His dreams were always the same – her chilling scream as fell towards the Void, his heart breaking as she vanished in the arms of her father (from an alternate world). They had shared one final, terrified, broken look before she left her world. Soon after, the Void collapsed in on its self, right before his eyes, as if it had never existed in the first place; as if Rose Tyler had never existed.

The Doctor had dreamt of nothing since, even with the return of the Rachnoss, and the Master, his mind always returned to that which he lost in the Battle of Canary Wharf. Her cheeky smile, her sense of humanity, how she had promised to be with him forever…. How she loved him without ever getting the chance to actually be with him.

He had met Astrid and Martha, Donna and the Captain once more and felt like he was moving on with his life, when in reality he knew Rose was always there, in the back of his mind, calling to him, whispering her love to him.

Their last conversation was one of the most heartbreaking conversations he had ever experienced. He never got to tell her he loved her, having miscalculated how long the supernova would last.

For him, it had only been a number of hours, whilst he guessed days for her – weeks even, as he called out through the smallest of gaps between the Howling, drawing her to Bad Wolf Bay. His actions burned up a distant sun, but it was worth it, he got to say goodbye to the Defender of the Earth… the love of his life.

And now, he'd found someone to travel with who wasn't looking for a relationship, someone who just wanted to travel to these fantastic, brilliant places and live her life to the fullest with just a mate. He'd worried she may grow attached, but Donna had already proved him wrong.

He'd given Donna the push she needed to 'walk in the dust' and gratefully accepted her into his home. But it would never be the same…. Not like his Rose. She was one in 4 billion that was so human she out shone the sun.

But she could never return, she would always be lost in Hell. And there was not a damned thing he could do about it.
