Final answer:
Aunt Alexandra does not directly discuss the trial with Atticus in Chapter 15 of 'To Kill a Mockingbird.' The chapter instead centers on Atticus facing a mob at the jailhouse prior to the trial.
Step-by-step explanation:
In To Kill a Mockingbird, the character Aunt Alexandra does not specifically speak to Atticus about the trial in Chapter 15. Instead, this chapter is focused on the tense night before the trial when a mob arrives to lynch Tom Robinson. Atticus stands guard at the jailhouse, and the children, Scout, Jem, and Dill, arrive, inadvertently diffusing the situation. Aunt Alexandra's views on the trial are more indirectly conveyed through her concern for family reputation and her disapproval of Atticus's actions in defending Tom Robinson, which we see in other parts of the book. Alexandra represents the traditional and prejudiced views of many white residents of Maycomb, Alabama, which conflict with Atticus's moral stance on justice and equality.
