This one's a long one...

Hope you like it...

As hot tears blurred his eyes, Sam slowly lifted his gun to the first woman he had felt something for since Jessica. He pulled the trigger.

I gasped aloud, slapping my hand over my mouth, then glanced up with wide eyes at the boys in the front seat, afraid they'd heard my absurd reaction to one of the books Bobby had given me before we'd left. He said it was a series called Supernatural, written by a prophet about Sam and Dean's lives and that I could benefit a lot more from the books than from asking the guys questions about this stuff.

The guys didn't seem to notice, my gasp drowned out by the heavy rain beating down on the roof of the car. We'd been driving since dawn and, in the late afternoon, had been hit by a severe thunderstorm just as we had entered the New Englad area.

Putting the book down and pulling out my ear phones, I caught the end of the guys' conversation about money issues.

"Do you guys need more cash?" I asked, scooting forward in the back seat to be heard better.

"Don't worry about it," Dean snapped. He'd been grumpy because he'd just washed his car before we left, and now it was getting all muddy again. He really loves that thing. I'm pretty sure I've heard him call it "baby" once or twice.

"Dean, she's just trying to help. She's kinda part of the team now," Sam reasoned. I smiled. I was grateful for Sam. He was making everything just a tad bit easier with his big brown eyes and sweet smile.

Dean shot him a glare that told him never to say that again. I sighed. Dean was hard work, but I could learn to get along with anybody.

Digging in my backpack, I pulled out a carved wooden box and smiled sadly as memories washed over me. I banished them again before the tears could come. Reaching forward, I dropped the box in Sam's lap. Opening the lid, his eyes grew wide.

"What's all this?" he asked.

"Jewelry. Pawn it. You should be able to get some good cash for some of that."

His eyes grew even wider. "Are you kidding?" I shook my head. "Diana, this is some pretty nice stuff. I mean, clearly it's meaningful or was really hard to get." I nodded. "We can't just take this."

"I'm giving it to you, Sam. We all need shelter and to eat, right? This car needs gas, right? Therefore, we need cash. That will get us some, at least for a little while. Take it, pawn it, or I will."

Sam pursed his lips and sighed, reluctant, but finally nodded.

"Where'd you get that?" Dean asked.

"It was mine. Some were from family, some from friends, a couple of the less impressive ones I made." I shrugged.

"When did you have time to grab that?"

"Sam took me home to get some stuff the day after you agreed to train me. I figured it might come in handy."

Dean shot Sam another glare. Sam protested that I needed clothes, but Dean merely fixed his scowl heavily on the road. Sam's face hardened as well.

"Dean, she's a girl. Girls need some things that we can't get and know nothing about."

Dean didn't say anything and Sam rolled his eyes, frustrated. Glancing back at me, his face softened again and a small smile stretched his lips. I returned it and then leaned back again, grabbing up the book once more to finish it off before we got to a motel.

Once in town, Dean pulled into the nearest motel and dropped Sam and I off before ordering us to get a room situated while he went to get food, then he drove away, leaving us in an empty parking lot in the pouring rain. Sam and I looked at each other, him apologetically, me with an understanding smile. I understood. My roommates used to be moody sometimes. At least once a month.

By the time Dean got back, Sam and I had changed and started pinning togther past cases, omens, and compiling a list of suspects and witnesses to interview.

"The victims are all around this Lexington area," Sam said, studying a marked up map, pen in his mouth. He turned to look at me, fists on his hips, his brow furrowed. "But what do they have in common? All different ages, ethnicities, occupations, backgrounds… What does it all come down to?"

"I could take a look at it," Dean offered, setting down a couple of large paper bags.

"No need," I replied, looking up from the computer. "I've got it. They all have the same blood type. Medical records check out, everyone of them is AB positive."

"Wow, really? All of them?" Sam came over behind me to peer over my shoulder at my laptop.

"Yeah, and get this, every one of them has recently had blood transfusions." I looked up at him. "I'm guessing whoever the donor was, wasn't an exact match."

"What about the missing kids Bobby told us about?" Dean asked. "What connection does this have with them?"

"I'm not sure yet, but I do know that all of the victims with the spoiled blood were in the same intensive care unit and likely had the same doctors," I responded, typing furiously as I tried to figure out how to track down each of the kids' records to look for any parallels.

"Inside job?"

"Maybe, but I wouldn't jump right to it. You said never to jump to conclusions before you have all the clues, right? You have to gather what evidence and follow what leads you can get, assess, evaluate, then draw conclusions, right? Well, let's go follow a lead."

