So still having network issues but YAY for a looong chapter :) Let me know what you guys think!

Caroline was frozen. She watched as Scott or should she say the animal got into Stiles's jeep and drove away. He was the murderer. He has been killing these people. He wasn't human and with the way Stiles treated him, it seemed like he knew. It all made sense. That's why he was around when the station was attacked. On top of it they were trying to frame Matt!

Caroline wasn't just angry, she wanted justice. This was not fair. She stomped back into the police station.

"I need to talk to you guys," she said to Matt, Elena, Bonnie and Tyler.

"What's wrong?" Elena asked picking up on Caroline's vibe.

"I know who's the killer and who attacked this station," she said.

"Who?" Matt asked.

"It was Scott," she said and they all looked at her confused.

"Which Scott?" Bonnie asked.

"Which Scott do you think?" she said annoyed.

"McCall?" Elena asked and Tyler laughed as Caroline nodded.

"Please, that guy can barely take a punch, he's such a loser," Tyler said.

"Yeah look Care, that doesn't really make sense," Matt said.

"I just saw him transform!" she said and they all looked at her like she had lost her mind.

"Transformed?" Bonnie asked.

"His eyes glowed yellow and he had like wolf teeth!" Caroline said not believing her friend questioning her. Could she really make all of this up?

"Caroline are you sure?" Elena asked.

"You think I'm lying?" Caroline asked offended.

"Wolf teeth? Are you saying he's a "werewolf"," Tyler joked, "Yeah right and I guess I'm one as well," he said sarcastically.

"I'm serious!" she said getting angry.

"Care, we've known Scott since first grade," Elena said.

"Well technically we don't actually know him," Bonnie said.

"Still, I mean it's a bit of a stretch," Matt said.

"Then what? You're telling me I imagined everything?" she questioned them and no one had the guts to tell her yes.

"We need to question them tomorrow at school," she said scheming, "Elena you chat with Scott cause he obviously likes you, I'll chat with Stiles because he obviously likes me and Matt you talk with Aria because, well I don't know but it's not like she likes Tyler," she said.

"Everyone likes me," Tyler said arrogantly.

"Fine, then you chat with her," Matt said sarcastically.

"Fine, I will," Tyler said missing his sarcasm.

"So let me get this straight, you think Scott is a killer but you want me to talk to him?" Elena asked amused.

"Well, yeah," Caroline said.

"I'll support you," Bonnie told Elena just as amused.

"And what? They must just admit they killed someone?" Matt asked.

"You must trick them and catch them in the act," Caroline said as if she was a detective.

"Yeah, okay," Matt said thinking she was crazy.

"My mom could have been killed tonight!" she said emotionally and everyone gave in.

"Okay Care, we'll talk to them okay?" Elena said but she knew there was no way Scott was whatever Caroline thought he was. He was just plain old Scott. She was more worried about Caroline and her state of mind.

Derek was silent in his car which was unnerving, just like was something different though, it seemed like he wasn't just moody, he was angry.

"Are you angry?" I asked him but wondered if speaking was a good idea.

"You drank his blood," he said through gritted teeth and I notice his knuckles turn white on the steering wheel.

"You think I wanted too?" I asked him remembering the horrific taste.

"You could have said no," he said simply.

"I couldn't, I need to make sure everyone is okay," I said and Derek laughed.

"You were almost killed and you have to check to make sure everyone is okay?" he asked. I have to say I did see the irony but I needed to know no one else was hurt.

"You make no sense," he said shaking his head.

"And you suppose you do?" I asked him but as expected he said nothing. I rolled my eyes.

"No wonder you have so many friends," I said sarcastically in a whispered tone.

"I don't need friends," he said adamantly. Damn his super hearing.

"Everyone needs friends," I said honestly. I felt the car stop. I looked and noticed my house a bit down the road.

"I'm not dropping you by your house, it will seem suspicious," he said. I nodded.

"Thanks," I told him and he just looked straight ahead and nodded.

"No really, thanks for saving my life," I said gratefully. He might be broody and arrogant but he did save me and I wouldn't admit it but I do owe him. He seemed shocked at the gratitude and seemed like he didn't know how to respond to it. Seems like he didn't get much of that often and once again I felt myself feeling sorry for him.

