Sterek but Evan Buckley is actually Stiles' dad!

A lot had changed for Buck and Eddie in the last three months. It started during a regular night for them, having gone to the zoo with Chris in the morning, they came back home where Buck cooked dinner and Eddie helped with homework. They ate together, watched a movie and Chris fell asleep between them halfway through. Eddie watched as his best friend picked up his son and brought him to bed, following him but staying in the hallway as he watched him tuck Chris into bed with a gentle kiss to his forehead.

He didn't know what came over him, but the second they were back in the living room, he pulled Buck towards him and kissed him. When they had imagined getting together, they always thought it would be in the heat of the moment. Maybe during an argument or as one of them lay in a hospital bed. Though, this was better than either of them imagined. There was no big trauma, no fear, just a normal night where they decided to embrace what was right in front of them.

Three months passed in bliss between them, they rarely argued, they trusted each other, and they got closer than ever before. They had decided to keep it a secret from their team for a while, wanting to stay in their little perfect bubble for as long as possible without the teasing and all the questions from their friends. Buck was no stranger to keeping big secrets, but in these few weeks he had started to feel more and more guilty each day. Not of the secret they kept between them, but of the one only he knew about.

It all came crashing down on him during a slow shift, which he didn't dare to call quiet after what happened last time. He heard Hen talking to someone, walking over as he spotted the clear concern in her tone. As he rounded the corner around the ambulance he gasped, seeing someone he loved more than anything covered in blood and bruises "Stiles?" He didn't get any answer from the young boy as he spotted him. Buck quickly put out his arms as the kid ran to him, jumping into them and burying his face in the older man's neck, holding on as tight as possible.

-----------------------------------------------

one day before

There was a new threat in Beacon Hills, no one was entirely surprised by it. Stiles had been researching the new creature for days without any sleep, needing to make sure his friends and family knew everything so that he could protect them, no matter how they treated him. For months now, the pack had been excluding him, barely talking to him unless it was to demand something and treating him like shit in the rare moments they were all together. The only one who was still by his side was Derek, though he would never admit that they had done anything wrong towards him, always defending his childhood best friend and those who had joined them since that night in the woods.

Everyone would refrain from showing their behavior in front of the old alpha, knowing that he had become protective of their human member in the past few years since he came back. Which meant that the older man had no idea about anything going on, Stiles would never say anything either of course, thinking he deserved everything he got for what he put them through with void. It all came to an explosive end the morning after they had all gone out to defeat the creature that had been terrorizing the citizens of their town. Stiles had gotten seriously injured in the battle that night and woke up to everyone surrounding him in the loft.

He winced as he tried to sit up, noticing that none of them had bothered to check his wounds or clean the blood from his face. He had hoped that maybe they were surrounding him to comfort him, or that they had been worried about him but one look at his former best friend broke that delusion. Scott had been looking at him angrily, with so much hate in his eyes it actually made the human physically flinch back. "What happened last night?" he asked, groaning as he finally managed to sit up without any help from the pack "what happened was that you got in our way Stiles, you insisted on tagging along and the second we got there the creature noticed the weak link out of us and decided to go after you first."

"I had to come with you guys, I would never let you go alone" he replied insistently but that just got him an eye roll and a scoff in reply "please, you really think you could do anything to protect us? The only thing you were good for yesterday was tiring him out, it was much easier to get him after he was done with you. I'm not even surprised he figured out that you were the easiest target, I just can't believe he thought we would stop him." tears built up in his eyes but he refused to let them fall "you didn't even try to get him off me?" he asked, disbelief clear in his tone.

"Why would we? We needed him to exhaust himself so that he would become weaker, the opportunity presented itself and we took it. It's your fault for thinking you would be such a valuable member and deciding to follow us into the woods. We all have powers, and we know how to defend ourselves, you're just a weak human who doesn't know when he's no longer wanted. You were weak when you let void into your head, not fighting him and letting him kill people we actually care about and you're weak now. You clearly don't know how to take a hint so we'll make it easier for you to understand this time. All you do is drag us down, you don't help with anything and you're basically useless to this pack. We don't need you with us anymore, we're done protecting you and having to help you every time you get injured."

