A couple of thoughts here.
- Vincent! Now this has been the topic of much debate ever since the Season Two DVDs came out. You see, in the Season Two Finale, we saw Walt and Michael get on their boat and sail into the sunset, sans-dog. However, in the "Making of" featurette on the DVD, it showed a scene where Vincent was on the boat with them. Since Vincent hadn't yet appeared in Season Three, it was anyone's guess what really happened. It looks like the show's writers decided to go the logical route and keep Vincent on the Island (because seriously, how would he have gotten from one side of the Island to the other to get onto that boat? I mean, I've seen Homeward Bound: The Incredible Journey and all, but that was two dogs and a cat - much more realistic.)
- Disgusting! A decaying arm? That's pretty nasty. The question becomes "whose arm is that?" One of the Adam / Eve corpses from the caves? Boone? Radzinski? Desmond? I'm betting on "none of the above" for one reason:
- Key! Initially, I thought the key might have been the failsafe key from the Hatch, but upon closer examination it looks more like a traditional car / house key tied to a rabbit foot keychain (continuing the "white rabbit" theme we've seen a few times on Lost). Which means, we're due to find a new decomposing body on the Island. Sounds like a fresh storyline to me!
Two and a half weeks until Lost returns!
