The Doctor watched Rose and her Doctor, as they chattered happily, as he asked her about her small trip away. He had the tiniest flicker of worry on his expression every time that Rose turned away to talk to the Doctor, as if he was worried that Rose would leave him, that Rose would chose the Doctor with the Tardis, the Doctor that could take her to the stars, through time and space, instead of stuck here with him.

To be honest, the Doctor wasn't sure which he would rather. He wanted to travel with Rose again, the thought made him ache with happiness but she was happy here, and she had her Doctor, they could grow old together. Together, where he could not. The curse of the timelords, he would always be left alone again, left to wander the universe. Just a mad man with a box. Was he selfish enough to do that? If Rose asked, would he say yes?

He watched her eyes light up at her Doctor, with their hands linked under the table, and thousands of unsaid things passing between them. The way he seemed to smile every time that he glanced at her, the way that she had smiled on the beach when thinking about him.

Stuck with you, it's not so bad.

Yeah?

Yes.

He smiled sadly at his yellow and pink Rose Tyler, and she turned and beamed at him. It made his hearts ache. He could see the difference in the smile she gave him to the smile she gave her Doctor, for him it was purely affection with a hint of the love she had for him. She would always love the Doctor, but now she had her Doctor, and he loved her, more than the Doctor could because the Doctor could never admit it, and he could and did, and they had each other.

"Excuse me," Rose said, disappearing out of the room and into the hall to the bathroom.

The two Doctors stared at each other for a few long moments. Strange that at one time they had been the same person, with the same memories and now they differed. The Doctor had memories of Amy and Rory and River, of new adventures and aliens. The other Doctor had new memories of Rose, of domestics, and owning their own house with a Tardis blue front door. Of the adventure that he could never have.

He stood abruptly and headed to the door. "Doctor?" Her Doctor said, before he left the room, he turned to face him. "Say goodbye to Rose, she was distraught she didn't get to last time." Pain jabbed at him again, at that thought, when he left Rose and her Doctor at Bad Wolf Bay… he nodded sharply. "Oh, and Doctor?" the Doctor waited.

"Allonsy."

The Doctor couldn't help but grin, at the connection the two of them held. "Geronimo," he replied with a smile. "Goodbye Doctor."

"Goodbye."

The Doctor left the room, and the house with a half smile at the door. He was halfway back to the Tardis when the door flung open. "Doctor!" Rose yelled, running to him, he stopped and turned and she flung herself into his arms. "You have to say goodbye," she muttered into his neck.

"Goodbye Rose Tyler," he said voice quiet as she withdrew from the hug.

She leant forward and kissed him on the cheek. "Goodbye Doctor," behind the both of them her Doctor was standing by the front door watching them, a faint look of longing at the sight of the Tardis in the background.

He turned to leave, and had only managed two steps before Rose called his name once more. He turned. "Doctor, you were fantastic, absolutely fantastic."

He beamed at her. "You keep running Rose."

"Till the end of my days."

They stared at each-other for a few moments with a smile before he turned back to his Tardis, the only constant in his life. He reached the door and turned to see Rose embracing her Doctor.

"I thought for a moment you were going to leave."

"Never."

Her Doctor smiled as he twirled her around, turning to look as the sound of the Tardis brought to their attention the leaving Doctor. They held hands and watched, a reminder of their days as travellers.

Review please. Or I'll send a Dalek after you.
