CASE 1: Wolf's Blood

Part 1

Pownal, Maine

"No please! Don't kill me! What did I even do?"

"You damn well know what you did you filthy scum. Take your punishment like a man."

The man crumpled to his knees shakingly in the leafy dirt. His chest constricting itself as breathing was becoming harder and harder. Wheezing for air, suffocating as he choked on the vile that caught itself in his throat.

"Jasper, Billy. Enjoy your newest meal."

Quantico, VA

Standing in front of the mirror Emma stared at her reflection brushing her hands over her black suit jacket. Pulling at the the cuffs taking slow breaths. Reaching up to pull her hair back. Shifting back and forth whether to have her curled blonde hair pulled back or leave it down. A few minutes passing she left it down and reached for her black frames and put them on. Eyes glancing at the picture sitting on her dresser beside them. A soft weak smile tugging at the corners of her lips. Tears slipping out as her heart felt as if it was breaking all over again.

Picking up the picture frame, fingers coursing over the metal design and then over the glass. "I've finally done it, Neal…. You'd be so proud of me. I just wish you were here to witness it…" Shakingly she sat down the photo and wiped away her tears. A few deep breaths and she looked at herself once more. Pulling at the bottom of her jacket as she straightened up her posture. "You can do this Swan. You can show them you deserved this position." She gave herself a strong smile and turned around grabbing her keys and wallet by the door and headed out.

The elevator felt like a long ride to the floor. Emma felt her nerves on edge but she remained firm. This is where she wanted to be. Everything she had done was leading up to this point. Her lifelong dream. The doors opened up and she exhaled slowly taking that first step. The room was large and everyone was sitting at their desks talking, smiling and jabbering on. A more calm smile perched at her lips as she tapped her fingers to her hips.

"Agent Swan?" A kind voice asked her from behind. A blonde haired woman with a fair complexion came from the right behind her. Walking up from her desk and extending out her hand.

"Yes, that would be me." Emma spoke happily. Delivering her best smile to show as she extended her hand in return shaking the other womans hand.

"I'm Agent Jareau but you may call me JJ. It's a pleasure to finally meet you. I've heard some really wonderful things." Retracting her hand she tucked back her hair and turned to the side. "Come, let me introduce you to the rest of our team."

"It's nice to meet you too JJ." Dropping her hand to her side Emma nodded and followed behind her towards the row of desks. Her heart raced a little as her nerves seemed to have returned. Not the best ideal emotion to have for her first day at the BAU.

"Everyone, this is Agent Swan. She'll be taking the open position." JJ said gesturing towards Emma with a smile.

One by one the all stood up from where they sat and walked over. Calm approaches, some with hesitation as they slowly introduced themselves.

"Pleasure to meet you, I'm Agent Derek Morgan."

"Agent Spencer Reid."

"Penelope Garcia. I don't really work the field. I'm more the super computer wiz that works their magic."

JJ looked around and up to the office and looked at Emma. "Hold on one moment. Make yourself comfortable and everyone will be happy to help you with that." She gleamed looking at the trio before trotting off upstairs to Hotch's office.

Emma pulled her hands behind her back and entwined her fingers together. Rubbing her lips together unsure of where to begin. She never really found herself good at mingling and socializing with others. Let alone especially after Neal's death. "It's really nice to meet all of you." Was all she could come up with. Wonderful, what a great first impression to her new team on the first day.

"Are you feeling alright? I feel as if we are making you highly uncomfortable right now." Reid asked tilting his head, brows furrowing as he looked at Emma.

Sucking on her bottom lip Emma smiled, "No, I'm perfectly fine. I'm sorry. It takes me a little to warm up to people unfortunately. Not my strong suit it seems." She sighed. Ears perking up at the woman's voice that projected behind her.

