Season 1, Episode 2:
Pilot, part 2Jack, Kate and Charlie walk back to the beach with the cockpit's transceiver, which isn't working. When asked, Charlie claims that he was vomiting in the cockpit's bathroom when Kate and Jack couldn't find him earlier.
FLASHBACK! Moments before Oceanic 815 crashes, Charlie runs to the bathroom to hide his stash of heroin by flushing it down the toilet while air hostesses bang on the door. Before he can flush the toilet, 815 starts going down, and Charlie buckles himself into an empty seat.
On the beach, Shannon refuses to help the other survivors sort through the luggage. Claire admits that she hasn't felt the baby move since the crash. Michael searches for Walt and meets Sun and her controlling husband Jin, neither of whom can speak English. Walt finds a pair of handcuffs in the jungle. Sawyer attacks Sayid, accusing him of being a terrorist and crashing the plane, but Jack returns in time to separate them. Sayid volunteers to try and fix the transceiver, later telling Hurley that he was a communications technician in the Republican Guard during the Gulf War. Kate strips off in the ocean. Once the transceiver is working, Sayid proposes an expedition to higher ground where he can get a signal and call for help. Kate volunteers to come along, but Jack has to stay behind because one of the survivors has a bad shrapnel wound. Jin is able to catch some sea urchins for food, but no one will eat them. Jack sets Hurley and other to work on scouring the luggage for medicine, particularly antibiotics. Boone tries to help the other survivors and berates Shannon for her laziness; to prove him wrong, she volunteers to join the group heading to high ground, and Boone goes too so that he can keep her out of trouble. After reading a letter that seems to upset him, Sawyer joins the group as well. Michael learns that Vincent, his son's pet labrador, is alive and running around the jungle. Walt approaches Locke, who is setting up a backgammon game on the beach, and tells him about how his mother died earlier that month.
Locke: Backgammon is the oldest game in the world. Archeologists found sets when they excavated the ruins of ancient Mesopotamia. Five thousand years old. That's older than Jesus Christ.
Walt: Did they have dice and stuff?
Locke: [nods] But theirs weren't made of plastic. Their dice were made of bones.
Locke: Two players. Two sides. One is light. One is dark. [pause] Walt, do you want to know a secret?Jin offers Claire one of the urchin. Once she eats it, she feels her baby kicking again and impulsively refers to it as a "he". Jack and Hurley remove the shrapnel from the wounded survivor, though Hurley faints at the sight of so much blood. Kate and Sayid's group are hiking through the jungle when something large and loud charges at them; while the others run, Sawyer pulls a handgun and shoots the creature, which they realise is actually a polar bear (though Charlie claims it's much smaller than whatever killed the pilot). While they try to figure out why a polar bear would be on a tropical island, Kate questions Sawyer how he got a gun. He claims he got it from the body of a dead US Air Marshal, and Sayid theorises that Sawyer was the prisoner that the Marshal was transporting.
Sawyer: I saw a guy lying there with an ankle holster, so I took the gun. I thought it might come in handy. Guess what? I just shot a bear!Kate grabs the handgun and Sayid tells her how to take out the bullets.
FLASHBACK! It's revealed that Jack's patient is the US Marshal and Kate was his prisoner. When the plane starts to crash, the Marshal is knocked out and Kate is able to strap an oxygen mask to his face. Moments later, the tail section of the plane is ripped away.
On the beach, the Marshal wakes up and asks "Where is she?" The hikers reach high ground and get a weak signal on the tranciever. Sayid tries to transmit but can't because another signal coming from nearby is blocking them out. They tune in to a looped transmission in French, which Shannon translates.
Shannon: I'm alone now, on the island alone. Please, someone come. The others, they're ... they're dead. It killed them. It killed them all.Each loop finishes which a running count of the number of times the message has been replayed. Sayid does the math and realises that it's been playing on a loop for 16 years.
Charlie: Guys... where are we?
