... as discussed at the ComicCon this week:
- The return of Michael.
- Jack learning Claire is his half-sister.
- The reappearance of Libby.
- More of who Ben/Henry really is and what his role is on the Island.
- More of Dharma.
- A flashback involving Danielle Rousseau (which could also be for Season 5).
- The final scene of Season 3 is not the end of the whole series. Lost is not about getting off the island.
- There is a Station 6 somewhere in the Island