He could no longer bear to look at Scott's face as the words left his mouth, deciding to look around the loft instead. His eyes passed every pack members faces, seeing the same level of anger in each one of them as they nodded along to their Alpha's words. There was only one person missing, the only person he knew would never let them speak this way about him "where's Derek?" he asked quietly, not meeting anyone's eyes "he left to see Brayden, he didn't think this was worth his time, he was sick of taking care of you and hearing your whining" Stiles shook his head at that, not believing them "no, he would never say that and he-he wouldn't go back to her. He wouldn't do that to me."

He whispered the last sentence, forgetting that they could all hear him until Scott let out a bitter laugh "aww, you really think he cares about you just because you're sleeping together? You were nothing more to him then a body to use until Brayden came back" his head shot up at the words filled with fake pity, finally making eye contact with someone he used to think of as a brother "how did you-" before he could even finish his question, Scott interrupted him "how did I know you guys were fucking? He told me a while ago; he was laughing at how easy it was to manipulate you and how pathetic you were. He said he was pretty sure you were even falling in love with him, as if he would ever be with someone as weak as you"

He couldn't handle hearing this anymore. Not caring about the pain in every inch of his body, he got up and walked to his jeep, speeding back home and running to his room to pack a bag. He couldn't stay here anymore; he could never face any of them again after today. He packed his clothes, his laptop, and any essentials he could find, not caring about the way he carelessly threw everything in. He wrote a quick note to the sheriff before running out the door and straight to his jeep. He started the car and started driving, only one destination in mind, he needed to see the only person he knew would always love him no matter what.

"Noah. Thank you for taking care of me all these years, but I can't stay here anymore. You've been busy ever since you started dating again and I barely see you anymore, though I don't blame you. I know I was a burden you got stuck with but thank you for raising me the way you did. I don't know if I'll ever be back, but I'll try to talk to you when I can, call me if you need anything. I'll be with the only person I still have in this world; I'm going to stay with my dad."

Stiles drove with tears running down his face, barely seeing the road in front of him but not caring enough to slow down or pull over. He kept driving until he reached LA, finding the 118 firehouse and pulling into the parking lot. He took a deep breath, hesitating to get out of the car. He didn't know if his presence would be welcomed but this was the only place he could think of going. He took one last breath and walked out of the car, through the big doors until he was stopped by a concerned woman walking near the ambulance "hey are you okay? Do you need help?"

He smiled at her kindness but avoided her question, knowing he looked like he had just been run over by a truck, twice. He got straight to the point "is Evan Buckley here?" he asked in a quiet, unsure voice. Before she could give him an answer, they both turned as they heard a quiet gasp "Stiles?" his dad asked, fear and concern in his voice at the sight in front of him. Stiles didn't think twice before running to him, jumping into the comfort of his arms and sobbing. "I'm sorry, I'm so sorry. I know I'm not supposed to come here, and you told me to call before I come to visit but I had nowhere else to go"

He felt the firefighter hug him tight, trying to calm him down but he couldn't stop the words spilling from him "I'm sorry, please don't be mad. I needed to see you; I needed you. Please don't be mad at me" he felt a hand stroke his hair as quiet reassurances were whispered into his ear. He felt his dad slowly put him down, keeping his hand on the back of his neck as he leaned their foreheads together "shh shh, it's okay Sti. I'm not mad, I would never be mad at you for needing me"

He pulled away and cupped Stiles' cheeks in his hands, moving his head sideways to see his face better "I need you to tell me what the hell happened to your face, are you injured anywhere else?" he asked worriedly, not caring about all the confused faces around him. Stiles decided to ignore the first question but still answered the second "I don't really know; I think I took the brunt of it in my face. I might have a couple bruised ribs and I feel a cut on my back, but I don't know how bad it is. I've kinda gotten used to injuries like this, so I'll be fine, but I had to see you."

