The fact that Serafina was actually listening to his advice was both funny and curious. She seemed to dislike him, or at least find him to be a nuisance, so Jojo figured his opinion was very low on the totem pole for her. He chose not to remark on that, in case it got a sarcastic answer from her. The icy exterior she presented was seeming to melt a bit and Joseph didn't want her to set it back just yet.
"Hmm," Joseph said through grit teeth as he watched the swaying hips. He did not hide where his eyes were wandering this time. A nice womanly figure did very bad things to his brain and Serafina happened to be one of the most attractive girls at school. Too bad she was a stereotypical Slytherin girl, cold and unfriendly. He was determined to break that shell though.
Of course, she looked stunning in emerald. She always had and always would, but he could not deny that it had been quite nice to see her in other colors, "Stunning, as usual Sera. I'd say it's on par with the blue."