"Well that obviously won't work around here. You need to find yourself comfortable with your team otherwise it makes the job that much harder than it already may be." The brunette stood now in front of Emma. A strong jawline, gorgeous brown eyes piercing into Emma's green one's. Eyes wide as she cocked her head back slightly. Observing the blonde before her. "You must be Agent Swan, JJ was telling Hotch and I that you have arrived." She cocked a partial smile while crossing her arms. "Agent Mills but please, do call me Regina." She said sternly extending out her hand after pulling it from across her chest.

Emma couldn't help but find herself staring at the strong woman. Rather frightening she seemed at first compared to the other's she had met. Emma shakily returned the gesture and shook her hand. "I'll get used to it. I always do. It's nice to meet you Regina. You can just call me Emma." She attempted to sound more confident in herself. Confidence, that's exactly what she needed to remind herself.

"Good, see to it that you do. We cannot have you standing around like a fool while we profile everything. And Swan will work just fine in my book." She said smugly. Her eyes glancing at the team behind her.

"Excuse me." A man said from behind Regina as he finished walked down the stairs. Regina shifting to the left as he interjected their conversation. "Nice to meet you Agent Swan. I'm Agent Aaron Hotchner and I'm sorry to cut this all short but I need everyone to gather in the room. We have a case."

"Really? Already? I just…" she whispered under her breath watching as everyone followed behind him she stayed behind. Slowly following behind them. Rubbing her hands together internally yelling at herself. They all had been working together for so long it seemed and here she was wanting to be apart of that. It was welcoming for the most part that was. Her first day there was already a case. It was exciting and even more nerve wracking at the same time.

Walking into the room with a round table Emma walked over to the empty seat between Reid and Regina. Catching Regina turning to glance over at her. Emma gave her a small smile as she took her seat and looked over at Hotch. Hands folded on the table in front of her eager to find out what the case was.

Passing out a file with documents to each member at the table Hotch took his seat shortly. Opening it up his own. Shuffling through papers. "The Pownal police have contacted us to help out in an investigation. There have been a couple of incidents around the area where men have been found mauled or in pieces."

Opening up the file Emma's eyes widened. Her stomach churned knots at the images of the victims before her. Holding her best composure she took it all in. Scanning for details anything that could possibly stand out. This was what she had been waiting for. Her strong suit of finding things and observing details about a person. Though photo's were a little different sometimes but she normally found it easy to grasp the concept of the scene.

"How many victims are we looking at here?"

"They believe there to be at least five victims but only two they have been able to identify so far."

"It's shocking to see that they have been able to discover that much with how the decaying process seems to have worked. Let alone the fact the bones looked as if they were spread throughout the scenes. Did they find all the bones to each of the victims?"

"That I'm not sure of. But I believe they are still working on gathering everything they can together."

"And all the victims were found in different locations spread throughout the park?"

"Yes. There isn't much around there and there is always a lot of activity between park rangers and hikers so it's curious to how they were dumped there."

"Are those animal marks?"

"It appears that way yes."

"You know it wouldn't surprise me if the body was just dumped in the woods and left for wild animals to eat."

"Yes, but there have been multiple variations of attacks like this-."

"It looks like they are all men with similar features." Regina said glancing up. An intensified look piercing at Hotch.

Before he was able to speak Emma interjected her voice a little shaken despite her assurance to what she observed. But she wanted to fit in and show them her determination. "All the marks on the bones and remaining flesh to some of the victims appear to look the same."

Regina looked over at Emma and stared, "How can you tell that?" Her lips curling as she pursed them together.

"Well… at the close-ups of each of the wounds from each victim the scars and teeth marks are exactly the same. I'm sure if we looked at them in person you could tell a lot easier." She said proudly. "How can you tell that the men all have similar features when there are only two victims so far that they have been able to identify?" Emma remarked arching a brow, her smile widening feeling triumphant. "And what if they weren't dumped there? What if this was a game to the unsub?"

