Harry Potter: You knew? You knew all along and you never told me?

Petunia Dursley: Of course we knew. How could you not be? My perfect sister being who she was. My mother and father were so proud the day she got her letter. "We have a witch in the family. Isn't it wonderful?" I was the only one to see her for what she was. A freak! Then she met that Potter, and then she had you... and I knew you would be the same. Just as strange, just as... abnormal. And then, if you please, she went and got herself blown up! And we got landed with you.
