I think theres gonna be a big fight between the boat mercenaries and the "others" who Ben contacted using the mirror (at least I'm theorising). I think Bens plan is for John to sneak into the underground Orcid base while everyone is distracted. It'll be interesting to see what will "move" the Island. On that note I wonder if thats why the underwater base (forgot the name) is tethered to the Island. Has the Island moved before?
Yup, it has definitely moved before. Remember the small airplane in the jungle? The one that came from Nigeria carrying Mr Eko's brother? It was a short-distance plane.
