Author's Note: I do apologize for the very, very long wait. Real life seemed to have caught up with me for a while. This is a sequel to Truth & Measure and immediately picks up where the last chapter finished. I've changed some of the plot to fit my story. This story does include femslash, so if it does offend you, I apologize in advance.

his is told from several POVs so I hope it doesn't confuse you too much. This chapter has been beta-ed by Violent-Flames. Thank you so much for being my beta and taking the time. Reviews would be greatly appreciated.

Chaos Theory

Chapter One:

Chaos Theory:

The branch of mathematics that deals with complex systems whose behavior is highly sensitive to slight changes in conditions, so that small alterations can give rise to strikingly great consequences.

Fangs pierced the soft, smooth skin. The body beneath her writhed in pain and a soft choked gasp escaped pale lips. The smell of sweat and blood hung heavy in the air as the human body beneath her arched and hands grasped at her shoulders. Amelia tried not to moan in pleasure as she savoured the strong, hot blood as it pumped into her mouth and down her throat. It had been a long time since she had tasted fresh blood. She continued to swallow greedily, until Trinity's grip around her became weaker, her heartbeat slower. Pulling back slightly she licked her lips and peered down at the pale young woman, taking in her heavy, slow breathing and blood soaked shirt.

Trinity's eyes were half closed. Her vision blurred and she could barely make out the dark red of her own blood, covering Amelia's lips above hers. Trinity's eyelids suddenly felt too heavy to remain open and slid shut as the cold and the darkness crept in, surrounding and then engulfing her. It dragged her down into an endless pit of blackness, weighing her down until she couldn't breathe. In the distance she could voices whispering her name and she struggled to reach out, trying to pull herself from the infinite abyss she was being dragged into.

A bright light immersed her and a cry of surprise escaped as she was sucked in. Blinking several times, her blue eyes darted around the familiar looking run down lab and a sense of apprehension and bewilderment flooded her.

"Hello?" Trinity called out softly as her ears picked up the melodious symphony of Beethoven. Hesitating, she glanced around her lab before slowly moving towards the source of music. Stepping past her workstation, blue eyes landed on a familiar figure standing by her favorite plant. "Gabe?"

The black man turned around and a smile was touching his lips. The blonde felt her breath catch at the sight. A magnificent smile graced her features as she rushed forward and wrapped him in a tight hug, unable to believe that he was here before her, in her very arms. "Trinity," Gabe breathed, closing his eyes as his best friend drew him in for a tight hug.

He couldn't help but chuckle as Trinity stepped back and slugged him in the arm, and watched somewhat amusingly as the blonde clutched her "injured" hand. Rubbing his arm, he looked at her. "I guess I deserved that."

"Deserved that? You deserve more that…You left! You left us! You left me!" Trinity replied angrily, her finger pushing against his chest as each word left her mouth.

"I'm sorry."

"You promised you wouldn't leave," she said lowering her voice as she stared up into those familiar brown eyes and Gabe could see the blonde's heart breaking right in front of him.

"I know. I never wanted to go-"

"But you did, you left…" Trinity said, stepping away from him as tears threatened to spill. Suddenly she felt anger and resentment, blaming Gabe for not fighting hard enough. For not fighting to stay with them, with her. She had lost everyone she had ever loved.

"I was so mad w-when you left…It hurt so badly," the blonde sobbed and Gabe drew her in, hugging her tightly, feeling his own tears threatening to fall. The pent up hurt and anger pushed through like a dam breaking, and Trinity sobbed. Her heart ached at the loss.

"I never left Trinity," the black man softly assured and reached out to comfort his best friend, wiping away the fallen tears, "I'll always be here, watching you. Nothing will ever change that."

The blonde sniffed and wiped away a few stray tears, her brows creasing as she pulled away from him, confusion suddenly spreading across her face. "W-Where am I? The lab was destroyed during the attack…"

"What's the last thing you remember?"

"I was…at the mansion…I remember gunshots and then…the garage and…something attacked us…Amelia," Trinity drifted off with a faraway look in her eyes and Gabe waited patiently for her mind to catch up. "Amelia…she…"

"She's given you the choice of life instead of death. Here, where we are…this is just the in between. Time does not matter here," Gabriel looked around and smiled somewhat sadly at her. "The only thing that matters is you."

"What's going to happen to me?"

"That's up to you."

"What if I don't come out of it? What if I don't wake up?" Blue eyes widened in fear. She knew even in the haze of it all that there was a chance that she wouldn't be able to sustain the virus.

"You say that as if you don't have a choice. You can choose to fight… to beat the odds…it's up to you," Gabe said, reaching out and squeezing her hand, trying to give her the courage she so desperately wanted.

