Suddenly, Rousseau spots an endless ring of cement pylons that disappear into the jungle as far as the eye can see. It's the Others' security perimeter. Kate starts to walk through, but Sayid stops her. He says the sensors would be triggered. Mikhail claims it hasn't worked for years. Locke grabs Mikhail and shoves him between two of the pylons. Instantly an odd, electronic sound rings out. Abruptly, Mikhail starts twitching. His eyes roll back in his head, blood trickles out of his ear and saliva foams at the corners of his mouth. He falls over and spasm violently. Then he goes still. Everyone is stunned.
Jin and Sun help Claire try to capture one of the birds when BAM! BAM! BAM! Gun shots ring out and scare the birds away. It was Desmond hunting for boar. Claire is incensed and immediately suspicious. She knows it somehow involves Charlie. She confronts Charlie about his and Desmond's behavior. Charlie struggles whether to tell Claire about Desmond's prediction. Instead he says her plan is a crazy scheme and he doesn't want to advocate false hope. Claire is angry and hurt. She thought she could count on him. She now realizes she's on her own and tells Charlie to leave.
Back in Sydney, Claire discovers her mother has a new visitor it's Dr. Christian Shephard, Jack's dad. Claire doesn't know him, and is about to ask who he is when Lindsey walks in. Lindsey and Christian immediately start arguing. She doesn't want him there and tells him to go. Christian says Claire deserves to know the truth, but Lindsey won't hear of it. Claire shouts for them to stop arguing. She realizes he's the one paying the hospital bills. Reluctantly, Christian admits that he is her father.
Over coffee, he explains that he had a fling with her mom. She got pregnant and had Claire. Christian visited a couple times when he could, brought her toys and sang to her. However, Aunt Lindsey and Claire's mother didn't like that he had another family and told him to stay away. He's here now to help Claire. He says her mother's alive but not living. He suggests thinking about taking her off life support and not keeping her alive for the wrong reasons. Claire gets angry. She tells him paying the bill doesn't make him noble. She has hope her mom can get better.
