The remainder of the season is all about home. We've seen that the Oceanic Six make it home, but it's not the right place for them. The last four episodes of season 4 all have a mention of home (or cabin) in the title:

• Something Nice Back Home - May 1st
• Cabin Fever - May 8th
• There's No Place Like Home Part 1 - May 15th
• There's No Place Like Home Part 2 - May 29th (two hours)
