I think you fell into an online trap.
I COMPLETELY AGREE THOUGH.....
.....
the book says that dudley is a wizard too but her mom(aunt petunia) keeps him away from the wizarding world as she makes a deal with dumbledore when he asks her to keep harry potter
now in the seventh e-book i read syas that dudleys parents are terrified taht he is acting wierd just like harry did before going to hogwarts
the ending says ......
"'petunia dursely and vernon dursely were found dead at no. 4 privet drive
and there was a expresion of shock on there faces(that certainly means summon useda killing curse on them
and there son was never seen there again. a neibour was heard saying that he saw dudley dursely aroung the house on there death"
i mean i am sure this is loadsa rubbish but isntr it quite wierd ,,this is quite identical to the starting of the 4th book...u know when voldemort killed his father and all"""
wat do u guys this is it freally fake now
ps---before this wierd ending the epilouge also says that harry and ginny weasley get married and have a son named james potter and ya hermionie and ron get married tooo..................THIS IS VERY CONFUSING
BUT YA THE BOOK WAS VERYVERY VERY ROMANTICH
