I'm really trying to just keep this internal, and be faithful to the story and the characters, and keep 99.9% of my brain there, serving the story. It's a great network. It's the golden network of cable, so it's totally an honor to be there and tell this story, but I try not to think about anything beyond that.

The most surprising thing to me is what an incredibly intense effort it's been to create a world from the ground up. I had run a show that had already existed and had been created by the show-runner, Meredith [Stiehm]. It's a very different experience to come in at ground zero and meet people and assemble the cast and crew. As a group and as a family, we're creating this world.

I used to live in New York and now I live in L.A., and somehow I've become a different person because of the air and what I see every day, and I think we all do.

And as cynical and jaded as many have become, you see the heroic nature of cops, who put aside a lot of their own personal concerns and their families to speak for the dead, which is a sacred thing. Over time there is this thing in them that is very powerful and interesting and provocative to me.

Seattle is beautiful. You look at the sky and it's one of the most beautiful skies in the world, and then there's the Puget Sound, which will kill you, if you fall into it, but it's also beautiful. Seattle is a city of contradictions. It's the most liberal and most literate city in America, and it has Starbucks and [Bill] Gates, but it's also where the Green River killer hunted women and where the runaway population is just shocking when you walk the streets. Within the same city, there's darkness and light.

I am endlessly fascinated by this notion that everyone has a secret. Some of our secrets are tiny, small things, and some of them are huge. Given that reality of the human condition, that's what our characters will go through. There will be some things where you'll just be like, "What the hell! How the hell did that happen?"

Because we spent so much time in the writer's room, not even talking about where it goes, but just who the people are in our world, we could find all those unexpected moments and twists and turns that we didn't even see ourselves.
