Rebekah was up to something, a notion they could all agree on. Elijah, Hayley and Y/N sat on the couch in the living room of the Mansion, not hearing a sound despite knowing she was home. The one person who wasnât present, was Klaus.
Thus, Rebekah was definitely up to something, but what it could be?
Lots of possibilities, with many different levels of peril, all designed specifically for one Niklaus Mikaelson. They knew they should probably get involved, especially Y/N, whose very boyfriend was the one at risk. But they also knew the outcome would be spectacular, so they all silently decided to do nothing. For now, Y/N would continue to write on her computer, and Hayley and Elijah would continue reading the same book together.
It may be a national holiday, but they had other things that required their attention at the moment.
A loud crash came from above them, followed by a curse only heard by the ones with supernatural hearing. They all looked up to the ceiling, right where they knew that Klaus and Y/Nâs room was located. Simultaneously, they looked back to each other, one more silent conversation later, and they returned to their activities.
Hayley felt a buzz against her hip, and she knew it was Elijahâs. She reached between them to grab the phone, opening the notification.
âKlaus just texted saying he was on his way, based on the colorful vocabulary, Iâd say the negotiation with Marcel didnât go as planned,â Hayley said quietly to the group, not loud enough for Rebekah to hear as she showed the text to Elijah.
âHe said heâll be here in a few minutes. I wonder, should we tell her of her expedited deadline?â He muttered, thumbs poised working as he replied to his brother.
âHell no,â Y/N laughed, and soon as it happened, the three paused, making sure Rebekah wasnât listening into the conversation now. When nothing was heard yet, they all let out a collective breath.
âI want to see this play out, without interferenceâ She said, softer this time as a wicked smirk came upon all of their faces.
âA scientific experiment, if you will,â Hayley said, suppressing the urge to laugh.
âYes, for science.â Elijah said, and without another word, they all resumed what they were doing moments ago.
As promised, minutes later, Hayley and Elijah heard the faint hum of Niklausâs vehicle. Apparently, Rebekah did as well, judging by the way they all heard another curse, followed by a frantic shuffling, and then she ran down the stairs and into the foyer.
She was slightly out of breath, and her eyes looked wild. The most damning piece of evidence was the lone feather sitting in her hair.
It didnât take a conversation to know they would keep that information to themselves. Letting the cards fall where they may, in the name of knowledge. Rebekah smoothed out her shirt, letting out a breath as she walked over to sit next to Y/N on the adjoining couch. She picked up a random book as the car drew closer.
âI hope that I can trust you all to agree that I was here the whole time,â Rebekah said sweetly, an underlying threat laced in her words as she kept her gaze on the book.
âAs long as my room isnât destroyed,â Y/N said just as sweetly, and Rebekah paled slightly. Y/N may still be human, but she was still able to make Rebekah gulp.
âRebekahâŠâ She began to warn, right as they heard Klaus make it to the driveway. Only moments now.
âI will fix it myself but please say nothing,â She whispered, speaking fast, pleadingly, and before Y/N could agree or deny, Klaus sped into the mansion. His posture was tense, and his brow was furrowed. They all knew Hayleyâs suspicion was correct.
âMarcellus Gerard is a conniving twit and I will be glad when we finally dethrone the treacherous bastard,â He huffed, as his gaze shifted to his girlfriend, and he softened in front of their eyes. He plopped down behind her, pulling her body closer to his chest. His hands traced down her arms as he whispered loud enough for only her to hear. Not that any of them would want to hear whatever it was. Based on their facial expressions, it wasnât hard to guess what was being said.
âI rather think a long relaxing wash in my multi-headed shower sounds rather spectacular before the upcoming night of festivitiesâ Klaus grinned into her skin. She shivered as she felt his warm breath on her neck, and she began to nod her head. But then she opened her eyes and gazed back upon Rebekah, with the damn feather in her hair.
She quickly thought of an excuse.
âIâll be up in a moment, I have a couple more things I need to write down before I forget them.â She said, a little breathy. Both at the thought of what was promised, and her being put on the spot. Then another thought crossed her mind, as Klaus nodded, pressing a kiss to her shoulder.
If she didnât say anything, she would surely not get to experience whatever Klaus was cooking up in his gorgeous head. But if she told him. He might forgive Rebekahâs attempted prank in favor of private time with his girlfriend. She locked eyes with Rebekah, and saw that she knew what Y/N had on the line.
After a tense millisecond, Y/N rolled her eyes, and let Klaus get up without another word. Rebekah breathed out imperceptibly, and Hayley rested her mouth against Elijahâs shoulder to conceal her smile.
Right before he left, Klaus turned and looked at Rebekah.
âThereâs a feather in your hair sister,â He said, before turning back around, as Rebekah frantically pulled the feather from her blonde curls.
Klaus finally left with a pleased smile on his face, and suddenly they all felt a bit guilty.
Only for a moment though, he had staked and tortured (except for Y/N and Hayley of course, though Hayley was not immune to his taunts and quips) them many times over the centuries.
âThanks for telling me,â She growled quietly, and Elijah casually looked up at his sister.
âFor the results to be as accurate as possible, we could not interfereâ He said matter of factly, as Hayley nearly snorted, her hand gripping his button up shirt. He reached up to grab hers, and brought it to his lips.
Before Rebekah had the chance to ask what the hell he was talking about, they collectively heard Klaus open his door, and then a mechanical grinding. Something that sounded like a liquid fell to the floor as Klaus cried out in clear surprise. Moments later, and a loud wooshing sound was heard.
It was silent for a few moments, and everyone waited in bated breaths for what was to come next.
âREBEKAHHH!â Klaus screamed dramatically, and before the name was even finished, she was out of the door, running away like her life depended on it. Probably because it did.
The group busted out laughing, and Hayley and Y/N looked to each other. Another wooshing sound and there he was.
Covered in thick chocolate syrup and a shit ton of feathers stood a murderous Klaus Mikaelson. Even the stoic Elijah couldnât help the chuckle that left his lips at the clever prank.
âFirst, Marcellus turns down a perfectly good exchange of power, then my sister proverbially tars and feathers me, and now I begin to realize that my sweet Y/N let her devoted boyfriend walk right into a trap,â He said, continuing the dramatics as always.
âHappy American Independence Day brotherâ Elijah sighed, as fireworks started up outside. Hayley turned excitedly to the window, and his gaze turned to her, adoration clear on his face. Without another word, he stood up, Hayley cradled in his arms as she yelped at the sudden movement.
âIf youâll excuse us, I will be going to take my partner to watch the fireworks,â And he ran out of the room before Klaus had the chance to argue, Hayleyâs giggle echoing in the wind.
Klaus huffed indignantly, getting himself all worked up again. Y/N lifted the laptop from her lap, setting it to the side so she could make her way to her whining boyfriend.
âIâm going to find Rebekah, and when I do IâllâŠâ He ranted, Y/N wrapping her arms around his neck, not caring about the sticky transfer of chocolate sauce and feathers onto her clothes. His arms wound around her waist as she quietly interrupted his threats.
âPretend to laugh it off, to lull her into a false sense of security. Then youâll come back to me to plan your revenge,â Her lips ghosted over the skin of his neck as she spoke, before her tongue darted up to lick a bit of the dark syrup.
âFor now, I promised you a nice long shower,â She said as she pulled away, and met his signature smirk.
âYou are truly wicked my dear,â He all but growled, pulling her harder against his body as she giggled. âI believe you are correct, I will most definitely be needing your assistance, love,â And as soon as the words left his lips, he picked her up and ran them to the washroom, the need for revenge forgotten for now.
A solid day's work in the name of Science.
