Jin rushes to the caves but Jack is occupied with the blood transfusion. Jack tells Jin to take Charlie to Kate and Claire, and gives Charlie instructions for Kate on delivering the baby. As Jack begins to turn pale Sun stops the transfusion because the blood is pooling in Boone's dead right leg.

Production
In the original outline of the eleventh episode, Locke was to be accompanied by two guest characters to search for Claire and discover the Hatch. In the final product, Boone accompanied Locke, a choice that would lead to Boone's death. While the executive producers have stated that Somerhalder took the news of his character's death professionally, Somerhalder has said that he found it "pretty devastating." Boone's death is notable as the first death of a major character on the series. According to executive producersDamon Lindelof and Carlton Cuse, Boone's death made sense from a story perspective to fuel the rivalry between Jack and Locke and lead to the events in the season finale." Variety called him "hot-headed." Following Somerhalder's departure from the show, ABC signed him to another one-year contract. Somerhalder stated that being a part of Lost was "the greatest experience" of "the greatest year of his life".
Reception
The American viewers for this episode were 17.12 million. IGN ranked Boone's death as #4 in their list of the top tenLost deaths.
