6x03 MyBabyPhoto

Kate finds a photo of a pregnant Claire.

At the airport, Kate holds the taxi driver at gunpoint and orders him to drive. Claire begs to be let out of the taxi but Kate refuses. When the driver stops in front of Arzt, who is in a crosswalk, picking up his luggage which has fallen in the street, Claire tries to get out, but Kate won't let her. Kate momentarily sees Jack and both look quizzically at each other. Then, they finally get past by running over one of Arzt's bags. On the street outside, the taxi driver flees the car, and Kate takes the wheel. She pulls over and allows Claire to get out, though she refuses to let her get her luggage from the trunk, and then speeds away. Next, Kate stops at a garage and pays a mechanic 200 dollars to remove the handcuffs with a punch press. While there, she searches Claire's bag and discovers a photo of a pregnant Claire, baby clothes and a toy stuffed killer whale.

6x03 HelloNewMommy

Kate and Claire meet the adoptive mother.

Kate, guilty at putting the pregnant woman through the ordeal, drives the taxi back to where she left Claire. She offers to bring Claire to her destination. Claire is initially hestitant, but agrees. The couple that were to adopt Claire's baby had not shown up at the airport, so Claire assumed they had gotten their days mixed up. When they arrive at the house, Claire asks Kate to accompany her inside, much to the latter's surprise. A woman answers the door in tears and tells Claire her husband had just left her. She then tells Claire they cannot take the baby and she is truly sorry. Upon hearing this, Claire becomes upset and goes into labor.

6x03 DoctorGoodspeed

Doctor Goodspeed shows Claire her unborn baby.

Kate drives her to the hospital, where Doctor Ethan Goodspeed asks Claire if she is ready to have her baby, which confuses her. It appears the baby is ready to be delivered, even though it is still slightly premature. Ethan then tells her she can have the baby now or he can give her drugs which are safe and may stop the labor. Claire decides she isn't ready and she will take the drugs. When a monitoring device loses the unborn baby's heartbeat, Claire panics momentarily, crying out, "Is Aaron okay?" Ethan uses an ultrasound to show that the baby had simply changed position and appears to be healthy.

6x03 TakeMyCreditCard

Claire gives Kate her credit card.

Later, Detective Rasmussen and Officer Westly enter the hospital room, searching for Kate. Claire covers for her, claiming she was just a cab driver who helped her into the hospital. After the police officers depart, Kate emerges from an adjoining room and thanks Claire for her help. When Claire asks Kate what she had done, Kate asks "Would you believe me if I said I was innocent?" Claire says she would and, in gratitude, gives Kate her credit card. Claire says she used the name "Aaron" because she "knew it or something," and Kate tells Claire she should keep him. The two wish each other luck as Kate departs.

Original timeline (2007)

At the Temple

6x03 StayWAway

Sawyer declares he is leaving the Temple.

A barefooted Lennon hurries through corridors to tell Dogen the news - Sayid is alive. Jack tells Sayid he died. The last thing Sayid remembers is being shot back at the Barracks. Sawyer is resentful a torturer and child shooter should have another chance and tells Kate he is thinking about running. Sayid's gunshot wound is almost completely healed and he thanks Jack for saving his life. Dogen arrives and asks to speak with Sayid but Jack wants answers first. Dogen sets his men on Jack, Miles and Jin as Sawyer appears and begins firing a gun saying he's leaving. Dogen says he has to stay and they won't hurt his friend, Sawyer replies Sayid is not his friend and leaves saying "Don't come after me."


Dogen tortures Sayid with a red-hot poker

Jack is held at gunpoint by Aldo and told to calm down. Lennon wants to know where Sawyer has gone. Kate claims she can bring Sawyer back. Jin volunteers to go with her. Lennon, still cautious as to whether Kate can accomplish her task asks what makes her think Sawyer will listen to her. Kate replies she can be very convincing when she wants to be.

Once Sayid is in what appears to be Dogen's lab he is strapped down to a gurney. Dogen blows ash over his chest and then hooks him up to an electric generator. Dogen uses the motor to shock Sayid. Dogen stops as soon as Sayid screams in agony and then burns Sayid's abdomen with a red hot poker. Sayid is released and Lennon apologizes and says that this was a test which he had passed. After Sayid has been taken out, Lennon correctly guesses he has just lied about the "test results" on behalf of Dogen.

6x03 FateInHisHand

Jack decides whether or not to give the pill to Sayid.

After Sayid returns and tells Jack he was tortured, Jack demands to enter Dogen's room and, once allowed there without trouble, questions why would he torture Sayid. Lennon translates for Dogen that Sayid has been "infected" — for lack of a better translation of the word Dogen used — and that they were diagnosing him. Dogen then asks Jack to give Sayid a pill which he claims will stop the infection from spreading; when Jack asks why are they tasking him with that, Dogen says it won't work unless it's taken willingly. Jack takes the pill to Sayid who says he will take the pill if Jack thinks he should. After considering it for a while, Jack decides not to give it to him.


