Maybe we’ve seen flash-forwards before
Ok, so the one of the “big” things to come from the season 3 finale was the introduction of the flash-forward element to the Lost story, or was it. Yes it probably was the introduction, but consider this for a moment.
What if some of the flash-backs we have seen in previous episodes were actually flash-forwards and it just didn’t occur to us. Its probably a stretch but I’m sure I’m not the only person who has had this thought. Think about all those flash-backs we’ve already seen, do any of them jump about as being out-of-place?
