LAST EDITED ON 10-12-05 AT 07:29 PM (EST)Just before Jack chased Desmond out into the woods, his eyes locked on a personal photo that Desmond had displayed in Hatchland.
My first thought was that this was Jack's wife Sarah, which would be very interesting.

It's a blonde woman, but I'm not sure it looks enough like Sarah.
It MIGHT be the woman who bombed the raft. Then again, that might be Dr. Karen deGroot of the Dharma Inititative...

And the whole thing may be a red herring. But it certainly seemed as if Jack paused on that photo, recognized something, and chased Desmond out into the woods. And the ensuing conversation was about Jack's wife. Sort of.
Edited to correct the image problems. Oops.
