Emotionally vulnerable, shy, and discreet, Tracey is the complete opposite of her rebellious older sister Anita. Tracey apparently suffers from sexual violence, likely perpetrated by her father Roberto. Perhaps because of this, Tracey, unlike her sister, feels a visceral disgust for sex and often tries to protect her sister from being touched by other people. Tracey’s concern for her sister’s well-being leads her to hate Anita’s boyfriend Sam Lowbridge. Her anger toward Sam leads her to attack him and almost drown in the Big House pond, though she ultimately survives. Later Tracy shows her vengeful side by accusing Sam and Anita of pushing her into the pond, even though it was an accident.
