We go even farther back in John Locke’s story to find him working at a Walmart type store. Could be Target too, I’m not playing favorites. He is talking to a boy about the game Mouse Trap that Locke is setting up. Meanwhile, an older woman with red hair is watching him. Locke later sees her in the parking lot watching him. Locke confronts the woman and she admits to him that she is his mother. She tells him her name is Emily Locke and the two go have lunch where she tells John he was immaculately conceived.
On the island Sawyer is suffering from severe headaches. Kate asks Jack if he can help to which Jack answers with one of the best Jack lines of the entire show: “I’ll get nothing out of helping Sawyer other than a snappy one liner and if I’m lucky a new nickname.”. Eventually Kate convinces Jack to help Sawyer. During an examination Jack asks Sawyer a few uncomfortable questions including if Sawyer has ever had sex with a prostitute or had an STD. Sawyer admits to having sex with a prostitute but says nothing about the STD. Jack takes his silence as a “Yes” and asks when his last outbreak was. Sawyer looks at Kate seeming to be a little embarrassed, but Kate seems entertained by the interaction and slyly smiles at Jack. Jack later tells Sawyer he needs glasses which Sayid manages to make a pair of glasses for him by melting the halves from two different pairs together to hopefully help with the headaches.
Locke has hired a private detective to do some research to get info on his mother and father. The P.I. tells Locke that his mother has been hospitalized a few times for schizophrenia. Locke then asks about his father. The P.I. is a little reluctant to give him the information and warns Locke that sometimes these things don’t work out how the children want them to. He eventually gives Locke the information which includes his father address and the name of his father, Anthony Cooper. Cooper welcomes Locke into his home and says he didn’t know anything about John because Emily told him she wasn’t going to have the baby. A year later she came to him for money and that was the first he learned he had a child. The two quickly bond while going on hunting trips together. One day John arrives early and sees his father hooked up to a dialysis machine. Cooper tells John his kidneys are failing, and he needs a transplant, but he is way far down the donor list. Locke tells him he will give Cooper one of his kidneys. The two are then both shown in the hospital getting ready for the transplant. The two hold hands as John tells his father that this was meant to happen.
After John has the nightmare, he tells Boone about it and says they must find the plane. Boone is a little hesitant until Locke asks Boone who Theresa is. Taken aback, Boone asks Locke how he knows about Theresa. Before he can explain he falls after loosing feeling in his legs. Locke sees a rosary hanging from a tree and tells Boone that it came from a dead body Locke knocks out of the canopy of trees just above them. The two check out the corpse and see it is wearing clothes that look like something a priest would wear. They also find Nigerian money in the pocket. Boone wonders why a Nigerian priest would be crashed on the island. After John finds a gun on the body it seems the man is not a priest at all. As the two continue Locke falls as he looses more feeling in his legs. Boone wants to get Jack, but Locke says no and then tells Boone that he was in a wheelchair for four years before the crash, but the island has heeled him. Locke says the island is trying to take the gift back from him but the two must find the place where the plane crashed as that will help them open the hatch.
The two continue and Boone tells Locke that Theresa was his nanny when he was a young boy. One day Theresa fell down the stairs and broke her neck. John, who can no longer walk at all looks up and laughs when he sees the plane they are looking for sitting on the edge of a small cliff. Locke tells Boone he has to go investigate the plane. Boone climbs up the cliff using vines and inside the plane finds Virgin Mary statues all filled with heroin. He throws one statue down telling Locke the plane meant nothing. Boone then sees a radio on the plane and turns it on. Boone contacts someone else on the radio and tells them he is a survivor of flight 815. The voice on the radio tells Boone that they are the survivors of flight 815. The plane suddenly drops off the cliff and slams down to the ground. Still barely able to walk, Locke pulls Boone out of the plane. Locke walks back to the caves with Boone lying across his shoulders.
Locke awakens after the transplant and finds that Cooper has checked himself out of the hospital. Emily walks into the room and tells John that Cooper forced her to help con John into donating a kidney. John leaves the hospital emotionally crushed and goes to Cooper’s house where he is denied entry by a security guard. Locke drives away from the house screaming in emotional agony after having been betrayed so ruthlessly by his father.
Locke makes his way back to the caves and tells Jack that Boone fell from a cliff while hunting. Before Jack gets all the explanation he wants from Locke, he discovers John has already left. Returning to the hatch, and like his anguish over Cooper’s betrayal, Locke screams as he collapses at the hatch now feeling betrayed by the island. He bangs onto the hatch and screams that he has done everything the island has asked him to do. Suddenly a light shines out from inside the hatch. Locke looks at the hatch with a look of amazement on his face.
