De uma entrevista com os showrunners :
Carroll: How much of what we’re learning now in season six was figured out in the first season, versus, say, a month ago?
Lindelof: There’s no empirical answer to that question. The way we got through the first season was, if we introduced a mystery, like a polar bear running through the jungle, or a hatch that was discovered in the ground, we had to know what the resolution of that specific mystery was. And in the episode-to-episode writing of the show there’s an enormous amount of discovery. I think one of the most profound lessons I’ve learned over time as a show runner is that the more you listen to the show, the better your show. We watched our characters interact, and that would influence how we put them together.

Carroll: It’s one thing to have a hypothesis and even figure out what the predictions of that theory are, but then it’s going to be shaped by what you observe in the universe.
Lindelof: We have to have the answers to the mysteries so that there is something to work towards, but what we don’t have are the stories. J.K. Rowling can sit down and say, here’s how Harry Potter’s parents were killed, and here’s who killed them, but how am I going to reveal that information to the audience in the most emotionally impactful way? So we know what we want to do, but we have very little idea of how and when we’re going to do it.
Não mencionado nesta entrevista em particular é o fato de que JJ Abrams originalmente trabalhou com Lindelof para criar a "Bíblia" do programa, que é tipicamente uma visão geral do mundo, personagens, enredos gerais e quaisquer detalhes cruciais importantes.
