Shannon sees Walt again, once more dripping with water, and he speaks backwards. Sayid thinks she was dreaming. Shannon tries to get Vincent to lead her to Walt, but instead he takes her to Boone’s grave.
Claire mentions the possibility that Charlie is a religious freak, and when Locke says he doubts that, Claire tells him that Charlie has a statue of the Virgin Mary.
Michael asks why they have to keep quiet, and we learn that 12 of the tailies were taken by the others. Later, as they are traveling, Cindy goes missing, then we hear the whispers.
This episode has important backstory about Shannon. We judged her, seeing her manipulate Boone to get money later in life, but now we see how she was deprived of a rare internship opportunity at the Martha Graham Institute by her stepmother. On the island, Sayid says he believes in her, then they hear the whispers, and Walt tells them to shush, but Shannon runs after him. We have our assumptions about her challenged just in time to see her die, shot by Ana-Lucia. And so the story, even as it is making us afraid, it is warning us about what fear makes us become.
