In the middle of November, the incubus" energy started to wane. He still did not look as bad as before, but apparently, the lack of sex was getting to him. Ever since their meeting at the Astronomy tower, Zabini had refrained from entertaining lovers. He had, however, started to "court" Harry as aggressively as he could, without giving himself away to the entire school. Little treats, funny notes, all the menial trinkets teenagers favoured. Severus had observed stoically. He had kept his distance, during their "detentions'. Yet, he had stopped to single Zabini out. Harry considered it a win. However, the professor still ran interference when his snake tried to get to Harry alone. The teenager was unsure if the man was jealous or tried to save one boy from the other. Not that it mattered.
