Concerning the use of time on the show, the producers did point out that just because the characters believe they’ve been on the island for a certain number of days doesn’t mean that their record of time is accurate. They also said that the mystery of Locke’s paralysis and subsequent healing upon arriving on the island would be explained scientifically this season. Damon also said there would be more involving the new underwater hatch and more Wizard of Oz references for the fans. The character of Desmond would be back, as well as more flashbacks with Libby. Any character that has been killed will not be returning to the current storyline not ruling out flashbacks and that the hieroglyphs in the hatch represent symbols that say “underworld”. We were also told that Kate would be getting romantically involved with someone this season.
Some of the creative and technical processes of the show were touched on as well by the producers where we found out that the actors usually get a script 2-3 days before shooting a scene starts. The writers do have an end point for each season so they know where they’re going as they write the individual episodes during the season. The episodes are not mapped out as they go however, to keep an organic and spontaneous growth to the writing, which allows them to add new elements and remove that which might not be working. The producers did admit as well that the pacing of the show has been influenced by the internet chat rooms resulting in a lot of what was revealed in the season 2 finale because of fans voicing for a lot more of a payoff and acceleration of the Others storyline.
Things promised in season 3 include more of an action adventure vibe and a theme will be developing of a tale of two cities between the crash survivors and the others. There will be more exploration into where Michael went at the end of season 2 now that a link to the outside world has been established. Also fans that are curious about J.J. Abrahms continued involvement would be pleased to hear he has co-written the season premiere and will direct episode 7.