"Can I stay here, with you?" Trinity longingly asked, not wanting to leave the comfort of the place around her.

"That's a choice too. But you have a life that's waiting for you, there are people who love you and depend on you. Your time's not up yet Trin," Gabe softly answered pressing a lingering kiss on her head. "You can't stay here and deep down you know that."

"I-I don't want to leave you," the blonde replied ducking her head and swallowing thickly as she tried to hold back the sob that threatened to escape. Gentle fingers reached out and tilted her head back up to meet caring brown orbs.

"It's okay Trinity. I'll still be here waiting for you, I promise, you will see me again when it's time."

Though I cannot predict the future, the consequences of tonight will reverberate through the halls f both great covens for many years to come. One vampire elder has been slain by my own hand. Soon Marcus will take the throne. And a tide of anger and retribution will spill out into the night. Differences will be set aside. Allegiances will be made and soon, I will become the hunted.

The distant sounds of gunfire could still be heard as the bedraggled group made their way through the underground tunnels. Sharp grey eyes focused ahead, flickering back and forth through the shadows, waiting to catch sight of any enemies. Jonathan spared a glance over his shoulder at the others, taking in the wounded and worn looks of his team. And yet, as he looked at each of them, he couldn't help but see a small spark of hope and victory shining in their eyes. It had been a long night, a night filled with loss and death for all of them. Both sides would be counting their losses and Jonathan knew that there was more danger ahead now that both Viktor and Lucian had been slain.

Jonathan's gaze shifted and this time it focused on the back of the vampire ahead of him. She had slain her Sire, the man whom she looked up to as a father, and a man she loved like her father. The betrayal had cut deeply, and yet as she stood over Viktor's body, Jonathan saw the weight of the world lift from her shoulders if only for a moment, before the reality of her actions hit her. He could see the warring emotions – the fear, the anger and hope staring back at him as he gazed into dark orbs. Selene had risked everything to get Michael back safely, risked everything to keep them safe. She had ultimately chosen her side and there was no turning back… for any of them.

"They're leaving us alone," Michael murmured as he looked around the tunnels uneasily.

He had expected to be met with some resistance from the lycans and vampires, yet so far they had been left relatively alone. Flexing his fingers, Michael couldn't help but feel the enormous amounts of power that was now coursing through his body nor could he forget the painful way his body had transformed after being bitten by Selene. He didn't understand what was happening to him, but what he did know was that he was no longer human. He was aware of everything around him, he could see the tiniest details that he knew he shouldn't be able to see or hear or smell. Whatever he was, Michael knew that he was now in more danger than he was before.

Glancing around the dark tunnels, his eyes gravitated towards the vampire, and couldn't help but feel a strange pull towards her. He had felt the exact same pull after Lucian had bitten him. Frustration mounted inside him as he struggled to piece together the bits of information, trying to understand the strange world around him.

A gently, calming hand touched his arm, causing him to tear his gaze away from Selene and he found himself staring into concerned yet anxious hazel eyes. Melinda. A sense of guilt hit him at the thought dragging her in a world filled with uncertainty and violence. Yet as he stared into her eyes, he could see the love shining through. It wrapped around him and filling him with warmth - the familiarity of it grounded him.

"The lycans are…for now," Leo replied, green eyes flickering across to the Death Dealer. The elephant in the room was now becoming more and more obvious and Leo knew that someone had to ask the question. "What are the chances we'll make it to the mansion without any trouble?"

Selene spared a glance over her shoulder and for the first time Leo saw a glimmer of human emotion. Dark eyes shone with uncertainty, that very same question had been plaguing her own mind, "I don't know. Amelia had promised safe passage, but with…Viktor's death that may change. You won't be the only ones the Death Dealers will be hunting tonight."

"Alright, let's keep moving. The quicker we get out of here, the quicker we get to Ordoghaz. We grab Trinity and get the hell out of there," Jonathan instructed, not wanting to stay down in the tunnels for longer than necessary.

If Viktor had turned on them as he had suspected and without Amelia's knowledge, then he knew that the remaining Death Dealers were now acting on the fallen elder. They were now going to be targeted, and with the Lycans likely looking for revenge, Jonathan knew that they were now stuck in the middle. Moving forward, Jonathan led the group down the tunnel, intent to put some distance between the war and his team.

"Is this the exit?" Jamie asked looking up at the ladder critically and then down at his injured leg.

"Danny, Leo scout ahead, I want to make sure we're not running into trouble," Jonathan ordered and the two quickly began climbing up the ladder.

