Three Months Later

Sam, Dean, and Grace were in the hotel room researching hunts late one night.

"Hey Grace, are you ready to go after something besides poltergeists and spirits?" Dean asked as he looked up from a newspaper.

Grace turned away from her laptop to grin at him. "Of course! It would be nice to actually fight something I can get my hands on," she replied and Dean handed her the paper he was reading.

"Animal attacks increase in southern Utah," Grace read aloud and then looked up at the brothers.

Sam glanced at Dean. "Could be a black dog, or werewolf.," he suggested and raised an eyebrow. "I wonder if it's true that werewolves and vampires are huge enemies," Sam added curiously.

Grace shrugged. "I don't know. I guess we'll find out if it is a werewolf," she replied and Dean stood up.

"Let's get moving. The next full moon is in five days and Sam and I will have to pose as animal control or something to find out where the attacks are centered," he said while pulling his jacket on.

Grace slid her laptop into its case before standing up. "Do you want me to drive so you two can sleep?" she offered and Dean nodded, tossing her the keys before she grabbed her bag and waited on the brothers to get ready. Soon all three were walking out of the room and piling into the Impala.

The trio had become quite close over the three months and trusted each other completely. Their hunting techniques worked well together and they could sense when each other needed help. Dean had started letting Grace drive the Impala more often and was finally convinced she would not scratch it. There were a few awkward moments between Sam and Grace. Most of the awkwardness was because of Dean's comments though and they had an unspoken agreement to not discuss it afterwards. Grace and Sam continuously searched behind Dean's back looking for a way to get him out of his deal, but they had not had any luck yet.

The group was soon on their way to Utah with Grace driving and listening to modern rock while Sam and Dean slept quietly for once.

…

Grace pulled into a hotel parking lot and then shook Sam and Dean awake. "Rise and shine boys," she said with a grin and then caught the jacket Dean chucked at her that he had been using as a pillow.

She laughed and then tossed it back at his head, which he caught just in time.

"I'll go get us a room," Dean said as he got out of the car and stretched before putting his leather jacket on and disappearing into the hotel office.

They had started staying in one room to save money once Dean was sure Grace would not drain them in their sleep. She would lounge in one of the chairs and listen to music or watch movies on her laptop.

Dean had taught her how to hustle pool and cards and she excelled at it, ending up with enough money for a laptop upgrade and a cell phone. One time a large, semi-drunk dude that she beat tried to attack her and she literally threw him out of the bar. Sam and Dean had a hard time keeping a straight face, but after all the years of practicing, they managed it. She passed it off as adrenaline to the witnesses, but that had been the only time she had slipped up with her abilities in public.

Dean returned quickly and they grabbed their bags and entered the room.

"So who are we posing as today to get into the morgue?" Dean asked once they got settled in.

Grace did not comment since she would not be going with them into the morgue. She was too young to pass for any government official, so she would stand outside the morgue and listen to the conversation.

Sam shrugged and quickly looked up the address of the morgue. "I think the simplest thing is to go as FBI and say the case was transferred to us and we needed to see the bodies," he suggested and Dean nodded in agreement.

Grace reached into one of the bags and pulled out the suites Sam and Dean wore when posing as FBI. "When was the last time you ironed these?" she asked as she held one up and examined the mass of wrinkles.

Sam eyed the suit and then glared at Dean. "I ironed them right before we used them last," he said accusingly at Dean.

Dean held his hands up defensively. "Hey I just stuffed them into the bag when we had to high tail it out of town to avoid getting caught by Hendrickson," he explained and Sam nodded reluctantly, knowing it made sense.

Grace just rolled her eyes and walked over and grabbed the cheap iron and ironing board from the closet. "Once I get these straightened out we'll head to the morgue. If any of the murders were nearby I might find a scent trail," she said and then began ironing once the iron was hot.

"How will you know if you've found a werewolf trail if you've never scented one before?" Sam asked her curiously.

Grace shrugged and finished ironing Dean's suit. She laid it out on the bed and then Dean picked it up and stepped into the bathroom to change.