Dressed in a navy blue pencil skirt and blazer, flanked by the Winchesters in suits, I sailed through security, received direct answers from doctors and secretaries, and rarely had to wait for anything while playing the part of an FBI agent who was investigating the massive Amber report placed by multiple families in the area. I had a badge and everything.

We had spent the entire next day interviewing doctors, police officers, and witnesses. We had finally gotten a chance to talk to a little girl who claimed to have seen her older sister be taken. But, when we knocked on her door, her father, one of the doctors from the hospital we had just come from who had rushed out the door at the end of the afternoon, was very reluctant to let us in.

"Dr. Tannor, we completely understand your reluctance to allow any strangers near your children," Sam sympathised, "but we are FBI agents and are of no threat to you or your family. We merely want to ask your daughter some questions so that we might be able to track down your eldest and the monster who took her and all of the other children. Please, sir, we just want to help."

Finally, the father agreed and let us inside. While Sam and Dean were talking Dr. and Mrs. Tannor through the procedure of finding kidnappers, which they demanded to know, I slowly began to pull information out of their daughter using her crayons, a technique I had picked up from one of my childhood doctors.

"What does your sister look like?" I asked her while drawing some hearts and flowers on my own piece of paper. She pointed to a blonde stick figure in a pink T shirt and jeans. I smiled at her.

"Very cool! She's pretty, huh? She looks like you!" She nodded. "Hey, can you spell your name?" She wrote out Fiona with a purple crayon. "Fiona. Very good! I like that name, it's very pretty. It's like the princess from Shrek!" She cracked a smile, but it quickly faded. She looked up at me with big blue eyes.

"Where my sister? Where Jill?"

"She was taken, wasn't she?" I asked gently. She nodded. "Did you see who took her, Fiona? If you know who took her, I can try to get her back for you a lot faster."

"You get Jill back for me?"

I nodded. Her big eyes were breaking my heart. She bit her lip, then got to her feet and toddled over to a little bookshelf. She pulled a piece of paper out of one of the books and brought it back to me. I unfolded it. On the piece of paper was a crayon drawing of a very large dog. My breath caught in my throat, but I forced a smile for Fiona.

"Can I keep this?" I asked her in a small voice. She nodded. "Thank you, Fiona." I squeezed her hand gently, then rose to meet her parents and the Winchesters. I nodded. "I think that's everything. Thank you so much, Dr. and Mrs. Tannor, we'll be in touch."

Once back at the motel, I showed Fiona's drawing to the boys. They groaned.

"Is it a werewolf?" I asked. They sighed and nodded. "Oh."

"What? Were you expecting an easy time on your first case?" Dean snapped. I ignored him, just sat down at the little table to further study the drawing.

"So if the kids were taken by a werewolf, does that eliminate any connection to the AB positives?" I asked.

"Not necessarily, but it makes things a hell of a lot foggier," Sam sighed.

"So, what are we looking at? A picky eater?" Dean volunteered.

"No, because wouldn't they have needed to have heart transplants, rather than blood transfusions? Wouldn't a lack of blood have to do with vampires?" I asked.

"Unless the kid's drawing is inaccurate," Sam sighed.

"Well, we don't have anything else to go on," I said.

"Doesn't mean we should go charging in after it. We don't even know for sure what it is."

"I know, I know," I sighed, opening my laptop to look through the pictures of the victims and kids again.

"I'll call Bobby, see if he's gotten any more tips or any ideas of what we're up against," Sam said, pulling out his phone and stepping out of the room, closing the door behind him.

As soon as he was out of the room, Dean closed my laptop and moved it aside. He sat across the table from me and laced his fingers together, placing them on the tabletop and staring across at me.

"Let's get something straight, here," he growled. "You are here so that Sam's concience is clear and so that I can keep an eye on you and make sure you don't hurt anyone. If you jump blindly into any fights and my brother sticks his neck out to save you and gets hurt in the process, I will personally kill you, slowly and painfully, got it?"

"Dean, I'm sorry you feel so threatened by me, but I don't have any bad intentions towards you or anyone else, especially not Sam. He's been nothing but kind to me and I really appreciate the chance you both have given me. I want to help people, not hurt them, I swear." I looked down at my lap. "I understand why you don't trust me, I do. And I'm glad that you care so much for your brother." I met his gaze again. "But I'm not a monster. I don't hurt people. And I hope that, when you finally realize that, we can be friends, because I think you're a really good guy, Dean, and I would hate to remain on your bad side."

