Continuity mistake: When Kate and Sawyer find the deceased crash victims underwater, as Sawyer takes the man's wallet and heads for the surface the corpse's tie floats up freely, his suit jacket is pulled way up, and his legs are spread apart. Yet, when Sawyer and Kate go back for the case, the neat tie and suit are on properly, and now the corpse's legs are suddenly crossed, albeit in a twisted sort of way. There are other changes in both the female and male corpses' positions between shots. (00:05:20 - 00:05:50)
Continuity mistake: When Jack joins Rose on the beach, he places a blue blanket round her shoulders. In the following shots while they sit together, until Rose and Jack stand up, the blanket moves around quite a bit, jumping on and off Rose's shoulders depending on camera angle.
Continuity mistake: When Claire visits the psychic for the second time, she is seen giving him AUS $100 (1 $50 note (yellow note) two $20 notes (red notes), and one $10 note (blue note)) but after the session she asks for her $200 back ($100 notes are green, and there is no sign of any green notes). (00:24:35)
Continuity mistake: Once Sun leaves the bathroom, Jin's hands begin to shake as he washes the blood off, in fact there is much more blood on his hands now to wash off. Suddenly there is a silver/red soap dispenser on the right of the faucet (this isn't the gold/red one on the left), where the bar of soap was earlier, and there are also two large white towels hanging on the bar, whereas there was only one in all the previous shots. The early part of this flashback is in "House of Rising Sun" and the additional last shot was filmed at a later date. (00:25:25)
Continuity mistake: When Claire gets to Kate and sits down with her talking to her, Kate gives her a bottle of water. Then Claire asks "What are you doing?" and then puts the bottle to her mouth. When it cuts from behind her she has suddenly lowered the bottle. (00:08:40)
Continuity mistake: In this episode Jack works on an old crippled man to try and perform another "miracle." Remember, this is supposed to be in Jack's past. When he's looking at the x-rays in the beginning, take a look at the dates on them. They're November 16, 2005. In the last episode of season 2, Desmond says that the plane crashed in September 2004.
Continuity mistake: When Walt notices the pillar of black smoke, in the overhead shot everyone gathers well behind the raft, including Claire, who was just sitting in front of the bushes in the previous shot. However, in the next shot, all the survivors are now gathered at the side of the raft. (00:08:30)
Continuity mistake: In the garage, when Haddad tells Essam and Sayid to stay relaxed and focused, his collared shirt is on properly, but in the next shot, as he says, "Drive with the windows down," the shirt is off his right shoulder. This happens again when Essam takes the gun. (00:34:40)
Continuity mistake: When Kate and Sawyer go underwater to retrieve the case, in a close-up it is easy to see that the male corpse is barefoot. But in a following close-up, when Sawyer swims up with the Halliburton case - just as the words "Production Designer Carlos Barbosa" appear onscreen - in this specific shot the man is actually wearing a black shoe on his left foot. (00:06:15)
Continuity mistake: When Jack hangs off the cliff, he grips a vine covered in a multitude of leaves in the wideshots, but in the three tight close-ups his hand is dramatically shown slipping down a vine, without any leaves on or around it. He also remains at the same height position the entire time. (00:21:30)
Continuity mistake: As Jack performs CPR on Charlie, in the close-ups of Charlie, the twine lies curled under Charlie's head and his right hand rests on his chest, but in all the wideshots the long twine is spread all the way out, under/behind Charlie's head, and his right arm is stretched out to his side.
