LAST EDITED ON 05-24-07 AT 01:48 PM (EST)Wait...I take back what I said up there. It's not one of Desmond's flashes.
It's Locke's.
(I'm blatantly stealing this from someone else and as claiming it as my own. )
Wasn't Locke also in the hatch with Desmond when it blew? Ever since then Desmond's had these 'flashes'. If we assume the blowing caused them (heh, "blowing) then can we safely assume that Locke has them too? And he's not saying anything?
Maybe he had this vision the whole time he was laying there in the pile o' skeletons. Maybe that's why he's so convinced they can't contact the outside world. Maybe that's why he keeps blowing important crap up.
Or maybe somebody else already brought this up in another thread and I'm just catching on now.
If not? This idea is totally mine. Yup. I just made it up right now.
