Plot
2004
Following the events of the season premiere, "
LA X",
Jack Shephard arrives late to pick up his son, David (
Dylan Minnette), from school. Returning home, Jack is asked by his mother (
Veronica Hamel) to visit her house and help her find his
father's will, leaving David alone. While there, they discuss David, who was quite upset when his grandfather died, but never showed it to Jack. She suggests that perhaps David is "terrified" of Jack, just as Jack was afraid of his father as a child. Finally, they find the will, but Jack's mother is surprised to see that
Claire Littleton (
Emilie de Ravin) is included in it. Jack returns home to find that David has snuck out. Jack goes to David's mother's house, where he learns that David is at an important piano recital. Jack goes to the school, where David performs a stunning arrangement on the piano. Jack also runs into Dogen (
Hiroyuki Sanada), another parent at the event. He says his son, David has got a gift. Afterwards, David, tells Jack that he didn't want Jack to know that he continued to play piano because he doesn't want to disappoint his father, should he fail. Jack explains his complicated relationship with his father and reassures his son that he can never be a disappointment to him.
2007
Following the events of the episode, "
What Kate Does", at the
Others' temple,
Hugo "Hurley" Reyes (
Jorge Garcia) is approached by the deceased
Jacob (
Mark Pellegrino), who sends Hurley on a mission: Someone is coming to the island; he and Jack must travel to a lighthouse, in order to aid their arrival. Hurley has free rein to complete the mission because he is a
candidate and even Dogen cannot stop him. Hurley uses the phrase "
you have what it takes" to recruit Jack. Along the way, Jack and Hurley encounter
Kate Austen (
Evangeline Lilly), who tells them that she will neither return to the temple nor go with them, but continue her search for Claire. Jack and Hurley eventually pass through the caves, encountering Jack's father's coffin and the
"Adam & Eve" skeletons. Hurley speculates that due to time travel, the skeletons could be someone they know in the present.
Jack and Hurley arrive at the lighthouse, at the top of which is a large dial and a series of mirrors lined up. Each notch on the dial has a name listed next to it, corresponding to the names and numbers seen in Jacob's cave in "The Substitute". Hurley begins to move the dial to 108 degrees (the sum of the Numbers) as instructed by Jacob, but Jack catches a glimpse of a house in the mirror and stops him. Noticing his last name on the 23 degree mark, Jack aligns the dial to match. Jack's childhood home is reflected in the mirrors and Jack becomes extremely upset. He angrily interrogates Hurley, who is unable to answer any of his questions, leading Jack to destroy the mirrors. Outside, Jacob reappears to Hurley, congratulating him on bringing Jack to the lighthouse. Hurley realizes that Jacob did not want them to send a signal from the lighthouse, but instead needed Jack to see into the mirror and realize that he is important to the island.
At the same time,
Jin-Soo Kwon (
Daniel Dae Kim) is rescued by Claire from her trap, taking him and an injured Other, Justin, to her hideout. She treats Jin's leg injury and then threatens to kill Justin unless he tells her the location of her son Aaron. Justin helplessly says that he has no idea where Aaron is and the Others never kidnapped him. Claire believes that the Others have her baby because both her father and "her friend" told her so. Jin informs her that Kate has been raising Aaron off the island. Claire murders Justin, regardless, claiming he would do the same given the chance. Jin then claims that he was lying about Aaron earlier, leading Claire to say she would have killed Kate if it were true. Later, Claire's "friend", who turns out to be the Man in Black (
Terry O'Quinn), shows up as Jin and Claire discuss how to return to the temple.
