Mischief Night was a tradition that Beacon students took very seriously, consequences or not. The day before Halloween was always filled with laughter and screams as teenagers ran around recklessly, pulling pranks on peers and teachers alike. Many teachers called in sick on October 30th, but never Bobby Finstock.

Every single year, Stiles and Scott would sneak into the school as soon as Mischief Night began and find a different way to make Coach Finstock angry. And every single year they would also beg Harper to come along, however she always declined.

Last night she was shaken awake at ten past twelve to a grinning Scott, telling her that Stiles was about to call any minute and they had to leave. Instead of Harper slipping some clothes on and following him out the door, he earned a pillow to the head and a mouthful of curse words he was sure wouldn't escape the friendly girl during the day time.

That was why it was a surprise when Harper turned up at Stiles' locker the next morning, a bounce in her step and a smile on her face as she greeted them happily.

"Hey guys," the petite brunette chirped, leaning up onto her toes and pressing a kiss to Stiles' jaw.

Stiles grinned down at her, "not that I don't love that smile, but what's got you in such a good mood?"

His hand reached on top of her head, his slender fingers peeling out some confetti from her hair. He inspected it with furrowed brows for a second.

"I got it launched at me as soon as I came through the door," she giggled slightly, running her hands through her curled hair, "I don't know, it's kinda nice to see everyone so happy."

Stiles glanced around at the hallway and realised what she meant. Teenagers were running around and laughing, a huge contrast to the usually dead atmosphere of Beacon Hills High.

Scott raised his eyebrows, "you've never liked Mischief Night. In fact, you've never been so mean to me than this morning when I asked you to come with us," he joked, "I was feeling genuinely insecure."

Harper laughed whole heartedly, a noise that pleased both of her best friends. They loved to see her so happy, for whatever reason it may be. Their lives were pretty bad at the moment, so at least one of them was having a good time. And if it was going to be any of them, both Scott and Stiles believed Harper deserved it the most.

"Sorry," she shrugged, smiling a little.

"Do you think that everybody else being happy is making you happy?" Stiles thought after a while of rummaging through his locker, "like, if everyone was scared, you would be scared too?"

"Maybe," Harper hummed, pursing her lips together as she tried not to think about it, "personally, I don't care. I feel amazing."

"Good," her boyfriend flung his arm over her shoulder, "I am so very glad."

The couple noticed Scott's silence and saw him staring at the lockers across the hall. Harper caught sight of Kira Yukimura shoving some books into her bag and she smirked a little.

"What are you looking at?" Stiles teased as he turned back to his books.

"Me?" Scott snapped out of it.

"You," Stiles nodded, pulling some egg cartons out of his bag and putting them into his locker, "you looking at her?"

"Who her?" The alpha decided to play dumb.

Harper rolled her eyes, "Kira, dummy!"

Scott's eyes widened and he placed his hand over Harper's mouth. Unfortunately, her happy mood meant she was also a little care free, and so her voice was a little louder than intended. Stiles just snorted.

"No!" Scott tried to play it cool as he let go of her face, looking back at Kira to make sure that she wasn't watching, "I mean, she's- she's new. She's cool."

"So, ask her out," Stiles advised carelessly as he zipped his bag and slammed his locker shut, moving in between Harper and Scott as the trio began to walk down the hall.

"Now?" Scott spluttered.

"Yes, now," Stiles spoke as if it was easy, as if he hadn't spent years pining over Harper.

"Right now?"

"Right now!" Stiles repeated, "Scott, I don't think you get it yet. You're an alpha. You're the apex predator. Everyone wants you, you know? You're like the hot girl every guy wants."

They paused in the hallway as Isaac joined them late to the discussion.

"I'm the hot girl?" Was all Isaac heard from Scott.

"You are the hottest girl," Stiles reminded him as he began to walk away, "Come on Harps," he called.

Harper jokingly winked and sent him a 'call me' sign before rushing off to follow her boyfriend.

"I'm the hot girl," Scott repeated, in some sort of trance as he held onto the straps of his backpack.

Isaac smiled, "yes you are."

Scott grinned and chuckled happily, a new confidence in his step as he began to walk away, Isaac staring after him and shaking his head in amusement.

...

"Son of a bitch!" The familiar roar of Coach Finstock echoed from his office as the economics class pulled out their books and put them on their desks, patiently waiting for their teacher to arrive.

Harper shook her head with a small smile as everybody began to chuckle, Scott and Stiles sending each other knowing looks.

"Mischief Night, Devils Night," Finstock snapped, throwing a pencil on the ground as he entered the room, slamming the door behind him, "I don't care what you call it. You little punks are evil."

Harper had no clue what had gone down in the office next door or what Stiles and Scott had done to the poor man, but she couldn't help but giggle along with the rest of the class. Stiles fiddled with the pin between his fingers, a grin on his face.

"You think it's funny every Halloween my house gets egged?" Coach questioned rhetorically as Scott smirked across at the Stilinski boy beside him.

Not only would the two teenagers play a prank on Coach Finstock every Mischief Night, but they would also head over to his house the next day only to egg it, hence all of the cartons building up in Stiles' locker.

"A man's house is supposed to be his castle!" Finstock carried on, smacking his hand down on Scott's death when the werewolf only chuckled louder, "mine's a freaking omlette!"

"Oh this?" The Economics teacher turned to his desk where a gift wrapped box sat neatly in the centre, "we're gonna do this again, huh?"

