Scott stood in the exam room of the vet clinic with a broom in his hands. He moved around the room, sweeping the floor just a few minutes from closing time. Deaton was just down the hall closing up his office. Since the festival had closed that day, everyone had the idea to drop their pets off at the clinic, swarming both of them for the entire day. In the brief break about fifteen minutes before closing Deaton had told Scott to turn the sign over to keep any last minute visitors from arriving. The day had been insane.

Scott picked up the dust pan and swept the pile inside. He made his way to the garbage can just as he heard a car pull up in the parking lot. He set the broom and pan aside and walked toward the front. Scott stood in the doorway as Sheriff Stilinski and Stiles came to the front door. Stiles grabbed the door and pulled, only to find it locked. The Sheriff tapped on the window.

Scott walked to the door and unlocked it.

Stiles pulled it open, setting the bell off. "Dude, we got the photos!"

Scott frowned. "What photos?"

Stiles opened his mouth, but his dad covered it with his hand. "I have the crime scene photos of Kurt Walker. Is your boss still in?"

"Scott, was that the bell?" Deaton called. A moment later, he stepped into the lobby. His eyes widened at the guests. "Sheriff. What can I do for you?"

"I'd like your opinion on our most recent attack, Dr. Deaton." the Sheriff explained.

Deaton folded his arms in front of his chest and nodded. "I'll do what I can."

The Sheriff nodded and held out a manila folder. "Crime scene photos of Mr. Walker."

Deaton took the folder and slowly opened it. "How's the family doing?"

The Sheriff shook his head. "Honestly Doc, I have no idea. Looked like they weren't really sure how to act."

Deaton nodded slowly and looked over the first picture.

"Scott said all his pack was accounted for at the time of the attack." he continued.

Deaton turned toward Scott. "Any traces of an Omega?"

Scott shook his head. "No. Nothing."

Deaton turned the photo over, showing it to Scott. Stiles quickly grew pale and turned away. Scott couldn't look away, not from this. He'd never met Kurt, but he'd seen plenty of attacks in the past few years to know what he was looking at. It was a werewolf attack. Kurt's body had been badly mauled by a werewolf. Scott couldn't even tell what Kurt looked like from the mauling. Whoever did this put plenty of rage into the attack. They didn't want Kurt to survive.

"What can you make of this, Scott?" Deaton asked.

Scott swallowed. "There's a lot of rage in it. The killer didn't want Kurt to live."

"And the wounds?"

He looked at them closely. There was no denying it, they were wolf marks. "It looks like a wolf."

"It would appear so." Deaton said. He turned the photo over and searched through the others.

The Sheriff sighed. "That's not what I wanted to hear."

Stiles shook his head. "That doesn't make any sense. If its a werewolf, then you guys should've picked up a scent." He started pacing around the lobby. Nothing was making sense.

"Okay, so what is there that you can't smell?" the Sheriff asked.

Scott turned toward Stiles. "Mercedes. I wouldn't sense her or her son."

"Bentley's half werewolf." Stiles stated. "He could've done it."

Scott shook his head. "There's no way it was him. Derek was watching them the entire day."

The Sheriff's brows shit up. "You had Derek Hale watching them? What the hell were you thinking?"

"He was trusting his instincts." Derek said. The door eased closed behind him. Several printed papers from the bestiary were in his hand.

Scott and Stiles looked at the papers. "You find out what they are?"

Derek nodded." Ad why we can't sense them."

Stile shrugged. "So, what are they?"

Derek held out the papers. "Mercedes is a siren."

Stiles' eyes widened. He snatched the papers from Derek's hand. "Seriously?"

The Sheriff shrugged. "What does that have to do with anything?"

"Neither Scott nor I can sense her." Derek explained.

"I'm not surprised." Stiles said, staring at the paper. "Siren's originated from the water-"

"But even water has a scent." Scott stated.

Stiles nodded. "Yeah I know."

"Well what else does it say about them?" the Sheriff asked.

"Well in the Odyssey, Siren's were these beautiful women who lured unsuspecting ships to their deaths just by their voices." Stiles explained. "Looking back to the club, that explains a few things."

"More than a few things." Scott said. He looked over Stiles shoulder. "Says here that it's not just their voice, but their entire body is used to lure their prey. That's why everyone at the club couldn't take their eyes off her."

"She doesn't have control over it." Derek explained, crossing his arms.

"Does it say anything about how they kill?"

Stiles shook his head. "No. But it does say that if threatened a Siren will defend itself. And they're fast." He lowered the papers.

"So it could've been the boy?" the Sheriff asked.

Stiles shrugged. "I don't know, dad. I mean, if Scott and Derek couldn't find any werewolf scents in town and a werewolf killed Walker...the pieces would match up, but it doesn't make sense."

