So if Ben assumed the identity of someone else, I'm pretty sure their family would be pissed off and it would have been over the news. The 'Oceanic 6' did leak over the net, but I think Jin isn't one of them because in this episode that was his flashback, and Sun's flashforward. We can also rule out Desmond because he came to the island by boat, but there's no saying whether he got off or not. There's also Juliet. I think the 6th member is yet to be revealed, and it will be someone completely unexpected.
