Its gonna be a long summer of speculation, and after a boring weds night I wanted to get peoples thoughts about this interesting scene....
In the final shot of The Incident Pt. 2 after Juliet "detonates" the bomb and the flash occurs there is a quick shot of a green eye and a gasp. I have heard a lot of people assuming this is Jacks eye and, if so, is eerily reminiscent of the Pilot scene in which Jack wakes up in the woods after the crash of flight 815. Now Im not sure chicken or the egg in LOST but could it possibly be that Jack/losties flash to the present and that scene is played out again except they were already on the Island and not on the plane. They may be able to play out everything that already happened and get a second chance to make things right A.C. (after original 815 crash). Love, life, death....etc
It also could just be that its a recurring scene and he wakes up in the woods a third time (815, 316, After Incident) and it could be 07/08 in the shadow preparing for the "war" and meeting with Sun, Locke 2.0, Ben etc.
All wild speculation at this point but I was wondering if anyone else had anything to add?
