16 years ago Jocelyn would have never thought that she could love her daughters equally. She had believed that the fear and dread directed towards her eldest would ever fade-to her mistake. Some time Lucy's first word "mama" Jocelyn had realised that despite the demon blood coursing through the infant's veins she was still her child, not Valentine's, never Valentine's. It was only down to luck that Lucy had not perished with her father and brother. Looking back she hated herself for even considering killing her baby, the idea of raising a monster seemed to painful, and it was only upon realising she was pregnant again that she decided to keep her.

Initially she had been terrified that Lucy wouldn't remotely resemble a normal child, the signs already present. She had never cried, not once, preferring to stare with those unfathomably black eyes that contrasting so greatly with her white-blonde hair. It was with these fears that she had gone to Magnus Bane, desperate for a way to reverse, or even halt the effects of the demon blood. Unfortunately he deemed it irreversible, the demon blood was a part of Lucy now, however her humanity hadn't been burnt away completely, to Jocelyn's surprise. Some of her soul, no matter how small, was clinging on, refusing to let the demon take over. As such, through weeks of effort, Magnus was able to create an amulet capable of keeping the demon from consuming what remained of the soul. Jocelyn had been overjoyed, thrilled at the idea of there being something of her daughter left, though the amulet came with warnings and consequences. It must never be removed from around Lucy's neck or else the demon blood would swarm the remnants of the soul that it had been denied. However, ensuring that the baby remained with it proved much harder than she initially assumed, added to by the stress of her advancing pregnancy. It was only with Luke's help that she was able to manage those first few months after Clary had been born.

Though Clary's infancy only highlighted the differences between the siblings, surprisingly Lucy was eager in her role as an older sister, often refusing to leave her side. Her affection tended to border on possessive however Jocelyn was keen to raise Lucy with the morals that her nature lacked. As a small child Lucy often alternated between two, highly conflicting personalities. One was the mischievous, happy, loving girl that often succeeded in making Jocelyn forget Lucy's true nature, the other was a side that succeeded in terrifying her constantly. Though it happened less as she grew older, Lucy would sometimes snap, her eyes cold, her fists clenched, and it was this version of her that Jocelyn knew wouldn't hesitate to hurt those around her.

For the most part Lucy seemed unaware of her mental instabilities, thinking herself an ordinary child, especially for the first few years when Clary was too young for her to compare herself with and considering Jocelyn was reluctant to let her play with other children. However, once she reached the age when other children would begin school, Jocelyn was hesitant, prompting questions that she was afraid to answer.

"Why is Clary going to school but I can't?" Because I'm afraid someone will get hurt… The unspoken 'by you' stayed in Jocelyn's thoughts.

Luckily Lucy seemed unaware as to her own capabilities, her arguments rarely resulted in physical confrontations. At least until her turned 10. Clary was having her 8th Birthday party and a dozen friends had been invited to the Frey household. Despite having a good relationship with her sister Lucy found herself becoming jealous of the ease with which Clary made friends and was liked. With no friends of her own, Clary was all that Lucy had and until then the threat to their relationship hadn't been visible. An anger rose in Lucy like she had never felt before, to the extent that it felt like her blood was boiling, any restraint or self-control that Jocelyn had try to install in her vanished immediately. Distracted by the task of readying the cake Jocelyn failed to see her daughter walk over to the group of younger children and focus her attentions on one girl in particular who was presently holding hands with Clary.

Without a second thought Lucy grabbed the girl's arm and snapped it in two as if it was nothing, ignoring the resulting cries of agony. The screams were inconsequential to her, a sign of weakness, she had been taking Clary's attention and deserved to be punished.

It was as if Jocelyn's worst fears had emerged, all her efforts to raise her daughter to be more than what her nature dictated had been for nothing. Acting on instinct she grabbed the small white-blonde girl and pulled her away from the chaos, locking her in her bedroom before attending to the injury. It was fair to say the party was over and Jocelyn had followed the hurt child to the hospital, asking Luke to supervise her daughters. Upon returning to the home hours later she learnt that whilst Clary had spent the entire time crying, Lucy had yet to emerge from her room.

Carefully Jocelyn opened the bedroom door, spotting the 10 year old reading peacefully on her bed. Kicking her legs back and forth she seemed oblivious to the damage she had caused and had reverted back to the innocent personality that her mother had fallen in love with.

"Lucy…"

"Hi mommy." The reply was carefree and naive.

Unsure of how to continue Jocelyn sat beside her daughter, pulling her into her arms protectively. A small part of her knew that it was ironic, it is the world who should be protected from Lucy but her maternal instincts overrode that notion.

"Darling, why did you do it?"

"Do what?" Her nose scrunched in confusion, closing her book. Sitting there Jocelyn couldn't help but see Valentine in her features, the same hair and dark eyes made black from the demon blood. Yet the malevolent feelings she felt towards her as an infant had faded and Lucy was now simply her daughter, not Valentine's experiment, not tainted by demon blood.

"You hurt Emily, Clary's friend. I just want to know why?"

"Oh!" Lucy seemed to realise what her mother was referring to. "I don't know really, I was just really upset. Clary is my friend not theirs."

"Why can't she be both? Think about how lonely Clary would be at school without any friends, do you want her upset?"

This prospect seemed to terrify Lucy, who shook her head vigorously. "I don't want her to be upset, I would do anything to make her happy."

Jocelyn tucked a strand of her daughter's hair behind her hair. "Hurting your sister's friends makes her upset and-"

"Her arm will heal, and she deserved it." Lucy seemed to earnestly believe, unable to comprehend why hurting people was bad.

"Lucy… dear…. you can't just hurt someone who makes you upset. You have to learn, otherwise you won't make any friends."

"But mom, let me go to school so I can learn how to make friends. Clary gets to go to school everyday and play with other children and make friends but I have to stay here."

"Don't you like me home-schooling you?" Jocelyn half-teased.

Jocelyn had never seen the resulting look on her daughters face, desperation. The almost angelic-looking child couldn't seem more different to the thing who had snapped that girl's arm.

Giving it, Lucy was enrolled in school the next week and attended without major incident until she was 18, still ignorant to the truth of not only her father and mother's past but also her existence.