The rest of the team sat there, eyes shifting back and forth between Emma and Regina as they passed details back and forth. Glancing at one another tilting their heads. Garcia smiling trying to contain herself.

"Oh really now? And I just believe since we can tell between the two identified victims that it appears to be more than a coincidence." She said chewing on the inside of her cheek. "We need to look at all aspect's Swan. What do you think would make the unsub act as if this was a game?"

"Well, it's open terrain. It's a nature park. Who's to say that the unsub hadn't used this to their advantage? What if they know this area. They could possibly be a frequent hiker or even a hunter."

Regina's nostrils flared as Emma continued on. Eyes fixating on the blonde she turned to look at Hotch, "So why are they just now coming to us about this? What changed?"

Emma continued to sit up straight, her fingers wrapping around the folder as she inhaled slowly. Unsure if she should feel proud of herself or rejected to the idea Regina seemed to dismiss her so easily. Swallowing back she glanced at the rest of the team. Their eyes on Hotch and then down at the papers. So many thoughts running through her mind. She found herself wanting to dive into this case unlike anything else. That was surely something new. Not something she should be anxious about. Did the others ever feel like this? Shouldn't she feel remorse or numb over the situation? It seemed as if it should be something repulsive to her that makes her stomach do somersaults or something. But it didn't…

Hotch waited a moment or two to see if anything further was to continue between the two woman. As silence filled the room he cleared out his throat and rubbed his lips together before looking down at the papers and placing them down in front of him. Hands folding together as they rested on top of the file. "The fact that they just recently identified the two bodies. One being most recent and the other they propose to be the first target. The coroner has discovered a few things and when we get there I want Reid and Emma to go and check it out. Regina and Morgan I need you both to scope out the surrounding areas to where the victims were found and JJ, I want you with me, so we can speak with the officer in charge." He turned and glanced to Garcia. "I'll need a list of information dealing with the victims and what they were doing up to the point of death. Anything you can find out about them will be helpful to our finding out a profile."

"Our flight leaves in a half hour." Hotch finished saying as he stood up slowly. Everyone nodding their head and getting up from the table. "Regina can you stay behind for a moment. I need to speak with you."

"Of course." Regina replied a little curiously.

Standing up and following behind the group as they talked to one another Emma remained silent. Glancing over her shoulder at the brunette who was sitting back down in place. Pushing the center of her glasses up back onto the bridge of her nose. Chewing on the inside of her cheek while raising the file up in front of her face. Flipping through the pages as she continued to try and analyze the details. Nothing much really was there past the point of their discussion. At least nothing that she was able to detect that was.

"Don't let Regina get to you, she can seem a little tough at times but she does mean well." Morgan said patting Emma's back.

Lowering the files after nearly jumping from the abrupt touch Emma looked at Morgan. Nodding her head a brief moment of silence as she attempted to gather her thoughts. "She hasn't gotten to me…" She mustered out.

"Sure she hasn't. That's why you're still staring at those papers right?" He smiled with a subtle chuckle. "You're not fooling anyone here Emma."

"I...wasn't trying to fool you?" She stated calmly.

"Sure you weren't. Don't forget what we all do here. We know perfectly well how to read one another. There are no real secrets here." A more noticeable laugh as he patted her back before walking towards a desk to grab his coat.

Everyone walking towards the elevator and Emma just gave a weak smile. Another slow breath as she pulled at the bottom of her jacket and trolled behind them. This was going to be interesting.

DING. The elevator doors opened and she took the final step inside. Shifting to the corner resting her hands on the rails. Her head rested back against the wall. Giving everyone a soft smile as they looked at her. "I'm fine, don't worry about me."

"You think you got this?" Morgan asked her.

"I think I got this." Emma assured him. "In fact, I know I go this."

Crossing her arms and legs Regina sat back in her chair. "What's this about Hotch?" She asked him curiously. Arching a brow. Staring at him and his ever so calm demeanor.