It didn't take long before Danny peered down at them, giving them the all clear. The tunnel and ladder had led them to exit in the middle of the city in the dead of night. Selene knew that it would take another twenty minutes, if they were lucky enough, to reach the mansion. Breathing in the fresh air, dark eyes roamed the empty streets as she tried to slow the thoughts in her mind.

For six centuries she had been nothing but a loyal soldier of the vampire clan, and in one night everything she had known about the world around her was shattered. In one night, she had uncovered the lies and secrets of a man whom she loved as a father. The vampires being united by a lie and then the secret alliance between Kraven and Lucian now threatened to destroy two great covens. And with Viktor's death, by her own hand, Selene knew that her allegiance had shifted to a group of renegade soldiers and Michael, a descendent of Corvinus. He was neither vampire nor lycan but a hybrid and she knew that it was only a matter of time before Amelia and the remaining council knew every detail of the confrontation in the tunnels.

Time is against her and as the last of the group climbed out, Selene was already making her way across to the closest vehicle. There was no telling what Kraven would do. He was a man with nothing left to lose but everything to gain. But he was not the only thing she was concerned about. There was still Jonathan and his team, in particular both Michael and Trinity - the latter weighing heavily on her mind. Without hesitating, Selene drew her weapon and fired at the passenger window.

"Jesus, are you trying to draw attention?" Jamie hissed glaring at the vampire before his eyes darted around the dark empty streets of the city. After the night they had endured, his nerves were more than frayed.

Ignoring him, Selene reached in and unlocked the door before pulling it open and climbing into the driver's seat, already working on hot-wiring the vehicle. "We don't have time to sit around."

"Well, we're not all going to fit in that," Danny murmured as he stared at the red sedan sceptically.

Jasper paced back and forth on the clean, polished floors of the Ziodex research facility, one of the many branches located around the world. It was the official and legitimate business front of the coven, producing cloned blood to sustain their existence and weapons for that same purpose. It was one of the advanced bioengineering research companies in the world. The events of the past two nights replayed over and over in his mind as he paced back and forth. The loss of his brother was still fresh in his mind and retribution burned deeply in his soul, as he wished he were out there searching for the man responsible for his death.

And yet, as he paced, his mind drifted to the unconscious blonde human who had not only captured the attention of his Elder but also a certain Death Dealer. During that short time, Jasper had grown to trust Trinity, and the more he thought about it, the more he came to realize that there was a small part of him that was rather fond of her. She was different from the others and that fact had been evident when she worked tirelessly to revive Amelia back to full strength.

The betrayal of Kraven had left the coven buckling at its knees, leaving it vulnerable to any attack and, that much was proven by the winged beast at the mansion. Anxiety and fear began to eat away at him as the night wore on. Selene was going to kill him with her bare hands when she discovered that Trinity had been critically injured and on the verge of death, only to have Amelia bite her. Jasper didn't even want to think about what Jamie and the others would do once the news reached their ears. He had been in charge of keeping her safe and he had failed. The guilt crept in and a sudden helplessness crawled up at him. If he couldn't even look after Trinity, how was he ever going be a Death Dealer?

"This is not good," Jasper muttered, running a hand through his hair, "This is not good."

The frantic drive to the research facility was all but a blur to the young vampire. Adam had made the decision on the destination, knowing that the safe houses didn't have the proper equipment to deal with Trinity and her injury nor the security he needed to make sure that they were safe until reinforcements arrived. Having more than a dozen armed men patrolling the perimeters had at least eased part of his worries. As a precaution, Adam had ordered to have security patrolling every floor, wanting to make sure that whatever winged beast that had attacked them at the mansion would not be getting into the building.

He didn't want to think about the consequences of Amelia biting Trinity. It wasn't his place. And despite whatever feelings Selene had for the blonde, she was going to have to accept that Trinity was now Amelia's childe. Adam could still smell the blood and the sweat as Amelia frantically struggled to keep the blonde from dying in the backseat of the car.

"Adam, security has been tightened and patrols are occurring both along the perimeter and on every floor in the building," a thick, chestnut haired vampire by the name of Ewan Holstein, informed the Death Dealer.

"And security cameras are all functioning?" Adam asked turning his attention away from the pacing to face the young vampire.

"Nothing will be able to get in or out without us knowing," Ewan replied, his green eyes moving down the hallway towards the guardroom where Amelia and several doctors where.

Adam regarded the other vampire for a moment. Despite what his title said, Adam knew that Selene was really Kahn's second in charge and if anything, he was Selene's second in charge. Being in the position he was, he had on occasion visited the Ziodex research facility in Budapest for security reasons and had even met Ewan Holstein on those occasions. He was the director of the Budapest research facility during the night, and as far as Adam knew, was handed picked for the job by Amelia herself.

