I can't wait to see how some theories are modified by some of the interesting stuff shown and mentioned in this episode. Things that stuck out to me:

* The Dharma polar bear in Tunisia, obviously.

* The observation by Daniel Faraday (relative of Michael Faraday, perhaps?) that light "doesn't scatter quite right." This could simply have something to do with the prevalence of magnetism on the island, but I bet there's something more to it.

* Ben not knowing what the black smoke is. He could be lying of course, but I don't think he's nearly as much of a liar as people think.

* Miles apparently being able to talk to ghosts.

* Why Charlotte thought it was amazing that Claire had her baby on the island.

* Why they want Ben so badly. Was that photo taken in the 80's? It sure looked old

And whatever else I no doubt missed!
