Ok , the God/Religion references last night were due to Echo's flashback , his story and his quest to find peace ,forgiveness or whatever . I do not see where the subject comes up again except for Charlie and that one reference Ben asking Jack if he believes in God . My point is there are sooooooooo many other back stories and happenings that have no God in them . so why all the emphisis about that one issue .... But the point about life , death and God are all connected is true . And the other thing bout the smoke being Jacks dad ,Walt etc..... Jack found his dad's coffin , but the body was NOT there , when Echo got to the plane , Nemi's body was NOT there . So my thought is , where were they ? Who or what were Jack and Echo chasing ? I don't know if I buy the smoke imaging thing .
