I own... most of the words. I have taken liberty with lifting lines from the script on occasion, so I can't even claim all of them.

This is VERY AU. The center of Fae power, where Bo finds herself, is in Boston. Frost and Hale were hybridized to make my Frost, and there are other stuff, but that is all in the plot... ;)

I want to thank me beta - Lostlex for her input. This would have been a lot shittier without you! (And if anyone sees her, tell her that I have a bit more lined up... just waiting there.. on my hard drive...)

Or if anyone wants to fill in for her - contact me in a week or so. I'd really hate to replace her, but I kind of like where this fic it taking me so far, and I need a beta...

I dedicate this story to RaziJazz's insanity which came up with the prompt.

Episode 1 – Fae, Fae, Fae world

"Lauren?" Jane resisted the urge to knock as she stepped into the lab. Even though the remodeling they had done to this place was years old, she still thought of it as the 'new labs'.

"I'll be with you in a moment," Lauren replied softly, from a distance.

Jane found herself walking toward the voice, which was partly muffled by the hum and bulk of machines in the room. She caught the scent of the woman she was looking for from behind a screen, and stopped. She realized Lauren was with a patient.

"I was just paged about..." Jane paused momentarily, hearing a quiet yelp in a voice that could not belong to anyone over 10 years of age. She frowned in sympathy, "a case. We aren't sure that it's ours, but considering the others summoned, I figured that it might be a good idea if you came along to pull rank."

Lauren sighed. "All right, I won't be long. I'm almost done."

Jane flagged down a lab tech, "Can I sit here?" She asked, pointing at a bed. The tech shrugged as if to say 'why not,' and moved on. Jane shook her head as she sat on the edge of the bed, her foot tapping the air impatiently.

"Thanks, Doctor Lauren!" The small voice sounded again, along with a thump. The seated woman rose, waiting for the child to jump from behind the screen just as surely as he hopped down from the table. Soon enough a small body skidded the main part of the room.

"Watch out!" The blonde doctor stepped out right behind the boy. He stopped at her call, and looked sheepishly around the room. The raven haired woman smiled. "Your parents should be waiting right outside, if they aren't - wait there, I should be right out." Lauren informed him. The child walked out at a slower pace, and Lauren looked after him, shaking her head with a half-smile. She closed her eyes, the smile still on her features as she turned to the waiting woman. She allowed herself to open her eyes, a more businesslike expression now on her features. "Dead or alive?"

Jane frowned. "You're talking to me. What do you think?"

The doctor opened her mouth to respond, closed it, and went to put together a bag. After a few moments, she nodded to indicate she was ready, and the two women headed for the doors.

"We'll take my car," Jane hesitated. "Explaining why I'm showing up in yours might be a bit challenging."

"And this way it won't be?" Lauren looked up at the woman walking next to her with a cocked eyebrow. Then she shook her head. "You know what, don't answer that, I don't care. Your idea, your call, you get to explain things on scene."

