And now we basically know the plot for the next season. (SPOILER)Ben (seeing as he can't return to the island now) will attempt to get the Oceanic Six, Locke, and perhaps Walt, "Kenny Rogers", and Desmond back to the island. We should all be pretty sure that Michael is dead for good this time, but I'm not too sure about Jin.

Overall, a good second half of the 4th Season, although the writers strike made the season 16 episodes instead of the regular 24. The 5th one should be a lot better.
