I'm not interested in leaving it open-ended. That would just cause me frustration. I wouldn't be satisfied. What's really cool about Fringe, and one of the things we did do right, was that the way we chose to tell the story was that, with every season, there was a closure and then a new chapter. That allowed us to actually make the closure.

No love story worth telling is easy. The hills and valleys that make a relationship, in my opinion, is really a dynamic worth watching.

The way that I work is that I try to work in metaphors, and you can't write a metaphor unless you know where you're going, so I always think about the future.

Jeff always says, "In the cinema, everybody goes to sci-fi. Those are the biggest movies. But, in television, nobody wants to touch it with a barge pole." It's strange. I think it's because maybe there's a legacy of television shows that depicted sci-fi in a certain way that turns off a lot of viewers, so maybe there's a negative connotation.

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.

My favorite novels allow me to imagine the characters afterward and what happened, and that I've witnessed a really great story, where the world goes on.

What's a hero if not for its journey.