The taller woman smirked. "Let's get to it then."

~~~Bosoton*Fae~~~

The middle floor of the underground car park located under one of Boston's finest hotels was sealed off, but a quick flash of her credentials to the officer standing guard let the two women roll in without more than a half minute delay. "Try to avoid her." Lauren turned her head, her eyebrow beginning to rise in question at the statement. "She might still be mad about you taking over the autopsy of that crazy siren last month."

Lauren nodded thoughtfully. "I didn't think of that..."

"And don't hide behind me too much either. I still need to work her."

"Point taken."

The last few feet until the car was parked were spent in silence, and the two got out of the car looking to all the world as if they had barely ever spoken to one another. Jane's expression was firm, the schooled look of near indifference that she had learned and adopted many years coming as a second nature. She has, after all been to many a crime scene in the past. Both a cop in Boston and before this job. Lauren, on the other hand, was a bit out of her element – she was far more used to patients, solutions, and quiet work than to all the commotion. She drew a deep breath through her nose and squared her shoulders. Coming in on Jane Rizzoli's heels would only get her so far. Out of the corner of her eye she could make out an almost imperceptible nod of approval from the tall detective.

"Hey! You finally decided to show!" The amused call came from the man leaning against the police car near the elevator doors. Next to the elevator, a honey blonde woman wearing a dress and clad in heels stopped arguing with the uniformed cop barring her way and turned towards the two approaching women.

"Jane, please tell Officer West here that as the medical examiner I need to take a look at the body." Her gaze landed on the woman beside the approaching detective, and Jane could almost hear the gears in her best friend's mind shift as she tried to comprehend what the other doctor was doing there.

"Five more minutes, Maura." Jane responded in an attempt to appease the clearly agitated woman. "Frost and I will look at the body and we will probably be able to send Dr. Lewis here home." The blonde in question moved her bag from her right hand to the front of her body, holding it now with both hands, before she shrugged, trying to look anywhere but at the two women.

Maura flared, "Jane..."

"Maura, please," she was cut off, "five minutes. That's all." The two locked eyes for a few seconds before Maura looked down and sighed in defeat. Lauren attempted to hide a sympathetic smile from having dealt with that look herself, knowing that the smile would be misinterpreted by the other doctor. "Five minutes." The ME agreed, "then I'm coming in."

"So what do we have here?" Jane asked her partner as they stepped past the officer and into the elevator, leaving the two doctors behind them.

"Male, mid-thirties, no ID, must have rented a room here in the hotel. The security guard found him about an hour ago." Frost replied as they passed through the open doors. "No blood or guts coming out of him either." Frost added, mildly relieved. Jane merely smirked at him.

"What about the camera?"

"Busted. I had them pull the garage's." Jane nodded as she pulled on a blue nitrile glove, before removing the paper that covered the man's head and pulling out a ballpoint pen. Frost looked back over his shoulder, before putting on his own set of gloves as he crouched down. "The vic's human."

"Yeah," she agreed as she lifted the man's upper lip, and then lowered his bottom one using her pen. "The killer definitely wasn't."

"Oh no..." Frost frowned, while still fixing his gloves, "our side?"

"I hope not." Jane answered contemplatively. "This is sloppy... Leaving behind a feed like this... I don't recognize this kind of kill... Do you?"

Frost shook his head. "No, but it's a good way to die. The man did die with a smile on his face..."

Jane lifted a single hair from the man's collar, her focus on getting this done before Maura made good on her five minute timeline, the only thing keeping her from rolling her eyes at the remarks her partner was making. "A brunette." The detective said casually before smelling the strand and putting it in an evidence bag. With that done she leaned closer and inhaled deeply.

"What is it?"

"He has been drinking. And I smell a human on him – female."

Frost nodded. "Well, at this time of night and with that combo, I think we are going to the bar."

Jane nodded, her expression grave. "Lauren." As she called the name, the blonde doctor's head snapped to her a second before she started to move towards the two kneeling detectives. Maura shook her head in frustration from where she stood out in the parking lot, her lips pursing as she strained to hear what the other three were saying. "Can you recognize this?" Oblivious to the woman she left behind; Lauren knelt and repeated the procedure done only moments ago by the other woman in the elevator.

"Not in here." The blonde doctor finally said while softly shaking her head, "not like this... I need more equipment..." She trailed off. Jane and Frost nodded.

"Take him. Get officer Whyte to drive you to the lab." Lauren nodded to Jane's command, removing her gloves. Jane looked out of the elevator and sighed before getting up to leave. "Excuse me."

She took a few quick running steps and caught up with her retreating friend. "Maura, please wait." Green-brown eyes flashed as the other woman turned to face her.

"Why is she here, Jane? Who is she that she can just come and claim the body? This makes no sense, Jane!" Jane took hold of her friend's shoulder and ran her hand down the length of her arm until she was holding her hand.

"It's from higher up, Maura. I can't explain it any better than I could last month."

"But you will still be dealing with this case." Jane nodded at the statement, Maura sighed. "Then let the lieutenant offer my services. I don't like being shut out of this. I saw the discoloration of the skin above his zygomaticus muscles, which reached the buccinators, and masseters." Jane's eyebrow arched and her head started to tilt, Maura sighed again, "His cheeks." She carried on before the woman before her even had the chance to finish mouthing 'oh'. "I have never seen anything like this. Please Jane." Her tone was low, quiet, imploring while trying to appear as though all was right.

"This is not my call, Maura... I don't have a say in this..." The dark haired detective nearly flinched when the hand she was holding was dragged out of her own.

"You were the one who called her to check the body. You could have called me."

"I had my orders, Maura. I'm sorry, but a kill this strange goes to Lauren's table. A normal looking corpse to ours."

"Fine." With one last huff, the other woman was gone, leaving Jane pinching the bridge of her nose.

"Jane, are you coming?" Maura squared her shoulders she walked back toward Frost, who was calling for her from within the elevator. She didn't fully register the blonde doctor's gaze as she passed her with only a nod of acknowledgement.

