Jack and Kate return to the beach and Jack starts talking to people about moving to the caves. The castaways argue whether to stay on the beach where a rescue party could see them (and keep the signal fire burning), or move to the caves, where there is more shelter and fresh water. The group splits into two camps accordingly: Jack, Locke, Charlie, Hugo "Hurley" Reyes (Jorge Garcia), Jin, Sun, Ethan Rom (William Mapother), Dr. Leslie Arzt (Daniel Roebuck), Doug, and Sullivan (Scott Paulin) move to the caves while Kate, Sawyer, Sayid, Claire Littleton (Emilie de Ravin), Michael Dawson (Harold Perrineau), Walt, Vincent (Madison), Shannon Rutherford (Maggie Grace), Boone Carlyle (Ian Somerhalder), Rose Nadler (L. Scott Caldwell), Scott Jackson (Christian Bowman), and Steve Jenkins (Dustin Watchman) remain on the beach.
