These sessions provide a safe space for her to process her trauma, beginning to understand the root causes of her anger and destructive behaviors. The narrative slowly uncovers the layers of trauma affecting Kate, including her past experiences of abuse and neglect that have shaped her present-day actions. The process of confronting these memories is depicted as painful but ultimately necessary for healing.
