I know I have A Different Fate still up and running and the one shots from A Better Ending will continue even though it's been deleted. But I started watching Teen Wolf again and have fallen in love with Isaac and wish he had someone to help him.

So here goes, it's another OC but hopefully people will enjoy the story.

Please review so that I know I'm doing okay

Two years ago

Gun shots echo around her as she runs for her life, dodging through alleyways and around buildings, they were closing in on her quickly.

The eighteen year old soldier throws her back to the wall as she crouches behind a few bins. She reaches into her pocket, bringing out three small pictures in her hands. One was of her, her little brother and father before she was shipped, another was of her and her surrogate brother and an older one was of her and her best friend before a fire destroyed his life.

"I'm sorry boys. I have to break my promise" she whispered to the two young boys as a tear slid down her face.

The voices and footsteps got closer and she vowed to take out as many as she could.

Two days later – Beacon Hills

A fourteen year old boy runs to answer the door, as soon as it opens he freezes and then breaks down, collapsing onto the floor.

His father runs out to see what's wrong but freezes when he sees the soldiers in the doorway, he rushes over to his son and holds him close.

"She promised she'd be home" the boy sobbed into his father's chest "She promised"

Present day

A taxi pulls up outside of Beacon Hills High, a young woman thanks the driver and slowly walks up the steps with a bag thrown over her shoulder. She smiles sadly as she looks around the school halls and trophy cases, she soon reaches the principal's office and knocks lightly.

She opens the door and smiles softly at the principal behind the desk. He stares at her shocked into silence, he soon finds his composure and smiles at her.

"Hi sir, I was wondering if I can go grab my boys."

"Of course" he stammered as he put a hand on her shoulder. "They are in Chemistry with Mr Harris, it's nice to see you alive Alyssa maybe one day you'll explain?"

Alyssa smiled at the principal and nodded her head, she waves her hand back at him and walks back down the corridors until she stands outside of the room she's looking for. She takes a deep breath and knocks on the door, without waiting for approval she opens the door and stays in the doorway.

Adrian Harris looks away from the board to shout at whoever walked in but freezes when he sees who it is. He looks behind him at the two he knew she was looking for and rolls his eyes at the fact that they haven't seen her yet.

Stiles suddenly realises that Harris had stopped talking, he looks up and goes still in shock at who he sees in the doorway. He jumps up from his chair and bowls into the girl in the doorway, she chuckles as she pulls him closer and then sees Scott, she waves her hand and he joins his best friend in the girls arms.

"Hey Mr Harris, I'm going to steal these two okay, thanks" Alyssa tells him and steers the two boys into the hallway without waiting for an answer

Allison leaned over to Lydia who also seemed shocked by what had happened. "Who was that?"

Lydia shakes her head and looks at Allison who is confused. "That was Alyssa, I'll explain later"

Stiles continued to sob into the girl's chest as she steered them out of the school and towards the edge of the forest on the other side of the car park, soon she was able to slide down against a tree pulling the two boys closer to her side as they continued to cling to her.

"Shh, come on boys I'm okay, I'm here" She soothed as she ran her fingers through both boys hair.

Stiles sniffed and looked up at the girl with watery eyes. "They told us you were dead Lyssa"

Alyssa smiled grimly. "No sweetheart, the men who took me wanted me to seem dead, they didn't expect me to live at all, but I promised my baby brother that I would be back didn't I"

Stiles smiled at her and cuddled into her side. Scott finally calmed down slightly but then he jumped up from her arms and backed away from her.

"Scott?" The two Stilinski's questioned confused.

Scott growled at Alyssa, his nails turning into claws and his teeth sharpening as his eyes turn gold. Alyssa stiffens as she watches Scott carefully, Stiles opens his mouth to say something but Alyssa slowly gets up and soon flashes red eyes at the young wolf in front of her. Stiles freezes as Scott whimpers and changes back to human, she sighs and grabs a hold of him again.

She looks over to her little brother who is watching her surprised.

"Like I said little brother, they didn't expect me to live" she told him softly, watching his reactions.

Stiles grinned at her and jumps up to her side.

"My sister the baddass, beating odds and surviving werewolf life, so do you have a pack? How did you become an alpha? Have you seen dad yet?" Stiles rambled as he pulled her towards his jeep.

"Whoa there kiddo" Alyssa laughed as she climbed into the back of his jeep with Scott and Stiles in front. "Hold your horses okay, I haven't seen dad yet, I came to see you too yet. I haven't found my pup yet though"

Stiles frowned as he looked at Scott who shrugs then nods his head with a sigh.

