Rowling's commentary and supplement
In an interview,[10] online chat,[11][12][13] the Wizard of the Month section of her website, and during her 2007 U.S. Open Book Tour, Rowling revealed additional character information that she chose not to include in the book. The first bits of information were about the trio and their families, starting with Harry.
She said that Harry became an Auror for the Ministry of Magic, and was later appointed head of the department. He also kept Sirius Black's motorcycle, which Arthur Weasley repaired for him, but he can no longer speak Parseltongue after the destruction of Voldemort's soul fragment within him. She also said that Ginny Weasley played for the Holyhead HarpiesQuidditch team for a time, then leaving to establish a family with Harry, and later became the lead Quidditch correspondent for the Daily Prophet. Ron Weasley worked at George's store for a time, Weasleys' Wizard Wheezes, and then joined Harry as an Auror. Hermione found her parents in Australia, and removed the memory modification charm she had put on them for safety. Initially, she worked for the Ministry of Magic in the Department for the Regulation and Control of Magical Creatures, greatly improving life for house elves. She later moved to the Department of Magical Law Enforcement and assisted in eradicating oppressive, pro-pureblood laws. She was also the only member of the trio to go back and complete her seventh year at Hogwarts. Rowling then went on the explain that Dumbledore's relationship with Gellert Grindelwald extended beyond mere friendship; indeed, Rowling has revealed that "Dumbledore is gay, actually",[14] and harboured romantic feelings for Grindelwald.[15] Next, Rowling revealed the fate of Voldemort. After his death, he was forced to exist in the stunted form Harry witnessed in the King's Cross limbo, as his crimes were too severe for him to become a ghost.
Rowling also explained the fates of several secondary characters, starting with the Weasleys. George Weasley continued his successful joke shop. George married fellow Quidditch player Angelina Johnson and had two children: a son named Fred, in memory of his late twin brother, and a daughter, Roxanne. Next, Rowling proceeded to explain Luna Lovegood's future, saying that she searched the world for odd and unique creatures. She eventually married Rolf, a grandson of the famed naturalist Newt Scamander[13], writer of Fantastic Beasts and Where To Find Them. They have twins called Lorcan and Lysander. Her father's publication, The Quibbler, has returned to its usual condition of "advanced lunacy" and is appreciated for its unintentional humour.
Rowling then gave briefer histories on some more of the minor characters, as follows. Draco Malfoy married Astoria Greengrass and had a son named Scorpius. Percy Weasley married a woman named Audrey and had two daughters, named Molly and Lucy. Firenze was welcomed back into his herd, who finally acknowledged the virtue of his pro-human leanings. Dolores Umbridge was arrested, interrogated, and imprisoned for crimes against Muggle-borns. Cho Chang went on to marry a Muggle.[16] Neville Longbottom became professor of Herbology at Hogwarts and married Hannah Abbott, who became the landlady of the Leaky Cauldron.[17] Bill and Fleur Weasley had a total of three children, a younger son named Louis, and two daughters, named Dominique and Victoire.
Rowling also revealed further transformations in the wider wizarding world as follows. Kingsley Shacklebolt became the permanent Minister of Magic, with Percy Weasley working under him as a high official. Among the reforms introduced by Shacklebolt, Azkaban no longer used Dementors. Harry, Ron, and Hermione were also instrumental in reforming the Ministry.[11] At Hogwarts, Slytherin House became more diluted and no longer held the title as the pure-blood bastion it once was, although its dark reputation lingered.[11] Voldemort's jinx on the Defence Against the Dark Arts position was broken with his death, and there was a permanent Defence Against the Dark Arts teacher stated. Harry also is said to come to the Defence Against the Dark Arts class to lecture several times a year.[10] Lastly, Rowling says that a portrait of Severus Snape, who briefly served as Hogwarts Headmaster, had not appeared in the headmaster's office, as he had abandoned his post. Harry then ensures the addition of Snape's portrait, and publicly revealed Snape's true allegiance.[11]
