A "Harry Potter" fan posited that Hermione taught Viktor how to say her name in "Goblet of Fire" so readers could also learn and author JK Rowling confirmed the theory on Twitter. Business Insider reports Twitter user @atulaak posted on Twitter, "Theory: @jk_rowling included that passage on how to pronounce Hermione's name in 'Goblet of Fire' just to school all of us who were saying HER-MY-OWN like Viktor Krum." J.K. Rowling responded, "Theory correct."
