NEW YORK, June 24 — JK Rowling yesterday once again served up some details to appease her fans by revealing background information about the mean and nasty Vernon and Petunia Dursley.

Rowling’s fansite Pottermore also unveiled yesterday new, interactive sections of “Deathly Hallows”, the final Potter book in the series.

With a surname derived from a town not far from where Rowling grew up, the Dursleys met at work, where Petunia quickly became smitten by the “deliciously normal” Vernon, according to the exclusive content published on Pottermore.

Rowling revealed that Petunia was scared to confess to Vernon that her sister, Lily, was a witch attending Hogwarts School of Witchcraft and Wizardry. A shocked Vernon said he did not hold it against Petunia, but he despised both Lily and her then-boyfriend, James Potter, by the end of their first meeting, where he learned about flying broomsticks and Gringotts bank.

The Dursleys did not hear from the Potters after they received Harry’s birth announcement, which Petunia threw away. Petunia raised Harry “grudgingly” and Vernon’s distaste for James Potter contributed to his opinion of Harry.

Perhaps the biggest revelation in her new text is that Rowling wanted to see a nicer side of Aunt Petunia “when she said goodbye to Harry for the last time.” But she stuck to the true nature of Petunia’s character, having her “behave in a way that is most consistent with her thoughts and feelings throughout the previous seven books.”
