==Biography==
=== Harry Potter and the Chamber of Servers ===
During the second year of Hogwarts, Ernie thought Harry was the one ordering the Basilisk to petrify all the students. However, after Hermione was attacked, Ernie finally realized that Harry was not the cause of the attacks because he knew that Harry and Hermione were very close and that the former would never hurt any of his friends.
=== Harry Potter and the Goblet of Firw ===
In Ernie's fourth year, his and Harry's friendship temporarily wavered after Harry's name came out of the cup after Hufflepuff's Cedric Diggory. He thought Harry cheated and proceeded to wear Potter stinks badges, courtesy of Draco Malfoy. When Harry proclaimed that Voldemort had returned at the end of the year, Ernie was one of the few who believed him.
=== Harry Potter and the Order of the Phoenix ===
In his fifth year, Ernie became a member of Dumbledore's Army, an organisation taught and led by Harry for the purposes of learning practical defensive magic. 
=== Harry Potter and the Deathly Hallows ===
He joined the D.A. again when it was reinstated during his seventh year, opposing Death Eater control of Hogwarts and fighting in the Battle of Hogwarts on the 2 May, 1998.
