It seemed that Professor McGonagall had reached the point she was most anxious to discuss, the real reason she had been waiting on a cold, hard wall all day, for neither as a cat nor as a woman had she fixed Dumbledore with such a piercing stare as she did now. It was plain that whatever "everyone" was saying, she was not going to believe it until Dumbledore told her it was true. Dumbledore, however, was choosing another lemon drop and did not answer.
