You should download the Official Lost Podcasts... they explain a lot and you don't actually need an iPod or iTunes to get it.

They explain why they do so many reruns and that they know where the story is going for the most part, but not always. It's really entertaining, IMHO.

I didn't mind seeing Shannon in her bikini last night though.
