Fading
Set between "The Sound of Drums" and "Last of the Time Lords".

I woke in the middle of the night and panicked. For a terrible moment, I thought I was going to die. My body was aching all over and I was fighting for breath. When that sensation of asphyxiation had finally passed and the pain had subsided, I started listening to myself, trying to evaluate what had happened. And I noticed that no matter how hard I tried, I couldn't feel my own heartbeat. I knew it had to be there; after all, I wasn't dead, but it took me a while to finally locate that faint beating in my chest. It was as if it was fading, and then I knew: it wasn't me who was fading, it was him.
Something happened. Something bad. He's weak, and he's helpless, and there's very little hope left.
And then I did something I've never done before: I reached down that strange metaphysical cord that seems to connect us and went looking not for him but for his companion. I went looking for Martha, the only person that could perhaps save him, and the world along with him.
She was hard to find; she's shielding against everything and everyone. She needs to be inconspicuous, remain out of sight, and I guess it didn't help that she doesn't have any friendly feelings towards me – me, the one she felt was standing between her and the Doctor. But even though I was having a hard time to accept her, nothing of that matters now. He needs her, and I will do what I can to help her. She needs strength to save him, and although she is strong already, I can perhaps make her even stronger.
I don't think she'll notice my presence, and the connection is weak, but I try to reach her anyway, to somehow transmit all my determination, all my love for him, to her; everything that will add to her motivation and endurance.
I would still do anything for him.
I'll even ally myself with her to keep him from fading.
