A/N: I do not own Doctor Who, Sherlock, or any of their characters.

The Doctor let the TARDIS drift through empty space so that he could read the letter from the Time Lady he had assumed he didn't know. He dug the paper out of his impossibly deep jacket pocket and held it in front of him.

It was written in Circular Gallifreyan. The complex circles and lines that formed words. He read the letter.

My Dear Doctor,
I am so sorry that I didn't get the chance to speak to you again, and I'm afraid you will also never get that chance. I've used up my lives and will not be able to regenerate again. Do not weep for me, I lived a full 2000 years. Funny, you never really realize how short life is until you reach the end of it. Thank you, Doctor, for giving me one last, if small, adventure. Never forget me and continue the legend of our world.
Avashta

The Doctor's mouth fell slightly open and eyebrows disappeared into his untidy hair upon reading her full name at the bottom of the letter. A name he hadn't heard or seen since he left Gallifrey, never to look back. His surprise slowly melted into sadness, knowing that he would never see her again. If he was meant to, she would have remembered it. Some things, he thought, must happen.

The Doctor slowly wandered around the console; programming the TARDIS to the one place he could see the Time Lady again. The time machine gave a small jolt and landed quickly with a satisfactory clunk.

The Doctor stood behind the doors for a second, taking a deep breath to prepare himself. He pulled one door open and stepped out into a graveyard, mentally thanking the old girl for landing in just the right time and place.

The Doctor and his TARDIS now stood beneath a thick, low tree that concealed the time machine nicely. The Doctor stepped a little farther forward so that he could see the casket in front of the deep grave. Sherlock stood looking down at it as if analyzing the body inside instead of mourning the wonderful person it used to be. He obviously hasn't met her yet, thought the Doctor. The other man spun around when he heard the landing and scanned over the area of the TARDIS a few times before actually seeing it, being fooled by her small perception filter.

He took his eyes off the detective and looked at the Time Lady resting inside the shining black coffin. She looked peaceful enough, but the Doctor could hardly believe that she was gone.

The Doctor noticed out of the corner of his eye Sherlock staring at him and his TARDIS, but didn't take his eyes off of Avashta. The Doctor waited for Sherlock to walk away, which didn't take too long, before approaching the coffin. He walked slowly forward, coat billowing behind him.

Only then, when he was standing at the edge of Avashta's open grave, did the full force of her death hit him. When he knew her, she had been so bright, so positive. Now, the whole universe felt slightly gloomier without her, mourning her with the fittingly heavy, gray sky. The Doctor knew he was now truly alone, though he had thought this from the beginning. This one small, human resting place nearly broke him. It brought back memories of his family and friends all dying in the war that could only end in destruction.

The Doctor stood there in mourning until he could stand it no longer. The Time Lord stepped back from the grave and took one, final, long look at his dear sister that he seldom saw and probably never would again.
