Thanks to PaceJunkie over at The Fuselage for this info. Let's hear your speculation as to what these major reveals will be?
Next week is a Juliet flashback that has some very important reveals, from what I hear. We'll see how she came to the island, and we'll also get a much better sense of her true intentions. Cannot wait.
I can also tell you that from what I've seen and heard, there will be a pretty major reveal in nearly every episode until this season's finale, so hold onto your seat cushions and reach for that overhead oxygen, Oceanic passengers. It's gonna be a fast landing!
