Nero is also very fearful of the zombies and especially Margwas around him despite having some knowledge of the supernatural. This knowledge comes from his book that he keeps in his room about how the Keepers protected the world from the Apothicons. Despite murdering his wife in cold blood, as well for the life insurance payments, he seems to be the most regretful and merciful of the crew, although not above justifying his actions by stating that no matter what, he was never enough for his wife.
