wow this whole time traveling thing is starting to make A LOT of things from the past come together.
now we know why all of the "others" want Locke to be the one.
it also seems that now the "dead people" on the island may not have been dead at all, but were rather stuck in this time traveling sequence as well.
also if you remember, i tihnk the "dead people" that have been seen back home (claire and charlie) were ones who died on the island (or near it in the radius in charlies case). coincidence?
