This chapter's BIG COOKIE goes to evil is good because her reviewmade my day. (lmao that sounds amazingly corny, but it sounded good in my head! Honest!) Anyway, heres chapter three :

Chapter three: realisation

She didn't do much these days. They still went on the same exciting adventures as before, the same life threatening adventures. They would still run for their lives to reach the TARDIS, but there wasn't as much passion in her run as she ran to the doors. When they saw new things, which even The Doctor hadn't seen before, there wasn't the same fire in her eyes as he told her where they were or what something was. He knew this was because they would have to come back and run more tests and try and figure out what was wrong with Rose. He just wanted a clue; any clue to what it was that was wrong with her.

He could tell that it was getting to her too. She would hardly talk. She would just sit there staring into space (literally). She wouldn't tell I'm how she felt about anything and it was ruining their relationship to the point where he felt like he was just the guy who showed her things, not The Doctor, the man she loved who showed her the universe and would risk his life to save hers. When they got back to the TARDIS she would either go straight to her room or to the med bay, knowing more tests were to be taken whether she liked it or not.

It was after they had gone back to raxicorricofallapatorius to visit the slitheen family before they had turned crazy that they found out what was wrong with Rose. She had been getting more and more exhausted after the journeys and so they knew it was getting worse. She went to the Med bay and sat on the table as if it was all part of what she did now.

The Doctor placed the scanner over her body and selected what it should test for.

"Doctor?" She said suddenly

The Doctor was taken aback when she talked because she didn't normally speak to him apart from in the mornings when she would ask where they were going that day.

"Yes Rose? What's wrong? Are you ok?" He said worried.

"No, nothing, its just how many or these tests have we done on me?"

"Ermm…. 17. Why?"

"And how many are there?"

"About 3000" He said sitting down on the edge of her bed lightly. "Is something wrong?"

"What's the chance that we are going to find what I have before I…"

"Don't you dare. DON'T YOU DARE SAY WHAT I THINK YOU ARE ABOUT TO SAY ROSE BECAUSE IF YOU SAY THAT THEN ALL HOPE IS LOST. YOU HEAR ME? ALL HOPE." He shouted angrily. He wouldn't let her say it, he wouldn't let her say that she had given in to what ever this thing was. He dropped his eyes ashamed he had just shouted at her.

"I'm sorry."

"No I'm sorry doctor. I shouldn't have said anything."

"Rose, we are going to find this thing, what ever it is, before anything happens to you ok?"

"Ok." She said not quite believing it.

He turned the scanner on and light flashed over Rose's body. It flickered and turned off. Rose was used to this routine by now and didn't sit up straight away, knowing that if she did she would feel very light headed.

Something beeped on the screen and he said something in gallifreyan before turning to Rose. She knew it wasn't his normal saying because it sounded different. This one was less violent and for a split second he looked like he was going to cry. The moment was over and he regained his composure before turning to Rose with a sigh.

"You know what I have don't you."

"Yes I do. I told you I would find it!" he said sitting down and prodding her in the nose. She smiled a smile he hadn't seen for a long time.

It felt as though the gap between them that had been growing since the "accident" had just disappeared and they were back to how it used to be.

She hugged him close, sorry for what she had put him through. "I'm sorry I've been so… distant. But now its all going to be alright isn't it? You know what I have. You can fix it?" she said looking up at him hopefully.

"If only I could…" he thought looking away. He didn't want to tell her the news which would change her life forever.
