J.K. Rowling, according to
Harry Latino, gave more information from a previous interview about Albus Potter and her reasons for avoiding Quidditch scenes if she were to ever write an eighth book; as well as why Harry, Ron, and Hermione reacted the way they did in the climax of
Harry Potter and the Order of the Phoenix when they first encountered the veil in the Death Chamber.
Quidditch seems to be a major factor that is hindering Jo from writing an eighth book (roughly translated from Spanish):
Quote:
"What I keep away from Hogwarts in the next generation is having to return to Quidditch, unless it decides that my hero on this occasion could not play Quidditch. In that case, could have adventures while others play Quidditch."
Jo also discusses the trio's reactions towards the Veil introduced in
Order of the Phoenix:
Quote:
"I wanted to have a debate here, so that my three main characters (when they arrive in the room where they studied death in the Ministry of Magic). Hermione, the hyper-rational and skeptical one until the end, did not hear anything behind the veil and it frightens her; Ron gets tense: Ron is not someone who would face something deeper than a beer, to be able to avoid it; Harry has accepted it, and here he is slightly unwise, because Harry has no idea how dangerous the attraction of death can be for a teenager."
