Warning: the following interview with producers Carlton Cuse and Damon Lindelof focus on the new narrative structure introduced on last night's Lost season premiere.

If you haven't watched it... drop everything you are doing and fire up that DVR and/or read through our thorough review of "LA X" right this very instant! The episode is a doozy.

The following interview with Cuse and Lindelof focuses on what was likely the most controversial aspect of the premiere: it's new narrative structure, which we've dubbed as "flash parallels."

But were the scenes on flight 815 parallels? A rebooted timeline? We'll have to keep watching to find out for sure, but here's a summary of what the producers told Entertainment Weekly on the subject...

• The simultaneous timelines have been planned for a couple years.
• Said Cuse: "The big question of the season is going to be: How do these [two timelines] reconcile?"
• Viewers should go back and take close looks at the differences between this flight 815 scene and the one we saw on the pilot episode.
• Whether or not Jughead is what created the new timeline is a "big mystery" right now.
• Lindelof said they have replaced the trademark “whoosh!” sound effect marking the segue between Island present story and flashbacks or flash-forwards, thereby calling conspicuous attention to the relationship between the Island world and the parallel world.
• He's also quick to say: "Don’t use the phrase “alternate reality,” because to call one of them an “alternate reality” is to infer that one of them isn’t real, or one of them is real and the other is the alternate to being real."

In conclusion, Lindelof summarized, "Season 6 is not about time travel. It’s about the implications, the aftermath, and the causality of trying to change the past."

Can that actually be done? It doesn't seem that way, as even new developments in 2004 haven't stopped the characters from arriving at their destination in 2007. At least we don't think they have.

It's all rather unclear at this point, but that's what we love about Lost, isn't? Let's just sit back and enjoy this utterly unique, incredibly dense and well-produced drama for what it is: the best show we'll ever watch.
