Okay this is my crossover fic that I promised. Some of you guys wanted me to let the characters from my stories to intermingle. And let's pretend that Beacon Hills is in South Carolina and not California. Both sides are slightly canon.

[Disclaimer: I do not own Teen Wolf or The Vampire Diaries. I just own my two awesome characters!]

Natural Enemies

Part One: When Good Things Go Bad

Ellie's POV

Tonight I was finally going to be able to have a girl's night. My friend from camp, Persephone (I call her Cookie) was coming down from virginia to get away for a bit.

"So are you sure it's okay, dad?" I asked my dad, who was pouring himself a cup of coffee.

"Yeah, it's fine. Just don't stay up too long." I rolled my eyes. He always says the same thing. Just in time, my brother walks into the room, with his car keys. "Where are you going?"

"To Scott's." He gave me a pointed look. "You coming?"

I looked at him weirdly before answering. "Yeah." I followed him out the door, hearing my dad telling us to be home at a decent time. When we got in the car, I had to see what was going on. "What's going on?"

"Tonight's the full moon." I gasped. Holy shit, I forgot.

Stiles saw my face, "Oh my- what did you do?"

"You remember my friend from camp?"

He nodded, "Yeah. Why?"

"She'll be here tonight."

"Are you serious?" My brother shouted. "The full moon's tonight. We don't need anyone else around!"

"Sorry! I forgot! I needed a release. I haven't exactly had a day off, y'know." I justified my own stupidity.

"You were supposed to watch Derek!" Damn, I forgot. "What do we do now?"

"I'm thinking..." I can't run back and forth to his house without Seph noticing, and I definitely can't take her to Derek's house. The hypothetical light bulb went off in my head. "I got it! I'll keep Derek in the basement while Seph stays in my room. The door is reinforced, dad's tools are back there, the old chair-"

Stiles caught on, "Ok, but we have to be careful."

"It'll be fine. Dad won't be home until midnight, and you know that I'm good at distracting people." I reassured him.

"Call Derek. You deal with him, since he has a soft spot for you anyway." He smirked at me. I narrowed my eyes, shoving him. He gasped in fright, "You don't shove the driver! You trying to get us killed?"

I rolled my eyes, "Quit whining and drive, you dork."

Persephone's POV

"Bonnie, don't worry about me. If anything, I should be worried about you. I just think it would be easier if I stayed with some normal people. I need to keep my sanity a little bit, before I go nuts."

"I know, I'm just going to miss you. That's all." Bonnie told me through the phone.

"Aww! I'm going to miss you too, twin." My phone was beeping for another call. It was Elena. "Bonnie, I'll call you back tonight. Elena's beeping in."

"Okay, you better. Bye."

I answered Elena's call.

"Hey. I heard that you left Mystic Falls this morning."

"News travels fast. Yeah, I'm just staying with a friend for a couple of weeks."

"Wow, I'm a bit jealous. But you deserve it, to be around normal people, with all that's going on."

"Yeah, I do need this. But home is home, no matter what. And I will be back soon."

"Good, because I'm going to miss you."

I smiled, "I'm going to miss you too, Lena."

"Seph, did you talk to Damon yet?"

Oh no, here we go... "I left him a voicemail this morning."

I heard her sigh, "Seph, you know how he is. Didn't you owe him a face-to-face at least?" I swear she scolds me like she's my mom.

"Not really. Don't you remember what he put me through?"

"Two wrongs don't make a right, Seph."

"Well I can't do anything now."

"Yes you can, call him right now."

"Fine, whatever."

"You'd better call."

"I will, I will. Tell Care, Matt, and Ty that I love them!"

"Sure. I want a phone call every once and awhile."

I smiled, rolling my eyes, "Sure, Lena. Bye."

"Bye, Seph. Have Fun!" And she hung up. Yeah, I'll call Damon later. I neared a sign that read, Welcome to Beacon Hills. I immediately smiled and called Ellie.

"Yellow."

"Green. I'm officially in Beacon Hills."

"Cool! You know the street right?"

I nodded, before remembering that she couldn't see. "Yeah, 1439 Sycamore St, right?"

"Yeah. It's past the Shell gas station, where you make a left, and two rights. I'm not going to be there, so make yourself comfortable."

I groaned, "Aww, Ellie, you're leaving me in your house by myself?"

"Hell yeah! I have to get us some snacks. I forgot your chocolate covered pretzels."

I gasped, "You bitch! You forgot the most delicious snack I had ever tasted in my life?"

I could tell that she was rolling her eyes, "I'm going to get it now. Don't get your panties in a bunch. I'll see you in a bit."

"Okay, bye." I said, with attitude.

"Brat..." I heard her mutter.

"I heard that!" I gasped.

"Good." And then she hung up. I turned onto her street, and finally parking in the driveway.
I got out of my car and popped the hood, pulling out my eight pound luggage. Damn, what did I put in here?

Elllie's POV

I just walked into Derek's house as usual and called for him "Derek?"

No answer.

"You know I have zero tolerance for this." I muttered.

"You're early." I gasped, hearing Derek's voice from behind me.

