at the beginning of the seaseon 5 finale jacob is talking to a man that is yet to be explained. jacob was wearing white the other man black (good and evil?) he says that one day i will kill you clearly there is a feud between the 2 men. present day that man dressed in black is now in the form of john lockes body, clearly this man has the ability to aquire a dead body and use it to live. jacob looks the same as he did during the crash of the black rock he hasnt aged this is because he too has the same ability to live inside of a dead body and for some reason these dead bodies so not age with death . noticed how richard alpert hasnt aged ? could this mean there is a third person involved in the feud ?. I think this is the case because when the black rock crashed on the island (richard on board) the man in black said "i guess well have to find out" refering to what they were doing there. i think the black rock fired! cannons at the statue leading to why the foot and body are in different places. resorting in a fight between the man in black other spirits and members of the black rock. richard fell victimch and so did the body of the man in black some other spirit took over the body of richard and the man in black ran freely as a spirit until he found lockes body this is the "loop hole". The first ever episode of lost christian shepherds body was also taken over by another spirit but the once morphed into christian he took the dead christian body and hid it so that jack wouldnt find out and would believe it is him still alive. the spirit that took over locke could not act quick enough to hide the body because it was being hevealy gaurded by illana in the early stages of season 5 when locke triend to get the crate from them. the body of jacob was stabbed to death by ben, jacob is certainly not dead and forever unless bodies are not available on the island he will be alive, he is a god, n! ot just any god he was origionally the god of the egyptian sat! ue which he now lives in. this is why in the present day jacob still makes those ancient egyptian scripts on the material that he weaves. so whos the next body he will use?. im thinking either mr eko or daniel faraday allthough farady is killed in 1977 so i doubt it mr eko on the other hand was a very religious man and i allways thought his time on the island was cut short and he needs more time. i thought of faraday because he has allways seemed to have a purpose or destiny on the island. one one more question that i havent answerd yet is who is coming?. i think that it is some of jacobs fellow egyptian gods are coming to destroy the spirit inside lockes body for good and leave the island at peace at last. but someone answer me this regarding my theory. do you think the smoke monster is the spirit of the evil guy or do you think it is on the good side of things on the island ???
