Also from reading other boards about lost I have these questions for you. In the scene from Locke's apartment it has been speculated that he has a framed set of patches on his wall that suggest that he was in the Military special forces which could explain his knowledge of knives, guns, and explosives. I mean really if you happened to find a block of c-4 with the detonator could you rig it to explode on a time delay the way he did with the submarine last night? Also on the subject of the submarine, did he really blow it up? I mean when they found him on the peir he was soaking wet suggesting he had been in the water for some reason. Could'nt he have just set the charge inside the sub and done as much damage? Or did he pilot the sub somewhere else and then blow up the pier to make it look like he sank the sub? He would have got wet swimming back to the pier from wherever he stashed the sub.
Have fun.