"That's because it wasn't a werewolf that killed Kurt Walker." Deaton said, finally speaking up.

All eyes turned to the veterinary, who was seated at the front desk ,still reviewing the photographs of the scene. They were laid out across the desk while he looked them over.

"What do you mean it wasn't a werewolf?" the Sheriff asked.

Deaton looked up. "Kurt wasn't killed by a werewolf, Sheriff. He was killed by someone else."

"A Siren?" he asked.

Deaton shook his head. "No. Siren claws are more finer than werewolf claws. They're made for clean cuts. The markings are Kurt's body are large and heavily jagged. These were made by someone who wanted us to believe that werewolves did this. The weapon itself was blunt, which means it took some force to cause them."

The Sheriff frowned. "Why would they want to frame the pack?"

"They don't like werewolves." Stiles answered with a shrug. "Some vendetta things that they never explained."

"Okay? Well then, which one would want to frame you?" he continued.

"Human or supernatural?" Stiles asked. "Cause the Walker brother's weren't too cozy with Scott and Derek."

"They wouldn't kill their dad over this." Scott said. He looked over toward Derek, looking for a lead.

Derek simply shrugged.

The Sheriff sighed heavily. "Well that's just great. Plenty of theories and no definite culprit." He looked over at the boys. "You guys certainly keep me on my toes."

"Sorry Sheriff." Scott said.

"Don't worry about it Scott." the Sheriff answered. "Come on Stiles."

Stiles frowned. "What that's it?"

"There's really nothing more to do, Stiles." Deaton explained. "We cleared the pack of killing Kurt, that's more than enough."

"Not enough for everyone." Derek mentioned. He turned to the Sheriff. "Does his family know the specifics of the attack? Did they see the body?"

The Sheriff nodded. "No one but the wife. She identified the body and left."

"I can't identify what exactly killed him through the pictures, Sheriff." Deaton explained. "But if i could view the body-"

"I can't do that, Doctor Deaton." the Sheriff answered. "Walker's body was immediately released on the request of his wife and his service is tomorrow. They're burying him at the cemetery tomorrow morning."

Deaton nodded and gathered the papers into the folder. "I understand. Good night Sheriff."

The Sheriff nodded. "Good night doc. Scott. Derek."

"Night Sheriff." Scott called.

The Sheriff retrieved the photos and exited the clinic.

Stiles followed behind him, still reading the papers Derek had brougth with him. "I'm gonna do some more research, see what else I can dig up on Siren's."

Deaton rose from his chair. "Well, Scott, I'll see you tomorrow. Derek. Good night."

Derek nodded.

"Night Deaton." Scott said.

Deaton walked out of the lobby and toward his office, leaving Scott and Derek in the lobby.

Scott turned to Derek. The former alpha was staring at the ground on the far side of the lobby, deep in thought. "What is it?"

"We're still missing something in this." Derek answered shortly.

Scott nodded. "Yeah a suspect."

Derek shook his head. "No. It's more than that."

"What do you mean?"

"Don't you think it's a little convenient that the caravan leader was killed here? On their first festival dealing with werewolves?" Derek asked.

Scott nodded slowly.

"And the immediate burial?" Derek continued. "I mean, you'd think that the family would want to know who killed him? Instead, they're burying him the first chance they get."

"But if they're looking for a confrontation, this would be the reason for it." Scott stated.

"So why wouldn't they tell everyone in the caravan?" Derek asked.

"So you think they're hiding something." Scott said.

Derek nodded. "I think they're hiding a lot."

"So we talk to Mercedes." Scott suggested. "She'll talk to us."

Derek shook his head. "No. Not anymore."

Scott frowned. "What do you mean?"

"The caravan is organized and run by councilmembers. Two council. One to deal with the outside world and one to deal with ours. Mercedes was head of the second council until her father's death. His will reorganized both councils. Mercedes is now the leader of the entire caravan, she won't talk to us." Derek explained.

"Then who was named second council leader?"

"Her brother Lincoln."

"Will he talk to use?" Scott asked.

Derek shook his head. "Not likely."

Scott sighed in defeat. "So we're back at square one."

"Not necessarily."

Scott frowned.

"I'm gonna talk to Mercedes." Derek explained.

"You just said-"

"I know." Derek replied. "But I'm not gonna talk to her at the RV park. If I can get to her in the open, I might have a chance."

"you think you can do that?" Scott asked. "The only chance you'd have would be the funeral and I'm pretty sure the pack's not invited."

"Just leave it to me." Derek said. He turned and headed for the door.

"What happened to following the Alpha?" Scott called.

Derek smirked and looked back at Scott. "That's why I'm going, Scott. So you can still lead."
