Visible crew/equipment: While Jin is cuffed to the wreckage, Sun points to her wrist and explains in Korean, but Sayid shouts, "The cuffs stay on!" At the start of the next shot, a crewmember's arm is seen holding the reflector screen to Sawyer's left, as he makes a sarcastic comment.
Visible crew/equipment: As Jack, Michael, and Charlie walk up to Hurley, the camera goes to the left of Hurley and you can see a road to the right of him and directly behind him a fence.

Continuity mistake: When Jack removes the paper with Kate's mugshot from the marshal's jacket pocket, in the close-up of the paper there is no writing at the top center of the paper, only at the sides.

Visible crew/equipment: When Charlie and his brother are arguing backstage, as his brother rushes out shouting "P*ss off," you can see a crew member move in the mirror on the left and the right side.