Jack about to take the pill

Jack returns to Dogen's room and asks him why he uses a translator when he can speak English. Dogen replies that it helps him maintain a barrier between himself and those he is in charge of. When Jack asks whether Dogen is from the Island, Dogen says he was "brought here" like everyone else. Jack questions this and Dogen replies, "You know exactly what I mean." Dogen then asks why Jack did not give Sayid the pill. Jack answers that it's because he does not know what is in it and repeatedly demands to know its content. Dogen says that Jack will just have to trust him to which Jack sneers, saying he doesn't even trust himself. Exclaiming, "Let's see where trust takes us," Jack then ingests the pill. Dogen promptly tackles Jack and with a desperate Heimlich Maneuver, he manages to make Jack spit out the pill and then he admits that the pill is poison.

Dogen makes tea for Jack and himself. Jack questions Dogen and Lennon about why they wish to poison Sayid. Dogen uses a Japanese word to explain what has happened to Sayid and Lennon says that the closest word for it in English is "claimed". As Jack struggles with the concept, Dogen explains in English that "there is a darkness growing in him and when it reaches his heart, everything Sayid once was will be gone". He does not say what has "claimed" Sayid. When Jack asks how he can be sure, Dogen tells Jack that it was what happened to his sister.

In the jungle and the Barracks

6x03 IWasThatGuard

Kate being confronted by Aldo.

In the jungle, Kate leads Jin, Aldo and Justin after Sawyer. Kate questions what they are trying to protect them from. Aldo states they are protecting them from the "big pillar of black smoke that makes a 'ticka-ticka' noise and looks pissed off." Jin asks about the Ajira flight, which Aldo refuses to talk about and scolds Justin when he insinuates he knows about the plane.

Justin suddenly grabs Kate, preventing her from tripping a wire hidden in the foliage which appears to be connected to one of Rousseau's old traps. Justin seems puzzled about this, exclaiming that Rousseau died "years ago," and is once again cut off by Aldo when he starts expounding on the origin of the trap. Kate demands to know what is Aldo trying to hide. Aldo becomes defensive and hostile, explaining that he's the one Kate knocked out with a rifle butt during the Hydra Island escape three years ago. He argues and harasses her until Kate hits him and springs the trap, incapacitating both Aldo and Justin. Jin is bewildered by these actions, and Kate explains that they are escaping.

Jin wants to know where Kate is going. Kate says she is catching up with Sawyer and that she has no intention of bringing Sawyer back to the Temple nor being a prisoner there. Jin asks where the plane she was on landed, as he wants to find Sun, but she doesn't know. Kate says the Others don't care about any of them. Jin asks, "Who do you care about, Kate?" at which Kate leaves, angrily wishing Jin good luck. She says she will figure out with Sawyer what to do next.

6x03 LordOfTheRing

Sawyer holds onto the ring, before throwing it into the water.

Kate finds Sawyer in the now abandoned house he and Juliet lived in at the Barracks. Kate spies on Sawyer as he removes a box from under the floor boards in the bedroom and takes an unknown item out of the box. He is clearly very upset. Kate turns to leave and causes the floorboards to creak. Sawyer comes out into the hall with his gun raised and is surprised to find Kate there. The scene shifts to Sawyer and Kate sitting at the end of the submarine jetty where Kate explains that she came back to the island to find Claire to reunite her with Aaron. Kate attempts to enlist Sawyer's help in her quest, but Sawyer displays an utter lack of interest in the plan. Kate then apologizes for Juliet's death, as she feels it is her fault. Sawyer, however, blames himself for Juliet's death, admitting that he convinced her to stay on the island with him three years ago (in 1974) because he didn't want to "be alone."
6x03 ClaiRousseau

Claire reappears after 3 years in the jungle.

He says he was going to ask Juliet to marry him, producing an engagement ring from his pocket. Clearly a broken man, Sawyer suggests that perhaps some people are just meant to be alone. He then throws the engagement ring into the water, and proceeds back to his former house at the Barracks. He passes Kate on the way and solemnly tells her she can probably make it back to the Temple by nightfall.

On his way back to the Temple, Jin is attacked by an embittered Aldo who wants to kill him despite Jin's claims of wanting to go back and Justin's reproaches. As Jin attempts to flee, his foot is caught in a bear trap. Just as Aldo is about to shoot him, an unseen person shoots and kills both Aldo and Justin. Jin turns around and is stunned to see that the shooter is a disheveled-looking Claire.



