Our audience holds us to an incredibly high standard of continuity and emotional authenticity. We don't toy with that, but oftentimes we write stories, in order to spark debate. We're very determined to always give the answer. We don't want to leave a lot of things open to debate, at the end of the day.

Every one of us, as human beings, even in a committed relationship, has moments and thoughts and actions that, whether or not they share them with their loved one, tells you, as much as anything, about them as people and their relationship.

So, we're well aware of the questions that our audience is inevitably going to ask. We're well aware of how carefully they watch the show and hold us to continuity. We're certainly aware of the debates that are going to occur.

People are afraid of change. We all are. Human beings are afraid of change, but change can be good.

The fans have access to the show and the creators, even if it's not direct. I don't know any television creators that don't follow the message boards. The feedback is so immediate, to see what is working and what isn't, and what's working better than you anticipated.

We just keep making the shows that we love, and the good news is that we can never rest on our laurels, knowing that we're going to be on forever. We're constantly challenged to write the very best story that we can, week in and week out, hoping that that will allow us to keep telling more of them.

Human beings are psychologically far more afraid of bugs than they are of driving a car, whereas people get killed by cars every single day, and there is hardly ever a story of people getting killed by bugs.
