Plot Overview

The Island

  • Working alone in her garden, Sun hears someone approaching and is relieved when it turns out to be Jack. He questions her about her pregnancy but, when asked why he wants to know so much, tells her he just wanted to check up on her since he came back. Sun returns to the beach camp and helps out Kate with her shelter. She asks Kate what she thinks happened to Jack while he was with the Others as he seems different. She tells Kate that Jack was asking about her pregnancy and thinks the Others may want her baby. Kate assures Sun that Jack isn't working with the Others, and tells her that Juliet was the Others' fertility doctor studying pregnant women on the island. The Others wanted Claire's baby for research. Sun confronts Juliet, demanding to know what happens to pregnant women on the island, and learns that they all died.

    That night, Juliet sneaks into Sun's shelter and offers to help Sun and Sun's baby if she comes with her alone. Juliet leads Sun through the jungle to The Staff, telling her it's a medical station with an ultrasound machine. Using the ultrasound machine, she can determine the date of conception for Sun's baby: if it was conceived off the island they'll probably be okay, but if it was conceived on the island then there will be a problem. The two arrive at The Staff and descend inside the station. Questioned as to her motives, Juliet tells Sun that she's helping her because she used to tell women they were pregnant and she could see on their faces that it was the best news they ever got but, since arriving on the island three years ago, she's lost nine patients. She's helping Sun because she wants to give good news again. In response to Juliet's sincerity, Sun reveals to her that she slept with another man before coming to the island when she was having marital problems with Jin. Juliet leads Sun into The Staff's locker room, pulling a hidden lever inside one of the lockers which unlocks a vault door recessed into one of the walls. Inside the hidden room, Sun sees a bunch of nursery items and other objects, and is told this place is where the Others brought the women to die.

    As Juliet preps for the ultrasound, Sun tells her that the baby couldn't be Jin's because a fertility doctor told them Jin was infertile. Juliet tells her that the average male sperm count is between 60-80 million, yet it's five times that when on the island. Using the ultrasound machine, Juliet shows Sun her baby and informs her that it's very strong and very healthy. But, after making some calculations, Juliet tells Sun that the baby was conceived on the island and is Jin's. She promises to do everything she can to help Sun.

    With the sun already risen, Sun and Juliet exit The Staff. Juliet tells her that most of the other pregnant women made it into the middle of their second trimester and no one made it to their third trimester, so Sun has about two months left. Despite that, Sun tells Juliet that she gave her good news. Leaving Sun above ground, Juliet descends back inside The Staff to "cover their tracks". Heading inside the hidden room, Juliet retrieves a cassette recorder from a locker and leaves a message for Ben, informing him that Sun is pregnant from her formerly sterile husband and that the baby was conceived on the island. She is still working on getting samples from the other women of the survivor's camp and will report back when she has more. With the recording stopped, Juliet tells herself that she hates Ben.

  • Desmond, Charlie, Jin and Hurley crowd around the woman who parachuted from the crashed helicopter. Even though the woman knew Desmond's name, Desmond has never seen her before in his life. The woman mumbles something and Hurley realizes she speaking Spanish; she says she's dying. The group soon discover a branch lodged in the side of her torso. Charlie and Jin suggest they bring the woman to Jack, but Desmond doesn't want to risk moving her and tells them he'll run to get Jack. Charlie reminds him that the Others, people who want to kill them, are somewhere out there on the island. Desmond tells him that no one knows where they are, but Hurley accidentally sets off a signal flare giving away their location.

    Desmond and Charlie continue to argue over how to best get help for the woman, but are interrupted when Mikhail appears out of the jungle. Mikhail and the group exchange quizzical looks before Mikhail takes off running away from them with Jin, Desmond and Charlie in hot pursuit. Jin manages to catch up to Mikhail and, after a brief fight, subdues Mikhail until Desmond and Charlie can arrive. Mikhail is brought back and Charlie realizes that the man is the one who shot Sayid and lived in The Flame until Locke blew it up, but Hurley points out that Mikhail was supposed to have been killed by the barracks' security fence. Desmond threatens to fire a flare into Mikhail chest at point-blank range, but Mikhail reminds him that he already died once this week. The woman mumbles something and Mikhail tells the group it's Italian, that she says she's dying and needs help. He tells the group that he was a Soviet Army field medic and could help. Looking over the woman's wound, Mikhail tells them the branch punctured her lung and she'll die if it isn't ventilated. He offers to fix her in exchange for letting him go.

