I can't tell you how exciting it was to get my hands on my favourite show - spoilers! - but it was like getting all the toys you wanted for Christmas. And best of all, I got to snatch it from the podgy fingers of that fat buffoon Rusty and take it back to the show we all knew and loved as kids.
It gives me a thrill today to hang around outside schools hearing the youngsters shouting classic Dalek lines like "Would you care for some tea?" just as we did in playgrounds in the sixties and seventies.
And though the duty officer down at the station warned me to stay away from the school gates in future, I felt I was able to persuade him of my true motives thanks to my much admired creative skills.
I knew I wanted to take the show back to its roots which is why I have been busy changing everything. You may think Rusty ruined the Cybermen, but even he was astonished at my success at wrecking the Daleks.
"Oh Stefan, I'm full of awe," he exclaimed breathlessly on the blower. "I thought your new Tardis interior was taking a few liberties but destroying the fundamental form of the Doctor Who's greatest foes is a masterstroke. I wish I'd done it."
Then he started begging to write more Who. In his dreams!
No, it is my show now and I'll decide what goes in, thank you very much indeedy-doody. I want new monsters rather than tired old fiends which is why the first thing I did was bring all the old favourites back for my first finale. And what a joy to be able to write any story with the most ridiculous cliffhanger and just get out of it with some timey-wimey nonsense.