"Not really, there's been a change of plans." I carefully told him. "We're going to have to move this to my basement."

"Why?" I looked at the ground. "You did something." He stated.

"Kinda." I took a deep breath. " I invited my friend over a while ago, forgot about it." I waited for the anger, hell I deserved it. This time, I can admit that I did some stupid shit. I can't get anyone involved in this!

"What is it with you and your brother doing stupid shit?!" He shouted, causing me to wince at his loud voice.

"Hey!" I heard my brother shout from the car. Derek and I shot glares in his direction, causing him to look away. Yeah, it's that intense.

"So you must have a solution?" He seemed to have calmed down a bit, but his teeth were still clenched.

"Yeah! I was...uh...getting to that." I said nervously. I knew that this was brought on by the full moon, but I was still a bit nervous. "My basement is perfect. It used to be a jail cell back in the 1800's before the metal was broken down."

He nodded. "Okay. I'll call when I get there."

"Er...um okay." I turned around and quickly went back to the jeep. My brother was looking at me for some odd reason. "Are you curious about our genealogy or do you just like our face?" I asked snarkily.

He turned away, stepping on the gas. "What's got you so bitchy?"

I rolled my eyes, "I don't like to admit that I'm wrong. But I did, and it sucks." I heard him mutter something about it being my time of day. "What was that?"

"Nothing." That's what I thought.

-XxxX-

"So we need something to sip on..." I read my list of must-haves aloud to my dear twin.

"Can't Allison help you?" He whined.

"Well Allison's not next to me right now, is she?" I quipped.

"Well call her, 'cause I have to be at Scott's to set up his room."

"Ugh, you whine too much." I grabbed a bottle of apple cider and loaded it into our cart. "Okay, that's it."

I wandered to the front of the store. To my surprise, there was a line of about thirty people for the one cashier that was working. "Are you kidding me?! This town is no bigger than a bottle cap on the map! How in the hell is there this many people on line?" I fumed.

"What are you-gah!" My brother said, coming out of the same aisle that I did. "How is this possible?"

"I know right?" I glanced down the hallway and saw the one thing that might save me from going ape-shit.

The nice, lonely, unattended intercom down the aisle. My lips quirked upward into a giant grin. "Stay here, bro." I sauntered down, past all of the aisles, making sure that no one was watching. When I made it there, I pressed the intercom button.

"ATTENTION SHOPPERS," My voice echoed, "DUE TO THE CONGESTED LINES IN THE FRONT OF THE STORE, THE PHARMACY IS NOW TAKING CUSTOMERS." I smiled as I noticed almost all of the people charge toward the back.

I met eyes with my twin who mouthed, 'You're awesome.' I took a bow and quickly got out of there before they had noticed who did it. We were up next, followed by the disappointed people behind us.

I resisted the urge to laugh evilly.

-XxxX-

When I got home, I heard the stereo blaring. No doubt, from my room. The song choice was quite obvious. When I entered the room, I spotted my caramel skinned friend dancing around with a scarf on her head.

I grinned, "Did you miss me, Cookie?"

When she turned around, she screamed, "Cream!" And right then, I was squeezed by a fairly taller and petite oompa loompa.

Persephone's POV

I pulled away, "How have you been?"

Her expression falters a bit, "Busy. Very busy." I honestly doubt that she's as busy as I have been.

"Me too." My secret smile when I think about Damon gives me away.

"Ah, there's a guy." Ellie sang, with a smug look. Damn this girl is good.

I sighed, "Yeah."

"Seems complicated."

I furrowed my brows, and I thought I was the psychic one. "Yeah."

She sat up on her bed and patted the spot next to her, "Tell me about him." I sat next to her and thought of what to say.

"His name is Damon. He's older, narcissistic, selfish, an asshole, and sometimes insensitive." I started, "But he can be sweet, loving, caring, and dependable."

Ellie was smirking the whole time. "Is he hot?"

I bursted into a fit of laughter, "Is that all you care about?"

She waved me off, "Pssh, no..." She smirked again, "Maybe. So is he?"

I nodded, "Too hot for words."

"You are soo in love with him." She sang, laying back on the bed.

"It's super obvious, isn't it?"

"Yes it is, my friend." I glanced at her, she looked like she was in lala land.

I smirked, "So who's your guy?"

"What makes you think that I have a guy?" She denied.

I rolled my eyes, "The faraway look in your eyes when I was talking about mine. So spill, before I go all crouching tiger, hidden dragon on you."

She snorted, "You are not a ninja."

I had a smug look on my face, "I'm a cheerleader, so I could definitely move like one."

She stared at me for a while to see if I was bluffing, before rolling her eyes, "If you must know, his name is Derek. He's older too, and a bit mysterious." I ooh'd. "He's determined, he likes to take charge, smartass, good sense of humor, too serious, a bit of a martyr, hates to care about people, but does anyway. And has the best ass that I have seen in years." Sounds like a mix between self-loathing Stefan and ripper Stefan.

I laughed, "And just for a second, I thought you were deep!" She joined me in my fits of laughter.

We sobered up, "But yeah, that's him."

