Supervising producer Javier Grillo-Marxuach, who wrote "House of the Rising Sun", found it difficult to write the Jin-Sun storyline, as he did not speak Korean and had to get into a "cultural headspace" for which he had no personal reference [REF].
Grillo-Marxuach stressed the importance of the episode due to the discovery of the caves, which prompts the survivors to become "full-time dwellers of the island."[REF]
