This Lost story timeline depicts the show's six seasons of narrative twisting, reality-bending and time hopping. With all the flashbacks, flashforwards, flash-sideways, moving islands, and time travel, the show's chronology can be as difficult to follow as a fast-moving smoke monster in the jungle. Even if you paid close attention to every episode, it's understandable if you had trouble keeping the sequence of events straight in your head, especially given the expansive ensemble cast that began with an intimidatingly large roster and only grew from there. There was the Heart of the Island — the mysterious, possibly magical pool at the center of the island that serves as the centerpiece of Lost's winding tale — several thousand years before Oceanic Flight 815 crashed onto the island that serves as the centerpiece of Lost's winding tale.
