Just received this, as with all rumours take with a pinch or sometimes large handfuls of salt. It does however confirm a previous spoiler about the submarine being blown up. Just got back from Hawaii, Kualua Ranch is where they film lost. Was invited guest...this spoiler is huge well here you go Michael is back he was with the cast in crew talking. The scene I saw was Locke and Mate walking on get this a submarine and they explode it. That's right a submarine. It was a night scene and they used about 15 gallons of gas for this particular scene.
