I've been watching since season 1, but this episode threw me off.
it was a good one - major plot explosion at the end when finding out that Ben is part of some organization that planned for the plane to crash on the island to perform human testing, and he/they got 325 bodies to fake the deaths of every one board the plane - according to the boat captain who had the black box from the plane and was saying this all to Sayed and Desmond. Course keep in mind they had gotten that note earlier about not trusting the captn.
and the flash forwarding to the 6 surviviors is really wierd, but it does tie into many things that are currently going on
Its a twisted show and can make you think at times but you really gotta watch ALL the episodes to be able to keep up and make sense of whats going on during any episode because they all tie in together
