Marge Dursley Criticizes Harry's Parentage
Pages 25-26
Over lunch, Marge Dursley makes disparaging comments about Harry's parents, comparing them to dogs and suggesting that bad blood will out. Harry, barely managing to keep his temper in check, accidentally causes Marge Dursley's wine glass to explode. Although she brushes it off, Uncle Vernon and Petunia Dursley are suspicious of Harry's involvement.
