If Tobias didn't already stand as rigid as a statue, he was quite sure the look on the Slytherin Prefect's face would have turned him to stone.
"This is not negotiable Sterndale," warned Severus Snape, a man who extruded boredom and arrogance. A man who had been tasked with collecting Tobias from Azkaban, escorting him to Diagon Alley and then to Hogwarts. A man who was now his Head of House.
Watching the Prefect pack up the last of his belongings and vacate the singular dormitory in the Slytherin Dungeons was not something Tobias had wished to be present for, but it was a necessary evil.
Snape had told him that almost two hundred Howlers had been sent to the school, angry parents protesting that they didn't want their babies anywhere near Tobias Stonem, so a singular dormitory would be assigned to him. He knew his admittance to Hogwarts had been met with distain, hundreds of parents threatening to withdraw their precious angels from the school. Letters had filled a whole feature of Witch Weekly, a publication which had branded him a lunatic and a merciless killer while simultaneously running a feature on his brother winning another International Quidditch Association award. It was all rather pathetic. He hadn't realised that would mean a Prefect would lose his privileges, shame.

After Sterndale had vacated, Snape had nodded once at Tobias and drawled, "Your brother will collect you in the morning," before promptly leaving, as though he could not stand another second around Tobias.
He knew that Snape hadn't volunteered for the job of babysitter, he had told him so himself. The groundskeeper- who usually collected knew students had point blank refused, though Snape hadn't told him whether it was because he didn't want to go to Azkaban or he didn't want to be alone with Tobias.
With two steps of his long stride he entered the room and sat on the mattress. It was comfortable, but he knew it would be a waste. He stood again, before reaching over and closing the door. He changed quickly, and settled down on the bed- tossing the pillow onto the floor and placing his hands behind his head.

Tobias had not been able to sleep since leaving Azkaban. Strangely, he had grown used to sleeping on stone floors without sheets or feather pillows.
After three hours of staring at the ceiling, he moved his thin mattress to the floor and lay down on it, letting his eye-lids close over his silver flecked blue eyes, but it was to no avail and he didn't sleep at all that first night. He lay awake, unable to rest and unable to dream. Probably for the best, he reasoned, because his dreams often resulted in screams and furniture breaking.

Even after spending the day with Jason, touring the grounds and taking everything about his new home in the second night was no better. He had to enchant his bedroom so that the temperature was at freezing and a wind hissed through the small, singular dormitory in the Slytherin dungeons. Luckily, due to the Black Lake, the room was near pitch black anyway.
Even after scrapping his mattress and pillows altogether, and making the conditions of his room as close to those of his cell in Azkaban without bringing a Dementor in, Tobias could still not get a good night's rest.

He began to walk the corridors at night. Something which was strictly forbidden, but even the school caretaker and his ghastly cat didn't bother him.
"What do you think you're doing out of bed?" Argus Filch had hissed at him one night in the darkness.
"I'm just walking, I can't sleep," Tobias had replied, his voice lazy and sleep-deprived, "I won't leave the castle."
Tobias had brushed past him like he was a ghost, knowing there was nothing the man could do. Toby could smell magic a mile away and there was nothing about this man that was in the slightest way exceptional. After that he was sure that the Squib had gone straight to Dumbledore to protest, but at least he left him alone.

The only company Toby had in the early hours of the morning had been a poltergeist. He'd screamed his little head off at first, and early woken up the House Elves in the kitchen, but Toby had silenced him quickly without wand or words. The tiny ghost man was never any trouble to him after that, but sometimes followed him on his nightly walks, sometimes muttering things like, "You won't find anything to slaughter in there…." Or "Why so quiet Stonem? Dementors got your tongue?"
Hesitating once, in front of an eagle knocker on the west side of Hogwarts at the top of a spiral staircase, Peeves had warned Tobias that "You'll never get in there Stoney… Ravenclaw's are too smart for you." Realising it was the Ravenclaw Common room, Tobias had walked away and not returned. There was no knowledge in that Common room that was of any use to him anyway.

One night, Tobias had entered the library. The restricted section had peaked his interest and getting in was easy enough. There were enough books in there to keep him occupied for weeks. Access to so much information had made Tobias like an addict. The thirst for knowledge which he had been denied for practically all his young life could not be satisfied, and was all that kept him going during the daylight hours.
It even allowed him to tolerate the useless information the Professor's lectured him about in lessons, as if he didn't know how to produce a Vanishing Spell or brew a Forgetfulness Potion. Knowing that each evening he could escape to the library and delve into all the wizarding history and information he could ever wish for, that was what kept him from snapping Professor Sprout's neck and throwing her to her own patch of Chinese Chomping Cabbages.

The Stonem boy curled his body up into a large armchair by a window that over-looked the grounds, which he had to admit were outstandingly beautiful. He poured over an old copy The Art of Occulumency. The thin fingertips of the eldest Stonem played with the binding which was coming loose.
His interest had been peaked by a section of the book which mentioned how blocking one's mind to another's influence was invaluable. He recalled a branch of magic he had heard of once which enabled the witch or wizard who cast it to enter the body of another human being. He imagined the possibilities of being able to take over someone else's body, the things he could get away with and the needs he could sate that he would never be blamed for. His eyes fell closed, thoughts and the words on the page blurring as he fell into a deep sleep.

