Bertram Aubrey

Bertram Aubrey was a student at Hogwarts in from 1971-1975. During his fourth year, James Potter and Sirius Black caught Bertram attempting to rape Briar while she is unconscious, and use an illegal hex, Engorgio Skullus, to make his head swell twice it’s size. After dueling out detentions for James and Sirius, Dumbledore promptly expels Bertram and has him escorted off the grounds.
