Plot hole: Sawyer pulls the bullet out with his bare hands, we are led to believe, through the cut the bullet made. When you are shot, the flesh immediately seals up, meaning you would need a knife or something like that to get it out. Sawyer only had the gun, as he could not have hidden the knife AND the gun.
Visible crew/equipment: As the "rescue" boat nears the raft with Jin, Sawyer, Michael and Walt, it has a spotlight shining on the four aboard the raft. That spotlight is the only light source in the area, yet the boat is bathed in bright light from behind, which also reflects in the boat's pole. (01:12:00)Super Grover
Continuity mistake: In the first shot of Locke sitting in the wheelchair, in the airport lounge, he sits alone directly in front of the long rows of chairs. However, in the next overhead shot, the airline steward is at Locke's side as he sits near the large windows, nowhere near the chairs. (01:03:15)Super Grover
Continuity mistake: In the Oceanic Int'l departure lounge, Locke sits in his wheelchair near the large window, with the doomed plane in the distance. The attendant's desk is on the left, but the black lounge chairs, which are normally situated toward the center of the lounge, are gone in this shot; the chairs at the end of each row should be visible at this angle. These chairs are also seen when Hurley crashes the scooter into them. (01:03:15)Super Grover
Continuity mistake: Just before Michael says "You're going to pull the bullet out with your bare hands?", Sawyer's hair is very wet and pulled back, as if it were in a pony tail. When the camera switches back to Sawyer saying "You got a better idea?" his hair is a lot drier and covering his face. In the next shot, it is pulled back again.Sam Johnson
Continuity mistake: In S.O.S., Locke is trying to remember the map he saw on the blast door. He ignores the blaring alarm until Jack reminds him, and Locke inputs the code and hits EXECUTE. The camera cuts to a shot of the numbers resetting, and then back to Locke, and he takes his finger off the EXECUTE button a second time.
Continuity mistake: Just after Sayid has woken Sawyer up by throwing water in his face, there is a shot of Sayid from behind the tree Sawyer is tied to, and you can see a bit of Sawyer's hair. However, it is hardly wet, if at all, and when the camera cuts back to Sawyer his hair is drenched again.
Continuity mistake: After Sawyer admits to Kate that he doesn't have the inhalers, Sayid and he get into a tussle. In the first shot, the back of Sayid's white shirt is fairly clean as he is standing, but in the next wider shot the back is completely filthy - before he and Sawyer ever even hit the ground.

Visible crew/equipment: When Sawyer finds his blue tarp that the boar ran off with earlier, Sawyer hears the whispers, then the boar reappears and chases him. When the mean old boar flips Sawyer over, the chain link fence (used for the stunt) is clearly visible beyond the grass, at the top right corner of the screen. (Also seen on Disc 7.)
