Carole: I believe I'm the reason he was in Australia when he died.
Jack: I'm sorry. I don't understand. Why would he have come to see you?
Carole: Oh, he... he didn't come to see me. I was still in the hospital. I never saw him. He came to see his daughter. My daughter, Mr. Shephard.
Jack: My father didn't have a daughter--
Carole: Yes. He did. If you don't believe me, check his phone records. Would you like to know the--the strangest thing about all this, Mr. Shephard? My daughter was on your plane, too. She was on flight 8-1-5. You were in the air for six hours, probably just a few rows from her and you never even knew she was your sister. She was one of the ones who died when your plane hit the water. Her name was... Claire. I didn't mean to burden you with this, but... you needed to know. I'm... sorry for your loss.