Dean eyed me suspiciously, probably wondering why the hell I was being so nice to him when he just threatened to slowly torture me to death. Before either of us could say anything more, Sam burst through the door.

"Grab a gun, load up with silver, and get in the car. I know what's going on."

In the car, Sam filled us in on the conclusion he'd reached with Bobby.

"We've been looking at this trying to find out what's taking the kids, when in reality, it's the kids that are hurting people."

"What do you mean? Baby wolfs?" Dean asked.

"Yeah, basically. There's a big shot in town, creating a pack and trying to turn people through blood transfusions, but they were failing, so he started taking kids so that they could learn to obey him at a young age and then breed once they were trained well enough."

"Why AB positive blood?" I asked from the back.

"We figure this father wolf thing used to be an AB positive. We think he's probably part of the hospital staff and has been switching out the donated blood with some of his own, figuring to use a similar blood type so as to eliminate more risk of rejection."

"Then he could also keep close personal watch on the experimental patients," Dean offered, turning down the road Sam pointed to.

"Exactly," Sam said. "And when that didn't work, he went to Plan B and started grabbing kids."

"So, if I remember correctly, we get the big guy, and all the kids can go home normally, right?" I asked.

"Right."

"How do we know which staff member it is?" I asked.

I saw Dean's eyes brighten in the rearview mirror. "The only one that can't work nights around the full moon."

"How do we know which one that is?"

Sam's eyes met mine in the rearview mirror. "The one that was rushing out the door as the sun was going down."

My eyes widened. "Dr. Tannor."

When we got to the Tannor's, Sam quickly picked the lock on the front door and we fanned out, searching the first floor. Deciding it was clear, we then moved to the basement, slowly filing down the stairs in search of any crated kids. When we found no sign of the missing kids, we split up. Dean went to check upstairs while Sam and I searched the grounds.

The Tannors had a large estate at the edge of town with a huge house and lots of land. Guns at the ready, back to back, Sam and I slowly and silently scanned the backyard. We had just started to move farther away from the house when I saw a glimmer in the dark. It was then that I realized there were several pairs of hungry eyes glittering up at us from the bushes and trees.

I felt the muscles in Sam's back tense and I pressed up against him as a large group of savage looking children/wolves began to surround us. The made a fairly tight ring around us and we were reluctantly about to shoot, but hesitated when they stopped closing in, giving us about ten feet or so of breathing room.

Suddenly there was a loud crash and Dean came sailing through the air, out a top floor window, and hit the ground beside us with a hard thud. He lay there, wheezing painfully, holding his ribs, his tightly squeezed eyes leaking tears.

Just after him, a large wolf leaped from the same window and landed lightly on his feet a couple of yards in front of us, grinning at us with those terrible glimmering eyes.

My breathing quickened, my head swam, and I began to feel feverish as the sound of my own heart became deafening in my ears. Then, the ground suddenly came up to meet me and everything went black.

- Sam's POV -

Maybe two seconds after she was down, Diana had jumped back up again, with a new tension in her muscles. She glared at the wolf leader, Dr. Tannor, and stepped protectively in front of Dean and me, even though I'm a good foot taller than her. Her hands curled into hard fists and her eyes blazed with unknown power.

The wolf barked in such a way that it was as though he were laughing at her. His toothy grin and howling cackle was challenged, however, when Diana ran at him. I was too stunned to cry out, let alone move. The two made contact and, in the same instant, there was a terrible growl, a blood curdling scream, and the sound of Diana's gun going off.

In the next moment, the wolf slumped to the ground and shrank to become Dr. Tannor again. The kids surrounding us slowly became human again and glanced around, dazed and confused.

"Do you know how to get home?" Diana barked at them. The majority of them nodded. "GO!" she screamed. They obeyed quickly, the older ones dragging the younger ones along as they ran as fast as their little legs could carry them.

As they ran past, Dean slowly rose to his feet beside me, one hand holding his ribs, the other pointing his gun at Diana who looked at us, the power fading from her eyes, then crumpled to the ground. I merely looked at Dean, afraid I truly couldn't stop him this time. When I glanced back, Castiel was standing in front of Diana.

"Cas!" I gasped. "What are you doing here?"

Castiel calmly looked between Dean and me, then down at Diana, and back at us again.

"I am here to protect a heavenly weapon."
