Just my two cents but....Assuming they are all dead already that would explain why babies conceieved off the island survive on the island (They are dead too and therefore can be born) and why those concieved on the island dont make it past the second Trimester (which is when the soul supposedly enteres the physical body). Becuase there is no soul to be born.
That could be why the children are taken away, becuase they are innocents and everyone there has something to answer for???
Loved the line "its a little too hot to be heaven". LMAO.
But if thats the case, how can they be killed as Sawyer killed that guy last night???
Also remeber back in the very beginning when Jack saw his dead father on the island alive...that would tie in too.
Does anyone think the Michael and Walt aspect will ever be answered? they cant just have disappeared into the sunset on a boat can they?