"I really don't know, Sam. I guess it's instincts, but I have a feeling werewolf scent will stand out big time," she replied and then started on Sam's suit.

Sam nodded thoughtfully. "I suppose you are right. Did Lenore's scent stand out to you?"

"It hit me like a brick wall," Grace told him and then handed him his suit.

Sam nodded his thanks and then stood up as Dean came out of the bathroom, stepping inside to change.

Dean stopped in front of the mirror and pulled at the collar uncomfortably. "I still can't believe I have to wear a monkey suit. Don't feds have any style?" he complained and Grace laughed.

"I guess not. I'm surprised you can pass as a fed while driven an Impala," she told him and then turned to see Sam walk out of the bath room looking quite sharp in his suit. Grace quickly focused back on Dean, but noticed Sam raise an eyebrow at out of the corner of her eye.

Dean did not fail to notice the exchange in the mirror and grinned. "Am I going to have to lock you two in a room together with Barry White playing so you'll get past this?" he said and was rewarded with two bright red faces.

"There is nothing to get past, Dean," Sam denied firmly, forcing the blush away.

Grace jumped up and jerked her thumb towards the door. "I… I think I'll wait in the car," she said and was out the door before they could blink.

Sam shook his head and sighed. "I really wish you would stop that," he said and grabbed his FBI ID that Grace had laid out on the bed. He flipped it opened and quickly memorized the name before slipping it inside his suit pocket.

"And what fun would that be?" Dean said and winked at himself in the mirror before grabbing his ID and slipping out the door before Sam could reply.

Sam shook his head and then followed Dean out to the Impala. Grace was sitting in the backseat for once with her head leaned back and ear buds in. Sam frowned as he climbed into the front seat. The music was loud enough that he could hear it and he quickly decided there was worse music than what Dean listened to.

Dean looked back at her and raised an eyebrow. "Who is that and what kind of music is it?" he asked and started the Impala.

"It's The Thespian by Alesana and the genre is metalcore," she replied and pulled an ear bud out, causing the screaming/singing to intensify. "Want to listen?" Grace offered with a smirk, knowing the answer.

"No!" Sam and Dean said in unison.

She laughed and stuck the ear bud back in her ear. Grace knew how to change topics discreetly and was glad they had forgotten about Dean's comment.

…

Dean pulled into a parallel parking space in front of the morgue and got out of the Impala. Sam glanced back at Grace as she put her iPod away. "We going with the usual plan?" he asked and she nodded wordlessly, not really looking forward to it.

Sighing, Sam opened that door and got out, quickly followed by Grace. "You know you don't have to listen in. We could just tell you later," he offered and she shook her head.

"You know it's easier for me to just listen in. That way I can hear the different tones of voice and hear them if they mumble anything," Grace replied with a shrug.

"You have a point," Sam said, knowing that arguing with her was a lost cause. They had quickly found out that Grace had a stubborn streak that, to quote Bobby, "Rivaled the Winchesters".

Dean looked back from the top of the steps. "Coming, Agent Green?" he asked with a cocky grin and Sam rolled his eyes and joined him at the top of the steps before walking confidently into the morgue and Grace knew they would succeed in getting a look at the bodies.

Looking around, she decided that standing in front of the morgue would look suspicious, so Grace walked down the road until she reached the park a few blocks away. Finding a deserted area, Grace sat down on a park bench. She rested an arm on the back of it and closed her eyes, leaning her head back.

Concentrating her hearing, Grace quickly heard Sam and Dean and focused on them, trying to tune out all the other noises.

"What do you think killed them?" Grace heard Sam ask who she assumed was the medical examiner.

"From what I can tell it looks like a dog or coyote," a man replied.

"Do the victims have anything in common?" Dean asked and Grace could tell he was not as excited about it since it was not a female medical examiner.

"Yes actually, and I'm hoping it's the answer for the missing hearts. Almost all the victims were gang members. My best guess is that some gangs are sending attack dogs after rival gangs and then taking the hearts as trophies. As revolting as it is, I shudder to think what other options there are," the man said and Grace could almost hear him shiver.

