The Doctor leant against the railing, staring in to space and as he thought to himself, thinking about the woman he had loved, he still did love her. But now she could never love him back, she was gone. He didn't want to hurt anyone else, everyone he got close to up ended up dying, or hurt because of him, because of his lifestyle. He didn't think it was best for Donna to stay with him, he cared for her, and the last thing he wanted now was for someone else to get hurt. But she insisted on staying, in a month or so she was going to join him again. She needed to be with her family at the minute, make sure they were okay.

His mind wouldn't stop thinking about Rose, she wasn't just his 'companion', she was everything. She had saved him so many times, she had changed him for the better. After the Time War he was lost and broken, and angry at everything around, and she saved him, made him see the brighter and happier side. Everything seemed so perfect when she was around, always seeing the positive in everything and everyone. He missed her.

"Doctor?" A voice whispered from behind him, jolting him out of his dream, and there was Jack standing by the doorway. Jack had stayed with The Doctor for a few weeks now, just to keep an eye on him for a while, making sure he was okay. The two of them for their chance to say their goodbyes to Rose, but now he knew it was his time to go. He had to get back to him, and leave the Doctor to his grieving.

"Ready to go?" The Doctor whispered, his voice hoarse and croaky from not speaking for hours, or days on end, he didn't really know how long it had been.

"Yeah." Jack whispered.

The Doctor parked the TARDIS in the middle of Cardiff, ready to drop Jack off where he belonged, defending the Earth with the rest of the Torchwood team. As the TARDIS came to a halt, Jack began to walk towards the door, stopping at the railings for a moment, turning back to face The Doctor once more.

"Doctor," he began, "I know you don't like talking about her, I know you don't, but just don't forget her." He whispered and The Doctor swallowed, "Promise me? Because I'm not forgetting her anytime soon.2

"Jack," the Doctor sighed and ran his hand down his face, sighing, "Do you really think I could do that? Just stop and forget her like that?"

"No, I guess not," Jack shook his head, "don't forget me either, I want a visit now and then, at least once a year. If you need to re-fuel, come and see me."

"Jack..."

"I loved her too Doctor, not as much as you, or in the same way, but I loved her. She was like my sister; we have to remember her, together."

"I know Jack," the Doctor nodded.

"If you want to talk-"

"Jack, just go," He whispered, hoping it sounded polite and not too harsh, "Your team needs you."

"Will you be-"

"I'll be fine Jack," The Doctor nodded towards the door and watched as once again, another companion was leaving him, moving on with their lives. "I'll be fine." He whispered to himself, hoping it was going to reassure himself, because to be honest, he didn't quite believe he would be alright, at least not for a while.

The Doctor walked around the TARDIS, not knowing what to do with himself, he didn't feel like travelling, like going anywhere, Donna was at home in London, she gave him gave him strict instructions not to venture far away. But he didn't want to go anywhere. He didn't see the point.

Everyone was gone. He was alone. Martha was gone, Jack was gone, Donna said she was going to be coming back, but it was only a matter of time before she left too. Everyone said they would stay forever, but he knew that wasn't possible. Rose had proven that, they'd promised one another forever, and look at what happened. She was never coming back, never venturing to another star or a planet.

The Doctor smiled for a moment as he thought about the fun two of them had together, and the adventures they could have had. Then he remembered what Jack had said about not forgetting her, he wouldn't, of course he wouldn't, but he couldn't just sit here alone, not doing anything, just wallowing in his ship. He was going to travel, travel right across the Universe, not for himself, not for his enjoyment, but for the one woman he loved, the only woman he had ever truly loved.

Rose Marion Tyler.

He would travel for her, and travel in her memory.

Forever.

THE END.
