Here's some theories that some Lost fans (including myself) have come up with:
(Lostaway Bonnie) Yeah, I think that the camp is just for show too. I dont think they really live like that. They want our Losties to believe that they do to cover up their lab or something.
(John) Im about 95% sure that Libbys last name is Widmore. I think well know for sure next week.
(Wendy) The Others are not evil, in fact they declare themselves to be GOOD. Danielle thinks they are somehow infected and must be exterminated, but she is clearly nuts. The Others have not purposefully hurt anybody, yet they have been killed by Eko, Ana-Lucia, and Charlie. We dont know why they take people, but it seems to be for their own good (re: Claire and immunizing her and her baby), although Charlie ending up hanging from a tree was sinister.
Meanwhile, Michael WAS NOT told to kill anybody, he CHOSE to kill Ana-Lucia and Libby. He was only told to let not-Henry loose and to bring back 4 people. Michael is a bad person, sorry Michael, but you are! Its not right to kill 2 (mostly) innocent people to get your boy released from people who are taking good care of him.
(Andrew) Sawyer will be the last person to take out Michael. Ana-Lucias death shook Sawyer, but of everyone on the island, he is one of the few who would understand why Michael had to do it. Sayid, Kate, and Sawyer have all killed, for justifiable and unjustifiable reasons, before ever landing on the island.
Hurley will be the one who goes ballistic when this comes out. If Michael dies, Hurley is the one most likely to do it. Remember how Charlie dealt with Ethan.
