The gag reel begins with an introduction by J.J. Abrams, who apologizes for not being able to attend the show's wrap party. He then says he is looking forward to watching the gag reel, and presses play on his television. However, the opening titles to LOST is shown. He stops the recording and calls someone, asking where the gag reel is.
The film then cuts to a child running through a parking lot carrying a tape. A subtitle reads "The Babies of Alias". The child reaches the set of APO, where they are other children sitting on chairs. They reach a television monitor and put the tape in and watch the gag reel, when then plays.
