Infidelity & Scandals

Chapter 4: The long waited arrival & explanations

Stiles woke up with a gasp and immediately sat up straight. What the hell? What time is it? The teenager thought while glancing at his clock.

7:oo

Stiles groaned into his pillow and cursed those pills Deaton gave him. This recent nightmare he had was…intense. Stiles pulled the sheet off of him and noticed it was slightly damp which was most likely due to the fact that the hot flashes he had because he tended to sweat a lot during them. Stiles sat up and rested his back against the cool headboard and pulled off his shirt. He normally wasn't the type to sleep to lounge around the house shirtless but he was hot and he could really care less at the moment. Besides he didn't have a terrible body it just wasn't as great as those around him ahem…Scott and his Der-his previous acquaintance.

Aw fuck.

He promised himself he wouldn't think about him anymore. He shouldn't still care; he cheated on him and didn't even try to explain. Stiles clenched his jaw tightly and grinded his teeth. What did he do wrong? He tried to be supportive, caring, less annoying, and he even got into some arguments with his best friend because he defended him and how does he get repaid? Derek (who by the way is the biggest douche in the world) cheats on him. Sigh, maybe Stiles saw this coming this whole time. Who wants to deal with a hyper active human kid, he was so breakable and fragile and more than anything he was useless.

Stiles felt a tear slide down his cheek. Oh God when did he turn into such a girl.

Fuck him and Ms. Bla- No Stiles won't bash her. It wasn't her fault that she was completely clueless and naïve. Jennifer didn't know the connection that Stiles once shared with Derek and she didn't even know that the two had any involvement. She didn't know that the reason he wasn't paying attention in her class was the same reason she had the faraway look in her eyes and a smile that made Stiles stomach turn. Every time he saw her it was painful because all he heard was her moaning Derek's name, his Derek, every time she smiles and tells Stiles, "what's wrong?" his heart breaks a little more. Some days he just looks the other way and other days the pack glares at her and tells her off. None of them look at her the same but of course that is expected when she is the woman that their "dad" cheated on their "mom" with.

Some days the teenager feels like he's in some drama TV show, man he really is in a soap opera.

Stiles sighed and ran a hand over his face he really did need to take Lydia's advice and forget about it and let her and Erica do the damage. Stiles smiled at the thought of Erica, he really did miss his superwoman. She would know exactly what to say right now because in some weird way she understands him.

Stiles eyes snapped closed before he had a flashback from his dream. Erica was in it and her image in his head must have triggered the nightmare.

*Nightmare*

"Erica, do you mind if I talk to Stiles alone? You know with you gone and arms not wrapped around him." Came a growl that was both familiar and foreign to Stiles. Erica grinned wickedly at the man before tightening her grip on Stiles. "Mmm see that might be a problem I don't quite like to share my Stil-."

"Erica seriously get the hell out or I'll make you! I need to talk to him alone!" The man's eyes flashed a brilliant electric blue and he bared his teeth. "Ooh feisty I like that in a man but I will go. Not because you told me to but because I am needed somewhere else…"She said with a frown.

Stiles looked at Erica and nodded in understanding. Yes, he wasn't a werewolf but he heard the howl of the alpha too. She was needed and whether she wanted to leave or not she had to go. "Exactly so go on ahead and be a good little beta and help your mighty alpha." He spit it out barely containing his anger. Erica growled and allowed her eyes to flash before sprinting off in the other direction of the woods. "Jeez D what was that about?" Stiles asked with an amused look. "I don't like her or any of the members of the Hale pack for that matter." He said with a grunt. Stiles walked up to the werewolf and wrapped his arms around him. "Aww you know there all not that bad, Erica is pretty cool." The human said planting a soft and lingering kiss on the other boys' cheek.

"D" growled possessively and gripped Stiles' hips and whispered in his ear, "You're not just going to leave me with that are you?"

Just as Stiles was going to reply he heard a familiar roar. He immediately stiffened because he knew that growl anywhere and the small hairs on his neck stood up. Stiles took a shuddering breath.

Aw shit. No it couldn't be him why would he show up?

"Let him go or I'll just reconsider that thing about letting you stay in this region." The alpha growled in his full form. The omega werewolf transformed as well and pushed his Stiles behind him. "Listen I've told you before you're not driving me away no matter how many times you threaten me!" D growled dangerously low. Normally Stiles would have found it hot but at the current situation all his brain was processing was warning bells. The alpha turned to Stiles his red eyes met his before commanding him, "Stiles get away from him or I am going to have to teach you another lesson. Then again you might like that."

