Shortly after the Oceanic six's rescue,[N 1]Kate Austen and a baby Aaron visit Cassidy,[N 2] who is an ex-girlfriend of James "Sawyer" Ford. Kate gives Cassidy and Sawyer's daughter Clementine (Olivia Vickery) money from the severance pay from Oceanic.[N 3] Cassidy deduces that Aaron is not Kate's baby, prompting her to tell her the truth about everything that happened on the island. Cassidy eventually leads Kate to realize that the reason she took Aaron as her own, is because Kate needed him in order to get over her emotional attachment to Sawyer. After the survivors's confrontation with Ben,[N 4] Kate momentarily loses Aaron in a supermarket. She recovers it from a woman who bears a strong resemblance to Claire Littleton (Emilie de Ravin), Aaron's mother. After this, she decides to return to the island with the others who left. She leaves Aaron in the care of Carole Littleton (Susan Duerden), Aaron's biological grandmother. Kate also tells Carole that she is returning to the island to find Carole's daughter, Claire, and bring her home.
Kate goes to the sick bay where Ben is being treated and donates her blood because she is a universal donor. She strikes up a conversation with Ben's father, Roger (Jon Gries), who is upset that Ben stole his keys and freed Sayid from the jail. Once it becomes clear that Ben will succumb to his injuries without further intervention, Kate decides to take Ben to the Others, the island's native population. Sawyer comes to Kate's aid and they bring Ben to Richard Alpert (Nestor Carbonell), who warns them that if he treats Ben, he will not remember what has happened and will never be the same again. They agree anyway. Another Other urges Richard to inform "Ellie" of his intentions and implies that "Charles" will not be pleased if he finds out, but Richard says he doesn't answer to either of them. Richard then carries Ben into the temple.[N 8]