"We will talk about why the fuck you're apparently always injured later, but for now I need you to let Hen and Chimney take a look at you" fear crosses his features at the idea of being separated from Buck and he grabs his arm instinctively "hey, it's okay, it's alright. You'll still be able to see me the whole time, I promise. They're gonna take good care of you, I trust and love them both like siblings, they won't hurt you" he looks up to catch Hen's gaze, snapping her out of her shock as she walks over silently. She decides that it's not the time to ask any questions and gently ushers Stiles over to the back of the ambulance, Chim rushing behind her.

Buck takes a deep breath, trying to figure out what he should do. He looks up and sees Eddie looking at him, an unreadable expression on his face. He quickly realizes what this must look like to him and rushes over to explain himself, pulling his boyfriend into the locker room for some privacy while still making sure his son can see him through the glass walls.

"I know you have a million questions right now, but I swear it's not what it looked like" Eddie crosses his arms over his chest, not knowing what to think about what he just saw and heard "then please Buck, explain to me why a guy that I've never seen or heard about before just walked in here and jumped into your arms. I can't find a single good excuse for why you looked at someone else like that, why you held someone else like you would crumble to the ground if they let go. From what he said, clearly, he's someone you wanted to keep a secret but there was no mistaking the love between you two. What am I supposed to think right now Buck?"

Buck tried to pull his boyfriend into a hug, but he stepped out of reach before he could "Eddie, I know this looks awful, but I would never in a million years cheat on you" he sighs, closing his eyes for a second to prepare himself, not knowing if Eddie was going to hate him for keeping such a big secret "I-I can't explain everything right now, but I just- I need you not to be mad at me until I can at least give you the full story. Stiles is-" before he can finish, Hen rushes in "Buck I don't know who this guy is to you, but I know you care about him so I think you should see this"

He runs out behind her, not bothering to finish his explanation until later, right now Stiles is his first priority. When they reach the ambulance Chim gives Buck a sympathetic look as he turns back to their patient "kid I need you to turn around and show us your back again" he hesitates for a second, looking worriedly at his dad before doing as he was told, hearing a loud gasp behind him. From his shoulder to the other side of his lower back there were three large scratches, still dripping with blood.

He turns back around after a moment, not able to meet any of their eyes until he feels a hand on his face, moving his head up to look at the man in front of him "what the hell happened to you Stiles" his dad's voice was firm but not mean, clearly trying to conceal his anger at the thought of someone hurting him "you wouldn't believe me if I told you" he replied, knowing he must sound crazy to anyone who didn't live in Beacon Hills.

Buck sighed, deciding not to push further until they got back home "can you guys just please finish wrapping his injuries, he's stubborn and if he doesn't want to tell us what happened then we could be here all day" the comment got a small smile out of him, not thinking twice about his retort "in my defense, I got it from you so it's kind of your fault" the firefighter turned to look at him with a glare, though anyone who knew him long enough could see the amusement behind it "last I checked, being stubborn isn't genetic you little shit"

The rest of the team turned to him, surprised at the sentence. He hadn't noticed what he said until moments later, changing the subject as Stiles took off his shirt and he noticed something "why are there so many bruises on your neck and collarbone?" he asked as he rushed over to inspect them, missing the red that suddenly covered his son's face and neck "um...those aren't bruises" he replied as he ducked his head down, hiding his face from his dad's eyes "Stiles?" he asked slowly, getting his son to look back at him.