The alpha snarled and his upper lip curled showing his canines and his bright red gums. "D-Derek you need to stop. Please just leave me-us- alone." Stiles begged trying to walk around the omega to get a better look in his eyes. He needed to resolve this confusion between them. Derek growled even louder and pushed the omega aside and in a flash he pinned the teenager to the ground. "No! There is no 'us' as you and him, he is nothing but pitiful and disgraceful omega. Why would you want that? You have me. You're mine and only mine." He said as he nuzzled into the teenagers neck. The omega got up and laughed wickedly at the alpha.

"Hahaha, that's a good one Derek. Well I don't know if you haven't noticed this Derek but Stiles hasn't been yours for a while. You know ever since you cheated on him with that woman. "D taunted as he launched himself on the alpha's back. Derek roared and flipped his onto his back in attempt to make the omega fall off but his grip was tight and his claws were firmly implanted on his sides.

"D-Derek! Oh no what the hell happened? I just left for five minutes! He sniffed me and then went all alpha mode and just ran straight over here!" Erica said while panting and placing her hands on her knees. Stiles couldn't even process what Erica said because his whole focus was on the werewolves. Currently Derek had flung the omega against the tree and growled. "Don't you ever do that. Ever. Now for touching what is rightfully mine I'm going to rip your throat out with my teeth." He growled while pouncing forward in attempt to grab the omega.

"STOP!" was all Stiles said rushing to D's aid.

And that was it, he woke up from there. Who was D and why was Stiles acting like that towards him? He still hasn't managed to get a good look on his face after all the nightmares. Why was Derek so pissed and claiming he was his? Stiles was not property and he'll be damned if he'll be referred to as such by Derek fucking Hale. Stiles would admit that when they were together he loved it when Derek referred to him as such 'cause it was hot in his possessive little ways but now Stiles just found it plain annoying. Stiles sighed and grabbed his towel before heading into the bathroom because he really did need a shower. Stiles let the water run and stripped down until he was naked. Stiles was just about to hop in the shower before catching a glimpse of something on his back. "What the h-." Stiles cut himself when he turned around and saw what was on his back. It was a triskele on the same exact as spot as guess whos?

Derek fucking Hale! Now how the hell did that get there! Oh he was so calling Scott for this one.

Ring. Ring.

"Please tell me you're here!" Cora said when she answered the phone followed by a groan. Decyln chuckled, "I'm glad you're so anxious about my arrival." Cora laughed before replying, "You have no idea. Where the hell are you anyway? It's been three days!"

"Well at the moment I'm at Stiles' you know just checking out the layout to get accustomed." He said while circling around the perimeter of the house. "What? How did you-." Decyln cut Cora off in mid-interrogation and said, "Don't worry sweetie I have my ways and people that I call." "Well he isn't home at the moment so you can't stalk him properly." Cora said dryly. "I am well aware of that Cora, so when can I meet Der-."

"What are you doing here omega?" Decyln flinched at the title before turning around all the while dropping his phone and crushing it with his foot. "What's it to you?" The boy sneered. The older man looked at him up and down as if he heard wrong. "I'm the alpha of this region," He paused and flashed his red eyes to show authority before continuing, "that's what now state your business here or I'll have to show you the price of stepping into Alpha's private property."

Decyln raised an eyebrow at the alpha. "Oh yeah and how would you do that?" He asked with a smirk. Derek remained completely impassive while looking at the boy again. "Tell me what you're doing here or I will rip your throat out with my teeth." The alpha said with a wicked smile before flashing his eyes again. Decyln laughed and rolled his eyes before replying, "Oh that's very original. By the way the whole I'm an alpha crap bow down to me crap doesn't work on me and I'm not scared of you so save the threats."

Derek grabbed the omega by the throat and pinned him to a tree and growled. "Listen kid you better be lucky that most of my pack is made up of a whole bunch of mouthy brats so consider yourself lucky I'm used to teenagers and their need to act tough and high mighty. That is the only reason you are no dead and it's keeping me from slashing you ear to-."

