This Reflection of Me: Thoughts on writing chapter 2

I've written chapter 1 of this new story this weekend, and it struck me that the Master has become really cold and mean-spirited. I know that some of you were not big fans of Anne and her relationship with the Master, but her loss together with the realization of Rassilon's return has really made a lasting scar on him. The previous two stories were all about how the Master tried to do good, but had failed miserably in the end. In this story, it seems that he doesn't even try any more. The drums have returned and all he's hungering for is taking his revenge on Rassilon. By the time the Doctor realizes this, it is going to be too late.
