Harry Potter and the Goofs and Trivia.| The script originally said that Hermione would hug Harry and Ron in the final scene. As the then 11-year-old Emma Watson was embarrassed about having to hug the boys in front of the entire cast, Chris Columbus allowed her to change the scene so that Hermione just hugs Harry then starts to hug Ron but the two get embarrassed and resolve to only shake hands.
Her hesitation with Ron is also taken by fans as a precursor to the relationship that will develop between the two characters.
