Haven't been on here in a while, but after watching the latest Doctor Who episodes I couldn't resist. I hope you enjoy! I've edited a few things to improve the story thanks to comments from Jessiekat22 and j1ack. Also, the symbols I put at the end are as close as I could manage to the Doctor's name as has been revealed in an old episode of DW.

I should have known I'd end up here. I should have known that protesting the space suit had been in control, not me, would never have worked. I should have known that naming Madame Kovarian, a strange woman wearing an eye patch whom I barely remember, was futile. So many memories of my childhood are blurred, sometimes with months missing at a time, and I know she was there. I know it's because of the Silence – but I can't remember what the Silence are, so how could I explain that to the court? They had evidence, pure and simple, that I was in the spacesuit and I was the one who killed the Doctor. I couldn't dispute that I was in the suit – I was, and everyone knew it. And of course I couldn't explain that the Doctor wasn't truly dead. But I never expected it to end like this. A lifetime sentence of imprisonment.

It's worth it, of course. It's worth me being in jail for the rest of my life so that the Doctor lives. But… so many regrets. All those years I spent studying archaeology so I would be able to find him again, and almost all of it gone to waste. I saw him a few more times before Lake Silencio, of course, but not enough. Never enough. And now… will I ever see him again? He needs to hide, and I am stuck in this prison cell.

"Doctor Song." The voice jarred me out of my reverie and I turned, to see a guard standing at my door. "You have a letter." He dropped it through the bars and onto the floor, then turned to march away. The envelope was blue; a strangely familiar shade of blue. I dropped to my knees the moment I recognised it and tore open the envelope, hastily unfolding the single sheet of paper inside. The paper felt almost silky beneath my fingers and I realised it was a special type of psychic paper - psychic paper that could only be read by me. The words emerged as I picked it up and I saw that his handwriting was neat and careful. It was the opposite of what I had expected from that crazy, wonderful man, but I knew it was him.

River,

Or maybe I should call you Melody? I know this is still early for you.

I wish I could be there with you tonight. It's your first night in prison. Your first night serving a sentence you do not deserve, and it is my fault. I knew it was inevitable from the moment Madame Kovarian stole you from Amy and Rory to turn you into a weapon, and despite my words at the time I am ever grateful at how much you tried to resist my death.

I wish I could be there, but I cannot. It would be too suspicious to visit you so soon, my love. Do not despair, though, I will come. I only wish I could take you away from your prison forever. Not for one moment should you think that you will be left there alone. We shall see each other again. I wish I could explain further, but, as always, spoilers.

I love you River Song, Melody Pond. Our adventures are not at an end. We shall run through the universe together, all because you are serving this time for me. I would tell you to wait for me, but I know you are too impatient to just wait.

Your love,

The Doctor

I squinted at the last few symbols at the end of the letter. It was High Gallifreyan, and mine was certainly rusty. It had been over a year since I'd studied it. Finally, though, I understood. The Doctor's name. At last. Not a pretence like at our wedding to avoid suspicion, but the real thing. So simple, so elegant, so… him. With newly found energy, I stood and made my way towards the locked door. Examining the lock, I began to smile. The Doctor was right. There was no way I was simply going to wait for him to arrive. I was not going to languish in my prison cell obediently.

I am River Song, daughter of Amy Pond and Rory Williams, wife of the Doctor. I will find my way out of this place, and then I will find him.
