AN: Hogwarts!AU because I can. Also it's assignment time so I am more disposed to insanity but to be fair, this was the only way I could make this prompt work.
"Are you sure you should be doing this? I'm pretty sure there's other ways of practicing Transfiguration." Aaron said as he and Emily sat in the library surrounded by their homework. Aaron was working on his Defence Against the Dark Arts essay and Emily was reading over her notes on (of course) Transfiguration.
"Of course I am, besides I am top of the class for Transfiguration." Emily dismissed as she rummaged in her bag for her wand.
"I still say this will end badly." Aaron commented and Emily rolled her eyes.
"You really have so much faith in me Aaron. I'm touched." Emily said sarcastically as she looked at the book to check the spell before waving her wand. A loud bang and purple smoke burst out of her wand, prompting the other students and Madam Pince to glare at them.
"Nice one." Aaron coughed, waving his arm to clear the smoke before he saw Emily and pressed his fist to his mouth.
"What?" Emily asked self-consciously. "Have I something on my face?"
Aaron, not trusting himself to speak without laughing, pointed to the top of her head. Emily frowned and ran her hands up her hair. Hair. Hair. What the...? What were those?
"What is going on ov-?" Madam Pince asked, storming over to the Seventh Year and stopping short when she spotted Emily. "Miss Prentiss what have you done to yourself?"
"Um, spell backfire." Emily replied awkwardly as Aaron shoved their books, parchment, quills and inks back into their respective bags; having finally calmed down.
"We're going to go to Professor McGonagall now. Sorry about the noise." Aaron said politely to the still annoyed looking librarian as Emily pulled her cloak over her head and the two students quickly left the library, the other students staring at them as they passed. Once they were in the empty corridor, Emily took her cloak off her head and they hurried towards the stairs to go down to the Transfiguration department.
"So the best in the class are you?" Aaron joked and Emily glared at him. "You look like Sergio."
"And you look like someone who's going to be dumped if he's not careful." Emily retorted as she absent-mindedly began scratching her new cat ears. It felt strangely nice. Emily realised what she was doing and quickly stopped as Aaron smiled at her. He had to admit, Emily did look strangely cute with the dark cat ears.
Aaron put an arm around her shoulders as they came to the bottom of the stairs. "Come on, let's find Professor McGonagall."
