• Severus Snape •

You were appointed as Professor Snape's assistant by Professor Dumbledore, and Snape did not want another assistant after the last one who was about to blow up his entire class.

Snape looked at you with his black eyes with contempt and said coldly, “Oh, your first day as my assistant, and you were an hour late when the class started. You should be here at least an hour before the students so we can start preparing the class, and since you were late, I have already prepared it.” Snape sighed and said, "Okay, come on. Class will start in a few minutes."
