Legalities first: I don't own anything you'll recognise.
This is set after a reunion with Rose. And there is only one thing I have to say. I'm sorry. I cried all the way through writing this, even more than I did when I wrote the beach scene for my reunion. So sorry if I make you cry too.
It had been 60 years since the Doctor had managed to get Rose back, but now he was losing her again. When he realised that within a few months he'd be able to see Rose again once the hole in the void had began to grow, he'd taken extra care to make sure he kept his same body. To start with, in his state of extreme depression and grief he didn't care. He let the Plasmavore drink his blood, got himself electrocuted to stop the Daleks, even had a sun living in him to save Martha. But when he realised he could get Rose back he was overly cautious, not wanting to regenerate, wanting to be the same Doctor for when she came back. He didn't want to lose her love and trust even slightly like what happened after his previous regeneration.
But here they were, 60 years on, Rose was old now, dieing. She was lying in their bed, old and frail, but still as beautiful as ever in the Doctor's eyes. Her tired eyes flickered open looking down towards the Doctor sitting by her bed, leaning over and holding her hand in his to his cheek, floods of tears streaming down them. She smiled up at him, and he smiled back in spite of the pain ripping his hearts apart.
"Hey," he voice was soft and wavering, and the Doctor noticed her eyes were glistening with tears
"Hey," and he leaned up and lightly kissed her cheek.
"I.." she started coughing.
"Shh, shh, don't talk"
"I love you"
The Doctor smiled, a fresh wave of tears cascading down his cheeks. "I love you too, forever"
Rose smiled, and stifled another cough. She knew it was the end, she could feel it. But there was one last thing she had to say. One more thing for him to remember her by.
"Before I go Doctor"
"No, it's not time yet,"
"No Doctor, please. Before I go, I just want to tell you: you were fantastic. Absolutely fantastic! And d'you know what? So was I."
The Doctor let out a small chuckle that quickly turned into a sob he attempted, and failed to stop.
Rose smiled, and closed her eyes. Forever. The last image the Doctor would have of her was of her smiling. Just the way he liked it.
The Doctor's breath caught in his throat. She was gone. He collapsed into violent, shuddering sobs and lay his head into Rose's stomach. His hearts were shattered, broken into hundreds of little pieces as Rose let out her final breath. She was gone, but she would always have his hearts. Forever.
