Plot summary
A woman blackmails Sun over Jin being the son of a prostitute. His father confirms this when Sun goes to visit him, and Woo-Jung gives Sun the money on the condition that Jin begins working as his enforcer. Realizing that the woman is Jin's mother, Sun warns her to never return. In the present, Juliet takes Sun to the Staff to test her baby's date of conception and see if she is in danger. She agrees and is informed that the baby is Jin's instead of Lee's, leaving her overjoyed.
Juliet secretly leaves a tape behind informing Ben of what transpired and that she will reluctantly take "samples" from other women. Mikhail, who has survived the fence, comes across Desmond's group and the heavily injured parachutist, Naomi Dorrit. He treats her wound and they reluctantly let him go. When she wakes, she informs Hurley that Flight 815's wreckage was already found and all of the passengers were confirmed dead.
