This was amazing episode. The last one was really mood ruiner but this one - it was huge, massive, so much mystery, action and.. I do not know. I have never felt much good feelings about Ben but this episode really opened him as a person who does have feelings, who is human.
This episode answers for us why Sayid works for Ben and even thought I am not sure if Ben was not the person who killed Nadia in the first place because he is like little child - trying to get everything he wants with any means necessary
The fight on the island, that smoke monster.. executing Alex (what was cruel.. killing her and Rousseaux was very cruel) all the lies what surround them. It was such a massive and very good episode.
I liked it.. a lot..