~~~Boston*Fae~~~

"Good job pulling her face from the traffic camera."

Next to her, Frost grinned in response. "Thanks." He looked out the window and into the nearby diner as they drove by. "I think I saw her. Do you want to go out and make sure or should I?"

Jane shook her head. "I'll go. If Trick is even halfway right then I want to see her while she is still lucid."

"I'm not sure you need to worry about that... But knock yourself out. I'll go around the block once, call me if you want to speed things up." She gave him a long look as he pulled up to the sidewalk.

"Imagine if we were human cops hearing someone talk like that. We would be hauling their asses to jail them before they could move..." She finally said with a hint of a smile and an almost inaudible exhale. Her partner just chuckled.

"Yes, but this is a unique set of circumstances, and we are talking about the Ash." She nodded at this statement, thoughtful, then opened the door.

"I know, but I still need to see what I'm going to do about Maura, and this little side trip is not helping matters at all." Before he had a chance to reply, she was getting out of the van and closing the door. "And don't you say it. I get enough of that from..." She turned her head suddenly, looking at the diner. "Leave. Now."

Frost nodded and drove off casually, leaving Jane to move alone on the semi-crowded sidewalk. She pulled her coat a bit more tightly around her, making sure to hide her badge and gun, and began making her way to the two talking women. She could easily make out the other woman's appearance from a nearly 100 yard distance, and Jane couldn't help but grin at her chosen attire of skin-tight black and leather. Moving closer, she paid growing attention to the other woman's face rather than her figure, the years she spent hunting people down kicking in with almost no thought on her part.

She almost unconsciously took in the other woman's features. Her high forehead, the thin eyebrows atop dark brown eyes; her nose, cheekbones, lips, and the length of her hair. She was dressed in a low cut black shirt under an almost knee length black coat, black leather pants and high black boots. She ran her eyes along the other woman's jawbone, noting the way her hair moved as she walked, when she realized that the brunette was starting to turn her head toward her. The half smile that had formed when she first took in the other woman's outfit grew, turning from amused to almost sensual as they passed each other on the street, their shoulders barely a hand's length apart. A deeper than normal breath was all she needed to match the scents to the crime scene. She recognized the look she received in return and kept her eyes locked with the woman until it was no longer comfortable. Spotting Frost approaching in the van, she quickly moved to a vacant spot beside the road, raising her arm in acknowledgement and then quickly looking over her shoulder.

"They are going into that alley, we're not going to get a better chance than this, move." She said urgently and she opened the door, nearly jumping into the vehicle before it fully stopped. Frost nodded once and took off, the passenger door slamming shut as they turned into the lane.

Once inside the deserted alleyway, they moved quickly, knowing that time was of the essence if they wished to remain unseen. Mumbling at Frost, Jane dragged the woman he rendered all but unconscious into the van, allowing him to sit with her as she headed for the driver's seat from the inside, and then speeded down the alley. "Don't forget the hood." She could see him nodding to her in the rearview mirror, and so she turned her attention to the road.

The drive to the manor where the Ash conducted his business was uneventful, since once she was cuffed, and a black felt hood was pulled over her head, their captive could do nothing but sit there and yell at them. The two detectives ignored her, choosing to ride for the most part in silence. The woman continued talking as they walked from the van and toward the chambers where the Ash held is audiences. Only after sitting the woman in a chair did Jane take the hood off her head. The seated woman closed her eyes against the sunlight that shone into the room from the tall windows.

