Who is the main antagonist in Denny's custody struggle?

The main antagonist in Denny's custody struggle is indeed represented by his in-laws. They play a significant role in the narrative, as they are depicted as opposing Denny in his efforts to gain custody of his daughter, Zola. Their motivations are driven by a desire to protect Zola and their belief that Denny, despite his good intentions and love for his daughter, is not fit to be her primary guardian.

Denny's in-laws challenge him legally and emotionally, adding tension and conflict to the story as they attempt to undermine his role as a father. This dynamic highlights the theme of family relationships and the lengths to which individuals will go to protect their loved ones, even when it puts them at odds with their own family members.

Other options do not serve as the main source of antagonism in the custody battle. While Denny's lawyer plays a supportive role, their position is not adversarial. A rival race car driver is also not involved in this personal conflict, as their relationship is separate from the custody challenge. The state typically serves as a neutral party in custodial matters rather than an antagonist. Thus, the focus on Denny's in-laws accurately aligns with the central conflict surrounding his custody struggle.
