"No" she said. "The counter potion is for accidents." She said coldly.
"Look, Crocker," thankfully you needed a translator to fully understand the boy, and she did not catch that he's called her a house elf. "Let ME enlighten YOU. The correct form of addressing a young boy is 'Master.' You know what... Nevermind. Get back to your potion." She said shaking her head.
"Don't be sorry, you are doing fine." She said.
Was she serious? Had she not been in this class?
Nevermind. Continue with this class... she thought to herself.
She glared at the girl. She took 100 points from Slytherin for disrespect, she wasn't above taking the same from gryffindor.
She smiled at the boy as he smashed the leech. Typical boy.
The color wasn't right. "You forgot the knotgrass, Miss Page." She said, "Thank you, now I can show how to fix this." and she took some more goat's milk. "Soak the knotgrass in the cold goat's milk for 2 minutes and then you can add it before the next step." She said and then addressed the class. "There aren't many potions or many ingredients that you can fix after the time to add them... this is one of the few. The knotgrass is coated, we aren't that far into the potion, and the cold goat's milk will help re-process everything." She turned to the girl and said "Do that and then the next step."
She summoned the next ingredient and placed it in her clean mortar. "Crush the bicorn horn, withdraw a tbs and add place it in a spoon. Come to me with the spoon and I will drop a phoenix tear on it, then go back to your cauldron and stir them in 15 times clockwise." She said and demonstrated.
