Plot summary
As Jack learns that Claire is named in Christian's will, he struggles to maintain a relationship with his distant son David. He learns about his audition for a music school and hurries to see it, reconciling with him as Dogen, the parent of another student, praises David's ability. On the island, Jacob instructs Hurley to go with Jack to a lighthouse. At the top, they find a dial with "candidate" names etched into it, and when Jack turns it to his name, an image of his childhood home appears. Hurley realizes that Jacob asked him to take Jack so he could gain a sense of purpose. Claire, having been manipulated by the Man in Black into thinking the Others have Aaron, takes Jin and an Other to her hut. When Jin explains that Kate has Aaron, Claire kills the Other and threatens to do the same to Kate.
