Chapter One: The Problem

"What could be causing this?" Professor McGonagall asked in exasperation. Professor Flitwick finished assigning detentions to the three sixth years that had been fighting in the corridor, and sent two of them to the infirmary.

"I don't know Minerva," he said. It was the third fight they had broken up that week, and it was only Tuesday. They both sighed, and then McGonagall glanced at her watch.

"We're late for the staff meeting," she announced, and began striding towards the staff room they had been heading to before the brawl in the hallway interrupted them. Flitwick had to run to keep up, and was rather out of breath when he reached the room just behind her. (And what a nice behind she had) Flitwick blushed and took his seat. Glancing around to distract himself from this thought, he saw he wasn't the last teacher there, in spite of being ten minuets late. Dumbledore smiled a distracted welcome, while professor Trelawney ignored their arrival and continued to speak in rather different tones then here usual mournful whisper.

"I can sense a dark force hovering over Hogwarts! You must put a stop to this!"

"What's upset her so much?" Flitwick whispered to Professor Sprout.

"Crab and Goyle had a scuffle in her parlor this morning and broke most of her teacups." She responded tiredly. Just then the door was thrown open and Professor Snape stalked in. His threatening aura was marred by two scratches on his left jaw, and one of his sleeves was hanging where it had been ripped nearly off at the shoulder seam. He glared at the assembled teachers as he took his seat, daring any of them to comment at his condition, and wiped a drop of blood off his face with a handkerchief.

Dumbledore stood up, interrupting Trelawney's tirade. "Now that we're all here, does anyone have any new information to report?"

"I checked the entire school for a charm that could cause this aggression and found nothing." Flitwick said wearily.

"And I haven't found any curses other then an impotence curse in the seventh year bedroom for male slytherins," said Bill Weasley, who had accepted the position of DADA professor for one year. "You might talk to Miss Parkenson about that Severus." He smiled at the glowering head of slytherin.

Professor Snape growled. Starting more then three weeks previously, the number of student conflicts had begun to rise. Previously stable relationships fell apart and reformed in new patterns. At first the teachers had called it spring fever and put it down to nerves about Voldemort, but soon it was clear some outside influence was at work. Severus was disgusted with by the fact that the slytherins had been in more fights then any other house since the start of the strange behavior. He did his best to control the students during potions classes, but it seemed he had more trouble than the other teachers.

Hagrid broke into the tense pause, "this doesna' seem like something HE would do. I mean, it's not doin' much harm, really."

"No Harm!" Trelawney would have continued if Dumbledore hadn't given her a warning look.

Bill looked thoughtful. "When you look at each individual incident it seems like a simple case of excess hormones. Maybe something is giving everyone extra sexual energy, and some of it is being expressed though violence due to the students immaturity."

"Yeah, I know I've been feelin' kinda frisky lately, haven't you?" Hagrid asked innocently. There was silence as they all avoided each others eyes.

Finally Snape broke the silence. "I think Hagrid is correct in that Voldemort is probably not directly involved in this. While there have been a lot of fighting among the students, the majority of them are behaving as well as they ever do. Nor has anyone been seriously injured."

Dumbledore sighed. "I take it you have all searched for the cause of this disturbance to the best of your abilities. Has anyone found anything that might relate to it? No? Well in that case we might as well get ready for supper. I know you will all continue to think on the problem. If anyone has a new idea, don't hesitate to bring it to my attention, no matter how unlikely it seems."
