What an episode. I have a few thoughts:
-Is the black smoke covering something else up? (Like, was it something else looking at Eko, but covered in black smoke?)
-How the hell did Eko and his brother both end up on the island through plane crashes? Is there a connection? (I heard that this season will reveal how the plane crashed.)
- Why was Claire wearing so much makeup?
- There was an episode in the first season where Locke must have encountered the black smoke the same way Eko did. Which means the writers must know what they're doing (thank God).
- We shall call it "The Black Cloud of Judgement" from now on.
