Ernie Macmillan attended Hogwarts and was sorted into Hufflepuff, where he became friends with Hannah Abbott, Susan Bones and Justin Finch-Fletchley. He suspected that Harry Potter might be the heir of Slytherin, as he heard Harry speaking Parseltongue at the Duelling Club. He later realized that Harry was not the heir when he found out that Hermione Granger was petrified, as he knew that Harry would never harm his best friends, and gave a public apology to Harry. Ernie supported Cedric Diggory during the Triwizard Tournament as Cedric was from his house of Hufflepuff. He later believed in Harry that Voldemort had returned when Cedric Diggory was killed. Ernie joined Dumbledore's Army and was a great Hufflepuff member. His support for Harry was so strong that he was with the Dumbledore's Army until Voldemort was killed.
