Flash-sideways timeline (2004)
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. 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 looks quizzically toward him. 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. Kate stops at a garage and pays a mechanic 200 dollars to remove the handcuffs with a punch press. She searches Claire's bag and discovers a photo of a pregnant Claire, baby clothes and a toy stuffed killer whale.
Kate drives back to where she left Claire to find her waiting at a bus stop. The couple that were to adopt Claire's baby had not shown up at the airport. Claire thought that they had gotten their days mixed up. Kate offers Claire a ride to the couple's home. Claire is hesitant at first but then decides to go with her. When they arrive at the house, Claire asks Kate to accompany her inside. A woman answers the door in tears, as her husband had just left her. She tells Claire they can not take the baby and she is truly sorry. Claire becomes upset, and goes into labor.
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 he 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.
Claire is looking at her ultrasound which is dated October 22, 2004 at 9:29:42am, one month after the crash of Flight 815 in the original time line. Detective Rassmussen and a police officer 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)
Inside The Temple
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 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 his 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".
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 on behalf of Dogen.
After Sayid returns and tells Jack he was tortured, Jack demands to enter Dogen's room and, once there, questions why they would torture him. Lennon and Dogen explain that Sayid has been infected and that they were diagnosing him. Dogen then asks Jack to give Sayid a pill which he claims will cure him and stop the infection from spreading. Jack takes the pill to Sayid who says he will take the pill if Jack thinks he should. Jack decides not to give it to him.
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 says because he does not know what is in it. Dogen says that Jack will just have to trust him. Jack says he doesn't even trust himself so how could he trust Dogen and then takes the pill himself. Dogen promptly tackles Jack to stop him from ingesting it and then admits the pill is poison.
Jack questions Dogen and Lennon why they would want to poison Sayid and they tell him that "a darkness" has taken Sayid's body and when it reaches his heart, the man Sayid is will be lost. When questioned how he knows this, Dogen tells Jack that it happened to his sister.
Search Party and Barracks
In the jungle, Sawyer is tracked by Kate, Jin, Aldo and Justin. Kate questions why they are trying to protect them. Aldo states it is from the "big pillar of black smoke that makes a tick tick noise and looks pissed off". Jin asks about the Ajira flight, which Aldo refuses to talk about.
Kate narrowly avoids tripping a wire hidden in the foliage which appears to be connected to one of Rousseau's old traps. Aldo confronts Kate about attacking her during the Hydra Island escape three years ago, he argues with her but Kate hits him and springs the trap, knocking out both Others. She tells Jin 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 Kate has no knowledge of where the plane landed. 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.
Kate finds Sawyer in the now broken down house he and Juliet lived in at the Barracks. Kate spies on Sawyer as he removes a box from under the floor boards. Sawyer is very upset. We then see them at the end of the Jetty. Kate explains that she came back to the island to find Claire to reunite her with Aaron. Sawyer blames himself for Juliet's death for convincing her to stay. He says he was going to ask her to marry him. He throws the ring that was in the box into the water and says that Kate can probably make it back to the Temple by nightfall.
On his way back to the Temple, Jin is attacked by Aldo and Justin. As he attempts to flee, he is caught in a trap, and 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.