I got out of the car and began walking to my house.

"Hey," I heard Stefan say out of nowhere and I turned around to see him standing next to Derek's car.

"We're watching you," he said with a friendly smile.

"Yay," I said to them and then turned around.

"Not freaking creepy at all," I said to myself but then remembered they probably heard me. How would I ever say anything anymore without them knowing?

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

"What the hell are you doing here?" Derek asked Stefan even more irritated.

"You think I'd let you have all the fun of eavesdropping?" Stefan asked him.

Derek glared at him.

"Can I sit in your car?" Stefan asked.

"Like hell I'll let someone like you sit in my car," Derek said angrily.

"Fine, I'll just stand out here for now then," Stefan said knowing it would irritate Derek.

"How do people stand you?" Derek asked him annoyed.

"Funny, they say the same about you," Stefan said with a smirk.

NOTE: It will swap between Aria,Scott and Stiles and then Derek and Stefan. Think about like a tv show where they constantly swap scenes. I'll put Derek and Stefan's scenes in bold to make it easier to read :) Let me know if it was too complicated and I'll avoid writing like this in the future :)

I walked up the stairs to my house. I braced myself expecting my father to either be relived and smother me or scold the crap out of me. Either way it seemed like I would not be allowed to leave the house. Before I could knock on the door it already opened.

"Aria!" Scott said relieved as he hugged me, " I thought Derek might have killed you!"

Stefan chuckled and Derek glared at him.

"Jeez, everyone thinks you're a killer, maybe you should smile more," Stefna told him.

"Maybe if you don't shut up soon, I'll prove everyone right," Derek said annoyed.

"Why would you think that? You sent me with him remember?" I asked him, "I was so worried about you guys," relieved they were okay.

"I know but-," Scott began saying.

"But Scott is an idiot and didn't think about the fact that Derek could be a serial killer and you know just kill you," Stiles said coming to hug me.

"Stiles! You're alive!" I said happily.

"Yeah, last time I checked I am in fact alive," he said, "Wait Aria are you okay?" he asked seeing the blood all over my clothes.

"Yeah I'm fine now. Look I know he looks like a serial killer but he actually helped me," I said.

"Derek? Broody, moody, glaring, unhappy Derek?" Stiles asked as we nodded.

"Really nailing your description there huh?" Stefan mocked Derek.

"I'd like to nail you to a wall right now," Derek said wanting to kill Stefan.

"Whoa, whoa, let's not rush this relationship okay?" Stefan said mocking Derek's meaning of nailing. Derek couldn't take it. He got out of the car and stood face to face with Stefan.

"Give me one good reason I shouldn't punch the crap out of you," Derek said.

Stefan folded his arms across his chest.

"We have a deal remember?" he said and Derek was regretting letting him ever live.

"Aria what the hell happened?" Stiles asked, "Actually how are you walking? Weren't you hurt pretty bad? Like almost dying type of hurt?"

"Um, well," I said not knowing how I would explain this to them. I decided the best way was to just cut to the chase.

"Okay here's what I remember. There was some huge animal at the station and I tried to outrun it but it managed to attack me in my back," I said, "I have a vague memory after that. I think Scott and Derek came to fight the animal-," I said but Stiles interrupted me.

"Derek fought that thing?" Stiles asked with his eyes wide.

"I told you that," Scott said.

"Yeah but I didn't believe you," Stiles said while Scott looked at him shocked.

"How could he fight that thing?" Stiles asked.

"Didn't Scott tell you?" I asked him but his face told me no, "Derek is a werewolf."

"She told them!" Derek said angrily, "How could she?!"

"Well at least they don't know about me," Stefan said smirking.

"What?" Stiles said not believing it.

"Yeah, that's how we tried to fight that other thing off," Scott said.

"You know that really puts the whole lone wolf line in perspective," Stiles said now thinking it made sense.

"Yeah well not only that, we were right about Stefan," I said, "He's a vampire."

"Looks like they know about you too now," Derek said finally smirking at Stefan's shocked face.

"I thought she wouldn't tell," Stefan said also irritated.

"Why? Why would she tell them about me and not you?" Derek asked, "You think she treats you differently?"