Nearly 15 minutes later, they were roughly at the same spot, and Jane felt her patience reaching its fraying point. "I don't think she's lying." Frost said almost lightly from where he rested against a pillar after the woman told them, exasperated by now, that she did not have a clan, bagpipes, or haggis, since she wasn't Scottish.

The Ash approached her then, looking deep into her eyes as he tried to assess her honesty. "Do you really not know what you are?" He asked her, his low voice portraying none of the frustration Jane could feel coursing through her veins.

"What am I?" The woman responded. Then, as the man before her drew closer still – she head-butted him. Before she could think better of it, Jane was straddling the woman, her hand fisting the black collar of a shirt and her canines elongating even as she felt her eyes shift in color. Behind her, the Ash was clutching his bleeding nose. "Forget about me, what the hell are you?" The woman in her hands asked, her voice and scent clearly signaling her panic.

"I'm sorry, it's the Morrigan. She insists on seeing her." Jane let go once she took in the blonde doctor as the blonde rushed in, in a manner so unlike what she usually projected. The entire group of Fae all but took small step back then, attempting to keep up a façade in front of their uninvited guests. Despite the quips and insults exchanged by both leaders, Jane felt quite proud that the two faction of Fae managed to keep decorum, and that she didn't have to throw a man across the entire room to get the Light's point across. Yet.

"Enough!" The Ash bellowed finally, raising his hand. "Lauren needs to examine the girl." At that, the blonde doctor moved towards their captive and calmly asked her to join her, though it was clear to all who stood in the room that her words were not a request. As the Ash and the Morigan turned to leave to a more private chamber to speak, Lauren cast a look over her shoulder and captured Jane's eye.

"That was interesting." Frost commented casually as he strolled toward her.

"I have a feeling that this is far from over..." Jane answered quietly, not trusting the men accompanying the Morrigan who were standing together by the door. Frost followed her gaze for a moment before returning it to her as she spoke again. "I want to go by the department. Do you think I have the time to make it there and back?" She glanced at her watch as she spoke, then frowned. "Lauren is going to hold the girl for about 20 to 30 minutes, and I should be here when she lets her out..." She sighed.

"Text Maura. No matter what the Ash and the Morrigan decide, you can go out for drinks later."

"Maybe."

"Be careful though, Jane. She may be getting too close."

She couldn't help the incredulous face she made at him. "She's Maura. I doubt she even believes in," she gestured around them, "well, anything that can't be scientifically explained to her."

Frost's reply was a shrug. "Don't let her talk to Lauren then," he advised as Jane rolled her eyes. "But I didn't mean she is getting too close to discovering there are Fae. I mean she might be getting too close to you." He tapped his chest over his heart. She scoffed at him. "Just sayin'..." He shrugged again, his hands going into his coat pockets. Jane pulled out her phone.

About 10 minutes later, the two leaders reemerged and gave their orders. Jane nodded and headed for the labs with a pair of heavy shackles. Waiting in the hallway, she listened to the conversation carried out inside. Her frown deepened as she took in the way the doctor was behaving with this newcomer. Her sense of smell told her a bit about the woman, especially when she had half shifted while grabbing her in the Ash's chambers. This woman was well aware of herself and how to use her sex-appeal to her advantage. Her suspicions were confirmed when the brunette walked out the doors, attempting to lead Lauren behind her. "You didn't think it would be that easy, did you?"

"A girl can dream, can't she?" Was the brunette's reply as she dropped the other woman's hand. Lauren looked mortified, avoiding eye-contact with the two women before her.

"Your hands please." Jane hoped that by ignoring this incident, the blonde would feel less embarrassed around her. She was sure that even a reassuring smile might be taken the wrong way at this time.

"I'm sorry. I had to try." Jane shook her head approvingly at the apology as she closed the shackles around her wrists.

"No.. good.. no.. it was.." the dark haired detective felt sorry for the doctor who was now choking on her own words "very informative." The old locks on the chains were a bit rusty and she frowned as she shook the key in them in order to get them to lock. "Where are you taking her?"

"The glass factory."

"Why?" When the lock clicked closed, she finally looked up and into brown eyes.

"It's neutral territory. They're going to give her the Test." The Doctor nearly paled.

