Sarah grew up on the wealthier side of the island in Figure Eight and thus is considered a Kook. Her father is a self-made entrepreneur and built the family business from the ground up. Sarah describes him as being like John B when he was younger.
Sarah has an older brother, Rafe, and a younger sister, Wheezie. She lives with her father and her stepmother, Rose, with whom she has a relatively strained relationship. She is close to her father and says that she can't imagine life without him.
In the ninth grade, Sarah was best friends with Kiara, but the friendship ended abruptly when Sarah began to feel claustrophobic in the friendship. She has had a number of boyfriends in the past but no relationship ever lasted. Prior to the pilot she started going out with Topper, who is also a Kook. Sarah is interested in the environment and has an easy-going and fun-loving attitude.
