How does scout feel differently once the trial has started from how she felt earlier in the morning while thinking about the incident at the jailhouse? how do you explain the change?

Toward the begin of Chapter 16 of Harper Lee's To Kill a Mockingbird, once in bed in the wake of having confronted a horde encompassing her dad, Scout at long last starts to comprehend that night's risks and begins crying. Preceding that minute, she had just comprehended that her dad was conversing with a gathering of men before the jailhouse. Atticus' apparently quiet attitude is somewhat in charge of her prior innocent elucidation.
