"You see, Theo isn’t an only child. He’s the youngest of five, four elder sisters. All of whom Thoros rid himself of after the birth of each new heir. When Theo was born, he was thrilled because he finally had a son." Hermione was rendered speechless at the news. The most Theo had elaborated on in regard to his family was that his mother had been twenty or so years younger than his father. He’d never mentioned having a sister, much less four. It made Hermione question if he even knew of their existence, and sadly it was possible that he did not.