Gathering all the files together and tapping them in place on top of the table Hotch looked up at her though his lids. "I think you know perfectly well what this is about." He stated.

Cocking her head slightly Regina pursed her lips together. Her arms crossing over her chest. Arching a brow, "Are you seriously wanting to hold me back and give me a speech about how I spoke to Swan?" She said agitated at the situation. "Because I don't really care if I hurt her feelings at all. If she is going to be apart of this team then she's going to need to suck it up."

"Look, I know you are still upset about Prentiss leaving the team after her promotion to Interpol. But Emma is apart of our team now. I'm going to need you to work with her and help show her the ropes around here. That's why I'm going to have her tag along with you now at the crime scene and have Reid and Morgan talk to the coroner." Hotch glimpsed up. His straight posture with the folder at his side.

"You have to be kidding me Hotch. This is ridiculous. I-"

Cutting her off he shook his head, "I don't want any excuses Regina. There is no reason for this attitude of yours. I suggest you start with getting along with her on the flight there. It's going to take us awhile." He nodded his head and gave a quick partial grin. Walking over to the door and opening it. Waving for Regina. "Now we should get going. The team should be waiting for us."

Biting her tongue Regina glared. Frustrated and her blood boiling. This was absurd. Uncrossing her legs she grabbed the file in front of her and stood up. Proceeding out of the room. Cursing under her breath after distancing herself from Hotch. "Curse you Swan…" she uttered under her breath walking into the elevator. Tapping her foot and crossing her arms.

The door shutting in front of her. Hotch standing there on the other side with his hands folded in front of him.

Silence as Regina stared at the doors. Her breathing regulating itself as she calmed her nerves. This blonde better not give her a hard time or get in her way. If Emma Swan thought she was going to replace Prentiss she had another thing coming. Regina's lips curled upwards, primping her hair when the doors opened. Brown eyes smiling as she glimpsed at the other woman. He said to show her the ropes, that's exactly what she was going to do.

Emma had taken a seat on the plane. Still flipping through the papers and pictures in the file over and over again. Headphones in and from time to time she'd glance up to see if anyone was needing her attention. They all seemed off in their own worlds together. Apart of her felt bad she didn't try to blend more with them but they seemed to respect her space all the same. The one time she glanced up she caught Regina walking towards her. Taking a seat across the table. Pulling out her headphones Emma looked at her with a meek smile.

Brushing her hands over her sides Regina took a seat sliding into the booth like area. Folding her hands and resting them on the table. Brown eyes looking into emerald ones. Trying to return the smile, though rubbing off slightly forced. "Swan." She said pursing her lips together. Her cocky attitude showing through.

"You know you can just call me Emma right?" She said trying to lighten the mood. Feeling a little tense from Regina's presence.

Rubbing her hands together Regina merely stared. "Swan will work just fine for me." She stated, "Now then, I wanted to… 'apologize' for my attitude earlier. Let's just say I'm not the most welcoming as the other's sometimes." Regina cocked her head up a little as she shifted in her seat. "Also Hotch decided to switch things around. You will be accompanying me at the crime scene and Morgan will go with Reid."

"Oh…okay….." Emma rubbed the back of her head feeling her nerves arising once more. Something about this woman seemed to set them off more than normal. At least she managed an apology. Though not a very promising one that was for sure. "Thanks… I guess…" she finally said after seeing Regina arching her brow at her. "I can't wait to work beside you Regina."

Sitting back resting an arm on top of the booth Regina looked away. "If you are going to hide away like a little turtle I don't care to keep you around like a pet. You are either in this altogether or not at all. I am not a pet sitter Swan. I don't like mumbling when I'm trying to work. Do you understand me?" Regina tilted her head looking back at Emma. A stern serious expression painting her face.

"Y-" Emma paused briefly channeling her inner self. This wasn't like her. Not at least before Neal's death it wasn't. She used to be stronger and in your face. If she was going to work with Regina she needed a way to return back to that woman. "Yes, of course. We are a team after all. I promise you that I'll show you everything I am made of and you won't be disappointed."

