• Percy is acting entirely of his own accord. [Read the exact quote from World Book Day, 2004]

• Arthur Weasley will not be the new Minister of Magic. [Read the exact quote from Jo's website]
• In 'Chamber of Secrets,' what would have happened if Ginny had died and Tom Riddle had escaped the diary? JKR: cannot answer except to say Voldemort would have been stronger. [Read the exact quote from Jo's website]
• Mafalda: was a Weasley cousin whose character was edited out of the books in favor of Rita Skeeter. [Read the exact quote from Jo's website]

• When JK answered the question (see above) about Charlie and Bill’s ages, she got it wrong.

[Read the exact quote from Jo's website]
• Fred and George never noticed Pettigrew on the Marauder's Map because they didn't know who he was. Even if they had recognized his name, they would have assumed he was just a student with the same last name. Pettigrew was one of many moving dots on the map, and Fred and George would have only been focused on the path their mischief took that day. [Read the exact quote from Jo's website]
• Fred and George’s names did not come from the twins in "Gone with the Wind," they were chosen to fit with the old fashioned names of their brothers. Ron was created first, then JK invented his brothers and sister. [Read the exact quote from Jo's website]
• Gideon and Fabian Prewett were indeed Molly’s brothers, but their history is not particularly significant in terms of the overall plot, except that their deaths do provide some explanation and excuse some of Mrs Weasley’s fears and her over protective stance towards Harry.

• Fred and George did not have foreknowledge of the Quidditch World Cup outcome; they simply gambled on a hunch and won. They “were prepared to risk everything.” [Read the entire quote from the Leaky Cauldron, 2005]
• Fred and George figured out how to use the Marauder’s Map because they were goofing around with it. The map helped them out too. [Read the entire quote from the Leaky Cauldron, 2005]
