 Since not all pieces of the wreckage were found, a few were added with greenscreen effects.The scene with Jack's speech intersperses new scenes with footage from "White Rabbit".Other continuity nods were considered, such as Paulo finding Shannon's inhaler from "Confidence Man", Nikki seeing Boone and Locke carrying shovels to excavate the hatch, and a filmed, but deleted scene where Nikki sees the sky turning purple.