"Yeah?" he asked hesitantly "if they're not bruises, then what are they?" he asked, knowing full well the answer but hoping he was wrong "they're uh..." he cleared his throat, rubbing the back of his neck to release some nerves "hickeys" he whispered, knowing that he was heard by the snorts from the paramedics and strangled noise from the firefighter in front of him "Stiles...who THE FUCK gave you those hickeys, I need a name and address. Someone call Athena so I can take her gun, because I swear to God you are too young to be-"

"DAD I'M NINETEEN!" They both winced at the gasps suddenly coming from everywhere around them, in front of them from the paramedic duo to the side, from Eddie and in the loft from Bobby, who was coming down to scold Buck for his language. Stiles was getting tired, and the mention of his hickeys reminded him of who he got them from and the situation he was in "it doesn't matter anyways; you don't have to worry about that anymore. At least not from the same person, or anyone for a while" he continued quietly, picking at something on his jeans as he turned back to the people taking care of him "can you finish stitching me up please, I would really like to go lay down somewhere"

They chose not to ask any questions about the revelation or the sudden change in Stiles' mood. Buck sighed and looked to his team "I'll explain everything later I promise, but can you please take care of him while I talk to Bobby so I can take my son home" if he wasn't already grateful for his friends, he definitely was now "of course Buck, we'll take good care of him" he squeezed his son's shoulder, before walking up to the loft and talking to his captain.

"Bobby, I know I should've told you about all of this but-" he was cut off as his captain put a hand up, signaling him to stop talking "it's alright Buck, you don't need to explain right now. You can go home to be with your son, I'll find someone to cover you and Eddie" his look of relief turned to confusion at the end of his father figure's sentence, which was met with a smirk from the older man "I think you two have a lot to talk about, the rest of the team can wait but you need to have that conversation as fast as possible." he nodded thankfully before rushing back down the stairs and straight to his boyfriend.

"Hey Eds, Cap said we can both leave early today. You know so I can take Stiles home and we can talk" Eddie nodded wordlessly, walking away to the locker room to grab his bag "I guess we'll meet at your house then" Buck called after him with a sigh, rubbing the bridge of his nose between two fingers "I'm sorry Dad, I'm ruining everything for you. I shouldn't have come here in the first place" Stiles got pulled into a comforting hug, resting his head in the crook of his father's neck "I don't ever want to hear you talk like that again, alright? I love you and I'm happy you came to me; I will always take care of you kid"

An hour later, they were all back at the Diaz household, Stiles asleep in the bedroom and the first responders sitting together on the couch in an uncomfortable silence. Neither of them knew how to start until Buck got sick of the silence "will you please say something" he practically begged "I don't know what to say here Evan, you have a son and you never once thought to mention it to me. Not when we were best friends, not when I introduced you to Chris or made you his guardian in my will and not when we started dating. What do you want me to say?"

Buck looked down at his lap, fidgeting with his fingers, nervous about what this could mean for them but knowing he had to come clean "I know this is a lot and I should've told you a long time ago, but it's never been easy to talk about this with anyone. Everyone makes assumptions about me when they hear the fact that I'm thirty-four with a nineteen-year-old... I just didn't want you to think differently of me because I had a kid at fifteen"

"How could you possibly think I would do that?" Buck sighs, closing his eyes and trying not to let his emotions get the best of him as he explained everything "even if you didn't assume, it's never easy to talk about what really happened back then. Stiles' mom died in labor, it hurt me a lot because we were close, even though we decided it would be best not to be together and just coparent him, she was still one of my best friends. I promised her that I would take care of him, but right after we came back from the hospital, my parents sat me down and told me that I couldn't take care of a child when I could barely take care of myself, and they wouldn't help me because it wasn't their job. They called my uncle from California, him and his wife couldn't conceive, they told me I had to give Stiles up or they would leave me out on the streets. I knew that wasn't a life for a newborn, no matter how much it hurt I knew I had to do it. For Stiles. Uncle Noah was amazing though, he promised me he would take good care of him and that I could come see him as often as I wanted. He made sure Stiles knew that I was his dad but that him and my aunt still loved him like he was their own. I will always be grateful to him for giving my son a better life than I could ever have imagined. It killed me every day that I was apart from him, and it still does, it was so hard to talk about him with anyone. I know how the team started to see me after being Buck 1.0, I didn't want to fuel the fire with telling them that I was a teen dad. After a while it just became easier to keep him a secret"

