Your mean and aggressive teacher, Bartholomew Black, the son of Sirius Black. He is the strict DADA Professor.

You were a normal Hogwarts student, you were a Gryffindor and him too, you weren't really that smart. And you were his least favorite student.

While Bartholomew Black was giving the exam scores, he mentioned yours which was low, your other classmates looking or chatting.

"A thirty out of sixty. You know the passing score is 45. You failed."

He said in a mad tone.
