The episode was written by Drew Goddard and Jeff Pinkner and directed by Jack Bender.
He goes to a government building and finds out he needs to give unwanted information from him in order to keep getting paid his disability insurance.
As Locke lies in a hospital bed, the two detectives inform him that his father has fled to Mexico and has now disappeared.
Outside the Others' compound, Locke, Sayid Jarrah (Naveen Andrews), Kate Austen (Evangeline Lilly) and Danielle Rousseau (Mira Furlan) are shocked to see Jack Shephard (Matthew Fox) interacting familiarly with the Others, and Kate insists that the Others have done something to him.
They are interrupted — first by Ben's teenage daughter Alex (Tania Raymonde), whom Locke grabs and hides with in the closet, and then by Tom (M. C. Gainey) and an unseen Richard Alpert (Nestor Carbonell), who tells Ben that they captured Kate and Sayid trying to rescue Jack.
Ben tells Tom to separate the two and interrogate them, and instructs Richard to bring him "the man from Tallahassee."
After the two leave, Locke asks Alex to get Sayid's pack, and Ben concludes he is doing so to destroy the Others' submarine.
Ben reveals that he wanted to find a way to keep Jack from leaving the island, but did not know how to; Locke had solved this problem.
During the last flashback, Anthony Cooper serves a bottle of MacCutcheon 60 whiskey to Locke, the same type used by Charles Widmore (Penelope's father) and Desmond, Charlie and Hurley in "Flashes Before Your Eyes", and Sayid in "He's Our You."
The submarine was mostly a prop made of painted styrofoam over a steel structure, but its interior was shot inside the SS-287 at the USS Arizona Memorial.
