It's definitely Widmore, as they showed him in the preview to next weeks episode last night. He's a bad bad man....as we already know he's immoral trying to bribe Desmond to split, and his actions towards the man besides that fact. We saw him bidding at that auction for the "BLACKROCK" ship's log book last week too. What was that about?

It seems to me that everyone who is on that freighter is there for a different reason...I mean, Faraday/CSLewis seem to appreciate the island's scientific enigma, while Miles is there to exploit Ben and Widmore (if not on the boat, at least leading the expedition from home) is interested in the Black Rock. The heli pilot seemed to be doing it for his own reasons too, if you recall he was close to the Oceanic pilot who was supposedly flying 815.
This contributes to some confusion I have. Also, Naomi's flashback led us to believe that Abaddon was in charge, so what is the connection between Abbadon and Widmore?

Oh, and I wasn't denying that the baby is indeed Claire's son, Aaron. I was simply pointing out that Kate seems awfully careful about NOT saying his name in public...especially to Jack. I really don't think he knows. I can't wait to have more light shed on this.

exactly! Although, I'm somewhat baffled by the writers noncomittal approach to using the find815 material. While some of the info is correct, like Widmore being involved and the plane wreckage being found...nothing from the web translates into the show as I thought it would. Somewhat disappointing, but not a big deal I guess.

Widmore is Abbadon's hireling. Abbadon does not act at all like a hireling, whereas Widmore, being Mister Money, would easily throw his resources to Abbadon's will if it meant a big return on that investment.

Penny's dad is the big bad...who woulda thought?

"WHOA!" is right! My fellow John (godlovesmaggots), you hit it right on the nose.
As soon as I heard Michael/Kevin's voice (and the ominous music playing in the background) I knew it was him.

Leading us to believe that Jin was still alive was sneaky, but I think they cheated in the way they just spliced Jin's flashback with Sun's flashforward. :\

Question: Do you think that Jin is the last of the Oceanic 6? Or do they have one more to reveal?

At first, you'd think he'd be one of the six; however, if he was dead before returning (they brought his body back or he died/was killed en route), he wouldn't be since dead people make lousy survivors.

Oceanic 6 = Jack, Kate, Hugo, Sayid, Sun, and (?).

It could still be Michael.

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.