"Oh what happened to the whole ripping your throat out with my teeth that sounded pretty cool-"

Derek gripped his throat tighter and shoved him into the tree more roughly. "Oof yes I like it rough." Decyln said sarcastically. Derek allowed his nails to come out and pressed his thumb and pointer finger in Decyln's neck drawing out two thin lines of blood from the holes. "As I was saying you may not remember how to act in the presence of an alpha since based off your scent you haven't been around one in a while. So let me enlighten you with some information since you have clearly forgotten, omegas or you are the lowest scum of all scum in the messed up monarchy us werewolves have. Yes it unfair to lowlifes like you but you guys deserve it…in most cases. Then there are alpha's also me who are on top so you treat them with the utter most respect, got it?" He said roughly. "There's a reason I don't follow alphas," Decyln looked Derek in the eyes and continued, "It's because there all controlling sick fucks like you."

Derek growled and gripped the boy tighter as he tried to squirm his way out of his grip. "Listen omega I'm warning you that omegas don't last long alone, they're weak and always end up dead. There are hunters that don't treat omegas too nicely and will in fact slice you in two pieces." Derek said as he threw the boy on the ground roughly. "Listen thanks for the concern and warning but I've been on my own for quite a while, six years to be exact. Truth is I don't need a pack to be stronger I'm strong enough on my own; a pack just holds me back. As for hunters I know how to handle them no need to be worried, I've been dodging them for six years now Beacon Hills won't be any different." Decyln said as he got onto his feet and swayed ever so slightly. "Yeah sure you are but it's not only me you have to worry about there are others who will kill you without the slightest hesitation. As a matter of fact you probably came to Beacon Hills at the worst possible time due to the fact there's a war going on and the whole pack of alphas won't appreciate your actions." Derek warned with a snarl. At this Decyln froze and his whole demeanor changed, "Alpha pack you say?" He asked with a slight smirk. "Yes and don't even let me mention the Argent hunters who are supposedly retired. They really aren't and there's other hunters who have no code so just watch your step. I'm the nicest person you'll meet here so I recommend to not get on my bad side." With that Derek backed away from the omega shooting him a warning glance.

"Right sure you because you just give off that I'm-a-nice-guy vibe," Decyln said sarcastically and then paused to nod his in the direction of Stiles' house, "anyway how come that guy's house is your private property? Based on the scent from inside the house-."

Derek growled lowly in his throat and once again grabbed the omega and pinned him by his throat. "First don't ever go in his house no matter how dumb he is to leave his windows open. Stay out of his house and off of the property and more importantly stay away from him, got it? This is you're one and only warning." Derek spit out and tightens his grip in emphasis. Decyln pushed Derek off of him using his strength. "Listen I'll take your advice and stay out of the alpha shit that's going on and I'll do my best to stay out your way but from him I don't know," Decyln pauses and smirks at Derek's low growl, "you know because I have to go to high school and stuff and we might have some involvement you know same age and all." Derek just glares at him and sprints out of the forest.

"Whoa someone is certainly a drama-alpha aren't they?" Decyln chuckled and walked to the meeting place he agreed with Cora. Beacon Hills was way too much of a small town for him but it was comfortable, he could stay here for a bit.

"Stiles, can you please tell me why you called me at eight a.m. on a Saturday morning?" Scott asked grumpily as he plopped on his bed with a groan. Stiles rolled his eyes at his best friend's antics. "First before I tell you a recent discovery I made I want to ask has there been any updates with Deaton?" Stiles asked as he sat on his rolling chair. At this Scott sat up on Stiles' headboard with a frown. "Yes actually he did, he's glad that you stopped puking your guts out but now he's worried about your cold and hot flashes. I told him that your body gets up to about 107 degrees and that's defiantly not normal. He said that typically it can be a sign for a serious infection but your case its obviously more delicate. He told me to keep you hydrated but he told me to try healing you when you get that high especially when it climbs because it can be deadly. He of course freaked me out and I started hounding him down even more questions," Scott sighed and ran a hand over his face, "I told him about your nightmares and he has a lead. He told me that…it has something to with your bond with…with Derek. He said a long time ago that the Hale family was a small pack when they first started off which was like centuries ago. Turns out the Hale pack goes way back so when they mated it was serious business and there was rituals. They wanted to be a pureblood pack which of course means that it's strictly werewolves. No humans are involved at all. So that means that even if you're mate was a human it was not allowed due to the fact that it was forbidden and they wanted to keep the pact pure. See half-bloods or a person who has a parent that's human and another that's werewolf, are physically weaker than a pureblood which was why the Hale's wanted to be strictly pureblood. They wanted power and respect from other big packs and coming from purebloods is a great way to go."

