Paul listens to the last tape; David leaves Juanita, but she soon comes back, addicted and begging for help. He agrees to help her out, providing her a drug fix in exchange for rough, demeaning sex. The humiliation and disgrace shatter her dreams and causes her severe emotional distress, thus making her addictions even stronger. After a while, she demands that he pay for her entrance to rehabilitation or else she'll call the police. Enraged, David decides to do the same thing he did to Edna: mix her heroin with car battery acid, resulting in a fatal seizure for her. Through a flashback, it is revealed that David is the biological father of Mike, who is also Edna's child, and that David brutally hit him before poisoning Edna (which explains the scar on his face). The tape ends with David speculating on how his return to the East Coast will bring about his redemption with Moon and tie the loose end with Edna's child, who he is completely unaware of as Mike in their second encounter.
