Elena's POV
She was clearly taken by surprise, and for a minute, I'm not sure that she would kiss back, but then her hands were in my hair and I found myself pulled closer towards in, nearly into her lap.

I smiled against her lips, and pulled away just for a moment so I could see her face.

She looked at me from beneath her eyelashes, and I finally saw the Katherine I knew and loved as her lips curved into that classic smirk and she grabbed my arms, pulling me closer and kissing me again, and I almost couldn't get over the fact that I was sitting on my hallway floor making out with Katherine Pierce.

But just as the kiss deepened and Katherine had started grabbing at my shirt, I could hear the distant sound of the doorbell ringing.

Sighing, I pulled myself off of Katherine and onto the floor beside her. We were both breathing heavily.

"Just ignore it." Katherine said breathlessly, reaching towards me again.

I pushed her off of me and stooge smoothing my slightly wrinkled shirt.

"It's impolite." I replied as I made my way downstairs.

I could hear her laugh as I walked over to the door. I knew exactly what she was thinking. Even as a vampire, Elena never changes.

I opened the door and immediately panicked. Damon and Stefan stood at the door looking extremely worried.

"God, guys, I'm sorry!" I said, mentally slapping myself.

Of course, I had forgotten to tell them that I wasn't sleeping at the Salvatore house for the night. They must have woken up and found me gone and assumed the worst.

"Why did you come home?" Stefan asked, looking around me to the inside of the house, as if he expected to see some guy there.

If only he knew just who was here.

I shook my head, desperately trying to come up with an excuse.

"Uh, I guess I wanted to just be home. I felt more, uh, comfortable here. And I just forgot to tell you. I'm so sorry." I giggled nervously, knowing that Katherine was listening to my every word upstairs.

They seemed fine with my answer, but their faces remained grave.

"What's wrong?" I asked, reading the obvious worry in their faces.

The brothers exchanged glances.

"We didn't want to tell you so soon, right after you turned your humanity back on, but we don't want you to be caught unawares." Stefan started slowly, again exchanging a glance with Damon by his side.

Instead of letting Stefan continue, Damon rolled his eyes and cut into Stefan's slow paced wording.

"There's a new evil that's coming to Mystic Falls."

Stefan glared at him, but Damon kept a close eye on my reaction.

I couldn't say I was surprised. New evil came to Mystic Falls all the time. The place was practically crawling with supernatural evil.

"So? We just get together everyone and find a way to kill the thing. Simple."

"Careful, they can see your Katherine coming through." said a soft voice behind me, and I whirled around before realizing that Katherine had tapped into my new vampire hearing to talk to me.

I turned back around to face the Salvatores.

"Sorry, thought I heard something. But that's all we do, right? We've done it a ton."

"It's more than just that this time." Stefan said.

I raised my eyebrows. We had gone through strange sacrificial ceremonies, evil, original vampires, and un-killable doppelgängers. What hadn't we faced that we couldn't conquer?

"What is it?" I asked, crossing my arms across my chest.

"We're not exactly sure." Damon said, shrugging.

"Then how do you know that this is different than anything we've faced?"

Stefan dove into the explanation and I listened intently to it, trying to digest as much information as I could.

"While you had your humanity off, Bonnie did a spell like she usually does to recognize any possible new supernatural energy in the area. And she found a disturbance in the normal energy of the town, one she's never felt before. She saw an image and we were able to look in our library for what she saw."

"And?" I was staring to get nervous, and I began to wish Katherine was there, comforting me.

"The image she saw, we found it in several old journals, from ancestors. It's a demon, and no one has ever really seen it, just a shadow of it. Every time, it seems like these evil shadows had no shape, much like black smoke, and had bright glowing. From what ancestors have written, it seems like this thing shows up every one hundred years in Mystic Falls."

"And what the hell does it do? What makes it so terrifying?"

Stefan and Damon exchanged yet another glance, and then Stefan began speaking quietly.

"From what people have recorded, the demon comes upon you, and turns you into a mindless killing machine."

"What?"

They were right. This was unlike anything we had ever faced.

"You don't think, you don't even seem to have a mind anymore. Your only purpose is to kill. Anyone and anything."

I closed my eyes, having difficulty taking everything in.

"And... What's the cure? For this killing thing?"

"There's no cure." Damon said bitterly.

"We assume the only way to stop the taking over the minds is by killing the demon, but people have tried, and everyone has failed. So these people stay mindless killing drones forever."

Stefan must have noticed the fear in my eyes, because he placed a hand on my shoulder in an act of comfort.

"We're going to find a way to destroy this thing, Elena. We always do. Just be careful until we do, okay?"

I nodded.

"I'm going help to try and kill this thing. I'm not just a puny human anymore. I can finally help."

They looked reluctant, but they both agreed.

As they went on their way, I immediately closed the door and raced upstairs.

Katherine was sitting on the floor where I had left her. She didn't look up when I arrived upstairs.

"I guess you heard everything." I said to her.

She looked up at me, and again, Katherine Pierce was gone, replaced by a pale-faced, shaking stranger.

"Elena, I've seen this thing before." she said, her voice trembling.

I sat beside her, gripping her hand, urging her to go on.

"I've seen it happen every one hundred years that I've been in Mystic Falls. This... demon doesn't care if you're a human or a vampire or a witch. It will come after you and make you into something that will murder everything in its path. Please, don't help them. I can't let that happen to you."

Tears began running down Katherine's face and she turned fully to me.

I took her face in my hands, leaning in close to her so our lips were almost touching.

"I have to help, Katherine. It's what we do. All of us."

She didn't respond, but put her arms around me instead, holding me close.

I could tell she was still crying from the way she was shaking. I kissed the top of her head and embraced her.

I wanted to spend every minute loving her. I didn't know what would come in the future.

Hey! Sorry I haven't updated in three million years! I was just on a trip and then I had to decide what to write for this chapter. And then I actually read the description that I wrote for this book and watched an episode of Buffy, and boom! Inspiration! Hope you enjoyed this chapter.
