A/N- Here's a take on the Master's thoughts during his final moments in Last of the Time Lords. As always any feedback would be most appreciated, every little helps. :)

He talked her out of it, the fool, he thinks I'm beaten
Da Dum
But the plan will carry on, I will never be defeated.
Da Dum
What's he planning for me though?
Da Dum
Jack speaking up, oh it was a fun year with him. The amount of pain I put him through.
Da Dum
He can't be serious. He's going to…keep me.
Da Dum
I can't believe it, I am Koshei! I am the Master! I am not some sort of pet!
Da Dum
I wasn't expecting that! The pain as Lucy shoots me, as she betrays, is unbearable, now I know how he felt in San Francisco.
Da Dum
And then he's running and catching me.
Da Dum
The irony that it was another women that caused my death doesn't escape me and I tell him as much
Da Dum
He's making excuses, saying he didn't see her.
Da Dum
The world's getting dimmer by the moment, he must be so happy holding me as I die.
Da Dum
I can feel the change coming but I push it back and cancel it. Let him suffer some more, thinking he's the last of us, I'll return one day, I always do.
Da Dum
I'd rather die then spend eternity trapped with him.
Da Dum
It's not ending though, no matter what he thinks. I've made plans, my Cult of Saxon will succeed. They must, now that I'm gone. My Cult...and the Books of Saxon will bring me back when the time is right.
Da Dum
Using the last of our race trick won't work, the pain's worth it just to see him losing control, begging me to change.
Da Dum
The pains almost unbearable, but I grim and bear it by holding onto the single thought; I win.
Da Dum
My only regret is that the mystery never got solved, there was always that nagging feeling that the drums weren't there before the Time War.
Da Dum
But it's always been there! I know it has!
Da Dum
I've got to ask him, those drums. Those mysterious wonderful drums.
Da Dum
Will they...will it stop?
Da Dum
Will the drumming stop?
Da Dum
Goodbye for now Doctor
Da Dum….
