So im semi new to lost, but the show kicks ass,

btw i dont know if you guys have talked about this or not, but i have a feeling that the submarine plays a factor, now i may be looking into it too much but i think locke hid the sub somewhere else and instead blew up the dock.

Also i think that the scene with the p-bear on the desert is just another dharma site.

The plane in the water was staged, obviously, by dharma to put all this to rest so they could go in without any attention.
