While it's yet to be declared as such, I believe that Aaron is the last of the Oceanic Six. The news media (who likely created the term) wouldn't care whether he was on the manifest or not, he was the sixth one "alive and rescued".

Also, I don't believe for a second that Jin is dead. Apparently the date on his tombstone is the date of the 815 crash. Further, those who are still alive on the island (in the future) are listed as 'deceased' to the rest of the world. So they would all have tombstones, because their friends and family would have had funerals, believing them to be dead. Sun would have had to have done SOMETHING to keep up the cover story. That's why she was saying "I miss you so much."

Think about it - if you lose someone you love to death, it's hard and you grieve, but eventually you move on. But, imagine if your lover was stuck on an island that NOBODY ELSE knows about and you CANNOT REACH. That would be worse than losing someone to death. It would be a living, daily emotional torture with no resolution in sight.

I'm really curious what the Captain might have been lying about...seeing as all indications tell us 'the captain is not to be trusted'.

notice how George was the first on the freighter to be contacted via the Sat-Phone, then Regina--who said that George was "unavailable" (presumably after his temporal-rift side-effects had manifested). Now both are dead; not that I think that this bears anything ominous for anyone who has used the Sat-Phone. I just thought I'd point that out.

not so... some of the crew (was it Faraday?) even warned them not to trust the captain.

Last night's episode was great! I felt like it actually answered some of my top questions without throwing in TOO MANY more. GREAT! NOw.....who killed Rouseau!?
