[edit] Plot

[edit] Flashbacks

In flashbacks, we see Sun in a park. A middle-aged woman sitting next to her points out Sun's wedding photograph with Jin-Soo Kwon (Daniel Dae Kim) in the newspaper and inquires if that's her. Sun affirms that it is. The woman suggests that it would be embarrassing if the world were to find out that a daughter from the wealthy Paik family had married a man with a shameful past. Sun says that she knows Jin is the son of a fisherman and doesn't care. The woman retorts that he is also the son of a prostitute. The woman then demands a hundred thousand dollars in three days or else she will expose Jin's past.

Later, Sun asks her husband about his family. He tells her that his mother died when he was a child, then gives conflicting stories on when his father died. When she pushes for more information, he grows angry and asks her to drop the issue. Sun visits Jin's father without his knowledge, who confirms the woman's story. He never told Jin his mother was a prostitute and is still alive, and pleads with Sun not to tell his son the truth. He also mentions that he raised Jin alone and is not even sure he is his biological father.

Sun then visits her father (Byron Chung) and asks for the money. When he demands a reason, she tells him that she has never pried into his affairs, which are clearly illegal, and would like the same respect. However, she admits that the money will prevent great shame coming to someone she loves. Mr. Paik realizes she means Jin, and tells her that he will bear the debt by working for him directly, instead of as a floor manager.

Jin discovers the money in Sun's purse. She concedes she got it from her father, but claims it was just for furniture and their honeymoon. Jin says he doesn't want to be any further in her father's debt, and asks her to return it. Sun agrees, then goes directly to the park, where the woman is waiting. She gives her the money, then reveals that she knows the woman's identity: she is Jin's biological mother. The blackmailer callously shrugs this off and Sun threatens to have her father kill the woman if she reveals her existence to Jin.

[edit] Sun's pregnancy

On the island, Jack Shephard (Matthew Fox) inquires about Sun's pregnancy in a manner that arouses her suspicions. Sun asks Kate Austen (Evangeline Lilly) about Jack's loyalty. Kate suggests she talk to Juliet Burke (Elizabeth Mitchell), who reveals that pregnant women die on the island. That night, Juliet sneaks into Sun's tent and offers to help her, but only if she comes with her, alone. The pair leave for the Staff, to get an ultrasound image, so Juliet can calculate the date of conception. Juliet reveals that women who conceived off the island can survive; those that conceive on the island can't. Sun explains how her husband was sterile before coming to the island, and how she had an affair with Jae Lee before the crash. Either way, it's bad news: either she's going to die, or the baby is not her husband's. Juliet performs the ultrasound, and confirms that the conception took place after the crash. Sun sincerely thanks Juliet for the news, reassuring her that she delivered good news. Juliet asks Sun if she'll be okay waiting outside as Juliet "covers their tracks" in the medical station, then she enters the Staff alone to surreptitiously leave a message for Ben Linus (Michael Emerson) on a tape recorder, explaining her findings with Sun, and promising to get a sample from Austen (Kate). She then stops the tape and whispers, "I hate you."

[edit] The Parachutist

Meanwhile, Desmond Hume (Henry Ian Cusick), Hugo "Hurley" Reyes (Jorge Garcia), Jin and Charlie Pace (Dominic Monaghan) are arguing how to care for the parachutist, Naomi Dorrit (Marsha Thomason) when Hurley accidentally shoots off a flare. Mikhail Bakunin (Andrew Divoff), thought to have died in an earlier episode, appears shortly thereafter. He attempts to flee, and Jin pursues him, subduing Mikhail with a flying reverse roundhouse kick. The other three question him, revealing that Sayid Jarrah (Naveen Andrews), Kate and Jack told them how he'd been supposedly killed by the sonic fence. Mikhail says he was a field medic and offers to help save the parachutist's life, if they promise to let him go. The parachutist fades in and out of consciousness, at one point asking in Mandarin Chinese, what happened. She also tells them, in Portuguese that she is not alone. Mikhail seems to understand this but tells Desmond that she merely said "Thank you." He keeps his word and they keep theirs, but Mikhail attempts to steal the satellite phone, only to be stopped again by Jin. After a brief argument, they allow Mikhail to leave without the phone. Later, Charlie and Desmond argue over whether they should have allowed Mikhail to go. Charlie says the Others are too dangerous, and Desmond points out that "By my count, you killed more of them than they've killed of you." Charlie can only respond, "They started it."

The parachutist regains consciousness while Hurley is watching over her. She asks him who he is. he tells her he is Hugo Reyes, from Oceanic Flight 815. She replies, "That's not possible" because "They found the plane. There were no survivors. They were all dead."