"Without training? That's madness!"

"It's not our call..." Jane responded, her eyes moving to the floor before looking back at the doctor. "You should get yourself ready." She added and began moving away, leading the chained woman by the elbow toward Frost and the van. This time, she motioned for him to take the wheel, and got in beside the brunette. "What's your name?" She asked, her voice reaching the registry it usually took while talking with families of murder victims.

"Bo." The woman answered almost defiantly, causing Jane to smile.

"I'm Rizzoli, over there's Frost." Bo nodded, and Jane leaned back lightly against the side of the van. "I suggest you conserve your energy right now. You will need it so that you can watch your back later." Bo nodded at her again, and Jane crossed the small distance to sit next to Frost in the front of the van. He gave her a questioning look and she shrugged.

"Please, tell me what's going on." The woman in the back pleaded.

"We can't do that right now." Frost responded before Jane could open her mouth. "Besides, it might be better if you didn't know just yet."

"What's that supposed to mean."

"Un-bristle your feathers."

Jane clamped her mouth shut so she wouldn't laugh at the expression her partner just delivered in a deadpan tone of voice. She looked out ahead as he continued to speak.

"You are in a very unique position at the moment, and the lack of information is actually working in your favor." Frost said coolly.

"Where is this Frost when we're interviewing people?" Jane commented casually as the woman, Bo, contemplated his words.

"Ah, but you play 'bad cop' so well..." He teased.

She shook her head at him.

It was a relatively short drive to the glass factory and once there Jane and Frost were joined by two of the Morrigan's men. It was excessive; Bo was, after all, shackled and now also behind bars, but it was clear to all four Fae why they were all there. It was not so much to protect Bo, or for protection from her, but to keep egos and politics satisfied.

The factory was run down. It has been years since the place was in use. Which was exactly why it had been chosen. The rust and broken windows kept the more sensible people at bay, while the Fae themselves, or on rare occasions – the Under-Fae kept the more desperate or curious from getting too far inside. The whole building smelled of decay and minimal maintenance, and Jane was itching to get out of there and to a place less grating on her senses.

She had also agreed with Doctor Lewis about her statement that sending someone to face the test not only untrained but with no apparent knowledge of their Fae heritage was cruel and, as the blonde put it – insane. And from the look of things, the girl – Bo. She corrected herself firmly. From the look of things Bo wasn't even half charged. Jane remembered the time when she had felt as hungry as the girl looked, and facing the Test in that state was going to get this Bo killed. She looked around her and continued to think.

When the word came for Jane and the others to take Bo from the holding room where the Morrigan spoke to her, it seemed that the shorter brunette was coming to grips with what she was about to face. "So what am I facing here, huh? Big-bad nasties, the Loch Ness monster?"

"Under Fae." Jane responded as she slipped the room key back into her pocket after locking it. Trying to breathe without smelling anything was hard. And annoying.

"Under-what now?"

"Under Fae." Jane repeated, slower this time, as she took the other woman by the elbow and began leading her down the corridor and toward the rink. "Those of our kind that don't exactly fit in the human world." Bo looked at her, jaw agape, but she pressed on, "Very old, very dangerous. You'll face two." She kept her voice low, so that the Dark Fae guard walking in front of them wouldn't hear her.

"And what are my chances?"

"I wouldn't bet on you."

Jane kept her attitude cool and detached as she attempted to figure out the distance from them to the other man, and whether or not she had enough time to execute her plan. When Bo stepped in front of her, she realized she just may have the opening she was looking for.

"Have I spit in your coffee? What is your deal?" Bo demanded.

"Kiss me." Jane's dark eyes flickered to the woman standing next to her for a second before turning back to the hallway.

"Wow..." she couldn't tell if Bo was angry or just incredulous, "are you bad at reading women." She deadpanned, and Jane finally looked into her eyes.

"We don't have time for this," her eyes flicked back toward the doors, "you need all of the strength you can get, so take some of mine."

"Will I kill you?"

