In Season 5 episode 1 we see Locke encounter the smuggler's plane that crashes on the island and eventually kills Boon. I was watching an episode from Season 2 titled the 23rd Psalm. In this episode the great Mr.Eko forces Charlie to take him to the plane which the great Mr.Eko proceeds to torch after stealing back his jewellery from his dead brother.
So back to Season 5 episode 1, after Locke is shot by Ethan he stumbles over to the plane, a plane which has definitely not been torched by the great Mr.Eko or anyone. So then we must assume that Locke is now in a time somewhere before Season 2 when they have yet to meet Henry Gale and have yet to blow up the hatch...which is the other problem because if Locke and the Sawyer group were jumping together the time period of the jump where Locke found the untorched plane coincides with Sawyer finding the exploded hatch, an event which occurred at the end of season 2 well after the great Mr.Eko torched the plane....hmmmm
Is this a gigantic clue? possibly about the consistency of the TimeLine due to time travel disruptions? Is it really like Dan says whatever happened happened, because it appears otherwise.
Also to mention, Alpert meets John at this point and speaks to him as if he had just disappeared in the first flash, as if it had been only a short period of time between the first flash and their encounter, and Alpert makes it seem like this period of when John is, is the same time as when he left, or at least after, Alpert has full knowledge of Locke disappearing, Alpert even tells Locke the it was Locke who went somewhere not Alpert. My only conclusion is that I have stumbled upon a hidden little clue, or the writer's just screwed up, they just plain forgot about the great Mr.Eko torching the plane, and wrote a scene they thought to be timeline accurate, complete with plane fallen off cliff to help us locate ourselves in time but if we use the torched plane as another marker we can really narrow down when they actually are....
but wait it doesn't match with the hatch being blown up. The writers screwed up and I am a very disappointed Lost viewer, the writers aren't the Gods I thought they were and Lost isn't as well written as I claim it to be in the faces of the naysayers.
People what do you think?!??
