[Jack of Arcades]

Speculation for next week (in white), including a spoiler about who's the flashback character:

<font color="white">The previews say that a connection between two people on the island will be revealed. It's a Claire flashback, so I'm guessing it'll be revealed that Claire is Jack's half-sister. Remember in S2. E20 ("Two for the Road." Ana Lucia episode) that Christian went visit his daughter in Sydney, Australia, the same place Claire is from?
