What’s up with Walt? They made a big deal out of his specialness. If he doesn’t play some special role in the resolution I’ll be very disappointed.

Why was Libby with Hurley in the mental ward and why did she lie to him about it? The actress is now confirmed to be returning, so I hope that allows them to address this. In fact I think pretty much every is confirmed as returning as some point except for Boone’s sister, because the actress had already been scheduled for a busy movie filming schedule, though she’s willing if it can be worked out. And Danielle - Mira Furlan doesn’t want to go back to Hawaii.
What’s the smoke monster?
Who is Jacob and the Man in Black?
What happened with the Black Rock?

Why were the Others unaware of exactly what was giong on in the hatch?
OTOH, I think the Numbers question has been generally satisfactorily answered, if by the expanded universe material and not by the show itself. I also think it’s fairly obvious by this point that Adam and Eve are Rose and Bernard.
Also, I know it won’t happen and most people could care less, but there seriously needs to be a Scott and Steve centric episode. Entitled of course, “Scott and Steve are Dead” and modeled after the Hamlet spinoff of similar name…
