Juliet: Why are you scared?
Ben: I'm not scared.
Juliet: Why are you scared, Ben? You said no one on this island ever had cancer. You told me that.
Ben: I know what I told you, Juliet.
Juliet: You told me you could fix it. You said that. You said that you cured my sister! You lied to me!
Ben: No, I did not lie to you!
Juliet: If you can cure cancer, Ben, then why do you have it?
Ben: I don't know.
Juliet: I wanna talk to her. I wanna talk to Rachel. I wanna talk to her now!
Ben: It's not gonna happen, Juliet. But I can promise you that Rachel is fine.
Juliet: You never cured her!
Ben: I did!
Juliet: No, you're a liar!
Ben: Don't you let--
Juliet: You lied to me!
Ben: I told you the truth! I gave you my word.
Juliet: (crying) I know. I wanna go home. I wanna go home, Ben. Please. Can't you please just let me go home?
Ben: No.
