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."[12] Referring to the episode's Jin-Sun and Locke-Charlie storylines, Grillo-Marxuach felt that the island was about being "forced to confront your inner demons [and] work out things" never addressed before.[12] Charlie's fear of bees is based on Grillo-Marxuach's life experience.
