Quint Dunn is the son of Richard Dunn and an employee at SWERY 65. He is also Becky's boyfriend and a good friend of Anna. It is implied that he either makes or obtains a red powdered drug (possibly from the red seeds), which he sells and uses to buy an engagement ring for Becky. He is the first person to discover Becky's body but is immediately cleared as a suspect.
His favorite hobby is to tinker with his bike, something he never actually rides. Quint also drives Sallie Graham back and forth between the bar and her house on occasion to try and help her with her grief.
- Quint has a "Q" on his hat.
- Quint's drink menu is, just as with Keith and Lilly Ingram's item lists in the Milk Barn, different from his fathers drink menu.
