In what is perhaps the biggest red herring in recent years, there was absolutely nothing special about Martys daughter, Audrey Hart. Throughout the season, we received and studied an insane amount of hints towards Audreys involvement with the cult. It began early in the season when Audrey is caught with vivid drawing of a naked man and woman participating in sexual activities. Shortly after, Marty stumbles upon a reenactment of five male dolls ready to rape a female doll. As well, the symbol of the cult could be seen drawn in the Hart Family house. These huge side-points led us to believe something strange was happening to Audrey. Her behavior began after her stay with her Grandfather. Many believed Martys step-father was a member of the cult as well. The hints and foreshadowing did not end there though. Later in the series, Audrey was seen wearing a yellow crown. Note, this scene came minutes before the revelation of the Yellow King and Carcosa. The yellow crown is a major theme in the book The King in Yellow. Alas, nothing came of this seemingly important plot-line. Its a little hard to swallow that this was just a case of bad parenting. As for Cohles daughter, the circumstances behind her death was never fully explained. All we know is she was killed by a car as she was riding her tricycle. The main theory is the identity of the driver was a drunk Rust. The accident destroyed his marriage and his mind over the years. Along with his heavy drug use, the locks on his sanity were finally broken when a druggie injected his own infant daughter with heroin. It makes perfect sense and explains why he has such an overly nihilistic view on life. Imagine how much deeper Cohles moment of peace would have been after he finally learned to live with himself.
