Season: 1-5, Episodes: 54, Faction: Survivors
Aaron Littleton (known to the world as Aaron Austen) was born on the Island, and was the son of Claire Littleton and Thomas; the grandson of Christian Shephard and Carole Littleton; half-nephew of Jack Shephard; and great-nephew of Lindsey. Before making a fatal mission to the Looking Glass, Charlie Pace acted like a father to Aaron, and passed on to him his family heirloom ring. Aaron was left behind by Claire in the jungle for unknown reasons when she followed his grandfather, and Aaron was passed through multiple survivors (Sawyer, Kate, Sun) until he made it to the freighter where he was then picked up by the helicopter. When the Oceanic Six made it to the mainland, Kate presented Aaron as her son to the public. For a few days, Jack read bedtime stories to Aaron, hoping to become a surrogate father before getting a message from Charlie that he wasn’t supposed to raise him. Kate then lived alone with him in California and was warned by visions of Claire, his real mother, not to take him back to the Island. Neither Charlie nor Claire used Aaron’s name when admonishing Jack and Kate. After 3 years of living with Kate, Aaron was handed over into the care of his maternal grandmother, Carole Littleton, Claire’s mother, until Claire returns to care for her son. Sometime later Aaron was reunited with both birth mother, Claire and adoptive mother, Kate.
5×01 – Because You Left
Aaron’s infancy caused him to remain unaware of the dangers that were posed to him as a part of the Oceanic Six, but also he was unaware of the need for the six to return to the Island. But his domestic life was due to be shaken when an attorney paid Kate a visit and told her that he had a court-signed order to get blood samples from Aaron and Kate to determine their blood relation. Realizing someone knew her secret, Kate quickly packed her bags and told Aaron they were going “on vacation” and the two abruptly left her house. (“Because You Left”)
5×02 – The Lie
While running, Kate learned that Sun was in L.A. and took Aaron to her, where Sun suggested that Aaron and Ji Yeon should meet. Kate confessed her troubles with the lawyer to Sun who agreed to care for Aaron as she sorted it out. (“The Lie”)
A vision of Ana Lucia appeared to Hurley and assisted him with his transfer of Sayid.
5×05 – This Place Is Death
During this time, Jack and Kate started to believe that Carole Littleton was Norton’s client, although they were eventually proven wrong. As some of the Oceanic Six gathered with Ben Linus on a pier, Kate learned that he was the client trying to take Aaron because he isn’t her son. (“The Little Prince”) Aaron remained with Sun as she arrived at the pier and prepared to enact her revenge on Linus. Kate then took Aaron from Sun’s car and both left the pier after Kate learned that Jack intended to persuade her to return to The Island. (“This Place Is Death”)
5×11 – Whatever Happened, Happened
Leaving the pier, Kate and Aaron drove through the night to visit Cassidy and Clementine. Along the way, they stopped at a supermarket to buy Aaron something to drink, and Aaron wandered off. Kate looked frantically around the store, enlisting the help of the manager, but susequently found him with a woman resembling Claire, who had been about to bring him to the front desk to make a lost child announcement.
The next morning, Kate and Aaron arrived at Cassidy’s house. The door was answered by Clementine, now a young girl. Kate told Cassidy about the events of the previous night, relaying how, on losing Aaron, her first thought was, “it’s about time” as though she had been expecting to lose him all along. Cassidy helped her realize that this was because she had taken him in the first place, and had been using Aaron to console her loss of Sawyer.
That night, Kate checked in at the hotel two doors down from where Carole Littleton was staying, and told her that Aaron was her grandson and that Claire was still alive on the Island. She then turned Aaron over to her care, saying that she would be going back to the Island to find Claire and bring her home. Crying, Kate kissed Aaron goodbye a final time and left. (“Whatever Happened, Happened”)
5×06 – 316
Later that evening, Kate appeared in Jack’s apartment, visibly upset. When Jack questioned about Aaron’s whereabouts, Kate demanded that Jack never again mention Aaron’s name or ask about him if Jack wanted Kate to return to the Island with him. (“316”)
6×08 – Recon
When Claire, his real mother, attacks Kate, who he believes is his mother, MIB says Aaron now has a “Crazy Mother.” (“Recon”)
After the Island
Claire and Kate both escaped the island. It is assumed Aaron was reunited with both his birth mother, Claire and adoptive mother, Kate. It is known from Kate’s promise, that both Kate and Claire raise Aaron.
In the flash sideways world, Aaron was conceived somewhere around mid-January 2004. His mother, Claire, was native to Australia, and he was likely conceived there. Claire was the daughter of Christian Shephard, making him the nephew of Jack Shephard.
6×02 – LA X, Part 2 | 6×03 – What Kate Does
At some point during her pregnancy, Claire contacted Mr. and Mrs. Baskum, a married couple who expressed interest in adopting Aaron. She took photographs of herself, a plush whale, and other baby supplies with her when she decided to fly to America to meet the Baskums.
After Oceanic flight 815 took Claire to Los Angeles, she was briefly held hostage by Kate Austen, released and then traveled with Kate to meet Lindsey Baskum. After Claire discovered that the Baskums would no longer be able to adopt Aaron, Claire began to undergo contractions, and was rushed by Kate to Angel of Mercy Hospital.
At the hospital, Claire was taken care of by Dr. Ethan Goodspeed, who informed her that they were willing to deliver the baby that night if she would like. After Claire decided to postpone the delivery, Aaron’s heart monitor flat-lined, which after readjusting the ultrasound, was determined simply to be Aaron shifting his position. It was during this flat-line that Claire inexplicably asked “Is Aaron okay?” She later was unable to understand where she came up with the name Aaron. Claire was given drugs, and her labor was slowed to further delay Aaron’s birth. (“What Kate Does”)
6×17 – The End
At the benefit concert, Claire went into labor. Charlie arrived backstage and Kate sent him for water and blankets. Kate encouraged Claire to start pushing, but Claire was still not ready and frightened. Kate was scared too. As Claire pushed, the two of them remembered Aaron’s birth on the Island. Aaron was born. Charlie arrived with the blanket and Kate told him to give it to Claire. Claire took Charlie’s hand, and he too remembered their time spent on the Island. Claire, Charlie, and Aaron were present as a family at the church where they moved on together with their friends from the Island. (“The End”)