Each of the facilities directors had been selected by the Council, and with their recommendations, the Elders handpicked each one from the short list. The process was long and from what Adam could tell, it involved a lot of politics.

"You were handed picked by Amelia for this job were you not?"

"Yes."

"And your loyalties have always been to the coven?"

"I'm not quite sure I understand…"

"Kraven has betrayed us to the lycans," Jasper's raspy voice cut into the conversation, stopping mid way through his pacing to stare at the older vampire, "He made a secret allegiance with Lucian. He's been alive for the past six centuries."

Ewan exhaled deeply as his mind began to piece the bits of information together. The sudden unexpected appearance of a worried and concerned Amelia covered in blood, had at first startled him. However, it was the unconscious barely alive human, with a fresh bite mark that had caught his attention, and immediately called for the doctors. Ewan was perhaps, more than relieved to see that Amelia had been unharmed. He knew that Marcus had been due to be Awakened sometime tonight, and he had been expecting a visit from the Elder in the coming days after the Awakening.

"Are you questioning my loyalty?"

"At this point in time, I don't care whether I'm offending you or not. My primary concern is Amelia," Adam replied as his dark eyes bored into the green orbs of the older vampire.

"As is mine. My loyalty has always been to Amelia, nothing will change that," the chestnut haired director answered, green eyes hardening.

Amelia stared down at the unconscious blonde as her ears strained to hear the faint beating of her heart. Uneasiness filled her mind, as the anxious wait for Trinity to wake began to take its toll. She had never turned anyone, she had never found anyone worthy and she found the whole process new and rather daunting. Ewan had informed her that it might be hours before she woke. Hours that Amelia didn't think she had, especially with the mansion now massacred by a winged beast and the remaining Death Dealers in the tunnels battling the lycans.

Pale fingers reached out, brushing loose strands of hair away from Trinity's pale face, before gently tracing the bite mark. Dark eyes moved down to the blood stained bandages that wrapped around the blonde's torso. The deep, gaping wound she had suffered from the hands of the winged creature was slowly healing, and Amelia knew from experience that Trinity would be very weak once she woke up.

The thought of turning Trinity had crossed her mind on more than one occasion. It had been an idea, an after-thought, something she'd consider if the opportunity arose. Amelia was not like Viktor, she didn't have an heir or a childe. Trinity was after all, unique and there were perhaps qualities in her that Amelia saw in herself once (before she was turned). It was what drew Amelia to her and perhaps, there was a selfish part of her that wanted to fill the loneliness that she saw shining brightly in her blue orbs, to love and nurture her like her own.

Darkness plagued her world as Trinity struggled to pull herself to the surface. Her senses were beginning to awaken as she drew closer; the rich scent of perfume collided and tangled with the scents of sterility and disinfectants. Her skin tingled at the feel of cool fingers grazing against her neck that caused her to shiver. It was enough to pull her towards the dim light. Eyelids fluttered and she gasped, her body was too sensitive and hyperaware of everything around her.

Something was different. Something wasn't right. She could feel it as the cool fingers drew back and she opened her eyes, looking around wildly at the unfamiliar room. A calming hand rested on her shoulder, urging her to relax and she glanced up to meet a pair of dark orbs.

"It's okay. You're safe," Amelia informed staring down at the bewildered and confused blonde.

"W-What happened to me?" Trinity managed to ask, voice scratchy from being unused.

"You don't remember?" Amelia tilted her head and regarded the newly turned vampire, watching as the gears in her brilliant mind slowly began to turn and piece together the events of the hours past.

The blonde pushed away from Amelia's touch, struggling to get away, wanting some distance as her mind played catch up. A small jolt of pain surged through her body at the sudden movement, her hands quickly moving across to her torso, fingers immediately feeling the bandages. The world around her began to spin, her ears pounded as she was assaulted with noises. She could hear everything - from the soft pacing footsteps just outside the room to the soft beeping of machines on the floor above her. Her eyes could see every detail of the walls around her, every minute detail that she was sure she couldn't possibly be able to see, yet there it all was. Her body was buzzing with energy she didn't know she could possess.

"W-What…Make it stop," Trinity gasped, desperately wanting everything to stop spinning and for the pounding to stop. She didn't think her mind could take it anymore.

"You need to relax Trinity," Amelia instructed, knowing that her senses were going into overdrive.

Trinity squeezed her eyes shut and bit down on her lower lip, only to feel a sharp pain as she accidentally pierced through skin and drew blood. Snapping her eyes open, she choked back a cry as her tongue ran along the newly elongated fangs.

"Oh god… What have you done to me?"
