Parallel 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.

Ethan helps Claire with her 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 labour. 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 somehow "knew" it should be, 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 dust over his chest and then hooked 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 apologises 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 but Jack decides not to give him it.

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 if Dogen is from the Island, he replies that he was "brought here" like everyone else. When Jack questions this, Dogen replies, "you know what I mean". Dogen then asks why Jack did not give Sayid the pill to which Jack demands to know what is in it. Jack then 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.

On his way back to the temple, Jin is attacked by Aldo and Justin. Jin is caught in a trap, and an unknown person saves Jin, killing Aldo and Justin. Jin turns around and is stunned to see it was Claire looking very different from the last time we saw her.

Episode references

  • The title of this episode is a nod to the Season 2 episode "What Kate Did". Both episodes were directed by Paul Edwards.
  • The stuffed animal Kate finds in Claire's luggage is the same stuffed orca whale Aaron is carrying as a toddler when Kate and Jack fight about him. ("Something Nice Back Home")
  • Sawyer throws the engagement ring he planned to give to Juliet into the water, similar to what Desmond had done eleven years before. ("Flashes Before Your Eyes")
  • Kate reuses an old alias, "Joan Hart". ("Born to Run")
  • One of the methods of torture that Sayid endures is electricity. Similar to when he was tortured by Rousseau who used the same method. ("Solitary")
  • Lindsey Baskum and her husband are supposedly the couple in Los Angeles who were very eager to adopt, as found by Richard Malkin. ("Raised by Another")
  • When Sawyer fires his gun to get everyone's attention at the Temple it's a nod to the way he did the same thing after he acquired all the guns in "The Long Con".
