Lost Redux: Oh My David! Did We Just See a Glimpse of the Very End?

Find out what you may have missed in tonight's episode, plus exclusive scoop on what lies ahead

Oh Claire! You really have been hanging out in the wrong places, my dear.

Emilie de Ravin's final line in tonight's episode, revealing her "friend" as You Know Who, was certainly an awesome little jaw-dropper, but the biggest revelation of tonight's episode--which I just tossed at show runner Damon Lindelof--has to be this one...

WHAT LIES AHEAD (SPOILERS BELOW!):

What Is the Island? That very question will be answered in less time than you think--about halfway through the final season, according to my sources. Awesome, right? And you know who's going to help deliver the message! The fantastic, ever-young Mr. Richard Alpert (Nestor Carbonell) and of course, Jacob (Mark Pellegrino). It's a scene from the past and it's gonna be good.

So…What Is the Island? It's described as a four-letter word. There's your first clue! Shall we play Hangman? There are no A's or E's in the word…Wanna buy another vowel? Okay, one more thing I can tell you is this: The Island has to exist, from what I've been told, and more importantly, someone has to protect it. It's important to the fate of the world outside of the island.

Who's Good and Who's Evil? Jorge Garcia tells me this: "I don't think Hurley is going to be turn-able. Like I don't think he can…turn dark. I mean, it'd be interesting if there was a flash of that." Is it possible that the candidates cannot be turned? If so, what's up with Sayid?
