"Yes, you, who else am I pointing at Miss Deschain..." She said shaking her head. She turned back to the class and said, "I am going to teach you three healing charms." She said and then pulled her wand and aimed it at Astrid's ear.

"I've just given Miss Deschain an ear infection..." She looked at the girl and said "It's barely a little disconfort, I'll heal you soon enough." she smirked.

"Let's start by talking about infections. An infection happens when germs like bacteria and viruses get inside the body and cause trouble. Germs can get into your ears. Miss Deschain has a middle ear infection, that is when germs get into the middle ear and the area fills up with fluid or pus, which contains germ-fighting cells. When the pus builds up, your ear starts to feel like a balloon that is ready to pop, which can be uncomfortable." She said.

"The incantation is Auris, and the wand movement is simple." She said moving close to the girl. "You swirl clockwise twice around the ear then pull back." She demonstrated, healing the Gryffindor. "Any questions?"
