Holy freaking crap LOST was pretty awesome this week. There was a lot of information, but I am not sure how many answers were given. There were a lot of things to talk about in the episode, but I will try to focus on just a few things in an attempt to keep from rambling incoherently as is so common when attempting to discuss LOST.
Let's make one thing clear.
Man In Black = Smoke Monster = Evil Locke = Fake Locke = Flocke
First off, I wanted to make an observation about the episode "What Kate Does". We still don't know what is possessing Sayid, but there were a lot of clues that would hint it is the same thing that Russo thought to be possessing her crew back in the day. As part of the test to see if Sayid was "infected" they electrocuted him. Not coincidentally when Sayid first met Rousseau back in season 1 she strapped him down and electrocuted him. In that meeting Rousseau was very skeptical of Sayid saying things like "I know what you are" and "you, and the others like you". At the time the meaning was unclear, but she seemed to be saying he was "infected". After shocking him a bit they start to talk about Nadia. Sayid states that she is dead because of him. Upon hearing this Rousseau completely changes her tone and touches his face, looking very close into his eyes. Like the temple dwellers, was Rousseau testing Sayid by shocking him? What was it that made him pass this test back then, that he now failed? Whatever has taken over Sayid is going to be very important to the rest of the season, and remains a pretty big mystery right now. I am confident that when we find the answer to that, we will also learn what was going on with the French crew, and possibly other inhabitants of the island. (Christian Shepherd, Claire)