"Well she did like me," Stefan said a bit smug.

"Please, if she did there is no way she does now. Who the hell can like let alone love a blood drinking creature?" Derek asked.

"You mean compared to a snarling unattractive werewolf?" Stefan said back.

"What?" Scott said now in shock.

"Knew it!" Stiles said at the same time.

"Scott you're a werewolf, how is that more shocking?" Stiles asked.

"Look, I'm only telling you guys because I trust you. We can't tell anyone else," I told them as they nodded.

"I'm serious, otherwise I'm dead," I said and then realised the irony, "I mean I'll be dead for real."

"At least she knows we'll kill her," Derek said.

"Well if it's just the three of them it's fine," Stefan said.

"Okay but if Derek is a werewolf and Stefan is a vampire then how do we know they didn't kill the other people?" Scott asked.

"They didn't, I asked them," I said and they looked at me dumbfounded, "Look just trust me it's not them."

"Really Aria? One is a werewolf and one is a vampire!" Stiles said but I heard the undertone of glee in his voice.

"Scott's a werewolf but he's not killing people," I said.

"Look, just because someone is a supernatural creature doesn't mean they're naturally evil okay?" I said.

"Wonder who she's talking about," Stefan said sarcastically to Derek.

"You sound like you're speaking from experience," Stiles questioned.

"I could have died but they both helped save me, that's the only reason I'm walking now," I said.

"She said both idiot," Derek said back.

"But what if they have another agenda?" Stiles asked.

"I have thought of that," I said thinking back to my reasoning, "The only thing I can come up with is that they're scared of me."

"Scared of you?" Scott asked almost laughing.

"Well the knives I have," I said and then I felt a huge pit in my stomach. What had happened to my bag after I was attacked? What if Derek took them? Or worst Aiden? If the police found them they would keep the weapons for sure.

"What knives does she have?" Stefan asked.

"The ones that kill all people like us," Derek said.

"You sure?" Stefan asked worried.

"Yeah I saw them," Derek said seriously.

"I thought they were destroyed," Stefan said, "You sure they aren't replicas?"

"I'm not sure," Derek said and they both shared the same fear.

"Oh that reminds me," Scott said, "Here," he said handing me the bag.

I breathed a huge sigh of relief.

"I almost freaked out," I told him.

"It was your last words before you passed out," he said.

"Why are they scared of you again?" Stiles asked.

"These knives," I said referring to the bag, "I think it can kill them."

"You really think so?" Scott asked.

"Not just that, I don't think they can touch them," I said.

"Well why don't you test that theory?" Stiles asked and I looked at him confused.

"Use Scott, duh," he said as if it's obvious. I looked at Scott.

"It won't kill me right?" he asked a bit skeptical.

"It shouldn't," I said as he nodded.

"Okay," he said hesitantly. I took one knife out of the bag.

"Okay, just touch it," Stiles said excitedly. We all watched as Scott hovered his hand over the knife. We all held our breath as he touched the knife but nothing happened. We all looked at each other confused. Scott even tried wrapping his hand around the knife.

"Well, that was eventful," Stiles said.

"Well that's good news, seems they are just replicas," Stefan said feeling relieved, "Maybe you didn't see them properly.

"No trust me," Derek said.

"Wait," I said having an idea. I took out the other knife, "Touch this one."

"Okay," Scott said more relaxed but the second he touched it he was in pain. He dropped to the ground.

"Scott you okay?!" Stiles asked worriedly.

"Yeah, I'm fine," Scott said standing up slowly as the pain subsided.

"I told you," Derek said.

"These knives," I said, "Maybe each knife is for a specific creature."

"So this one," I said referring to the one in my hand, "Can probably kill werewolves right?"

"Seems to be," Stiles said, "What about that other one?"

"Vampires?" I assumed.

"I guess it would make sense," Stiles said.

"You know what this means right?" Stefan said worriedly, "She can kill us, all of us."

"I know," Derek said, "I don't think we have a choice."

"We should give her a chance," Stefan said. Derek sighed.

"Fine but if she turns full on hunter," Derek said.

"Yeah I know," Stefan said sadly, "We'll have to kill her."
