I dont know if this has been said or not, but what if Sayid has been taken over by smokey. he just died and there was no ash to stop smokey from getting into the temple. maybe that is why if sayid dies theyre "all in a lot of trouble". and why they needed to bring him to the temple to bring him back to life, but hurly trying to help with juiet got him there too late. then the others became distracted by trying to keep smokey out, they didnt realize he already came in and took over sayids body. any thoughts?
