Those precious three days that the Doctor and Rose knew were their last together, had gone by so very quickly. They both so desperately wanted more time together, but they both knew that that was never going to happen. This was it; the end; their final adventure.

The Doctor especially was finding it hard. The last three days would always be in his hearts, maybe more so than the rest of the days he had spent with Rose over the last few years. He knew that he would lose her one day, he had always known that. But he didn't expect to have to lose her so soon or in the way that he had lost her. Even though she was here with him at the moment, by the end of the day he knew she wouldn't. It was hard for him to comprehend. He didn't want this to happen, but he had to stay strong and he had to just accept this. No matter how hard it would be.

Rose didn't want to go, she wanted more than anything to be able to stay with the Doctor forever, but she knew she couldn't. This was really it. She would never be by his side again. Not until he dies, but she hoped that that wouldn't happen for a while. She would want him to have a long life and move on.

Donna, Martha and Jack, didn't know what to do. They had seen how the Doctor and Rose had been over the last three days. They knew that the end for just around the bend. It wouldn't be long until Rose was really gone forever. They knew that by the end of the day Rose would be truly gone forever. It was hard to imagine life without her. Even though they thought that when she first died she was gone forever, when she came back it was like it had never happened and that it was back to old times. Even though she was a butterfly, it made no difference as far as they were concerned. It was just hard.

The Doctor and Rose sat in the TARDIS garden together and alone. They sat there in silence, not knowing what to say to each other. They were both thinking of the adventures they had been on together. How some of them had made them laugh; how some of them had made them scared and how some of them had even made them cry.

As they sat together, Rose would occasionally look over at the Doctor sat on the grass and he would look at her for a second, but they never caught each other's eyes. They didn't even realise that the other was looking.

The garden was bright and colourful, but their moods weren't. If it had been raining and had a greyer feel to it, then it would probably match their moods. They were both sad, and they just didn't know what to say to each other in attempt to cheer each other up. It was like they had already said it all. The line of a song popped up in their heads: Said it all, nothing to say at all.

"I don't know what I am going to do without you, Rose." The Doctor's voice was low and full of emotion and it startled Rose when he spoke.

"I don't know what I'm going to do without you either." Rose said back, her voice, too, full of emotion.

"This is so hard. In a few hours I'm never going to see you again and I just don't know what to do."

"You'll be fine."

"Really?"

"Yes," Rose said it in a way that sounded like she was certain. The Doctor did everything he could to believe her.

The two of them were back in silence again soon after. They continued to stare at the view of the garden. It was beautiful and they realised that this was the only happy thing that was in here.

"I don't want to go." Rose admitted breaking the now defining silence. The Doctor looked at her.

"I don't want you to go either." The Doctor's voice hadn't lost any of the emotion, if anything it had gained more. He didn't want to break down. That wasn't how he wanted Rose to remember him. He wanted to be the bubbly, smiley Doctor that found adventure in anything, but there was no way he could be that Doctor now. He just couldn't be him.

"I need you to promise me something, Doctor." Rose told him finally turning around to face him fully. Her small butterfly form moving closer to him.

"Anything,"

"I need you to promise that will move on, that you will be happy. That's why I was sent back, remember? To help you move on, to tell you to move on."

"All I can do is try, but I can't promise anything. This is hard, Rose. This is one of the hardest things I have ever been through." The Doctor didn't know if he could, but he would try for Rose's sake. She had come back in order to help him to move on, all he could do now was repay her for her actions by doing what she set out to do. It would be hard, there was no doubting that, but deep down, maybe there was a chance that he could move on and be happy again.

"Thank you."

Suddenly a light shone in the corner of the Doctor's eye and he looked down to see Rose bathed in a bright gold light. He looked down in surprise and knew that this was it. It was finally happening.

"Rose," he breathed.

Rose looked at herself before looking the Doctor in the eye. "It's time." She whispered.

"No, no I'm not ready." The Doctor's voice was slightly panicky now.

"I'm sorry, I really am. Doctor, there's nothing I can do."

"Please don't go. You can't go."

"I'm sorry." The light shone brighter and the Doctor moved back away from the light. The light seemed to get further away, but as it did a figure became visible. Even though the Doctor couldn't see the figure's face, but he knew that it was Rose. He could instantly tell. He would know her anywhere.

"Rose,"

Rose stepped out of the light. Her appearance not quite full, she was like a ghost. She was a ghost. It had been a long time since the Doctor had seen Rose like she used to be in her human form. For a second or two it felt like she was back with him and that she wasn't going away. But then the reality of what was happening hit him again and he looked at her with sadness visible in his eyes.

"I can't believe this is really it." He said trying not to break down.

"I know," Rose looked down sadly.

"I'm going to miss you."

"I'm going to miss you too." Rose had tears running down her ghostly cheeks now and the Doctor was nearly there.

"God, this is so hard. I really don't want you to go."

"I have to."

"I know,"

The Doctor could see that she was fading now and he knew that he had to say what he had needed to say for ages now. He moved closer to her and pressed his lips to hers. Rose responded and it was only a few seconds before the kiss ended. They couldn't waste time, not again. Rose looked at the Doctor and he looked at her.

"I love you Doctor. Remember that. If nothing else, then just please remember that I love you." Rose was really beginning to fade now and the Doctor had to say it before she disappeared again forever.

"Rose..." he choked on his tears when saying her name and tried to recompose himself before saying what he was so desperately trying to say. "I...I...I lo..." but she was gone.

The Doctor collapsed to the ground, weeping. He put his head in his hands and screamed in anguish. She was gone, she was really gone. And once again he had run out of time. He hadn't told her what he wanted to tell her. Once again, the Time Lord had run out of time.

~...~

He felt numb, really numb. He didn't even feel anything when Jack had come in and held him as he cried. Jack couldn't help but cry with the Time Lord and when Martha and Donna had come in, they too, had cried with them.

"I run out of time. I never told her. My last chance and I never told her." The Doctor sobbed. Jack didn't say anything, but knew exactly what the Doctor meant. He knew what Rose had meant to the Doctor and he knew what the Doctor had wanted to tell her for so long now. Jack knew that the Doctor loved her and now she was gone and he couldn't tell her. Sometimes life just wasn't fair.

However, the Doctor kept with him Rose's words. He would move on he knew he would. He had to. Even if it was the last thing he did, he would make sure that he kept his promise to Rose. He wouldn't let her down.

Butterfly fly, fly away from her
I know we'll try
Through the laughter and the tears
You'll always be a part of me
And in my heart you'll always be
Butterfly, fly, fly away
fly away
