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.
Continuity mistake: When Michael is finished talking with his ex and Walt at a park, over his right shoulder can be seen a dark-haired woman in a black halter top and green slacks walking away. The camera shifts to the opposite view where Michael is looking, and the same woman is seen leaving a newsstand in front of the ex. (00:39:00)
Other mistake: In the scene with Sawyer and Michael drifting on the pontoon, where Michael is crying, you briefly see a boat with a mast in the background in one shot over Sawyer's right shoulder as he faces the screen, just before he says "Are you allright Mike?".
Continuity mistake: When Mike and Sawyer climb onto the pontoon (after Mike shoots the shark) there is a long wooden beam protruding to the left of the pontoon. In the next shot (morning, where Mike is crying) the beam protrudes the other way.
Answer: He was eating a peice of an orange with the skin still on.
