Brenda is first seen exiting the Los Angeles airport with Nate Fisher. The two have sex in a janitor's closet before Nate receives news that his father has died. The two part ways but continue their sexual relationship. She is now a shiatsu massage therapist, operating out of her home. Her relationship with Nate continues to grow more serious until Billy emotionally invades her relationship. Billy is a photographer who is often in and out of mental institutions. He exhibits extreme possessiveness over Brenda and even begins stalking her and Nate. The two share corresponding tattoos on their lower backs: Brenda's is the name "Nathaniel", Billy's is the name "Isabel". These names are taken from their favorite childhood book series "Nathaniel and Isabel". Billy's obsession with Brenda eventually spirals out of control when he quits taking his medication and removes his tattoo by cutting his skin off. He attempts to remove Brenda's tattoo before she knocks him unconscious and has him institutionalized.