Buck reached over at the end of his explanation, grabbing Eddie's hand "I know it's not an excuse, I should've told you when we started dating or even before that. I know you're probably pissed right now, and you have every right to be, but please don't leave me. I know we can work through this, it-it might not be easy, but I really can't lose you and Chris. You guys and Stiles are the best things in my life, please just give us another ch-" Eddie put his hand on his boyfriend's cheek, smiling when he leaned into the touch "I'm not leaving you Baby. I'm mad that you didn't tell me, but I would never leave you. I'll be here to help you and Stiles for as long as you'll have me"

At this point, both of them had let a few tears escape, hugging each other as tight as possible, needing the comfort in this situation. "We don't have to tell Stiles about us right away either if that's what you want, it seems like he's going through a lot right now and I don't want to add to that. I can just be his dad's best friend for a while if you think that would make him happy" they both looked up from each other at the sound of a throat clearing behind them "sorry to mess up your plan guys" Stiles smiled at them warmly "I'm happy for you dad, and you seem like a really great guy Eddie. I can't wait to get to know you more."

Before either of them could reply, they heard a phone ringing. Stiles took his phone out of his pocket, expecting it to be the sheriff only for his smile to drop at the name that lit up on his screen. He declined the call and put his phone on the counter, trying to hide his emotions at the mere sight of the name "so what are we having for dinner? I thought it would-" more ringing and another declined call "I thought it might be nice if I cooked tonight, it's been a while since I made something for someone else and-" another call, a more forcefully pushed decline button "and I would love to cook with you again-SON OF A BITCH" he yelled at the end of his sentence as he finally picked up the phone and answered.

"What do you want Derek?" he asked angrily, no longer paying attention to the other people in the room "what do you mean, what do I want? I want to make sure you're okay or at least alive!" he replied, voice a mix between confusion and anger "why do you care?" Stiles replied calmly, suppressing all emotions in his tone so that the werewolf wouldn't know he was upset "I care because I went out to get supplies for your injuries and when I came back you were gone, the only explanation I got was Scott telling me that you woke up and stormed off without a word" the younger of the two only heard the first part of the response and let out a dry laugh, void of any humor.

"Oh, you went out for supplies? Well did you find any in Braeden's pants?" he replied angrily "what the hell are you talking about Stiles? I haven't seen Braeden in months and even if she was back, I would never sleep with her! I wouldn't do that to you!" he tried to deny but the young human wasn't having it "there's no point in lying to me anymore Derek, you have Braeden back now and you can finally be with her. You don't need to use me for a quick fuck anymore, I get that it was fun for you to make the pathetic human actually think you could ever be with him but it's over now. I know the truth so stop acting like you fucking care when we both know you don't and never have"

"Stiles I seriously have no idea what you're talking about, none of that is true! Of course, I care about you!" Stiles just rolled his eyes at that "right. Well, if you care so damn much then why did you tell Scott about how easy it was to manipulate someone as weak and pathetic as me? Why did you let that creature in the woods attack me while you stood there and didn't do a fucking thing to help me!?" he heard a car door slam through the phone but didn't pay it any mind "what!? That's not what happened at all! We were ambushed, I was being attacked by three creatures at once and I told Scott to help you and let me deal with the others. I almost got killed but the only thing I could think about was getting you to safety. I carried you all the way to the car and took you to the loft. I didn't want to leave you but I needed to get bandages and herbs from Deaton for your wounds. I was so worried about you and then I came back, and you were gone. I got to your house as fast as I could and all I saw was a letter to the sheriff there. I've been driving like a maniac to LA because I know your dad lives there and I needed to see you in person to make sure you were okay. Why the fuck would I do any of that if I didn't care?"

