Season 2, Episode 2: Adrift

The Others have kidnapped Walt and left his dad, Michael, Jin and Sawyer, who was shot in the altercation, for dead adrift at sea. Away from the island in flashbacks, we see Michael's struggles with Walt's mom, Susan, about custody of the precocious boy.

MAJOR PLOT POINTS

At sea, Sawyer saves Michael from the water and performs CPR. But upon coming to, Michael blames Sawyer for his son going missing. He yells at Sawyer to get off his raft, so he obliges and moves to a different piece of debris. Shot in the shoulder, Sawyer digs the bullet out of his own shoulder. He's also figured out that the boat which abducted Walt had a short range, so it had to come from somewhere nearby.

When his piece of the raft breaks up, Sawyer is forced to rejoin Michael. When the raft breaks up, Michael and Sawyer swim for a pontoon and now it's Michael's turn to save Sawyer by shooting a shark before it gets to him. Michael now blames himself for Walt's kidnapping, for taking him on the raft in the first place. As day breaks, Michael and Sawyer drift back to the island where they encounter a bound Jin fleeing "The Others," who are actually the survivors from the tail section.

On the island, Locke rappels down into the hatch by himself and upon reaching the bottom, he enters the underground bunker, which has Dharma Initiative insignia throughout. He runs into Desmond, who asks, "Are you him?" Of course, Desmond figures out that he's not his replacement and takes Locke hostage. Kate is already bound, but when Jack shows up Dez locks up Kate in the food room (with a knife from Locke hidden in her pants). She manages to free herself and escapes into the ventilation system.

Locke enters the numbers and resets the countdown in the hatch to 108 minutes. Jack think it is pointless and protests Locke's willingness to do as Desmond says. Not messing around, Desmond shoots a warning shot at a vent and nearly drills Kate in the head.

During the flashback, Michael visits a hack lawyer in a last-ditch effort to keep his parental rights to Walt. Susan acknowledges that Michael's likely to win his battle and prevent her from taking him to Italy, but she convinces him that it's best for Walt to drop the court battle.
