"There isn't a second season," Davies tells The Hollywood Reporter's TV's Top 5 podcast. "It was lovely. It said everything I wanted to say. The only long-running thing I've ever done is Doctor Who and that's because Doctor Who is designed to be long running. I'm not quite sure (what's next). A couple of people have contacted me asking them to mentor them, which I've done. I love doing that; both of those shows have been picked up. Strangely, I find myself as a script editor after all this time. I will start writing. I don't know how I follow something like It's a Sin. I think I'm just going to write something funny. I look at my career and I'm a bit puzzled on when I became such a tragedian, when I'm a really big laugh actually."
