IMPORTANT AUTHOR'S NOTE: Okay.. so a handful of chapters for this story was written some time ago and then tossed in the recycle bin. I was and still am self-conscious about this and didn't like the direction it was heading so I gave up. Then the mid-season finale happened and BAMM!, a little inspiration came back so I'm going to give it another shot. This will be the FIRST and ONLY fic that I will be posting that doesn't have each and every chapter completed for it so please be patient and let me know your thoughts about it. If it's so-so decent, I'll gladly pick up the pace and try to knock out more chapters but if it's horrible, I'll kick it back to the bin. I just really want to experiment so if this story gets deleted at one point, don't say I didn't warn you.

So now that that's out of the way, just so you know, I've never written a story that followed through with the way things went down in a certain season but I'm going to try it out here. A certain relationship will NOT happen because as much as they might seem cute together, I planned this fic before I even knew this character was going to have a love interest so yeah.. that relationship won't happen and I'll try to work the season around it. Understand? Also, I possibly might add the cliché scent marking and body warmth of a werewolf.

Enjoy!

Stiles parked his jeep directly on the Lacrosse field, glad that school was finally out. Had Coach Finstock, or any other school official seen his parking spot, he'd had gotten an earful and lecture about not parking his jeep on the field.

"So you really think she's going to come back to you?" Stiles asked, hopping out of the driver's side while Scott climbed out of the passenger side.

His best friend had just gotten done telling him about Allison and their break, and how Allison was leaving for the summer to reflect about the decisions she's recently made. "Yeah, I know she is." Scott answered as Stiles opened up the back of his jeep. "What about you and Lydia?"

"Uh-" Stiles sighed and helped Scott pull out their Lacrosse gear. "-well my ten year plan for making Lydia fall in love with me may have to stretch to fifteen but the plan is definitely still in motion."

The boys took their gear and walked towards the middle of the field. "Why don't you just ask her out?"

Stiles sarcastically laughed. "Yeah, 'kay. Why don't you just get in the goal and help me make team captain like you promised there, big guy."

Stiles set up a good ways away from the goal while Scott stood ready in front of said goal. "Hey, you know what I just realized? I'm right back where I started." Scott voiced.

"What do you mean?"

"I mean no Lacrosse, no popularity, no girlfriend. Nothing."

"Dude, you still got me." Stiles managed to look slightly offended.

Scott grinned. "I had you before."

"Yeah and you still got me." Stiles explained as Scott chuckles. "Okay? So life fulfilled."

"Very."

"Now, remember no wolf powers." Stiles says as he twirls his lacrosse stick in hand and bends down to pick up the ball.

Scott nodded. "Got it."

"Nah, I mean it. No super fast reflexes, no super eyesight, no hearing, none of that crap. Okay?"

"Okay. Come on." Scott whacked each side of the goal with his stick, ready for Stiles to give him his best throw.

Stiles took a second to relax, pulling back to throw only to freeze. "You promise?"

"Would you just take the shot already?" Scott secretly grinned as Stiles readied himself again, his eyes glowing yellow as Stiles launched the ball to make a goal.

Thwap!

"I said no wolf powers!"

The boys spend the rest of the day with Scott "teaching" Stiles some new skills. Of course, that was after Scott stopped using his supernatural abilities and Stiles threatened to stick things in places Scott didn't ever want things stuffed.

The sun soon vanished from the sky and the boys packed up their gear. Scott promised they had all of the summer to practice and even time during the school year since Lacrosse didn't start towards the end of the school year to begin with.

With promises to hang out over the upcoming months, plans of video game marathons and movie marathons with Lacrosse practice in between, the two friends vow to put all the supernatural drama behind them for once and try to move on with their lives.

Stiles soon drops Scott off at his house before making his way home.

When Stiles does get home, it's to find his Dad's police cruiser already sitting in the driveway. Normally, that'd be a welcoming sight but since his Dad was supposed to be working the night shift, it didn't sit well with him. The last time his Dad had come home early, it was because the higher ups didn't think John was capable of serving the County when he couldn't even control his own son.

Throat tightening, Stiles pocketed his keys and made his way inside.

"Dad? You down here?" He called out as soon as the door was shut behind him.

"Dining room.", came John's reply.

Stiles followed the familiar path to the dining room only to find his Dad still in uniform and already nursing a glass of Scotch. Dread pooled in Stiles' stomach as he shakily stepped closer. "Dad?" He gulped when John's expression stayed grim and void of any emotion. "Is everything okay? You didn't get fired, did you?" He asked. He really needed to work on his brain-to-mouth filter.

"No." John grunted and sipped his drink. "Work's fine. We're fine. Don't worry about that." He rambled and now Stiles was really nervous. Rambling was Stiles' tick, not his Dad's. "This is, uh, more personal. It involves the both of us and I don't know-.. I don't want you to-.." John sighed and pinched the bridge of his nose.

"Whoa, hey." Stiles sank into a chair at the table. "Breathe, Dad. Relax." He stated calmly and boy, wasn't this just fucked up. John is usually the one having to calm Stiles down. Not the other way around. "What's going on?"

John took a deep breathe, downed the rest of drink before staring Stiles in the eyes. He didn't need to be a werewolf to know that whatever was going to be said, it was going to be an emotional talk. It was all there in his Dad's eyes. "I, uh, I got a call today at work." John told him. "Took me by surprise, if I'm being honest. She had completely fallen off the face of the earth after the first year and we didn't know if-.."

