Jordanware, what you said about his legs happens a lot throuought the story:
-Hurley, food haunting hiim, finally gets rid of it, when *gasp* The food crates fall from the sky.
-Locke, who hated helpless to move, gets his legs crushed... Remember how he was yelling at jack 'WHAT HAPPENED?'? He was miserable while handicapped.
-Charlie, after getting off the drugs and trying to shape up, finds the plane with the crates of drugs.
Theres more, but I can't think of specifics right now :/