"Tell you what, we'll go see dad and then we'll take you to your 'pup'" Stiles tells her as he pulls out of the school parking lot.

Alyssa narrows her eyes at the boys, she could smell the nervousness coming from the both of them but rolls her eyes and stays silent for now.

They soon pull up outside the sheriff's department, Stiles looks at his older sister who was bouncing lightly in her seat. She sees him smiling at her and grins back at him as she climbs out of the back of the jeep, Stiles shakes his head and enters the building first, and he is spotted by the desk officer straight away.

She glares at the boy and sighs in frustration.

"What have you done this time Stiles?" she growled "You're dad's in his office"

Stiles puts on an affronted look as he puts his hand to his heart but he can't stop grinning at the look on his dad's face when he sees Alyssa.

"I haven't done anything, I have a surprise for him" Stiles informs the officer who looks at him suspiciously but motions him forward, not noticing the other two.

Stiles knocks on his dad's office door and opens it, his dad is behind his desk looking at some files, he glances up and glares at his son with a sigh.

"You're supposed to be in school right now Stiles" His father informs him sternly

He raises his hands in surrender and steps out of the way to reveal Alyssa who smiles softly at her dad as tears begin to form in her eyes.

"My fault, I pulled him and Scott out" She told him softly.

Her father slowly gets up from his desk and walks towards his daughter slowly, as soon as he could, he reaches out and puts his hand lightly on her shoulder.

She takes a hold of his hand and places it on her cheek as tears run down her face. "I'm home daddy"

The sheriff lets out a sob and pulls his daughter into his arms, burying his face in her hair as tears flow freely, he soon pulls Stiles and Scott into the hug too.

After five minutes of standing there, the sheriff takes a hesitant step back, clearing away whatever tears were left from his face with his sleeve. He looks his daughter up and down and frowns at the weight that she seemed to have lost as well as the scars that he could see by her neckline. He places a hand near one of her scars and looks at her confused and worried.

"I'm okay daddy, they won't hurt me ever again" she told him softly

Her dad nods but then looks over at the stacks of paperwork on his desk, his eyes flitted back and forth and he gave a groan that was only audible to Scott and Alyssa.

"I need to settle back home dad, why don't we order Chinese tonight and watch films all night maybe you could take tomorrow off?"

Smiling, he nods and gives his daughter a kiss, not wanting to let her go anytime soon, but she soon starts to squirm in his grip. He smiles at her as she grins, she gives him a peck on the cheek then leaves him to his paperwork, and he looks at the dreaded files but has a higher determination to finish the stacks quicker.

As soon as the trio climb into the jeep, Alyssa orders her brother to take her to her pup.

"Look Alyssa, things have happened and well..." Stiles starts but is cut off Scott.

"It's Allison, Boyd hasn't turned up to school" Scott tells Stiles who groans, "Let's go check the rink."

The trio arrived at the rink quickly, Alyssa was confused as to what was going on so after checking the surrounding area she soon picks up on three unknown scents entering the building, she follows them and soon finds her brother unconscious against a wall, she hears his heart beating fine so she continues after his attackers.

She comes out into the rink only to find Scott being attacked by two other wolves while two others watch.

Alyssa growls and shifts, she jumps over the rails and lands on the ice, slipping slightly but she grabs the female and throws her across the ice away from her brother's best friend. The others stop and watch her, a snarl comes from in front of them.

Alyssa looks up and growls furiously as she sees the red eyes of another Alpha but she soon stops and stands straight as she looks more closely at the Alpha, she looks around again and spots the other werewolf who was watching her closely, she whimpers and slowly reverts to her human form shocking the both of them.

Isaac is soon in her arms sobbing into her chest like Stiles did when he saw her that morning. She whimpered again as she felt the pain and despair that radiated off of the young boy and then looked up at the Alpha in front of her.

Derek stood frozen to his spot, he watched as his youngest Beta clung to her. He wanted to run to her and pull her into his arms promising that he wouldn't let her be hurt again but she was an Alpha too, she was a threat.

"Derek?" she asks lightly breaking him out of his thoughts

"How?" he replied stiffly.

Alyssa grimaces "They took me and after about a year of their fun decided they were going to change me, either watch me die or have a pet they couldn't kill so easily. And well, after they bit me I killed them, all except one because he got the best of me and sold me to a stronger pack who actually allowed me to kill him"
