Episode 9, "The Shape of Things to Come", will follow Sayid and Ben. Allegedly, this is the episode where we see how Sayid begins working for Ben in the future. There's a scene that has been filmed where Sayid is a pallbearer at a funeral. Who's funeral? Nadia's.
Next, Episode 10 is called "Something Nice Back Home" which is evidently following Jack. It's a flashforward, but somehow Christian Shepard will be making an appearance. Does his father's ghost have something to do with emo Jack? Only time will tell.
Then, Episode 11 - "Cabin Fever". A Locke centric flashback. Another incredibly peculiar guest star appearance... Well, there's a scene that will show us little Locke being born (I wonder if he had more hair as a baby than he does now?) which will include his mother, himself, and a one Richard Alpert. Woah. Anyway, the title also suggests a Jacob sighting... But who knows.
The rest is kind of dodgy in terms of what happens in what episode, however, there are a couple of cool things that have been said.
1.) The freighters AREN'T the people who rescue the O 6.
2.) There's a kiss, between a boy and a girl, off island that is supposed to be one of the best of the series. Carlton and Damon say so.
3.) There is going to be a cliffhanger at the end of the season that will leave us in a great amount of despair.
