Author's Note: Thank you so much to reviewers, especially Evan and Gallifrey's Rose. You guys are why I keep writing. I really really really hope you enjoy this chapter. It gets quite soft IMO but it was necessary. There will be plenty of fun in the next few chapters, promise!

I don't own Doctor Who, blah blah blah...

Rose was watching The Doctor and Martha outside the TARDIS in Martha's living room. She was happy that he would have someone solid and human with him, he needed that, but she also felt a little pain inside her chest. The TARDIS hummed in concern at her.

"It's nothing, just jealousy. I had expected to have overcome most of these emotional connections by now. I certainly won't let it interfere with my task." She replied to the living machine. The TARDIS doors opened and in ran Martha and The Doctor. He saw Rose straight away.

"Martha, I don't know about you, but I think I could do with some rest before our next big adventure." He said, not acknowledging the woman in the red dress.

"Yeah, come to think about it I could do with a good night's sleep. Who knows where we'll end up next." Martha replied.

"The TARDIS will help you select a room. Make yourself at home." The Doctor smiled at her. She went down the corridor.

"I see you asked Miss Martha Jones to become a full time member of Team TARDIS. She's brilliant." Said Rose.

"Sure you're not a little bit jealous?" He asked her, coyly.

"Jealousy is such a human emotion, and as you know I'm not human." She retorted.

"Let's go somewhere a little more comfortable, shall we?" The Doctor suggested and in the blink of an eye they were both standing in the TARDIS library. It was a huge, dark room with all the walls lined with books and a couple of leather lounges, both with books stacked beside and in front of them. The Doctor took Rose's hand and led her to the lounge in front of a warm, roaring fire.

"What a strange sensation, going from one place to another in the blink of an eye." Rose mused.

"I would have thought that you were used to it." The Doctor responded, gesturing for her to sit down next to him. She obliged.

"What do you mean?" Rose asked. As she sat she put distance between The Doctor and herself. He was not the same man as when he left the TARDIS this morning.

"Well, that's how creatures of the abstract travel, isn't it?" He asked her. His face had business written all over it, there was no emotion. This hurt her. The last time that he looked at her like this was on New Earth when her body was taken over by Cassandra. But that didn't feel as bad as the sinking feeling, the realisation that he knew what she was.

"It is, but when a creature of the abstract does it we are not caught off guard." She replied, acknowledging her defeat. "How did you find out?" She asked him.

"When I was putting on my tux. I had a little bit of time to think. You said that you were in my mind, and the only other being that can do that without my consent is the TARDIS. And you communicate with the TARDIS constantly, I can feel it. I don't know what you are saying, but I can feel it. And the TARDIS recognises you as a life form. Clearly you aren't just in my mind." He started.

"As for your shape, only someone who has met me would have knowledge of my affection for Rose. Therefore you are someone that I have encountered before. Now the tux got me thinking about the Cybermen on Pete's World and how they imprinted themselves on this universe to get through. You seem so much like Rose in her mannerisms and you have her memories, therefore you are deeply connected to her, entwined even. There was only one creature I could think of that could imprint themselves on the TARDIS and come through, alone." He stopped. The room was completely still. Rose was holding her breath.

"You are the Bad Wolf." He finally declared. She exhaled.

"I am, well done."

"I thought I got rid of you back at the Gamestation, before I regenerated." The Doctor said.

"Not completely. The time vortex had completely bound with Rose. Residual amounts of the vortex remained attached to her DNA. I lay within her, dormant." She informed him.

"What woke you up?" He asked.

"It takes a great shock to the system to reignite the time vortex particles. It was a combination of the distress of adjusting to a whole new universe combined with the terrible pain from heatbreak that brought me back."She told him. Her voice was trembling and the pain that she spoke of was visible in her eyes.

"I was suffocating in that universe, it was the wrong type of time energy, and I could not co-exist with Rose. I decided that I had to bring myself back, and your beautiful TARDIS helped. I am eternally grateful to her. She is my kin, you know." She finished. He was looking at her with great confusion. He didn't know what to make of this creature, this woman in front of him that was created to save him and had overcome great struggles to survive.

"But imprinting yourself on this universe and coming through would have used up so much of your energy. Why didn't you just return to the time vortex?" He asked.

"I did, for a while, but then I saw how much pain you were in. Remember I was created to save you, I was born with pure and selfless love in my soul and it was all for you. I couldn't stand to watch you like this." She stroked his face and took his hand into hers. Tears started to drop from her eyelashes.

"But you could have destroyed the universes by coming through, why would you risk that?" Asked The Doctor.

"Because you need protecting." She told him, wiping the tears from her face. "There are important times ahead. I cannot see them clearly, but I know they are ahead. And you need someone to help you."

"Oh, Rose." He wrapped his arms tight around her as she sobbed into his shoulder. Abstract being or human being, the woman beside him was his Rose. She had the same mind and the same caring eyes. She may not be the human he saw crying on the beach in Norway, but she was the soul and essence that captured his heart a lifetime ago.

She pulled back and he wiped her eyes. "I didn't know what you would say about me coming through from the other universe. I was so scared to tell you." She sobbed.

"The instinct to survive, that is so very human, and you are all but one." The Doctor reassured her, "Its ok, we'll do a scan of space and make sure that there aren't any cracks or links to the universe after we all get some rest."

"Thank you, Doctor, for understanding." She smiled at him.

"There is one thing though, that I want you to do." Said the Doctor to Rose.

"Anything, anything for you." She replied.

"I want you to reveal yourself to Martha."

Ooh, what do you think will happen next? Did you see it coming? What do you think Martha will say/do? Remember this is fan fiction and doesn't have to stay the course of the series... Next up, Martha meets Abstract Rose.
