Executive producer Jason Rothenberg made it clear just before season two premiered a couple years ago that he has a rough plan for the entire series. He knows how it will eventually end, but he doesn’t have a specific timeframe for that ending just yet.
“When I said that a couple of years ago, I had this idea for how I wanted the show to end,” Rothenberg told us. “But it was scalable and that ending could have been at the end of season three, it could be at the end of season five, it could be at the end of season eight. Those decisions are not really mine. I don’t think that this is a show that runs for 10 seasons. But I love these characters and this world so much that it’s fresh for me every year. We tell a different story every year so we don’t get bored with it. I still have an end story in mind, but I don’t know when that end is going to be and I feel very, very confident that I’ll get to tell it eventually.”