He picked it up and threw it to the floor before stomping down on it with his big boot. Glass smashing echoed through the room, indicating it hadn't been a prank like he had expected. Stiles grinned wickedly as Coach leant down and picked up half of a smashed mug. It had a picture of himself on it and 'number one coach' written underneath.

"'Happy birthday'," Coach sighed as he read the letter that came with it, "'love Greenberg'."

Everybody grew silent as Coach began to clean up the smashed pieces, Stiles and Scott calming down from their giddiness. Harper glanced across at Lydia who sat in the desk beside her. She was trying to pay attention to her phone, only she was swatting the air at the same time with a look of annoyance plastered across her pale face.

Harper chuckled, "practising your karate skills?" She joked lamely.

"What do you mean?" Lydia muttered, "there's a fly. It won't leave me alone."

The brunette raised her eyebrows, "there's no fly..."

Lydia's face fell as she stopped trying to get rid of what she thought was a fly. The red head glanced up, her brows furrowed. She was hearing things.

...

"Barrow went after kids with glowing eyes?" Isaac repeated, "he said those exact words?"

The teenagers were panicking as they made their way down the stairs in one of the many hallways of Beacon Hills High, talking about their latest issue. William Barrow was notorious for bombing a school bus a few years ago, killing four teenagers and leaving one with no legs. He was having surgery on himself today at the hospital, only he managed to break free after telling Melissa why he did what he did- he had seen kids whose eyes glowed.

Basically, William Barrow was out to kill the supernatural, and he didn't even really know it.

"Yeah," Stiles replied, walking quickly beside Harper, "and nobody knows how he woke up from anesthesia. Just that when they opened him up, they found a tumour filled with live flies, which in any other kind of circumstance would be all kinds of awesome."

Harper's eyebrows raised as she looked up at him, "I can't believe I love you," she shook her head in disgust, "that is so not awesome, Stiles."

"Think about it-"

"Did you say flies?" Lydia inturrupted them.

Allison, Isaac, Stiles and Harper turned around to face the strawberry blonde that had stopped in her tracks, a slightly horrified look on her face.

"Lydia?" Allison nodded for the girl to explain.

"All day I have been hearing this sound. It's like... this buzzing," the Martin girl explained, a frustrated look upon her face, "remember in Economics?" She looked at Harper, who nodded.

"Like the sound of flies?" Allison asked.

"Exactly like the sound of flies," Lydia confirmed.

...

"Stiles!" Harper wheezed, "some of us have short legs!"

Stiles grabbed hold of Harper's hand tighter, not listening as he pulled her along the hallways in order to find their other best friend. Not only was Harper unathletic, but she was only just over five foot tall, making it almost impossible to keep up with her tall, lacrosse-playing boyfriend.

"Come on," he protested before seeing Scott down the hall and pulling her there, "hey, Scott! Where the hell have you been?"

Lydia ran over from another direction, panting slightly, "the police are leaving. Why are the police leaving?"

"The police?" Scott's eyebrows furrowed, having heard nothing about Barrow or seen literally the entire police department walking down the halls.

"They must have cleared the building and the grounds, which means he's not here," Stiles shook his head.

"Who? What are you guys-"

Lydia cut him off, "he has to be here!" She looked over at Harper, knowing that if anyone was going to believe her it would be the Empath, "that sound... the buzzing I've been hearing? It's getting louder."

Harper bit her lip and looked up at Stiles, "can you talk to your dad?"

Stiles was about to shake his head when he saw the pleading look in her eyes, and he knew he couldn't say no. Stiles had always had a hard time saying no to Harper. Groaning, he rushed down the hall, eager to catch up with his dad who he knew would be leaving any second.

...

Harper waited beside Lydia as Stiles bombarded his father with questions. She could see the dramatic hand movements he was creating and the way his facial expressions changed every second. She knew he was having to do a lot of convincing and she appreciated it.

"Is it still loud?" She glanced over at Lydia.

Lydia nodded her head, "it's not stopping."

The Empath didn't know what to say. She sighed and ran a hand through the hair that she had gone through the effort to curl this morning. Lydia swatted her hand off of it.

"Hey, don't do that," she scolded, "you've actually made an effort with your hair today. Don't go ruining it."

Harper rolled her eyes, "rude."

Lydia shrugged and sighed again as she leaned against the wall. Harper moved from one foot to the other, desperate for Stiles to come back with some good news. For goodness sake, all Harper wanted was some good news.

"Have you told him we made out?" Lydia hummed after a while, her green eyes still on the father and son.

Harper spluttered as they looked over, Lydia sending the Stilinski's an innocent wave while Harper's face reddened. As soon as they turned away from the girls, Harper punched Lydia's arm lightly.

"No, I haven't told him, and I don't think I'm going to, so please don't say anything, Lydia," Harper begged her softly, "we just got back together and with all this supernatural stress going on, we don't need anymore petty drama coming from nothing."

Lydia nodded, "I get it..." She snickered a little, "I would just love to see his face when he finds out I kissed his girlfriend."

Harper rolled her eyes yet again, "you better not."

"I won't," the strawberry blonde shrugged, "unless he annoys me, which he does a lot actually. But if we get into a fight I might bring it up against him, you know? My god, his face when I would say-"

"Guys, we gotta go," Stiles came back over and gently grabbed Harper's wrist, "my dad doesn't believe me, which means-"

"Allison."