"So," Stiles paused looking for the right words, "how does this tie in with me? I mean I like the history lesson and all but I'm really curious how this has to with me."

"Right," Scott blushed slightly and rubbed the back of his neck and continued, "so of course the whole pure blood thing didn't last forever and eventually a lot of the members started rebelling. So after a lot of blood shed the heads of the Hale pack relented and allowed certain cases to interbreed with humans. See if you were in the Hale pack you couldn't just date a human and sleep with her or him you had to be positive that they were your mate if you didn't want to be punished so you had to be given a blessing by the Hale heads. So this is where it gets creepy, one of the rituals of the mating test to be allowed is this body connection."

Stiles raised an eyebrow at this. "Body connection? Doesn't sound like anything really."

"Well it is important, really important it might be what you and Derek are doing. See the thing about body connection with a human is that the Hale heads didn't want the werewolf from there pack to know what they were doing." Scott said.

"So you're telling me that the Hale heads would perform this body connection thing on the human mate without the werewolf knowing in fear they would rebel? How did they manage that?" Stiles asked.

Just as Scott was about to reply the doorbell rang. Scott sniffed the air slightly before asking, "You ordered pizza Stiles?"

"Yeah man I'm starving! Come on we can talk while we eat!" He said as he rushed down stairs. Scott rolled his eyes but followed the teenager downstairs.

"There you go man thanks for the tip!" The pizza guy said with a smile and a wave as he left.

"No problem dude." Stiles said as he closed the door and brought the pizza, curly fries, soda, and hot wings upstairs. "Scott buddy help me with this please while I get the plates and stuff." Stiles said as he was balancing all of the items in his arms. "Sure thing." Scott said with a chuckle as he grabbed the stuff out of his hands. "Greta I'll be right up!" Stiles said as ran downstairs.

Scott sighed as set all of the food down on Stiles' desk. He opened the box and his eyes immediately brightened. Man these were the moments he really loved Stiles meat lovers pizza was no doubt the best and with mushrooms and green pepper. "Alright Scott I'm back! Let's eat." Stiles said as he handed him a plate, cup, and napkin.

Stiles took a huge bite of the pizza and as did Scott they both burped at the same time after their first slice and grabbed for another. For some reason Scott in that moment smiled, he felt normal and he hadn't felt like that in a while. It was nice to eat pizza with Stiles and just burp. Just like old times when they were fifteen and were just worrying about passing the chemistry exam they had on Monday. Stiles gave him a big goofy grin back and Scott knew he felt the same.

"So…" Scott cleared his throat and took a sip of his soda before continuing, "as I was saying they would perform this ritual by injecting them with something at birth so anytime they had sex or bonded with a human said human would have side effects and depending what they were it would determine if they were the true mate or not but it was only with pure bloods and humans, so if you were a half blood and bonded with a human you were in the clear."

Stiles nodded taking in the information carefully. "So you're telling me that there is a possibility that I might be suffering this crap because of Derek and his fucked up background?" Stiles asked. Scott nodded in response. "Deaton is not sure quite yet because he is still looking up the side effects to see if they match and to see what they mean." Scott replied. "Ok so we have a lead which is good! We're finally getting somewhere! Thanks a lot man it means a lot that you're helping me with this." Stiles said sending him a smile. "No problem I'm glad I can help anyway I can." He said with a grin. "Want a beer?" Stiles asked as he flopped on his bed and reached into his mini fridge. Scott smiled knowing it wouldn't affect him, "Sure."

"So man how are things going with Allison?" Stiles asked with a laugh. Scott groaned and flopped onto his bed too. "Oh man did I tell you what happened in the closet?" Scott said as he covered his face with his hands to hide his embarrassment.

Stiles chuckles before shaking his head. It's nice being normal even if it's just for a bit, Stiles thought.

"Oh no! Stiles you are not still moping in your room like you just got out a bad breakup yesterday!" Lydia snapped as she entered Stiles room with Allison and Cora. "Stiles you can't still possibly be upset at my idiotic brother." Cora said with an eye roll.

Lydia sighed before pulling the cover off Stiles and Scott. "Scott you're not any help either! Come on you are supposed to be making him feel better not making him feel worse! Allison go find me some garbage bags please!"