"Thank you for the information, maybe we will finally be able to make some progress with the case," Sam said and then she heard him and Dean walking away.

Grace's eyes snapped opened and she broke her hearing concentration, grateful to be able to quit listening. All the sounds in populated areas gave her a vampire sized headache. Standing up, she broke into a jog and reached the Impala just as Sam and Dean walked out of the building. All three of them piled into the Impala wordlessly.

As soon as Dean pulled back on the road he glanced at Grace. "I take it you heard all that?" he asked and she nodded.

"Yes, but I did not concentrate soon enough to hear how many bodies there were," Grace told him and then glanced at Sam as he cleared his throat to get her attention.

"There have been fourteen victims over three months," he said and her eyes widened for a moment.

Grace looked lost in thought. "For only having three nights, that's..."

"A blood bath," Dean finished for her and she nodded agreement.

The rest of the ride was quiet until Dean drove the car into the animal control station parking lot.

"I'm not going to even bother listening in this time," Grace told them and Sam nodded as he stepped out giving her a sympathetic glance. She noticed Dean roll his eyes with an amused expression before the brothers turned to go into the station.

Grace closed her eyes and leaned her head back, wondering what Dean was thinking before she decided she really did not want to know. As the headache slowly started to lessen, her thoughts wondered back to a month after they had started working together and Sam and Dean had found out about her headaches.

*flashback*

"I didn't think that you could get headaches as a vampire," Dean said as he cleaned his guns.

Sam had been thinking about it for a few minutes and suddenly realized something. "You know, Lenore said that drinking dead man's blood slows down your healing ability. Maybe that's why you get headaches. You're not healing instantly, so you are feeling the effect longer that you should," he concluded and Grace groaned.

"Great, so that means I'm stuck with the headaches if I want to listen in on anything other than my regular hearing range," she said before falling back on the bed.

"Great, so you'll be grouchy every time you concentrate on hearing?" Dean said and Grace gave him an 'if looks could kill' glare while Sam chuckled under his breath.

*end flashback*

Her thoughts were interrupted as Sam and Dean opened the door and got back in the Impala.

"All the attacks were centered in the west side of town in gang territory," Dean said and started the car.

"What if the coroner was right and these are gang based attacks. Maybe a gang member was turned into a werewolf and now the wolf side is attacking the enemy," Sam said and Grace nodded in agreement.

"But the amount of victims is still crazy for one werewolf. What if there are two like the case with Madison and her neighbor," she suggested and noticed Sam frown at the idea.

"Two humans and a vampire verses two werewolves. I really don't like those odds, but I think we could manage," Dean said as he drove towards the west side of town.

Sam nodded and then pulled out a map and started marking where each body was found. "We'll have to see if we can find the suspects first and see if they are working together or splitting up. It would be best if we could tackle them separately," he replied and then fell quiet as he focused on his task.

…

When they reached the west side of town, Grace rolled down her window to see if she could find any useful scents.

After a few minutes she suddenly stiffened and glanced at Dean.

"Pull over here," she said urgently and Dean immediately pulled over next to the curb.

"What is it?" Sam asked before Dean could.

Grace jumped out of the car and then looked back through the window. "I think I just caught my first werewolf scent. I'm going to check it out and I want you two to stay here," she explained and the brothers nodded, confirming they would stay put.

Grace walked to a nearby alley before running at full speed towards the scent. It disturbed her at how strong it was, as if there was more than one or two.

She soon reached an abandoned brick building in gang territory. It did not have a roof and the windows were without glass. The bricks were covered with graffiti and Grace quickly realized she was near the gang's headquarters.

She knew if a werewolf was there it would be able to scent her, so she found a building that was a bit taller than the walls of the abandoned one. Grace jumped up and grabbed the edge of the roof and swung onto it.

Crouching to stay low, she sneaked over to the edge of the roof to look down into the building. Her eyes widened in shock and she cursed silently. "We are so screwed," Grace said quietly.

Yeah, cliffy I know, I'll try to get the next chapter up soon as possible. I haven't decided on a name for it though.

Review please :D
