Well, this episode did solve one thing for me. It verified for me the reasons why I have never liked Kate. She is a selfish, self-serving, manipulative person. Everything that she does is to benefit herself.
Yes, I know, she did go back for Claire after carjacking her and kicking her out in the middle of nowhere with nothing. It seemed so false though and I hated her more for doing it. I don't now why.

Maybe it's because I feels like it's being done just so we will like her.
Jack was another one who got on my last nerve last night. I can understand the whole "lets not trust the people who tried to kill Sayid" and all, but he just really sucks as a leader. Here is a person who couldn't even get his own alcoholic life together, yet he thinks he has the ability to run the lives and fate of others?

Just about all his decisions are bad in the outcome. Love the fact that the idiot swallowed the pill.

This should be fun.
No, I do not think that Sayid is being inhabited with Jacob. I believe that due to the fact that the water was dirty and that he really did die afterward and was given up on by the others that he is being inhabited by something else. The pill was going to kill that something else. I think that when they did this with young Ben, the water was clean and there was never any need for a pill to be taken.
Claire though; they did say that she did not take the pill and that what was inhabiting Sayid would grow and consume him like it did Claire. (Or at least that was my interpretation.) So, what is inhabiting Claire and I assume her father if it is not something that the others are cool with? Something that is on the side of Flocke and is in opposition to Jacob and The Others.
Who is good and bad though? I heard that we should all re watch that episode in the first season that had Locke and Walt playing chess on the beach. That we should listen closely to Locke's description of the white and black pieces. The producers did say that we will question ourselves in regards to who is good and who is evil. So.......is Jacob really good? When we first say Jacob on the beach with the other guy. The one who said that he really wanted to kill Jacob. I remember him saying something to Jacob about the fact that a boat was going to crash on the island, because Jacob had brought them there. He seemed almost disgusted with Jacob. Playing with people's lives for his own enjoyment. Didn't strike me as something someone "good" would do.
I'm going to reserve judgment on Flock at this time because I'm starting to wonder if maybe Jacob really is a bad guy after all. This island and the people that have ended up on it are nothing more then amusements to him. Toys that he plays with.
