Ep 1. Because You Left

Because You Left is the premiere episode of Season 5 of the hit television show Lost. It picks up where Season 4 left off, with the Oceanic Six (Jack, Kate, Hurley, Sayid, Sun, and Aaron) rescued from the island and living their lives off the island.

However, as the episode progresses, it becomes clear that all is not well. The island, it seems, is not done with them yet. The episode begins with a man in Tunisia who appears to be experiencing time travel, as he is bouncing between different eras seemingly at random. The man ultimately ends up in the Sahara Desert, where he is confronted by a group of armed men.

Meanwhile, back in the real world, the Oceanic Six are all grappling with their own issues. Jack is struggling with addiction and is in a rough place emotionally, while Kate is on the run from the law and trying to keep Aaron safe. Hurley is paranoid and convinced that everyone is after him because of his connection to the island, while Sayid is working as a hitman. Sun is determined to get revenge on the people responsible for her husband's death and is working with Charles Widmore to do so.

As the episode progresses, it becomes increasingly clear that something is wrong. The island is experiencing strange electromagnetic phenomena, and time itself appears to be out of sync. There are flashes of light and sound, and characters are thrown forward and backward in time seemingly at random. The Oceanic Six begin to realize that they may have made a mistake in leaving the island and that their actions have had disastrous consequences.

Throughout the episode, we are introduced to a number of new characters, including a mysterious woman named Ellie who seems to know more about the island than she lets on. We also see the return of some familiar faces, including Daniel Faraday, who appears to be attempting to fix the timeline and prevent catastrophe.

Overall, Because You Left is a thrilling and suspenseful episode that sets the stage for a season full of surprises and twists. It is clear that the characters are in for a wild ride, and viewers will be on the edge of their seats as they try to piece together the mysteries of the island and its connection to time.
