Despite the love she felt for her younger sister, Lucy couldn't help but feel jealous. Clary was beautiful, she strongly resembled their mother, who was probably the most stunning woman she had ever seen. Clary was everything, whilst she was nothing. Clary had the ability to charm anyone instantly with her cheery personality, whilst on the other hand Lucy mainly scared people off. It wasn't as if she tried to unnerve them, it was just as if she saw the world differently, her observations often frightening away potential friends. She didn't try to be different, in fact it required almost all of her energy to suffer through the school system.

One, long ago, she had begged to be allowed to attend, and for the first few months she had never felt so… not happy exactly, intrigued would be a better word. Every new piece of information she learnt was welcome, instantly locking itself in her memory. Even just being around other children her age had been exciting, the way they thought interested her. However, Lucy quickly learned that for many people anything different was bad, and as soon as they noticed her peculiarities she was mercilessly teased.

Freak. Psycho. Robot.

And their favourite: Monster

Lucy had felt anger before, in fact it was more unusual for her not to be angry. But what she felt when they called her those names was unlike anything she had felt before. Anything her mother had taught her about holding in her anger and why hurting people was bad immediately fled her darkening mind. Suddenly, the idea of snapping their necks was rather appealing, and with every second the reasons against it were decreasing. Looking back, these thoughts should have frightened her, but it was how natural resorting to violence was that terrified her.

Two fractured arms, three cracked ribs and a concussion taught her tormentors not to mess with her. Unsurprisingly, Jocelyn instantly had her moved schools. Lucy found herself unbelievably irritated that she would no longer get to see those children and watch them flinch with fear whenever they saw her. Allowing them to suffer so little was nowhere near what they deserved.

Four teachers had to pull her off the broken bodies, and the spectators would later recall how the attacker was practically rabid in her defence, a wild dog focused only on her prey. They would also gossip, some remarking that Lucy's eyes had turned black, the white's vanishing in her bloodlust.

Jocelyn had picked up her phone and immediately dropped everything to rush to the school. Her worst nightmare had come true and she prayed to the Angel that no-one had been killed. She found herself in a classroom, her daughter had been isolated since the incident, even the teachers being too rattled to enter. She expected to see a demon in the guise of her 11 year old and thought through all the options in her head before she entered. The Shadowhunter in her knew that Lucy would never stop being a danger to those around her and it was her duty, not just to the mundane world, but also to whatever remained of Lucy's soul to put her down before all of her goodness was consumed. Yet she found herself unable to do that, she had chosen being a mother to her children over being a shadowhunter and had chosen to raise Lucy despite knowing the truth about her.

It was with this dilemma that she opened the door and braced herself.

"Mom? What are you doing here?" A young, child-like voice questioned.

Sitting at one of the tables was Lucy, her white-blonde hair recently cut shoulder-length and a smile on her face. But Jocelyn froze. The eyes. Lucy's eyes had always been black, a similar darkness to her ex-husband's, but it had been so long since they had been completely black, a sign of the demonic presence.

Not being able to help herself, Jocelyn approached the girl, coming to a stop a metre away. She could now see clearly the flecks of blood covering her blue top, her once white shoes now dark red.

"Lucy, are you in there?" She hesitantly, unsure in how to continue.

A worried look crossed the child's face, her brow furrowing as she stared at her mother. "Mommy, what's wrong?"

The voice wasn't her daughter's, Jocelyn knew that much. Lucy, or the thing inside her, spoke smoothly without compassion, unlike her normal voice.

"Do you feel any different right now? Are you angry? Remember I just want you to be happy." Jocelyn's priority was now to pacify Lucy's demonic blood, return her to the version of her that at least knew violence was bad.

Lucy's calm facade faltered, the white's of her eyes flickering between white and black. She opened her mouth, as if to speak yet the words struggled to come out.

"I don't know why I did it, really. I just feel so… free, it was like I just didn't care what was right or wrong."

Jocelyn cupped her daughter's face in her hands and knelt so that they were looking into each other's eyes. "Do you care now?"

"I…" Lucy hesitated, visibly conflicted. She was slightly shaking, as if forcing herself to think about it was uncomfortable.

"Darling, I need you to think about it. I've taught you how to be good, you are good. You may have bad thoughts sometimes but remember that it isn't the real you. The real you would never purposefully hurt someone. Can you focus on being good? For me, please try. I love you Lucy, but you have to do this."

Lucy nodded firmly, despite her reservations. Up until her mother had confronted her, her emotions had seemed so unnecessary, a burden that prevented her from being herself. However, something Jocelyn said caused the darkness to recede.

Jocelyn smiled as her eyes returned to normal and threw her arms around her daughter. She couldn't keep herself from bursting into tears, both happy with the knowledge that there was still a girl behind the demon, yet also sad considering it would likely not be the final time something like this would happen.

Whilst she may have helped Lucy, the situation was far from over. Jocelyn paid for any medical bills, the costs eating away the remnants of what she had taken before running from Valentine. She knew it was irresponsible but she couldn't remove Lucy from school entirely, instead keeping her at home for a few weeks before moving her to a different school.

As for Lucy, she knew that she had to change. Instead of being her true self, she pretended. Gone was the freak, and in her place was a charming, funny and polite girl that had many friends who were ignorant to the truth that it was all a lie.