Still in the library, Tobias looked up from his chair, momentarily by a short Hufflepuff girl.
The girl was nervous, he could smell it on her. She knew who he was naturally. Whether he was more famous for being Jason Stonem's brother, or for being a psychotic murderer it was not really known, and not for Toby to say. The Hufflepuff practically ran past him on her way out of the library, stumbling on the way. As she got closer, he judged her to be fourteen, possibly fifteen, and fairly weak willed. He had no doubt that under the right conditions he would be able to take over her mind but before he could properly relish the thought of doing so and having her play around in her own blood- she was gone.

Footsteps echoed around the library, a recognisable stomp, and a tall woman strolled up to him. Pale skin, striking green eyes and a smile which could literally kill.
"Hello old friend," she stated, standing in front of him with her arms cross over her chest.

Looking up from under his long lashes, Tobias raised a perfectly sculpted eyebrow and shot her a tantalising grin.
A prominent figure from his past, through his teenage years, Tobias knew Felice Crowley as a fragment of his twisted imagination. Everything about Felice calmed him, and not for good reasons. Tobias was his most lethal self when he was calm and collected. When his brain was ticking over, dispelling bad thoughts and reminding him constantly that he was ill and trying to recover from a psychosis- that was when Tobias was most docile. It was when his brain cleared and he allowed the darkness to overwhelm him that things usually took a turn for the worst. Felice's natural aura was dark and deadly, and to Tobias it was like a drug.

The first time he had laid eyes on her he had been around thirteen years old, after he had first been admitted to St Mungos. She was a demon, and she had sat and spoken to him, calming him, convincing him that he was not ill- mentally or otherwise. He spoke about her sometimes to the nurses and Healers, but nobody believed him. She had been his invisible friend as a child, one who had encouraged him to do dangerous and deadly stunts, and to push his magic further.
She had been with him during his escape in his late teens, and together they had wreaked havoc all over the country for three glorious months.

Of course, some time in an Azkaban cell had taught him better. He had heard the whispers in the walls, some from other inmates who (when not overcome with fright from the Dementors) had told about the demon who could travel back and forth from her home in hell. Some whispers had come from Felice herself, reassuring him- comforting him.

"I suppose I forgot all about you," he smirked, his voice teasing as he looked her up and down. "Old friend indeed, perhaps if you had paid me a visit in Azkaban occasionally I might have remembered you."

Feigning a shocked and rather unimpressed look on her face, Felice mocked a loud gasp to his response and settled herself down on the arm of his chair, looking down at him with a small smirk before she reached to stroke a hand through his brown unkempt hair gently before resting it on the back of his neck. Her skin was cold, but Tobias was drawn to her. She had always been able to coax evil out him like a snake-charmer, and it was somewhat of an aphrodisiac for them both.
"Don't act like you didn't feel me in your cell with you. I was there," she murmured, causing the hairs to raise on the back of his neck. "I missed you terribly," she insisted, "before you were taken away we had such fun."

Her reminder of their time together committing crimes caused a coarse chuckle to fall from his lips. Everything about her intoxicated him, she had him hook, line and sinker and he couldn't really say he cared.
"Why are you here? What do you want?" he replied, leaning forward like a dog whose master had a treat.
Her grip suddenly tightened around the back of his neck which caused him to flinch in a way which was more pleasurable than painful, even more so when she sank down the armchair and into his lap.

Tobias was a complicated man to say the least, but around Felice he had never felt anything but normal. She had always been there for him, always appeared to patch him up when he'd fallen off the wagon, and to make him feel like what he deep down longed to do wasn't so horrible after all.
So when she moved to connect their lips in a passionate kiss it was the most natural thing that could happen in that moment. His hands reached up to cup her face and his lips moved hungrily against hers.

Moving in sync- as if they had been doing this for centuries together, she pulled his shirt open, running her hands along his chest as though she were ravenous and desperate for contact.
"I missed you," she whispered, her lips trailing kisses across his jaw and up to his ear lobe, "you're my favourite."
Every singular touch set his heart racing, her whispers caused a shiver to run down his spine and his hands dropped from her face, falling to her waist and pulling her impossibly closer.
He had always been obsessed with her, addicted to her presence, it was just the first time he had ever acted upon it, and now that he had started he had no idea how to stop.

"I'm here Tobias," she whispered again, and his grip tightened around her as he felt her being pulled away from him. "I'm here in the castle, come and find me."

Toby's eyes snapped open, he couldn't breathe and he tried to push himself up from the armchair he was slumped in but his arms were trembling with fear. Confusion flashed over his face, he was shaking? Pushing past the anxiety and paralysis, he blinked and ran a hand over his forehead. He was covered in sweat, his shirt drenched and sticking to his body.
The Occulumency book lay open on his lap as he had left it, and he couldn't help but feel like he was no longer alone in the library. His hands reached through his hair, pushing it away from his damp head and he stood up.
Taking deep, gasping breaths he stood, placed the book back where he had found it and practically ran back to the dungeons- all the while unable to shake the memory of Felice.
He never recalled his dreams, but this one was burned into his brain and he didn't know what to do with himself. He paced the length of his dorm thirteen times and then lay on the floor of his bedroom, breathing in and out slowly until the coldness left his body and he felt vaguely normal.
"I'm here Tobias. I'm here in the castle. Come and find me." The words churned over and over in his mind, and he couldn't help but entertain the impossible thought that Felice could be real.
