Sun becomes one of the Oceanic Six, one of the six publicly known survivors of Flight 815. As part of the cover-up story, Sun reveals that Jin never made it off the plane after it crashed. Shortly after arriving home in Korea, Sun buys a majority share of her father's company with part of the Oceanic settlement that she received, and tells him that she holds him as one of two people responsible for Jin's death (the second person being Ben, as revealed in Season 5.) Several months later, Sun goes into labor and gives birth to a healthy baby girl. She names her daughter Ji Yeon, due to Jin's request on the island. She is later visited by Hurley, and the two visit Jin's grave, where Sun says that she misses him and was calling for him during labor, knowing that he wasn't there.
