Why You'll Love the Episodes Up Ahead: After hearing about what's to come, I cannot tell you how excited I am about the final episodes. Things are getting emotional. In a good way. You might cry watching episode 11. (Unless you're dead inside.) And everything we've seen so far is starting to feel like a warmup. Get ready!
What the Island Is: For a couple weeks now, I've been teasing that a four-letter word will be used to describe the island. It has an O, and no A's or E's. Your final clue is this: You'll learn that word next week! Episode number nine is Richard Alpert's (Nestor Carbonell) backstory and it is not to be missed.
What else you need to know (Spoilers ahead!):
- Someone we have not yet met will have an important message for Hurley next week.
- Fake Locke is going to tell Jin how he plans to get off the island, and it's pretty juicy!
- There is a "package" up ahead that might be the most butterfly-inducing reveal so far this season.
