On the Island
Miles, Charlotte, Daniel and two survivors of the fire arrow attack are traveling to the creek to meet up with the remaining survivors. When they get there they find no one. The two survivors wander slightly away just as Miles notices trip wires connected to explosives. He shouts a warning, but not before the claymore mines are triggered, killing the two redshirts and dazing the remaining three. Before they can recover, a group of people dressed in Army fatigues emerges from the jungle armed with bows and guns and takes them prisoner. A blond woman, Ellie, states that there were twenty in the group at the beach but only five at the creek. She asks them where the rest of their group is. Miles replies that perhaps the rest of his people were blown up by some more of the Other's land-mines. Ellie says that they did not place the mines, and blamed Miles's group for them (mistaking the group for U.S. military). Ellie asks who is in charge, Miles points to Daniel. The woman again asks Daniel where the rest of his people are and Daniel tells Ellie that he does not know. Ellie and her group then take the three to their camp.
Meanwhile, Locke, Sawyer, and Juliet debate what to do with the two assailants they have captured. Locke identifies the gun that Jones' group was carrying as an M1 Garand that looks new, despite dating from the 1940s or 1950s. Sawyer notices Locke's leg and asks him who shot him, but just before John can answer, Juliet reminds them both that there are more important issues to decide. When the assailants speak to each other in a foreign language, Juliet reveals that she understands Latin, the language they were speaking. Based on their knowledge of Latin, Juliet identifies them as Others: all Others must speak Latin because it is the "enlightened language". Upon learning that their captives are Others, Locke decides to have them take him to their camp. Juliet convinces Cunningham to take them there, but before anything can happen Jones breaks his companion's neck and flees into the jungle. Locke refuses to shoot the escaping man, explaining to Sawyer that the prisoner is "one of my people."
As Charlotte, Miles, and Faraday are taken to the Others' camp, Daniel notices that one of his captors is wearing bandages that he believes cover burns from radiation exposure. Miles begins to behave erratically and tells Daniel that they are walking over top of a fresh grave that is less than a month old. He says that the grave contains the bodies of four U.S. soldiers, three of whom were shot and a fourth who died from radiation exposure. Daniel asks if Miles was able to ascertain what year the soldiers might have said it was, but he doesn't get an answer as they have arrived at the Others' camp: a set of military tents on what appears to be the Mesa. There they are introduced to Richard Alpert, who appears to be, as usual, the same age. The Others believe them to be members of the United States military who have come for "the bomb." Faraday decides to play along with their misconception, and says that they are scientists attached to the American military. Upon noticing radiation burns on one of the Others, he concludes that the bomb is a hydrogen bomb and that its casing is cracked. He offers to deactivate the bomb but Richard wonders if they are not here for a suicide mission, detonating the bomb and destroying the Island with it. Daniel convinces Richard that he will not detonate it by admitting that he loves Charlotte and would not want any harm to come to her. Richard details Ellie to take Faraday to the bomb. Meanwhile, Jones, fresh from his escape from Locke, arrives in camp confident that he was not followed as it would be impossible for "an old man" to track him.
As Faraday is being taken to inspect the bomb, Locke, Sawyer, and Juliet arrive on the outskirts of a camp. When asked how she knew Richard would be among the group, Juliet responds because "Richard has always been here." Locke then asks Juliet just how old Richard is, to which she replies simply, "old." Seeing Faraday being marched towards the woods at gunpoint, Sawyer misinterprets this as an execution and determines to rescue him. However, Locke is determined to head into camp and meet Richard. Locke states that he will give Juliet and Sawyer a ten minute head start to rescue Faraday and then proceeds into camp. Striding into camp and demanding to see Richard, Locke causes a commotion, particularly angering the man whom he had kept prisoner. Locke hopes to continue where he left off with Richard in his conversation, but Richard does not recognize him or know his name. As Jones holds a gun up to Locke and the camp turns hostile, Locke declares that he was sent by Jacob. Stunned, Richard tells the young man to lower his gun but when he refuses Richard angrily aims the man's gun away from Locke, snapping, "I said, 'Put it down', Widmore." Locke instantly identifies the former prisoner as a young Charles Widmore.
Daniel and Ellie inspect the bomb, which is named Jughead. Upon seeing some sort of accretion (expansion or swelling) on the side of the bomb, Faraday recoils in horror and confirms to Ellie that the casing of the bomb is cracked. He tells her that they must seal the crack with lead and then bury the bomb in a concrete bunker. He explains that this will work because he is from the future and that the Island has not experienced a nuclear blast. As he is explaining this, Sawyer comes up behind Ellie with a rifle and demands that she drop her weapon.
