I think its Jin's for 2 reasons...the first is that the producers have said it is Jin's in the podcast (unless they're lying) and the second is that I'm tired of everything being a freaking con...if every single thing that Ben, Juliet, and the rest of the Others have ever said is a big master con, I'm really going to be disappointed in this show. I have to believe some of what they are saying is true...I don't like feeling that I'm the one being conned, when every "answer" we are given may not be an actual answer.
