We can't say anything, but just remember that, on Fringe, nothing is as it seems. There's always a little more to the story behind the story. He's definitely a large part, going forward. A lot of things will come full circle.

What was so great about Lost was that it came to the front door as a drama that was straight-up and really gave you the sci-fi underneath it all. It backed into sci-fi show, at least in my opinion. As soon as they got hooked, they were like, "Okay, I'm there."

Fortunately, at the end of every season, we close the chapter and start anew. That's the language of the series now, so it can organically come to a conclusion that we love.

You realize that everything is a moving budget, and sometimes you've got to borrow from Peter to pay Paul, to make it happen.

It's a sci-fi show on network television, and everybody knows that it's an amazing feat that we've been on for so many years. The fans, the press and everyone has been so incredibly kind and so incredibly supportive that we feel like it's a success, in any way, shape or form. It's an expensive canvas.

What's a hero if not for its journey.

First of all, directing was the most incredible experience. When you run a television show, directing is something that not many people actually get the time to do because you're so consumed with everything that's going on. You can't just disappear.
