Sun creates a garden in the jungle, where she grows a variety of different herbs and fruit plants. She is helped by Kate, who then figures out that she speaks English. She begs Kate not to tell anyone else. Later, Sun attempts to bathe in the sea, but is quickly escorted away by Jin, prompting Michael to intervene. Sun slaps him for intervening, but apologizes to him later. Jin suspects something between the two and grows wary. That night, after the raft burns down, Sun discovers Jin in the caves with burn marks on his hands. She asks Jin if he caused the fire, to which he grows angry. When he is accused and beaten by Michael, Sun is forced to reveal her long-hidden bilingualism in front of Jin, and begs Michael to stop. Later, Jin leaves Sun, refusing to speak to her. When Boone is brought to the caves in critical condition, Sun helps Jack in the ensuing operation, retrieving a sea urchin in order for Jack to make a blood transfusion. Despite their efforts, Boone dies later that night.
