I was looking at lostepia's timeline which had a reference to Rousseau's friend Montand that lost his arm and then was subsequently killed by the smoke monster after Rousseau's party landed on the island in "This Place is Death". That made me remember the skeletons in the cave when Desmond is lowered down into it.
This made me go back and look out of curiousity, at first there is a shot with two skeletons, then it shows one more that looks like it could be missing it's left arm. I don't have the time right now to go see which arm the guy lost, but does anyone think that that skeleton could have been Montand's?
It might be a stretch, but it's something I have not seen anyone mention.
