As far as how important the real-life resonance of the stories is, I think it must play at least a small role in the show's success, because it gives the show this sense of suspense from the fact that it seems at least plausible.

What happens is that as the scripts are rewritten and re-edited in order to make the story more compelling, you sometimes end up with what you could call a time singularity - where there's no way for everything that happens to happen in real time. It's something that you need to wink at.

Ultimately people don't watch shows because of how realistic they are. They watch them because of the same dramatic elements that have always made stories interesting. And fundamentally if those elements don't work, no amount of reality is going to be enough to keep people watching a show.

The beauty behind killing someone who no one thinks you're willing to kill is, of course, that you throw people out of their comfort zone. And that's good because you want people to be on the edge of their seats.

I think ultimately what makes the show is not the reality but the drama.

The rule, I think, is: Do your homework, learn what there is to learn about the real world, and then when you get in the room, forget it all.

I personally have more faith than the average writer in people's willingness to be complicated, and so I'm thrilled by what's happened. I'm elated at audiences' willingness to handle complexity. In some sense, I feel like my belief in what people are capable of is being validated.