  • Kate was the both the first character to have an episode dedicated to her flashbacks and the first character to have an episode dedicated to her flash sideways - "Tabula Rasa" and this episode. Earlier flashbacks and flash sideways appeared in multicentric episodes.
  • When Hurley asks Sayid if he was a zombie, this is an-inside reference to the running joke on the Official Lost Podcast that the (non-existent) Season 7 will be called "The Zombie Season."

Production notes

Bloopers and continuity errors

  • The credits are not in alphabetical order (as they have always been): Emilie de Ravin comes before Henry Ian Cusick.
  • Kate's dialogue when she hijacks the taxi differs slightly from the dialogue in "LA X, Part 2".
  • In the scene in which Kate gets the handcuffs cut off, what appears to be the date "5-8-09" is marked on the windshield of a car. If that is indeed what is written, it is presumably a production oversight. Typically dates are written on car windshields when they are impounded and/or wrecked. This was probably picked up at a junkyard/auction before filming in 2009.
  • When Kate and Jin say goodbye to Jack, Jin first wears a white shirt when he leaves the screen, in the next shot from above another guy took Jin's place and wears a brown jacket.
  • After Kate beats up Justin and Aldo, she takes their guns with her. However, when they later try to kill Jin, they have both guns.
    • Jin is carrying the rifle and puts it down, then Justin takes it from the ground. It is not entirely clear where Aldo's pistol comes from.
      • Kate takes a Walther P-38 off of Aldo, and when they re-capture Jin, he is holding a Beretta 92
  • Some think that when Kate is going through the hallway in the barrack's house and the camera turns around her, you can clearly see two shadows moving (camera-guy and sound, probably) on the wall.

Aaron's ultrasound showing a date of October 22, 2004

  • We see a small blue thing attached on the upper left part of Claire's body when Ethan first approaches Claire in the Hospital. Moments later, when he wants to have an ultrasound the sensor on her stomach is black and on the right side.
  • During the scene when Sawyer was holding the others at gunpoint his pistol changed. He started out with a Sig Sauer and left with a Glock.
  • The date in Claire's sonogram contains an error and a clue according to a post by Gregg Nations on The Fuselage. One interpretation is that it shows the incorrect month (10-22-04) and should be 9-22-04 (September rather than October) and the clue concerns the year, i.e. 2004. (Nations does not refer to the time at all.) When asked whether the "10" was the clue and the "04" the error, he replied that they were not.
    • The "D:" prefix before the date could mean "due" rather than "date," meaning that Aaron's due date is 10-22-04. This would be mostly consistent with the other timeline, in which Aaron was born on 11-01-04. However, that would not explain why the time "9:29:42 AM" is printed above that date.

  • Midnight Cowboy: Arzt shouts, "I'm walking here. I'm walking here!" This line is from the 1969 film Midnight Cowboy where the same dialogue is delivered verbatim by Dustin Hoffman's character, Ratso Rizzo. The line ranked #27 on AFI's list of the top 100 movie quotations in American cinema. (Movies)
  • Star Wars Episode V: The Empire Strikes Back: After being tortured by Dogen, Sayid says, "They didn't ask me any questions." This is very close to the line, "They never even asked me any questions", spoken by Han Solo after he was tortured by Darth Vader. (Star Wars)
  • Star Trek: Deep Space Nine: Dogen has a baseball placed on his desk. In the TV series DS9, Benjamin Sisko, the commander of the station, used to have a baseball prominently placed on his desk throughout the entire run of the show. In the pilot episode, he used the baseball as a metaphor to explain the nature of linear time to the inhabitants of the wormhole, who experienced time all at once. (TV)
  • Damien: Omen 2: Kate uses the alias of Joan Hart. This is the name of a character in the 1978 film, Damien: Omen 2. In this film, the character of Joan Hart is a reporter who discovers that the identity of the antichrist is a young boy, and subsequently is killed in a bizarre accident. (Movies)
  • Dexter - Claire visits Angel of Mercy Hospital. "Angel of Mercy" is a term for a type of serial killer in the Dexter universe. Dexter Morgan's first kill is an "Angel of Mercy" who was a nurse at Angel of Mercy Hospital. The hospital is seen in several episodes. (TV)

  • Sayid the torturer is himself tortured. (Irony)
  • Ethan, in the flash-sideways timeline, says that he doesn't want to stick a bunch of needles into Claire if he doesn't have to, which is exactly what he does to her in the original timeline. (Irony)
  • Claire reappears after 3 years in the jungle. (Plot twist)
  • Ethan jokes that Aaron 'likes to move around' and he is going to be a 'handful'. In the original timeline, Aaron has already moved between several mothers at such a young age (Claire, Kate, then Carole Littleton) and has been one of the many problems the survivors have had to deal with on and off the island. (Irony)
