This time to USA Today. I wish they’d gotten her to talk more about Deathly Hallows. This is probably the most interesting quote:
“I’m sort of writing two things at the moment,” she says. “One is for children and the other is not for children. The weird thing is that this is exactly the way I started writing Harry. I was writing two things simultaneously for a year before Harry took over. So one will oust the other in due course, and I’ll know that’s my next thing.”
“Harry and Ron utterly revolutionized the Auror Department,” Rowling said. “They are now the experts. It doesn’t matter how old they are or what else they’ve done.”
Personally I don’t see how Ron and Harry could have become Aurors without finishing another year at Hogwarts, given the rigorous academic requirements. So I’m going to assume they went back. I’m a little impressed that Ron squeaked in even with that final year, and a letter of recommendation from Kingsley Shacklebolt.
