10 Harry Potter Mysteries JK Rowling Has Actually Answered
5. Did The Trio Ever Go Back To Hogwarts?
In an interview with the same website, JK Rowling divulged a huge slice of the futures of her characters - which of course have now been made far fuller since the production of The Cursed Child. Perhaps surprisingly, the only one of the trio to return to complete their education was Hermione. "I mean, come on," Rowling laughs in the interview, "Nobody's going to think Hermione wouldn't go back."
Harry and Ron, however, went straight into the Auror Department to help new Minister For Magic Kingsley Shacklebolt. As Rowling explains,
Kinglsey would have wanted Ron, Neville, Harry, and they would've all gone, and they would've all done the job. And I think that would've been a good thing for them too, because to go through that battle, and them be relegated to the sidelines, I think they would've felt a need to keep going, and finish the job. So they would've have been rounding up the corrupt people who were doing a Lucius Malfoy, and trying to pretend that they really weren't involved.
Bonus Fact: Harry remained an Auror and became Head of Department by the time of The Cursed Child, 19 years after The Deathly Hallows. Ron went on to work with his brother George in Weasley's Wizard Wheezes and Hermione worked to improve House Elf rights in the Department For The Regulation And Control Of Magical Creatures and would go on eventually to become Minister For Magic.
