Lindelof said it was very exciting to them to be, "going into Season 5 and the fact that people are still asking [what's to come] is extraordinary." It's been announced of course that Lost will end with Season 6, and Cuse said, "We're very grateful [to ABC] for working out an end date with us. We know exactly how much time we have left to tell our story. I think that end date completely changed our storytelling approach."
Looking towards Season 5, Cuse said, "This obviously is a tricky year for us. It's like The Two Towers. This is the year that links us from the past to the final season." Cuse said that when it comes to the final season, "We've known what we wanted to do there for a long time. The challenge we have is how to we make this [coming] season exciting and engaging and put us in a place where people are excited about the last season."
