what does he think about cassie's scuffle with lillian jean simms

In Chapter Six, Cassie tries to tell Uncle Hammer about her day in Strawberry but Big Ma keeps interrupting her. Finally, she tells him the whole story, and Uncle Hammer wants to know if it was Charlie Simms who knocked her off the sidewalk. He jumps up, saying he has his own gun when Mama glances at her husband's shotgun, and runs outside. Mama tries to stop him, but he takes off in the Packard. Mr. Morrison jumps in with him right as he is pulling away.