We then go back to a meeting taking place between John and Richard, now holding the compass that Locke gave him. Richard asks how Locke got the compass. Locke says that Richard will give him the compass in the future and that Richard will also refer to Locke as their leader. Richard explains that their leaders are chosen by a "very specific process" and that it starts at a "very very young age". Locke asks the year and is told 1954. Locke says that he will be born in two years (May 30th 1956) in Tustin, California and invites Richard to come meet him. Locke then senses that the time is about to shift and urges Richard to tell him how to get off the island. But before he can get an answer there is another time shift.
1 November 2004
The group finds themselves at a point in time at which Richard's camp does not exist. Daniel, upon seeing Charlotte, rushes over to comfort her, but soon after they are reunited, she begins bleeding profusely from her nose and collapses.
Late 2005 (Flashback)
In a certain coastal town in the Philippines, greeted by a banner that reads "Mabuhay" (meaning "Welcome!" or "Long Live!" in the Filipino language), Desmond is rushing through the beach, looking for a doctor named Efren Salonga. Desmond finally reaches a hut, finding the doctor playing cards. The two then rush to Desmond's boat, and find Penny in active labor. After instructing her to push, Penny successfully gives birth to a baby boy, which leads the couple to kiss and profess their love to each other.
Desmond and his son, Charlie are sitting on their sail boat, and Desmond begins to tell him of a special island he used to live on, a place he hasn't visited for many years. He reveals that the island he is speaking of is in fact Great Britain. He tells Charlie that he is from Scotland, the most beautiful part of Britain, and also where his parents fell in love. Soon after, Penny joins them on deck and tells Charlie that this was also the place where his father broke his mother's heart, and Desmond replies that he had left that bit out.
Desmond tells Penelope that he must find Daniel's mother and tell her that Daniel is still on the island and then Desmond will be done with this for good. But if Daniel told Desmond all this on the island three years ago, Penelope wonders, then why did Desmond just remember it two days ago? Desmond does not have an explanation, but he has a clear memory of Daniel knocking on the hatch door and telling Desmond to go to Oxford because everyone is in danger and Desmond is the only one who can save them. Penny then asks him to promise her he will never go back to the island, to which Desmond replies "Why in God's name would I ever want to go back there?"
Desmond then goes to Oxford in search of Daniel Faraday's records, but the receptionist tells him that there are no records of anyone by the name of Faraday being employed at the University. Suggesting it may be a clerical error, she asks Desmond what year he visited, but he is unable to remember. After snooping around, Desmond finds Faraday's lab where he experimented on Eloise in "The Constant". The door is sealed, but Desmond ignores this. The lab is now dilapidated and abandoned. His old attic laboratory, including his rat maze and chalkboard, is now covered in burlap tarps. A custodian arrives and notices Desmond. He tells him why Oxford is ashamed of Faraday: because he experimented on a live human subject, a young woman.
Desmond tracks down the woman, named Theresa, only to find out that she is in what appears to be a coma, but is in fact in a time trance similar to Minkowski's: her consciousness is traveling through time and cannot be stopped. Theresa's sister warns Desmond of Faraday's cowardice and how he abandoned Theresa, unlike Charles Widmore, who has graciously paid for her medical support. It is then revealed that Widmore subsidized Faraday's research at Oxford.
After his travel to Oxford, Desmond journeys to Widmore's office, barges in, and demands to know where he can find Daniel Faraday's mother. When Widmore dissembles, Desmond reveals that he knows Widmore has financed Faraday's research at Oxford, and paid for Theresa's medical support. Desmond then says that he will not answer any of Widmore's questions but that he only has one question for Widmore, and when he answers it, Desmond will leave him alone. Desmond then proceeds to ask about Daniel's mother's address. Widmore asks if Penny is safe, but Desmond insists on learning the address. Widmore eventually gives Desmond an address in Los Angeles, but tells him that Daniel's mother will not be happy to see him because she is "a very private person." Widmore ends the conversation with a warning that this business has been going on for "many, many years", and begs Desmond to keep himself and Penny out of it and safe by going back into hiding.
Desmond returns to Penny and tells her that Daniel's mother is dead. Penny asks Desmond why he is lying. Desmond reveals that Daniel's mother is in Los Angeles, to which Penny replies that she and Charlie will be going with him.
