"Rose, do you mind?" The Doctor said as Rose kicked the console. "That's my time machine you're hurting!"

"No I don't mind," Rose shot back, her foul mood ever present.

"What is wrong with you?" The Doctor frowned at her, pulling a lever before stuffing his hands into the pockets of his long brown trench coat.

"There's nothing wrong with me!" Rose said stomping about and throwing herself down on the chair, putting her feet up on the console.

"Well will you stop doing this!" The Doctor said, moving her feet.

"Doing what?" Rose thundered folding her arms.

"Being so…moody," the Doctor replied leaning against the console. "You're starting to turn into your mother!"

He hadn't meant that. He really hadn't meant that and he had no idea what had made him say it. The Doctor could see the damage that comment had done. The pain behind her eyes was evident.

"Well maybe I should just go home then!" Rose shouted, standing up and running to the TARDIS doors as it landed.

"No, Rose, wait!" The Doctor said calmly, trying to ignore the instincts telling him to follow her and wrap his arms round her. He'd never understood how these human emotions would work.

Rose flung the doors open and slammed them behind her as she ran towards her mums flat.

"Why does she always slam the doors?" The Doctor asked no one in particular, looking up at the Time Ship. Glancing at the screen on the console and seeing that Rose was crying he decided he'd have to go after her.

Careful to shut the doors rather than slam them and lock the TARDIS before he set off, he caught a glimpse of Rose turning as she got to the stairs instead of going up them to her mums flat as usual. Where was she heading? Running to catch up with her he saw her heading towards the park just off the estate, near where he'd parked the TARDIS the first time he'd met her.

She paused when she reached the park, leaning on the railings and watching the kids playing. The Doctor slowed to a walk and stood next to her, glancing momentarily at the children on the swings.

Rose sensed him next to her and wiped her tears away, not looking at him. He leant with his back against the railings and looked at her long and hard before speaking.

"I'm sorry," he said quietly. "I didn't mean what I said. I just have a hard time understanding human emotions sometimes. You'd think I'd have the best of both world being half human, half time lord."

"Yeah, well…" Rose said still not looking at him and sounding like she hadn't quite forgiven him for the comment.

"Oh, Rose, c'mon, cut me some slack!" The Doctor said pleadingly. Rose took her arms of the railings and started walking away, ignoring the Doctor.

He walked beside her trying to take her hand but she kept pulling it away.

"Rose, I said sorry," the Doctor said quietly. "You can't hate me so much that you won't forgive me."

In truth Rose didn't hate the Doctor. She hated the way he made her feel. One minute he would make her feel like she was the best person in the universe, who could do anything and the next, he would put her down and make out she was stupid. That was why she loved him and yet hated him. Just recently it had come to a peak and she hadn't been able to take anymore of it. Especially since his regeneration.

"I can't do this Doctor!" She said turning to him suddenly. The Doctor was taken aback by her response.

"Can't do what?" He asked confused.

"You drive me mad!" Rose said waving her arms about. "One minute you're the greatest person I've ever met, my best friend, my soul mate, the next your like this horrible idiot who has no idea how nasty their comments are!"

The Doctor paused looking her straight in the eye to make sure she wasn't just having him on.

"Sorry," he said after a moment still frowning.

"Sorry isn't good enough, Doctor," Rose said continuing to walk along, the Doctor following. "It's just a word, like the ones you used to convince me to come with you. I need to know that you'll do something about it because I can't go on living like this."

Rose could hear herself saying all these things she knew that the Doctor had no control over. In reality she knew it was her fault she felt like this. If she weren't so madly in love it wouldn't hurt like this.

"Rose, I need to know what you want me to do," the Doctor said watching as she hugged her arms about her.

"I don't know!" She said desperately. "I just need to stop feeling like this!"

"Like what?" Asked the Doctor. Rose looked about shrugging and opening and closing her mouth as she tried to explain what she meant. She could hear the haunting strains of 'Twinkle Twinkle Little Star' coming from and ice cream van just up the road.

"I don't know…" she said again the tears starting afresh. The Doctor opened his arms to her and she gratefully accepted the hug. She began whispering in his ear. "I'm sorry… I didn't… I just… I'm so sorry…"

"Hey, it's alright," the Doctor said hugging her tightly. He heard her gasp and pulled back a little. "What?"

Rose stared at the little girl on the corner. She was ghostly pale and was looking straight at her. She seemed familiar but Rose couldn't quite put her finger on where she'd seen the girl before.

"Rose, what are you looking at?" The Doctor as following her gaze and seeing nothing.

"The girl on the corner," Rose said pointing. The Doctor froze, staring at her worriedly.

"Rose," he said quietly. "There isn't a girl on the corner."

Rose looked at him frowning. What was he playing at? Then she looked back and the girl was nowhere to be seen…
