Mandy was hardly immune to the insults and she felt quite... well, small, really. Glancing between Oliver and his mother, she managed to keep the hurt off her face and refrain from apologizing. It was clear that Catherin Wood wasn't going to be interested in anything Mandy said or did to attempt to put them on equal footing. In fact, if she didn't know better, she'd say the woman was purposely hating on her and Mandy couldn't really fathom why.
"I, ah, am an experimental Potions Master with the Ministry of Magic," she said, a note of pride in her voice. She was exceptional at her job and one of the youngest in her field and one of the few females. "I work in research and development." Mandy was an excellent chemist and her time spent among the muggles had really helped with how far she'd come in her field.
