Fifteen Reasons Why and the Crimes of Crouch: Part 1

The Battle of Hogsmeade

 * Alyssa White is omitted from the majority of the battle, because she was tortured and injured during interrogation, which took place prior to the battle versus in the books, she was tortured shortly before the battle's end. However, she does reappear moments before the end of the battle to witness the Dark Lord's demise.
 * Because of the omissions, Christopher Lewis took her part during the Wooden Bridge scene. Also, her friends that were standing at the other end of the bridge were omitted and were replaced with his past crushes including Alyssa White's sister.

Preparations for the Battle

 * Alison Black, despite the breakup, is the one that brings down the Wooden Bridge, whereas in the books, it is Katherine Green that does it.

The Final Duel

 * In the films, Christopher and Voldemort duel in the Great Hall instead of the Viaduct
 * Because of this relocations, the students are watching the duel.
 * A scene is added where students like Alyssa White, and her "comrades" appear behind the door to the Trophy Room in the Great Hall.
 * The scene where Alyssa White mutters words during the final battle is added. Something that never is seen in the books.

Behind the Scenes

 * During the Covered Bridge fight scene, when Christopher is sprinting down the bridge, the actor underwent strict and serious training on sprints in rugged terrain such as this scene.
