Lost, Season 4, Episode 3

Another classy episode.

In the future Sayid is an assassin, not much change there then, and he's working for Ben to protect the island. I liked the flash-forward story, I didn't see him working for Ben coming, but it does makes sense. Presumably he's knocking off the Hanso organisation? Either way it makes it clear that the story is about protecting the magical island.

And just to add to the islands magical CV, it appears it's behind some time distorting field thingy-ma-jig, as well as being invisible and hard to find.

Meanwhile Locke tries to be a leader, but has clearly gone power-crazed loopy, and everyone else wonders why he's looking for an invisible cabin. Somehow Ben keeps smiling even though he seems to be tied up and beaten up most of the time.

Nice. I love the dimension that the new flash forwards add, it leaves me constantly wondering "what happened?", not "what will happen".