"Wait, what?" Stiles cut him off. "Who are you talking about?"

Stiles' heart was beating erratically now, his confusion only growing bigger by his Dad's whole demeanor. Who was this she and why did they think she had fallen off the face of the earth?

"We were planning to tell you but then your Mom-" John's voice wobbled and he had to clear his throat before continuing. "-your Mom passed away and I didn't know what else to think and I never got around to telling you because I didn't even know if she was still alive or-"

"Dad." Stiles sighed. "Stop." John shut his mouth. "Breathe." John took a breath. "Now tell me who this person is?"

"Please don't be angry with me." John's voice was meek and vulnerable, and Stiles doesn't like seeing his Dad like this at all.

"Never." He states because who was Stiles to get angry over a secret when he had one of his own. Several of his own that could possibly save numerous lives if he could just tell his Dad that werewolves were real. Magic was real. That the supernatural existed.

Holding his Dad's gaze, Stiles grips one of his Dad's hands that's sitting atop the table, holding it tight and leans forward in his chair, ready to hear what it is his Dad is freaking out over.

"You have a sister." And whoa! Hold the fuck up."A twin sister to be exact."

Stiles is speechless. He's actually speechless with a million questions flashing through his mind but all he can do is sit there, gape, and stare. His grip on his Dad's hand loosens and he slumps back into his seat, heart beating fast, and he just doesn't know what to say to that.

He wants to ask how but he's pretty sure how it happened.

He wants to ask why he's barely finding out but he's also pretty sure his Dad already answered that.

And he wants to know why his sister didn't grow up with them.

The questions are just repeating themselves over and over in his head but he can't work his mouth to actually voice any of them. The second he finally manages to open his mouth, a glass is slid in front of him with the smallest amount of alcohol in it. Stiles picks it up without thinking and downs it, wincing at the burn at the back of throat and coughing when he can't handle it.

Stiles slides the glass back towards his Dad who refills it but keeps it for himself. "Why now?" He finally croaks.

John sighs, picks up his glass and takes a drink. The kitchen falls dead silent but when John finally manages to speak, his gaze is downcast as if he's reminiscing. "W-when your Mom was pregnant, it wasn't exactly planned." He tells Stiles. "And we weren't financially stable to support one child much less two!" John scoffed and took another drink. "We knew we weren't going to be able to do it. I wasn't making enough money and even if your Mom had started to work, we had no money for a babysitter. We had no help at all." His voice wobbled and Stiles immediately leaned forward, gripping his Dad's hand again.

"Dad, it's okay. I'm not mad." Which was the honest truth. He wasn't mad, he was just beyond shocked. He had a sister, an honest god sister. It wasn't just him and his Dad anymore but why was his Dad telling him now?

"We, uh, we didn't know your genders. Your Mom wanted it kept a secret." John explained. "And when she went into labor, she told the Doctor we didn't want to know the sexes because we had to give one of you up and she didn't want to make the decision herself."

"So what did you do?" Stiles asked.

"We asked the nurses to choose for us." John admitted. "When we told them that we had to give one of you up, they were understanding. And then your Mom asked them to bring only one of you back and put up the other for adoption."

"Did you know you the other baby was a girl?"

"Only after all the adoption papers were typed up and she was placed with another family." John said. "None of us could agree on whether we wanted an open or closed adoption so we settled with telling the other family that if they wanted to send updates, we'd gladly accept it. We left it at that but when the family didn't send updates after the first year, your Mother and I grew curious so we attempted to track them down but we couldn't find them."

"And now you finally found something out about her? Are you even sure it's her?" Stiles wondered.

"Oh yeah." John confirmed. "She-.. Avery had her birth certificate with her adoptive parents' names that I attempted to track down. The only reason I didn't find her was because her adoptive parents actually passed away and she was put back into the system and given to a new family."

"Wow." Stiles breathed. "You actually talked to her?"

"I did." John huffed a laugh. "She sounds beautiful. Makes me wonder who she looks like."

The father/son duo fell into a round of silence as John twirled the glass in his hands. Stiles sat there, letting all the information sink in and started to wonder to. If this was all true, who did she look like? Did she have their Mom's eyes or Dad's? Did she resemble Stiles at all because of their twin status? Did she have moles dotting her face and neck like himself?

"So.." Stiles sighed as he rubbed his head, his buzzcut rough against his palm. "-why are you telling me this now? Does she want to visit or something?"

"Or something." John mumbled. When he remained quiet and looked up, he found Stiles staring at him, arms flailing and expecting a better answer. "She's coming tomorrow." John finally blurted. "She, uh, she wants to get to know us so she asked if she could possibly move in with us while she completed her High School career here." Stiles gaped and John hurried with the rest of what he was going to say. "We have that extra room so she can stay in there and she said not to worry about any of her expenses. She says she has that all taken care of."

"Mhm." Stiles hummed suspiciously. "And how does a sixteen year old have all her expenses taken care of already?"

John shrugged. "I don't know, son, but she said she'd explain more tomorrow."

"Oh. Okay then." Stiles' lips twitch downward for a split second. "I guess I'm getting a sister, huh?"

"Looks like it." John nodded.

I guess you can say that I have a thing for OCs. Don't judge me! At least this OC is going to be completely human :) All my other fics have them with some sort of magical ability, vampirism, or hybrid-ism. Lol. But this one is completely human.. so yay! This is a first for me. I hope you decide to stick around.

And in case you haven't noticed the story cover, Avery's faceclaim is Lily Collins.
