Who had the kind gesture of bringing Avery a milkshake?

The kind gesture of bringing Avery a milkshake was done by a guard. This act highlights a rare moment of compassion in an otherwise harsh environment. It illustrates the significance of small acts of kindness that can have a profound impact on individuals experiencing the difficulties of incarceration. Throughout the narrative in "Just Mercy," Stevenson emphasizes the humanity present even among those who work within the criminal justice system. While other characters, like Avey's attorney or family members, are certainly supportive in their own ways, it is the guard's unexpected act that stands out as a demonstration of empathy and care within the confines of the prison. This reflects the theme of seeking mercy and understanding for those who are often marginalized, even by those in positions of authority.
