Narcissa took her wand from her bag and tapped it against her lip, watching as Dominic gave his own a swish. She smiled, approving of his ability. He was a brilliant wizard and she was interested to see how his future would progress. He would not be a bad husband, she found herself thinking. He is not an old bloke, he is talented, and his bloodline is pure. She didn't know if she would hold much sway over her parents when they made the decision of who she should marry when it came time, but Dominic would not be a terrible choice.
She was loath to admit, but not so talented with spells to be able to protect their space with a nonverbal. She gave her wand a wave, whispering "Cave Inimicum".
"Perhaps a bit strong for our purpose tonight, but I suppose that will do the trick," she said. She took a seat at the table, glancing at Dominic. "You would not think less of me if I took my sweater off? It's rather stuffy in here and I came straight for class without changing." It didn't seem proper for her to undress in front of him, whether it just be the top layer or not. Still, he was a close friend and she wasn't doing anything inappropriate. Merlin knew she had shown a little more back here with other boys.
