To Professor Snape:

I beg you; please find a cure to this curse! I have been home for only two days and the Dursley's are seriously creeping me out! Dudley won't stop staring at me! I'm afraid he might do something. Please! I beg you!

Harry Potter

Severus leaned back in his chair as he contemplated the letter. It was quite disturbing that Harry would be afraid that her cousin would actually do something. But still, that would be highly unlikely. The b-girl was probably exaggerating to get attention.

He turned his attention then to the door. Someone was lurking outside of it. He took up his wand and carefully made his way to the door. The door opened with a bang and someone ran inside. Snape tackled the person to the floor, holding his wand to the person's head.

"Who are you! Who sent you!" Severus said as he turned the person over so he could look at them.

A gasp escaped his lips.

A woman with long, tan-colored hair, peppered with grey lay beneath him. She wore tattered robes that had been patched many times. Her mouth was clenched, her lips turning red from the pressure. But it was her eyes that caused him to gasp. Those honey colored eyes that held so much emotion.

"Lupin?" Severus asked quietly.

The woman beneath him let out a sigh. "Yes, Severus, it is me…" Lupin's voice had changed to an alto, and was silky smooth, not interrupted by cracks or the roughness that normally plagued his… her voice.

"You too?" Severus whispered under his breath.

"Me too? Who else has this happened to?" Lupin asked, her eyebrow's furrowing.

"Potter. Potter turned into a girl a couple of days ago. I think it fried her brains though. She thinks that her cousin is going to do something…"

"Will you please get off of me, Snape, you are quite heavy!" the tan-haired woman said, shoving the man off of her.

Snape got up and then walked over to his desk. Lupin followed him and cast her eyes over Severus' desk. She picked up the letter and read over it.

"I don't think that that is hi-her brain is being fried. I think that this is legitimate fear. Severus, how could you not report this to the Headmaster?" Her voice began to rise in volume, and Severus could tell that she was going into mother-wolf mode.

"I only just got the letter, Lupin." Severus muttered, crossing his arms and leaning back in his chair again.

"You are impossible!" Lupin said as she sat on the Potions Master's desk. "I am not moving until you go up to Dumbledore's office and tell him about the letter!"

Severus rolled his eyes and let his head fall back. He caught sight of the calendar and noticed the picture of the full moon on that day's date.

"Lupin…" Severus said, his eyes wide as he looked back at the woman on his desk.

"Yeah. I kind of noticed too, Severus. I've become a woman, and I don't change anymore. I came here hoping that you might know why."

"I have no clue." The obsidian-eyed man said as he got up, "But we are going to have a little chat with the Headmaster and try to sort all of this insanity up."

A/N: Yay! We have another person who changed gender! Though, I guess I should have a girl change too… any suggestions?
