to the Doctor, taking a firm hold of Rose and leading her away.

Donna demanded an explanation and Rose gave her a very brief, shaky one before turning to the Doctor. "But you can't."

"I'm sorry. It's too late. I'm regenerating." And with those words, Rose's heart broke once more.