We both jumped up and chorused, "Twenty questions!"

"Wait a second! We need food!" Ellie jumped up and ran down the stairs. I thought this would be the perfect time to call Damon.

I took a deep breath while I waited for Damon to pick up, "A phone call, aren't I lucky?"

"Sorry, I thought it was best that not many people knew I was leaving. I knew that Elijah was looking for me..."

"When were you going to tell me this?!" Damon hissed into the phone.

I rolled my eyes, "Because you get all over-protective. I'm fine. I'm at a friends house."

"Althea is coming for you."

"What?" I panicked.

"Where are you?" He asked me.

"I'm in South Carolina. Beacon Hills."

"Stay there. We're coming."

"What? Who's coming?!" He didn't mean all of them, could he? And he hung up. I was about to call Bonnie, when Ellie rushed into the room, arms filled with junk food. I immediately felt really guilty. I was possibly bringing my mess to her quiet little town.

"Okay, here's your pretzels!" She tossed them to me and I mumbled my thanks. "What's the problem? Did I buy the wrong brand?"

I shook my head, "No, I'm fine." It's funny that she's pretending to care whether she brought the wrong brand of pretzels.

She punched my shoulder lightly, "Save the sad look for when we watch breaking dawn part two."

I smiled, "You have it!"

She grinned proudly, "Yup, I'm that awesome. Let's get to this game!"

I thought of a question, "Does your guy wear boxers or briefs?"

She tapped her chin, "Sadly, I have not been in his underwear drawer...yet." She wiggled her eyebrows at me. I laughed at her. "You?"

I recalled a time that Damon was almost naked. "Definitely boxer briefs."

"Ooh..." She sang.

Ellie's POV

While Seph was on the phone

I got a call from Derek while I was in the kitchen, "Hello?"

"I'm outside."

"Come through the back door. It's unlocked." I said, hanging up the phone. I stretched toward the peanut butter, but couldn't reach it.

I was startled by a strong arm reaching above me. When I turned around, I realized that it was just Derek. "Thanks." I gestured for him to follow me. "This way."

He followed me to the basement and down the stairs. I showed him the old cell. "Grab the wolfsbane out of my bag." I obliged, grabbing the plant out of the bag. When I turned around, he was taking his shirt off. "Whoa..." I said to myself. "Er...um, here."

"Fix these chains." I tied the chains around the ring and clamped the both cuffs on Derek's wrists. Then I tied his feet, before checking my work. "Is it tight enough?"

"It's fine." He reassured me. "I'll be fine."

"Okay, I'll be back in an hour to check on you." I went upstairs and grabbed the junk food, running back up to my room.

"Okay, here's your chocolate-covered pretzels!" I said tossing them to her and hearing her mumbled thanks. She looked a bit upset? "What's the problem? Did I buy the wrong brand?" Not that I cared. I'm not taking those back.

She shook my head, "No, I'm fine."

I wasn't too convinced, but I decided to let it go. I punched her shoulder lightly, "Save the sad look for when we watch breaking dawn part two." Bought it last week for this exact reason.

Her eyes lit up, "You have it?!"

I grinned proudly, "Yup, I'm that awesome. Let's get to this game!"

She thought of a question, "Does your guy wear boxers or briefs?" I thought about if I had ever seen Derek in underwear. No...not really...

I tapped my chin, "Sadly, I have not been in his underwear drawer...yet." I wiggled my eyebrows at her. She laughed at me. "You?"

She looked thoughtful. "Definitely boxer briefs." I was wondering if there was a story behind her expression.

Seph told me that she wasn't a virgin, since she lost her virginity the summer to her ex-boyfriend before she came to see me last. I'm not surprised though, she's gorgeous, awesome, and a cheerleader. Plus, the guys in her school aren't tools, douchebags, or jackasses.

"Ooh..." I sang. "Okay, have you had ever a naughty dream before?"

"Of course! Who doesn't?"

"You're right. Okay do-over." I thought of another question. I heard a loud bang down the stairs. "What the hell was that?" Please don't be Derek. "I'm going to check it out." I stood up and neared the door.

"You want me to come with you?" I heard Seph call, which made me turn around.

"No!" I said quickly. "I mean, stay up here. It could be my stupid brother or something." She looked at me weirdly, before sitting back on the bed.

I dashed down the stairs, making a beeline for the basement. I unlocked the door and raced down the stairs to see Derek on his knees, breathing heavily. I walked up to him carefully, and placed a hand on his shoulder.

He instinctively pushed me back, causing me to fall onto some tools. I felt something sharp pierce my back, but it didn't hurt that much. "Sorry." He told me, helping me up.

"I'm okay, I guess." I looked him over. "Are you okay? I heard you from upstairs."

"I'm fine now. I just lost control for a second." I heard the doorbell ring. "I'll be right back." I rushed up the stairs to see that Seph had already answered the door. I came up behind her to see who was there.

It was a girl...who looked exactly like Seph.

"Who the hell is this?" I asked.

That is the end of part one! I hope you like it and stay tuned for part two! Review Please! I want to know if you like it!
