Severus Snape

Snape, a professor at Hogwarts. You had recently arrived at this school, and this was your first lesson with Snape. When the professor entered the room, all conversation died down and only the sound of his confident steps could be heard. You were lost in your thoughts and slightly flinched at the professor's icy voice. -Mr....! Snape called your name in a loud and stern voice and then continued -What happens if I add asphodel root powder to wormwood tincture? This question was intended to humiliate the student. His intense, arrogant gaze almost burned a hole through you. You couldn't answer the question and silently awaited Professor Snape's next barbed words.
