At Comic Con, Lost showrunners Damon Lindelof and Carlton Cuse crashed EW’s Totally Lost: One Year Later panel and brought with them a never-before-seen clip, an alternate ending to the pivotal season one finale. Lindelof and Cuse ultimately decided against keeping this scene in the finale “for fear that it revealed too much about how the series would eventually end.” Watch it, and decide for yourself whether or not it was wise to remove it.
Psht, and people thought they were making it all up as they were going along!
