"They Found The Plane... There Were No Survivors"

Well now, that's a horse of a different colour! Are all the shenanigans going on on the island just happening in someone's head? (The creators of the show have steadfastly maintained that's not the case!) Or has the outside world just been tricked into believing that Oceanic Flight 815 was recovered? What can this possibly mean? (I expected her to say something like, "But that flight went down over five years ago!" but certainly didn't anticipate this.)

I loved the peek into Sun and Jin's history, as well as the totally unexpected return of Eye Patch Guy (Dmitri?), raising the question: does dead really mean dead, on this island of theirs? And just what kind of island heals wounds, increases the fertility of the people on it, but then kills all expectant mothers before their third trimester? I mean, really!
