Perhaps you felt I was too harsh with you. But I knew what you were capable of and it was more than what you presented to me at the time. I asked you to tell me why you wanted to take my class. You never truly gave me an answer. The answer now sits in that vial." He pointed at the grey potion. "I know the answer was more than just removing a scar. You finally connected with what your intent truly was. Trust yourself, Miss Granger. Trust your intuition."
