Nero re-appears in "The Penultimate Peril" when he, along with Mr. Remora and Mrs. Bass staying in room 371 at the Hotel Denouement and are invited to a cocktail party hosted by "J.S." and Esmé Squalor. When being taken by a disguised Sunny to the Hotel Denouement's Indian restaurant run by Hal, Nero expresses interest to perform his violin at the cocktail party so that his musical genius can be recognized and he can resign as vice-principal. When Nero hears from Hal that they don't serve candy in his restaurant, Nero comments that he won't have anything. When Dewey Denouement is accidentally killed during a confrontation with Count Olaf which woke up all the patrons, Nero mimics what Mr. Remora claimed about the Baudelaire children and claims that Violet and Klaus failed all the tests and weren't good students while Sunny was the worst administrative assistant. During the blindfolded trial, Nero submitted administrative records as evidence. When Count Olaf starts the fire at the Hotel Denouement, Nero and Mr. Remora were last seen wandering the seventh story as Nero starts to worry about his violin case.
