"Why? Why? I’ll tell you why. Ramses Malfoy had at least two sons. Stefanus, the son who wasn’t magical, was thrown away like broken eggshells. Any man who would do this to his own son is no superior human, even when he can make a feather float! So Stefanus was cast out, because Ramses refused to act like a father, then generations passed. Three generations after Stefanus, Hermione was born and she could do magic, to her complete surprise; four generations after Stefanus was born, Penny and Felix were born, who could do magic without knowing why. Thanks to Ramses Malfoy being a Pureblood pillock, Hermione, Penny and Felix hold no loyalty to the Malfoy family, so neither will I."
