"Helga Hufflepuff taught Herbology and she was also the secondary Healer at the school, the Matron being her younger sister Hetty Hufflepuff. Rowena Ravenclaw was the only one to teach an elective; she taught The Study of Ancient Runes. Godric Gryffindor taught two classes, Defence Against the Dark Arts which was curriculum and Duelling which was optional and only taught three times a week after the last class and before dinner. Salazar Slytherin was the Potion’s Professor, and he occasionally helped out in duelling, as he was a formidable opponent in his own right." Most of the class had wide eyes in shock, Justin was a shy boy by nature and very soft-spoken, to hear him speak so much and so confidently left them in awe, perhaps he had been underestimated.
