Add the berries. That, he could do. How many, though? Olly peered up at the board so he would not get the number wrong. Eight, right, he should have remembered that. Everything was eight. That Sophie Brown girl was talking about something related to eight and arithmancy and infinity and whatever, but Olly was definitely not paying attention to her. Because he did not care. But he did add the eight berries, that was easy enough.

He grabbed his wand again and drew one large circle over the top of his cauldron clockwise. While he did so, he sprinkled alihotsy leaves onto the surface of the potion. What good did using his wand do without an incantion? Did it even do anything? He was too curious not to raise his hand. "Professor, why don't we have to say anything when we wave our wand? Or draw a circle?"

There was even more silent wand waving next. So Olly did. He waved his wand back and forth over the top of the cauldron. Why would that too anything? His potion did darken, but it looked more pink than red to him. Hopefully it was fine.
