Well, maybe, but then tell me what the obvious, uncomplicated deal is with the woman's bombshell at the end of the episode that the wreckage of flight 815 had been found and that there were no survivors.
The simple, uncomplicated answer to that (it would seem to me) is that since we know that there are survivors, she's lying.
The problem with that, of course, is that she apparently crashed a helicopter and damned near killed herself just to tell that lie.
I suppose it's possible that the passenger and tail sections of the plane were recovered from the ocean...but that begs the question of why the cockpit section couldn't be located on the island.
Nah, I think things ARE complicated. There's way too much coincidence and weirdness going on on that island for things to be exactly what they seem.
