LAST EDITED ON 05-24-07 AT 01:19 PM (EST)It was interesting that the wound brought back the paralysis. It left me thinking that he's not so much "healed" as "protected/charmed". In his physically weakened state after the gunshot, the paralysis came back, almost as if this protection had been undone. Jacob/The Island/whatever had to restore the protection on his whole body, which now included both the paralysis and the gunshot.
OR the island really did heal the gunshot, but the paralysis was always a matter of willpower and not physical healing.
Regardless, I think he's OK now and will be as long as he stays on the island. If he leaves the island's protection, there's no doubt in my mind that the paralysis will return. As to the gunshot? Well it would be silly to have the wound open up if he left, but it's a far-fetched explanation as to why it might be him in the coffin. (Not that I think it's him in the coffin. I don't. I think it's Sawyer.)
