The first show of Season 4 is number 70 with an even dozen left to go. We will finish watching all the previous shows a week and a day before Season 5 starts. It would have been perfect, finishing up the day before, had ABC not moved the season premier on me.
This flashforward (which becomes the theme for this season) concerns Hurley and the fact that he keeps seeing his dead friend Charlie from the island. Charlie has something to tell Hurley, but Hurley doesn’t want to hear it, he has to go back to the island.
Real time on the island the Losties split into two factions, most follow Jack in his quest to get everyone rescued by the people on the freighter off shore. While some choose to follow Locke to the Others old home, the Barracks, in an effort to avoid the freighter folks because, they like Ben, think that they are coming to kill everyone.