Smiling widely, a almost seductive and pleased one at that curled up her lips. "Good, that's exactly what I was hoping to hear."

Pownal, Maine

Walking through the grass Emma knelt down. It was most uncomfortable surveilling the area in the pantsuit she was in. Wishing she wore more comfortable clothing. Though she didn't want to give off a bad first impression. But seeing how some of the other's weren't always dressed up so nicely now she knew to wear something a bit more...her.

Looking at the broken branches, bunched up grass and misplaced dirt Emma rested her hands on her knees. At this level it was far much easier to check things out. Body shifting with her, no sound but the wind rustling past her Emma looked from tree to tree. Noticing the rocks and splattered blood ahead. "So there's a mountain trail here right?"

"Yes Swan, there is. Why?" Regina said bitterly as she slowly stepped around. A hand in her pocket, eyes darting around the area. Pointing at where Emma was. "Right where you are kneeling is where they found the recent victim."

Slowly standing up patting her hands on her knees Emma brushed her hands under her jacket and rested them on her hips. "Because it looks like the victim left a nice trail from where he might have ran from. The disturbance in the grass along with the minor blood splatter from the wounds that was inflicted upon him coincide." Moving in the direction of the trail Emma found herself entranced.

"And just what do you think you're doing Swan? You can't just go galavanting about the crime scene by yourself. You don't even know what animal had done this and it could still be out there." Regina barked at Emma tapping her foot.

Pausing in her trail Emma turned halfway around, her hand brushing under her jacket revealing her gun. "I think I can handle it. I want to try and get as much information for the profile that I can while everyone else studies the victim. Maybe we can figure out what kind of animal had done this."

"It was probably a bear or something that happened to find the victim when he was escaping whoever did this to him. And hold up I'm coming with you." She rolled her eyes and brought her hands to her sides in aggravation. Following behind Emma nearing her side. "I don't know what you think you are going to find Swan. I've walked this trail earlier with the officers and I didn't see anything unusual."

"Doubtful it was a bear that finished off the victims." Emma glanced over her shoulder smiling at Regina. "That's the difference between you and I, Regina. I look at every little detail out in these types of terrains that you probably wouldn't ever think to look. Which isn't that the whole point in our profession?" She grinned cheekily. Her eyes skimming the grounds following the broken leaves from the brush.

Crossing her arms over her chest Regina snarled. "Do not insult me Swan. I know very well how to observe things past the untrained eye. And we should be meeting back up with the team soon anyways to tell them our discoveries."

"Well I'm not done discovering and I do believe earlier on the flight here you told me you didn't want a pet. Well, how about a partner, a teammate." She said cooly still tracking down the terrain. Stopping near the mountainside. Looking around for any signs of struggle. Hands resting on her hips, jaw dropped slightly. "Huh…" Emma questioned under her breath. Lips rubbing together in curiousity. She found herself stumped.

"See, nothing is here. We trailed all the way back to where I started and see once again, nothing." Regina said pointedly.

BUZZ, BUZZ, BUZZ.

Regina's phone went off in her pocket. Pulling it out and flipping it open Regina picked up, "What did you find out?"

Emma watched Regina subtly pace back and forth with her hand on her hip. Flipping her hair back as reached to rub the back of her neck at one point. Taking notice to how Regina's lips continued to rub together as she was listening to whoever on the other line. Emma crossed her arms and walked circles around Regina. Still keeping an eye out for anything possible.

Her eyes followed Emma as she noticed her circling around her. Fixated brown eyes on her golden blonde curled hair. Regina straightened her back and halted where she was. "Thank you, we will regroup at the sheriff's station as soon as we can." Closing the phone Regina stuffed it back in her pocket and looked at Emma with wide eyes. "Swan, we have some new information and need to regroup. Let's go."

