Differences from the Light Novel

 * Zircon Tower is evacuated and abandoned. Fanis and the refugees are stationed near Faltra.


 * The chronological order of events have been significantly altered for the rest of the episode.
 * While Diablo does return to Faltra to check up on Klem, the events in the episode occur after Diablo's visit to Greenwood.
 * As such, Lumachina, Horn, and Rose are not present. Even Emile is traveling the land, honing his skills as a warrior.
 * There are scenes that only occur in the anime.
 * Diablo does not get alluded to being a hero by Klem.
 * There is no rap bit from the people grateful to Klem.
 * Edelgard works in her Fallen attire in the café.
 * The encounter with the gang occurred at a restaurant, not the bakery.
 * The gang members were harassing businesses for protection money, not trying to sell a pig ornament.
 * The bath scene between Diablo and Klem is omitted as are subsequent events that would cause inconsistencies in the timeline.
 * The ending scene alludes that the anime may go in a different direction from what transpires in the novels.