"Just kiss me." She wasn't even finished talking when she threaded her fingers through the other woman's long hair and pulled her close, crushing their lips together. She could feel the other woman feeding on her energy immediately, the sensation intensifying as Bo grabbed two fistfuls of her jacket's collar and pushed her against the wall. When she thought she could take no more she forcefully pushed the other woman away, and took a deep breath as she attempted to stop the world from spinning.

Meanwhile, Bo seemed to be cresting a wave of energy and joy. "...you feel that? It felt like the fourth of July in my mouth!"

The detective took a ragged breath and pushed herself off the wall, nearly gagging at the smell. Something seemed to dawn on the smaller woman then.

"Hey, you stopped me!" She exclaimed, still panting. "No one has ever stopped me before."

"Fae are different than humans. Your powers won't work the same on all of us." Jane explained briefly and took the other woman's hand, heading once again towards the rink.

"How am I going to beat these guys?" Bo was scared. The rush of feeding was gone, and things seemed to get cleared and cleared for her. She wasn't shaking though. That was good.

Jane looked down at the woman by her side, she felt almost sorry for the frightened woman. "You need to be faster, stronger than they are. They are going to underestimate you. Use that to your advantage."

"I misjudged you." Bo admitted softly, "got any other advice?"

"Don't get killed." Was Jane's only response, as she was well aware that from where they stood now, they could be heard from inside the main part of the factory.

"And you're back to being an asshole. That's nice..." Bo mumbled as she was dragged behind Jane and into the outer edges of the rink. The detective felt Bo freeze when she first laid eyes on her opponent.

"He's big, but he's slow." Jane hoped that her tone comforted that other woman somewhat. "These are your weapons," she pointed at the rack to her right that was covered with swords, axes, daggers, maces, and other weapons, "choose wisely." Her eyes swept the room as Bo crossed in front of her toward the rack, and she nodded almost imperceptivity at Frost, who had pulled Lauren to his side as she passed next to him. "Good luck." Moving quickly, Jane made her way up to where the two were standing, stopped at the blonde's right, and crossed her arms over her chest as she looked down at the two in the now cleared arena.

The first battle went by quickly. The giant Under Fae fell dead in less than five minutes, but Bo was totally unprepared for the second opponent. Jane reached down, clasping Lauren's wrist when the woman made a strangled noise at the swiftness of the Under-Fae's move. She exchanged a look with Frost. All they could do now was hope for the best.

"I don't..." Lauren started, then stopped. Jane turned her head down to look at her, but Lauren opted to let the sentence die rather than finish it. Jane gently squeezed her arm in reassurance, and almost managed a smile when she felt the blonde doctor reach up to squeeze her wrist in return. When the knives fell from the brunette's hands, the strength of the hand grasping hers intensified.

"Bo! Wake up! Wake up damn it! Bo, wake up!" Jane sharply turned her head toward the noise.

"The human girl..." she said in awe, glancing quickly at Frost. He looked as surprised as she did.

"Bo, he's killing you, wake up!" The girl screamed, pleading with her friend as one of the Dark Fae restrained her from rushing into the rink. The relief that washed over Jane was almost palpable when she noticed Bo's face twitching as the girl's yells and screams continued to echo throughout the large room. "BO!"

That last desperate scream was the final push Bo needed to break the hold over her. And her opponent, once realizing he lost her, fled. The swift motion of a knife incapacitated the man holding the still frantic girl.

"She's mine." Bo declared, her voice even. Jane gently shook Lauren's arm from her own, and crossed her arms once again as she clenched her jaws to keep the small smile she could feel attempting to form at bay. When Bo was once again fully standing, the Ash spoke the old ceremonial words.

"This one has passed the test." He turned to the Morrigan "It has been witnessed." The woman scoffed as the Ash returned his focus to the one standing below him. "Child, you may name your side."

"Neither!" The brunette exclaimed, throwing her arms out, and the entire room gasped and talking erupted. "I choose humans."

The two leaders exchanged glances. Jane finally allowed herself to smile as she slipped away, allowing the small human to help her friend, who had fallen to her knees from exhaustion.

It took fast moves, and faster talking, to allow her and Frost to get the two women back to where they had taken them from. But once there, she offered the brunette some advice on how to keep under the Fae leaders radar, along with her card, and an offer to help when she needed it.

~~TBC~~