Unable to hide it a small smile tugging at the corners of her lips Emma nodded, "Alright, what did you find out? Any leads?" She said following behind Regina.

Staring straight ahead Regina started to speak. Her voice low and almost cold, "Well for one you were right…." An almost sour taste felt left in her mouth at the admittance. "It wasn't a bear, it was a wolf. Reid studied the marks that were grinded into the bones and torn ligaments that remained. But there was something else that has them puzzled and I think the trail we found might signify something. Hopefully Hotch and JJ were able to get more intel on the surrounding location with Garcia's help. It might help us with profiling the unsub."

"What do you think the trail signifies? It comes to a deadend remember?" Emma said moving up to walk beside Regina.

"Well you seemed pretty caught up in something while standing there staring at the mountain stone. What did you see that had your attention Swan?" Regina asked her curiously. Her hands down by her side swaying with her movement as she climbed over the hill.

Looking back from where they traveled from Emma paused in her footsteps. "Something just felt off. Like we were missing something. I feel like I should have looked closer or trailed back and observed the disturbance. How was the victim discovered?"

"Hikers. The man stepped in some of the victim's bile. At least that is what the ranger had said they told him." She paused looking at Emma. Watching the woman turn in circles. Staring back at whence they came. "Why?"

"Bile?" Emma whispered under her breath.

"Swan what is wrong?" Regina stepped over towards her reaching to rest her hand on Emma's shoulder.

"I'll be right back. I think that's what I'm missing." Emma inched away and darted off over the grassy terrain back towards the mountain side.

"Missing?" She whispered before noticing Emma taking off. "SWAN! Get back over here! It's dangerous!" Regina barked at Emma. Growling under her breath as she took off not long after her. "Damn it Swan…." She gritted through clenched teeth. That girl is going to get herself killed one day… Regina thought to herself trying to catch up to her teammate. And how fast does she run? She paused and tried catching her breath. Brushing her short brown hair out of her face. Looking for Emma. "SWAN!" She called out. Listening for a response but nothing. Quickly Regina took off again to hunt her down. If she couldn't find her she was going to have to call for help and that was the last thing she wanted.

In her own little world Emma found herself entranced on the path. Slow steps tracing backwards. Eyes lowered taking in every single detail. She noticed something earlier but she wasn't sure about it. Now that she had that information it made more sense. Out of the corner of her eye something caught her attention. Emma lowered herself to the ground towards some bushes on the lower end of the mountainside.

Pulling a glove from her back pocket Emma slipped it on before steadily reaching into the bush. Hand patting the ground nearly losing balance until she felt a hand tug on her shoulder pulling her back. Startled Emma glanced over her shoulder feeling her heart race at the assumptions until emerald eyes peered into brown ones. "Regina." She gasped.

"Be careful Swan. What do you think you're doing? We don't have time for silly hunches right now. Come on." Helping Emma back up to her feet Regina took her hand to pull her up. Rubbing her hands together before slipping one in the left pocket she started walking back on their original path towards the car.

Lowering her head Emma glanced back over her shoulder after standing back up. Sighing quietly brushing her hands over her face and over her pulled back hair. "Alright…. I just thought…" She started speaking before just letting it die out. They had no idea how much longer until the unsub killed again and now wasn't the time to go off of hunches. She needed to clear her head and they needed to regroup. A fresh new insight was well needed.

Getting into Regina's black mercedes Emma shut the door and buckled up. Lost in her head trying to place the pieces. Configuring her facts on how to help place together the profile with the team.

Regina shut her door and turned on the engine looking over at Emma. A faint smile pulled at the corners of her lips as she observed the other woman talking to herself under her breath. Seeing Emma's eyes shifting back and forth as if she was walking the scene all over again. A light chuckle escaped her under her breath as she shook her head and turned back to face straight ahead. The car moving down the dirt road. Her smile widening.
