Exposing Evil Plans and Evidence

In any story, there comes a time when the hero or heroine reveals the villain's evil plans and evidence of it. He or she can do it in many ways:
 * Interrogating the villain or his/her henchmen.
 * Discovering evidence of the villain's handiwork and original nature/backstory.
 * Unmasking the villain.
 * Revealing his/her evil plans to the citizens or their loved ones.
 * Understanding what the bad guy wants.
 * In some cases, the villain might unintentionally expose himself/herself (for example, Darla Dimple unintentionally exposes herself as a spoiled, rotten, bratty monster who intended to drown Danny Cat and his friends when she flooded the stage to the public during a movie premiere).
