The last episode of the fourth season of Lost answered many questions, but there were also a lot of twists that left us wondering about what will happen with The Island and our beloved Losties.

First of all, the main question is where The Island has disappeared. Ben mentioned something to John Locke about Dharma’s silly experiments and in the orientation video from the Orchid station, Dr. Edgar Halliwax said that the station was designed to investigate “unique properties” of the island. But there is no clue that The Island has traveled in time or in the past. Also, is this the first time when The Island is moved? Ben says to Locke that the one who moves The Island must leave it and never return there. So, we can presume this isn’t the first time when The Island is moved.

Also, when the freighter explodes, Daniel Farady is driving a boat full of people toward the beach, but there is no sign of them once the white light that surrounded The Island has disappeared.

And speaking about the freighter and the explosion, there is also a mystery what really happened to Jin. Did he survive the explosion or not? Unlike Michael, who was in the same room with the bomb, Jin has made it to the freighter’s helioport and maybe he managed to save himself from the blast.

In fact, the fate of all people who remained on The Island will be probably explained, even what happens to The Others, who are now led by John Locke.

Actually it seems like the life on the island and John Locke will be the key plots of the next season. In the end of the episode we found out that Jeremy Bentham and John Locke are one and the same person.

Jeremy Bentham has spoken with each of the six survivors and, as Jack mentions, he said that the things went very wrong on the Island. Maybe a conflict emerged between Locke and The Others? And how and why he is back? Are the six so important for The Island?

Also, another hint offered during “There's No Place Like Home Part 2 and 3” regards the partnership between Sun and Charles Widmore. Apparently, they will team up in their quest to find the new location of The Island.

From a past episode The Economist, we know that Sayid and Ben are now partners and they are fighting to stay ahead a mysterious character, referred as The Economist. At first it seemed like The Economist is linked to Charles Widmore, but maybe he has something to do with Sun also.

Also, it seems like the six are divided about their return to The Island, as Ben tells Jack that “They ALL” have to go back. In a flash-forward, Kate dreams about Claire (by the way, what Really happened to Claire) and she warns Kate not to bring Aaron back to the Island.

As you cans see, there are a lot of issues to be answered and I bet that the fifth season will be at least as thrilling as the fourth season, if not even better.
