I came into this week's episode wondering if this would be the time when they finally confirmed that Jack and Claire were siblings. That was no surprise, but the clarification was nice. Of course, it looks like the characters themselves will never know unless Jack has a picture and shows it to Claire for some reason. (Or if Christian's missing corpse turns up somewhere on the island.)
I'm much more interested to see how they handle the rescue party's reunion with Jack, who seems to be having a nice time with the Others. And I am thrilled that Locke has a bit of a bone to pick with Ben, from the looks of the preview for next week's episode. That is the reunion that I am really looking forward to. Plus, we will finally get to see how Locke ended up in that wheelchair. And in two weeks I think we are getting a Nikki & Paolo flashback. Not sure how I feel about that. They've got their work cut out for them, trying to make us fall in love with those two.
