The way it is panning out it seems that we are starting to see the "future-creating stints" made by the losties that are back in '77, (Sayid shooting Ben...Kate taking Ben to Alpert) so it looks like they must all have a role to take. So that would leave Hurley and Jack....oh..i nearly forgot, Desmond who Elouise told that the island was not done with him. Whos "stint" is next then? They're clearly there to do something. One thing im sure of is that Jack's role in this mind bafflin' timeline will be HUGE. What could it be? Any ideas? After all... I AM JACOB..