    Mikhail works on the woman's injuries well into the night. He questions the group as to what else she had on her and Hurley accidentally tells him about the satellite phone. With Desmond holding the woman down, Mikhail plunges a syringe through her chest and into her lung, and then pulls the branch out of her torso. Mikhail has Desmond tape gauze over the wound, cautioning him to keep the cavity hollow so it would have room to breathe. Delirious, the woman mumbles something else and Mikhail claims it was a thank you. He tells the group that the woman will live and she should be better in a day. Charlie reminds him that her lung was punctured, but Mikhail tells him that wounds are different on the island. Living up to his end of the bargain, Desmond lets Mikhail go, but Jin discovers the satellite phone is missing and gives chase. Jin takes the satellite phone back from Mikhail, and Mikhail smugly asks them how they could respect him if he didn't try. Charlie argues against letting Mikhail go, but Desmond lets him go again.

    By morning the group has constructed a stretcher for the woman. Charlie continues to argue for Mikhail's death, but Desmond tells him that they've killed more of the Others than they have of the Oceanic survivors. A short distance away, Hurley keeps the woman company while playing with the inoperative satellite phone. The woman regains consciousness, demanding to know where she is and who he is. Hurley tells her he is one of the survivors of Oceanic flight 815, but the woman tells him the plane was found and there were no survivors.

The Flashback

  • Flashback: Sun

In Korea, shortly after marrying Jin, Sun talks to him over a cellphone. After finishing her conversation with him, a woman sharing her bench points to a photograph in the newspaper and asks Sun if that is her and her husband. The woman congratulates Sun, telling her she's a very lucky woman, but then asks Sun if her family are the ones who own Paik Automotive. Sun tells her she doesn't have much to do with the family business and, questioned about Jin's parents, tells the woman that they're dead. The woman informs Sun that there would be much shame if it was known Mr. Paik's daughter married the son of a fisherman. Sun tells her she knows and it doesn't matter to her. However, the woman informs Sun that Jin is also the son of a prostitute. She tells Sun that she will return in three days and demands that Sun bring her $100,000 or she will reveal the truth.

Sun is unpacking their belongings at their new apartment when Jin arrives with soup. Looking at her framed pictures, Sun asks Jin if he has any pictures of his family. Jin tells her he didn't have a camera growing up and his father never left any pictures as he was in the army when he died. Sun asks him how that could be possible when she was told his father died when he was sixteen. Upset at her questioning, Jin tells her she must have misunderstood and asks her why she's questioning him. Sun tells him it's nothing and apologizes.

Sun goes to the Namhae fishing village Jin grew up at and approaches his father, Mr. Kwon. Mr. Kwon invites her to his home for some tea and inquires as to how their wedding went. Sun learns that Jin claimed his father was dead to avoid the shame of where he came from, and that Mr. Kwon claimed Jin's mother had died to avoid the shame she would bring upon Jin. Jin's mother had slept with many men and left Jin with Mr. Kwon. He didn't even know if Jin was his baby, but raised him regardless as there was no one to take care of him. He pleads with Sun not to tell Jin that she met him or that his mother is still alive, so that he won't suffer that shame.

Returning home, Sun visits her father at his office at Paik Automotive. She tells him that she needs $100,000 and can't tell him what for. Mr. Paik's delight at seeing his daughter turns to consternation as he refuses to give her anything without an explanation. In response, Sun tells him she has pretended not to know what he does and allowed him to control her, but she would only continue to pretend if he gives her the money with no questions. Angered at being blackmailed by his own daughter, Mr. Paik deduces that Sun is doing it for her new husband, Jin. Mr. Paik takes $100,000 out of his personal safe and places it in an envelope. He warns Sun that if the money is for her husband, then it is he who would bear the debt by no longer being a floor manager. Instead, Jin would work for him personally. Despite the warning, Sun takes the money and leaves.

At their apartment, Jin discovers the envelope of money in Sun's purse. Covering for the true purpose of the money, Sun tells him she got it from her father for furniture and a nice honeymoon. Jin tells her that, although it may take longer, he can provide for her. He asks that she return the money to her father as he doesn't want to be any further in his debt than he already is.

Three days after the woman confronted her, Sun finds the woman at the specified location. Sun gives her the $100,000 and asks her why she didn't tell her she was Jin's mother. The woman defiantly tells Sun that, although she may have given birth to Jin, that does not make her his mother. Angered by the woman, Sun reminds her of how powerful her family is and threatens to have her killed if she gives her reason to.

The Cursed Numbers

  • Charlie says they're an 8 hour walk away from the beach camp.
  • Mr. Kwon's blue fishing marker has 4 and 16 written on it.


  • Continuity Error: In the scene where Sun walks along the dock, the long shot of her walking shows Mr. Kwon's fishing boat with an orange marker on board. In the subsequent close-up shot, the boat has an additional blue marker not present in the previous shot. Mr. Kwon's boat also shifts position while Sun is walking up to it. In the establishing long shot of the dock from shore, Mr. Kwon's boat is tied up on the far side of the dock. The next long shot and subsequent shots have Mr. Kwon's boat tied up on the near side of the dock.
