* Kenny's growing awareness of racial prejudice and the dangers it poses: Kenny is becoming more aware of the realities of racism, especially after witnessing the brutal attack on a Black man in Flint, Michigan. He wants to protect his brother, Rufus, from harm, and this makes him overly protective and sometimes even critical of Rufus's behavior.
* Rufus's impulsiveness and mischievous nature: Rufus is a rambunctious and energetic child who often gets into trouble. His recklessness and lack of caution worry Kenny, who fears he will become a target of racial violence.
* The changing dynamics of their family: The family's move to Birmingham, a city where racial tensions are high, adds a new layer of stress and anxiety to their relationship. The fear of violence and the constant reminder of the dangers Black people face in the South weigh heavily on both brothers.
* Kenny's growing maturity and Rufus's immaturity: Kenny is maturing quickly and becoming more responsible, while Rufus remains a child with a short attention span and a tendency to act without thinking. This difference in maturity leads to misunderstandings and conflicts.
These factors combined create a tension between the brothers, leading to arguments and moments of frustration. While Kenny's concern for Rufus is understandable, his protectiveness can sometimes come across as condescending and suffocating, further straining their relationship.
