 Desmond tells Charlie about his latest premonition : Charlie 's girlfriend Claire Littleton ( Emilie de Ravin ) and her baby Aaron will escape the island via helicopter if Charlie flips a switch in a Dharma Initiative station and drowns . Sayid tells Jack that he may be able to communicate with the freighter roughly 130 kilometres offshore . He can use the satellite phone of Naomi Dorrit ( Marsha Thomason ) , a woman working with those on the boat , once he goes to the radio tower to disable Rousseau 's distress signal . Juliet Burke ( Elizabeth Mitchell ) informs Sayid that this will not work because the underwater " Looking Glass " is blocking outgoing transmissions . Sayid realizes that a cable he found seventy days before connects to this station and that they will need someone to go on a probable suicide mission there , and Charlie volunteers .
