A/N: Hey readers! Hope you enjoy.

It was a rather cliché move, the curly haired demon could admit, but it fit her style. Katherine Pierce was sneaky, cunning, and in order to facilitate these traits, certain precautions needed to be met. For one, it was the middle of the night. Katherine was perfectly safe under the cover of darkness; it was she who got to pick whether or not someone would see her.

"Miss Gilbert," a short, plump woman at the front desk called to the vampire, "visiting hours are over. Come back in the morning and then you can see your friend." Katherine smirked slightly, withholding from rolling her eyes. As if this puny human could control anything she did. She nearly scoffed at the thought.

"I'll just be a minute," Katherine simpered coolly, "You'll forget I was here once I leave." The woman repeated the words dully in a trance. Compulsion had its perks, and Katherine wasn't afraid to exploit every single one of them.

For a reason unbeknownst to her, Katherine found herself slowing down before she reached the hospital room of her intended target. Was there really a point of doing this now? There were so many other people to choose from, and so many other dramatic fashions that would just as easily piss off the Salvatores. So what made this blonde so special?

That's easy. Katherine liked the poetry that came along with choosing this particular person. It caused amusement to spark like a fuse within her. Her smirk was positively wicked illuminated by the pallid moonlight. The brunette forged on.

She was exactly the type of vampire to do a maneuver like this one—absolutely positively cruel.

Katherine walked purposefully into the stuffy hospital room, closing the curtain around them to give her, and a peacefully unaware Caroline, more privacy. A stray security camera would be no help in a situation like this. She could compel all the people she wanted, but if someone had digital evidence of a crime committed, that was much harder to erase.

Katherine tutted as she looked down at Caroline, Elena's, her doppelganger's, best friend. Such a tragedy. . . a complete waste of a pretty face.

To think that this could've been avoided too. But her boys just weren't going to listen to her, so she'd teach them a lesson for their asinine defiance.

No one messed with Katherine Pierce and got off scotch free.

The doppelganger smirked down at the helpless girl in her hospital gown, seemingly sleeping without a care in the world. Oh, it'd be her pleasure to disrupt that all right. She'd been forced to play it cool the last few days so that she did not draw attention to herself, more specifically, the Salvatore's attention. Now, she could exact her revenge, and Katherine was brimming with giddiness beneath the collected mask.

Without conscious thought, the brunette's eyes raked over Caroline's form; she was beautiful. It was almost a shame that she had to die. As Katherine's eyes skimmed over the blonde's wrist, she noticed something peeking out from beneath the tasteless gown that the nurses had dressed her in. Raising an eyebrow, Katherine slid the material aside with deft fingers to get a better glimpse.

It appeared to be a tattoo, but Katherine knew that it wasn't as simple as that. She could feel that there was something . . . supernatural about it. A peculiar energy seemed to radiate from it. The stranger part being that Katherine could physically feel it. That's never happened before.

Katherine was quick to discern that she was looking at Caroline's soulmark. She raised an eyebrow as she appraised the mark.

It was a peculiar sight to see one on a human.

The phenomenon was rare, but it did happen. It usually had something to do with the fact that her mate was already alive, and as she was born, she herself gained their mark as well. It's said that the marks call to one another when in the near vicinity to each other; this made it possible for the supernatural creature to ascertain their soulmate out of the human population.

So lost in her thoughts, Katherine failed to realize just why the mark was so dauntingly familiar. Resentment and anger exploded in her gut. What the hell?

Katherine growled aloud, eyes narrowing into slits. Caroline's mark was the very same one that rested on the back of her left shoulder; she was the blonde's soulmate. Well that's fucking great. Perfect timing, as usual. Katherine's own thoughts mocked her, and for the first time in decades, she was overridden by emotion.

Caroline woke as Katherine's rage reached its peak. Damnit. There was a time where she would've jumped for joy at this discovery, but she'd long since given up on finding her soulmate. Katherine had changed. She no longer looked upon the world with rose tinted glass and with innocence. Hardship had molded her into the person she was today, and that person wasn't going to fall over and accept this situation so easily. There was way too much going on in her life now. She didn't have time for a soulmate. Besides, right now, it was all about revenge.

The Salvatores need to pay. With this in mind, the brunette pushed away all feeling.

"Hello Caroline," Katherine grinned wickedly, "I need you to deliver a message to the Salvatores for me."

"What?" Caroline's eyebrows furrowed as she groggily wiped her eyes. "Elena?" The blonde's voice was so sweet. It was like music to Katherine's ears. She yearned to hear it again. Damnit, Katherine cursed again. She can't think like that.

Katherine tilted her head to the side, gazing down at Caroline calculativedly. "My name is Katherine. As for the Salvatores," Katherine paused, hesitant to go in for the kill, "Game on."

Just do it already.

With that, Katherine snatched a pillow off the bed and pushed the pillow with her vampiric strength into Caroline's face, effectively suffocating the blonde. She watched numbly as Caroline struggled. Minutes passed and Katherine nearly let go of the blonde when an unbelievable feeling pooled in her gut. Eventually, Caroline fell limp, succumbing to her death.

Katherine ignored the mind-numbing pain that flared in her mark and strut out of the hospital, all the while ignoring the emotions that tried to push their way to the surface.

She would be seeing Caroline again.

The mantra keeping all the pain at bay played in her head over and over in a loop as she exited the hospital. I shall see her again.

Soon.

That was interesting to write. I can't say I've ever done this pairing before! It was refreshing though to try on a new pair. That sounded like I was referring to clothing, lol. Ah well, you know what I meant.

Oh, and did I get Caroline x Katherine's ship name right? I think I randomly made it up after I finished writing this piece. Tell me what you think. Until next Friday peeps.
