In To Kill a Mockingbird, interpret Jem's healthy appetite when no one else can eat after the events of Chapter 15.
This happened the day after the children followed Atticus to the jail and the mob almost attacked him.
The morning following the scene that takes place outside of the jail finds Jem as the only member of the family with an appetite.
The episode at the jail the previous night can be seen as a victory, orchestrated almost accidentally by Scout.
Scout recognizes a schoolmate's father, Mr. Cunningham, and asks him polite questions about his legal debt to Atticus... Scout's innocent questioning of Mr. Cunningham shames him, and he convinces the men to leave.
Scout herself gives in to the fear and confusion she feels and bursts with tears.
