I admit, the second season`s finale of LOST was amazing. I was a bit disappointed from the last episodes but this one absolutely turned my interest back. Finally, something really important happened and we found out some of the Island`s secrets and as it seems � we`ll continue to figure them out in the next season. There`s obviously no sickness on the Island and maybe the sign �quarantine� on the doors just have to keep the people in the hatches so that they continue to do their job about the experiment of Dharma Project. That doesn`t explain why Russo has killed her friends, thinking they were �sick�, but probably she just got crazy (which actually doesn`t seem very likely) or maybe there is something more that we still don`t know. Michael seems to be one of the most stupid characters but I don`t think that this is the end of his appearance. Walt has some paranormal abilities that have to be shown. I think that Michael and Walt either will decide to come back (because of Michael`s consciousness) or won`t be able to find the way and finally the ocean will bring them back to the Island. About the Others, I don`t think they will hurt Kate, Jack and Sawyer. They will probably use them for their experiments or try to make them a part of their group. Which is more interesting for me is why do the Others hide their identity? Who are they hiding from?! That`s something that I really can`t wait to find out.
