Before, when Zoe had simply asked the question before herself, Davina had just been a bit annoyed with her. However, after performing the Protego Charm she was now more than just slightly annoyed. Why did she think that she could outsmart herself, Davina? Davina knew she was one of the cleverest in the year, if not the cleverest. She was more than the typical smart Ravenclaw. Her parents had been typical smart Ravenclaws and she was like their intelligence combined to be a genius. Most people thought she was big-headed for thinking she was clever. She didn't think she was though. It was just facts. Facts never lie. She had the best results in her previous years in Hogwarts. She knew it made a lot of people jealous of her, but she couldn't help it.
When other people answered questions before Davina, like this, it angered her to no end. She knew that she had to give the others a chance, but she thought that the teacher should have at least let her perform the demonstration, like before. She hadn't recieved any points for her answer or demonstration. She knew that Zoe would though. Probably because they felt sorry for the stupid little Hufflepuffs. Hufflepuff was like the reject house, she figured. Slytherins are cunning, Ravenclaws are clever, Gryffindors are brave but Hufflepuff just 'took the rest'* as the Sorting hat had once described.
