Professor Severus Snape glared as he patrolled the halls of Hogwarts. He had already sent a dozen students on their way all with a detention and points deducted from their houses. It was only when a scream sounded did he stop. He turned the corridor and hurried along. A second scream led him into the girls' bathroom on the second floor. Lying on the floor was a young ravenclaw, a hufflepuff girl kneeling next to her.

"Professor I don't know what happened. I came to get her before curfew as she had been throwing up. We were just about to leave for our houses when she collapsed and started screaming."

Severus looked between the frightened girl and the other girl now withering in pain on the floor. This was slightly out of his field of expertise has it wasn't something he had come across in the seven years he had been teaching for.

"What's your name?" He questioned.

"Nymphadora Tonks and that's Siena Miller sir."

"Right Miss Tonks go get the Headmaster and tell him to meet us at the infirmary."

"Yes sir."

Severus couldn't tell but she seemed relieved that someone was taking charge as she had looked as if she herself was about to collapse in fear. He waited until she had left the room before he turned his attention back to Siena. He held her head still as he locked his eyes with her to perform Leglimency.

Severus found himself in an open field with no distinguishing features except for the girl that was tied to wooden post like a scarecrow. He recognized the girl immediately, it was the same one he was with back at Hogwarts. As he made his way over to the other end he saw someone in a cloak with the hood covering their face lash out and hit Siena with a whip, then stab her. Severus quickly hurried over to them and stood in front of Siena.

"That is quite enough. Leave this girl alone. She is under the protection of Hogwarts," Severus told the man.

"She's nothing but a filthy half breed. Her muggle mother left her on my door step as I'm her father so she's my property."

Severus turned to face Siena and pulled back out of her mind making sure to bring her with him. He took in a deep breath to steady himself as Siena let out another scream before going limp. He could only hope that her father would stay away for a little while longer.

"Severus what is it?" Dumbledore questioned.

Severus looked around and noticed that both Nymphadora and Dumbledore were watching him. He quickly made his face appear impassive as Dumbledore placed his hand on Severus's shoulder.

"Five points to hufflepuff's Miss Tonks for being a true friend and not deserting a friend in such time of need. Thirty points to Miss Miller here for surviving trials past her years with great skill and a determination not to be defeated," Severus told the pair.

Severus scooped Siena up in his arm and made his way up to the infirmary. He looked down at the girl in his arms as he finally recognized her. She was a fifth year and in his potions class, a very quite student she seemed to slip below the radar but always got good marks and had yet to turn a potion into a disaster. She was light to hold he realized, far to light than anyone should be. When he reached the infirmary he laid her down on a bed in the far corner away from the one other patient in the room that Madam Pomfrey was currently treating.

"I will be back shortly Miss Miller, in the meantime try to stay awake," He told her.

She gave him a small nod and a smile. He could see that she was still in some pain. He made his way out of the room and down to his dungeons. While he would never admit it to anyone he had a soft spot for other people who had suffered abuse like himself. As he hurried along the corridors his mind started making a list of the ingredients he would need.

When he reached the door to his office he swung the door open with a swish of his wand quickly removing the wards he had in place. He immediately went straight to the storage cupboard and opened the door. He used his wand to get all the ingredients he would need, they flew out one by one and lined up on a table. As soon as that task was done he set about preparing the potion. He had only just started stirring when Dumbledore walked in.

"Ahh Severus I thought I would find you here. What are you brewing to my boy?"

"It's a potion sir that until I know more about the situation and can adequately make a personalized version this will protect Miss Miller against her father invading her mind again. She will need to take it every day. He does not use Leglimency but something a lot stronger and of the ancient magic."

Dumbledore gave a nod in understanding, this did put them in a difficult situation as to what they could do for Siena. Dumbledore quietly left Severus to his potion. When he was finished Severus put it in several vials before hurrying up to the infirmary again. He headed straight to Siena's side and found her asleep.

"Why is she sleeping?" He asked.

"I told her to rest Severus."

Severus glared at Madam Pomfrey but before he could say anything Siena started twisting and turning as she let out a scream. He gripped her by the shoulders and lightly shook her awake. When she opened her eyes she stumbled off the bed and over to the other side of the room, fear written all over her face.

Severus and Madam Pomfrey watched as Siena shoved the sleeve of her shirt up and pressed a knife she had pulled from her pocket to her skin. Severus strode across the room and knelt down in front of her. He noticed that her whole arm was covered in cuts and scars. He placed his hand on her's that was gripping the knife so hard her knuckles were white.

"Siena look at me," He softly commanded.
