Supporting cast dynamics refer to the relationships, interactions, and individual character arcs of secondary characters that enhance the main narrative and contribute to the overall tone and theme of a series. These dynamics are crucial as they help define the unique voice of a show, showcasing how secondary characters support or challenge the protagonist while enriching the storytelling through their own subplots. The way these characters interact can also be pivotal in crafting a compelling series bible that outlines the show's premise and character relationships.
