This is a good point.
It's clearly developing into the eternal 'good vs evil' struggle, and everyone is taking sides. I'm still not sure how Whitmore ties into that. They are looking for Jacob's replacement (Hurley or Jack I'm guessing), the Smoke is taking the form of Locke, and I'm wondering now if Richard is going to be 'replaced', possibly by Hurley. I can't help but think Sayid will be playing a huge role in the end of this whole mess after his lack of reaction to Kate being attacked. Also, it will be interesting to see where Sawyer ends up. Possibly the alternate reality contains clues to all of this?
And I miss Desmond.
