Leaving island in the past = Strange Results by Daniel

I don't think that we have received sufficient answers to what happened in the three years between the flashbacks and present day events of lafleur. Most importantly, why did they stay more than two weeks, why were they allowed to stay more than two weeks, and did any of them attempt to leave during that time? It doesn't make sense for all of them, especially Juliet and Miles, to put up with staying. The only one we knew who left was Faraday, who had suddenly renegged on his whatever happened, happened theory when he came back. I know this was a retcon and he was meant to be working in the orchid, but we still have no idea what happens, and since the time travel is a result of the island moving, surely it wouldn't be a gateway to the past of the rest of the world.

I believe that whenever one of the 77 losties left on the sub, they disappeared. They woke up floating in the sea in some time period, possibly their native time period. However since they are destined to be on the island, strange things happen that lead them back, exactly when they left. When faraday does this, he finds evidence that he has permanently changed the future from his time in the past. Sawyer tried to do this to stop his family from being murdered, but it led to him discovering that "what's done is done". Juliet didn't, which is why she thinks nothing of getting on the sub in "The Incident". Miles accompanied Sawyer on his journey, in case anything happened.

This will be the basis for a Miles centric episode (one of the reasons I came up with this theory). It will fill in all the gaps of the time with dharma and all the time travel technicalities, while the present day events will involve miles analysing key dead bodies including the Real Locke and Adam and eve. Analysing the real Locke's body will give him a dream that will lead him on a journey to a spot on the island, similar to the episodes "?" and "Deus ex Machina". At the end of the episode, he will be killed (Miles probably doesn't have much of a place in the series' future), possibly from a brain hemmorhage after analysing the Adam and Eve corpses (if that's a very significant mystery, but that's another theory).