"How did you know my dad lives in LA?" is the only thing he could think of saying while trying to process all the information he was just given and the inconsistencies "you told me a few months ago, we were lying in bed, and you missed your dad. We talked about him for hours and you told me that I was the only person who knew that the sheriff wasn't actually your dad. I listened to every word you said that night and made sure I didn't forget anything because I know how hard it was for you to trust someone with that" Stiles felt tears start to escape from his eyes, he didn't understand what was going on and he didn't want to believe that Derek was telling the truth only to get hurt again.

"None of this makes any sense! Scott told me what you said! He told me you went to see Braeden! I-I can't do this right now" he hung up the phone before the wolf could get another word out, throwing the device on the table and putting his head in his hands. He forgot about the fact that he wasn't alone during the whole phone call until he felt a hand on his shoulder "Stiles?" he looked up at his dad's confused eyes and realized what that might have sounded like to someone that didn't know about the supernatural "I really want to say that you don't have to explain and that it's alright but I don't know if I can. Why did you refer to yourself as human as if the person you were talking to wasn't one? What did you mean by creature in the woods? What happened to you in Beacon Hills, I need to know the truth"

Stiles sighed, wiping some of the tears from his eyes "you would never believe me if I told you" He replied quietly, before his dad could say anything else they all heard a knock at the door. A tense silence filled the room as none of them moved to get it, Stiles and his dad just staring at each other and Eddie not knowing what to do in the situation. The silence was broken by a voice yelling from behind the door "Stiles please, I know you're in there! Just open the door so we can talk" the young boy froze at the voice "how did you find me?" he replied quietly, no one other than him expected a response as they didn't think it was possible for someone to hear him through the door when his voice barely exceeded a whisper.

"You know I would track your scent halfway across the world if I needed to, I used a hoodie you left in my room" this explanation only served to confuse the two firefighters even more, but Stiles took a deep breath and went to open the door, walking back into the kitchen with Derek behind him. "Why are you here?" he asked, not sure what to make of their phone conversation "I told you I needed to see you face to face to make sure you were okay" he nodded slowly at the explanation "great, well now that you've seen me, you can leave" he replied, turning around and trying to walk out of the room before a hand on his wrist stopped him.

"Can we please talk about this? I swear to you, whatever Scott told you was a lie. I never even told him that we were together, I really was out getting supplies and I would never sleep with anyone else behind your back especially not while you're hurt and almost died in my arms. I would never, never let someone hurt you and just sit back and watch, if you stubbed your toe, I would break the table for hurting you" Stiles was so caught up in the words he didn't feel his pain start to subside, nor did he see the black veins appearing on Derek's arm until he looked down at the end of the explanation and pulled his hand away.

"How many times do I have to tell you not to try to take my pain" he replied, but the older wolf wasn't having any of it as he stepped closer and cupped the younger man's face in his hands "and how many times do I have to tell you to shut up and let me help, taking away your pain can also heal some of the bigger or more visible injuries so stop trying to pull away and just accept that I want to take care of you" he wiped away some of Stiles' tears as he continued "why are you doing all of this?" he asked quietly, still not wanting to get his hopes up, too used to everyone he loves letting him down and not loving him back.

"Because I love you Stiles and I need you to believe that" Derek replied, leaning down to kiss the human's forehead as the last of the bruises and cuts on his face receded "I love you too Sourwolf" as they were about to connect their lips they heard two throats being cleared from behind them, turning around they saw the firefighters with several different emotions playing out on their faces "I guess we should probably explain a couple things"

A/N: y'all already know that I suck at ending most things but I'm gonna leave this one more open than most of the rest because I found the ending kinda funny and it's already pretty long so I don't wanna prolong it even more. You guys can just imagine what comes next!
