[sings] I'm my own Grandpa... Iiiiii'm my own Grandpa [/sings]

Yeah, pretty much. :)

He learned it when they first got back at his father's funeral. Well, he learned he had a half sister on the same flight named Claire. He seemingly hasn't figured it out yet or I would guess he would have used it against Kate when she refused to see him/go back to the island.

Well, that would be freaky. Even for Lost. :eek:

The woman in the coma?

That's better than my guess of, "no fvcking clue." ;)

I think Ben is trying to force Kate's hand (so she feels like the only option is to return to the island) by making her think someone has a claim to Aaron.

I'm intrigued that Sawyer calls Juliet by her name rather than using a nickname.

Apparently Jack does have a clue about Aaron being his nephew.

Holy crap!

I think it's Charlotte, the woman he said he was in love with, with all of the nose bleeds.

Interesting, especially taking into account the whole "Are you sure you have only been on the island for a short time?" exchange with freaky Asian dude.

I had a guess as to who was asking for the blood tests. My guess was Jack, being someone with a legitimate familial claim, and wanting leverage to get her to the Island. So it turned out to be Ben for the same reason, I wasn't too far off.