"She does have a point Scott and why are you guys all snuggled up in the covers? Pizza boxes and is this-oh yes this is beer!" Cora laughed while picking up the beer with her finger. Lydia gasped and shot Scott an annoyed look. "Beer come on who the hell drinks beer?" The strawberry blonde said with an eye roll.

"Can you at least let me wake up properly? Dammit, where the hell is my shirt? Ugh these hot flashes are annoying the hell out of me!" Stiles said as he pushed the remaining covers off of him. "Uhh I think you left it in the bathroom man." Scott said while rubbing his eyes cutely. "Bathroom, of course! Why didn't I think of that before again?" Sties said while heading to head to the bathroom. All the girls, including Allison, who is now, back with a trash bag, stared at Stiles. None of them ever saw him shirtless. Lydia put her hand up to Stiles' chest to make him stop before talking, "Why have you been hiding your attractive body from all of us? I mean come on it actually does look nice…really nice if I don't say so myself."

Stiles blushed at Lydia's comment and cleared his throat. "Well uh…I mean it's not all that I mean Scott has-." "Oh shut up we are not talking about Scott's body we're talking about yours." Lydia cut off and licked her lips involuntarily. "Lydia you're practically eye fucking him, please stop acting like you never seen a male body on your life. I mean if you really think about it only makes sense he is on the lacrosse team so his body has to have some muscle." Cora said with an eye roll.

Allison blushed before adding her own opinion, "Yeah it does make sense but I just never…actually I never even imagined Stiles' body at all because well he's Stiles but he has a nice body-."

"Aww thank you Allison but it is not all of that-." "Dude if you reference to my body again I swear just take the damn compliments they're giving you!" Scott cut off in exasperation. "Yes Scott is completely right and I have made up my mind on what we're doing tonight, all of us because we're young and single! It's Saturday and that means we shouldn't waste it on doing nothing!" Lydia said with a wicked mischievous gleam in her eyes. Everyone looked at her suspiciously except for Scott who seemed to be pretty pumped about it. "Everyone has fake id's right?" Lydia asked while pulling out her phone and typing away. Of course everyone in the room replied with "yeah" or "yes". Cora looked at everyone uncomfortably before mumbling a "no". Lydia stopped her typing before her head snapped up and looked Cora dead in the eyes. "You're seventeen and you don't have a fake id?" The strawberry said in disbelief. Cora rolled her eyes before replying, "Well excuse me that I don't it hasn't been my main priority."

"Right," Lydia looked back down at her phone and finished typing whatever she was and pocketed her phone before continuing and looking at everyone, "well I know you all are practically dying to know what I have in store for us tonight. Well we are going to a club that is hot just a little outside of Beacon Hills. It is only about five-ish so we still have loads of time but we have to go shopping so we all look like twenty-one years olds that actually know what they are doing. Oh and we need to get Cora a fake id but Danny can do that with no sweat, he's coming with us."

"Well I don't know about you guys but I'm actually a little excited." Scott said breaking the silence. A smile broke out on Allison's face. "Yeah I think it will be fun experience." The brunette said. "Umm guys I'll be right back I have to make a call but yeah I will come." Cora said stepping out the room smirking.

Ring. Ring.

"Yeah, what's up Cora?" Decyln said with a grin as he plopped on the hotel's couch. "Hey I'm good but I actually wanted to invite you somewhere with my friends." She said while her smirk widened. "Oh? Well it sounds interesting enough…where to?" He asked. "To a club and before you say how much you hate clubs and all of that 'cause I know that you do I just want to say that I really do want you to be there and besides Stiles will be there I know you've been wanting to meet him." Cora said while biting her lip. "Well I do want to meet him but I don't know. A club I mean can you guys be any more cliché?" Decyln laughed before running a hand over his face. "Well Lydia she is arranging this whole thing and she's getting me a fake id and I'm pretty sure if I tell her you're coming that she could get you one." Cora replied.

"Ugh, you know what fuck it. I haven't been in a club in a while so what the hell, right? Sure count me in." The werewolf said while getting up from the couch. "Really? Wooh I thought I was going to have to beg you but this is perfect! I will let Lydia know and I'll text you the details later." Cora said and a small beep following after.

Decyln chuckled to himself and headed to the bathroom. If he was going to meet her whole pack then he might as well look good.
