The trickster child

Chapter 3

"Rilie! Give it back!" A young boy with sunshine blonde hair was chasing a young girl with hair cut to just below the ears down the stairs of their home.
"Never!" The girl laughed, charming and elegant for a child. She held a plastic red, blue and white shield in her hand and a plastic army hat on her head.
"Rilie! Give your brother his toys back." Their mother walked out the kitchen, calmly scolding her children. She was beautiful. Hair darker than the night sky braided carefully down her back,  her pale skin had not a signal flaw nor imperfection  and her eyes were a sparkling blue like sapphires.
"Yes mama." The girl handed the shield to her brother and placed the helmet on his head, before smirking and running off- with her brothers BB gun.

"Thor, are you sure this is a good idea?" Steve asked again as they walked back to the room Rilie was resting in.
"He will be a great assistant in helping her with her powers" Thor said confidently, striding in front of the others.
They opened the door to her room, flooding in quietly with their guest coming in last. Rilie ,who was drawing quietly, looked up and acknowledged the new presence of the avengers.
"Rilie, this is...Loki. He will be helping you with your powers." Steve introduced. Loki  ,who was currently dressed in a complete black suit, black tie and black shirt, looked at the young girl sat in bed.
"...how is he going to help me with magic when he doesn't know how to wash his hair?" She retorted, one eyebrow raised and voice confident.
There was a minute of silence before Loki answered.
"You will regret that." Loki growled, insulted at the young girls comment.
"And so will Goldie locks over there if he doesn't stop gossiping with captain patriotism." Rilie retorted once again, not missing a beat.
"...we'll start training tomorrow." Loki announced, trying to hide his growing smirk and the young girl didn't even bother hiding hers. He then turned around and left, quickly followed by his brother.
Just as he was about to leave, Rilie softly called out Steves name.
"...do you think me a monster because of what I can do?" She asked quietly, green energy encasing the tips of her shaking fingers and burning the drawing she was holding in her hand.
"No, what you can do has no affect on if you are a monster- which you're not." Steve reassured, ruffling her short hair slightly. "What you do with your abilities and why you do it decides that. I have no reason to believe you'd do anything without good reasoning." He informed before leaving the room and the girl inside it.
Rilie glanced at the green aura surrounding her shaking hands wearily, almost scared.
~.~.~.~.~.~.~.~.~.~.~
"Morning, sunshine!" Rilie awoke to Brianna's face in front of her face and the smell of food.
"...w'at?" Rilie mumbled quietly, rubbing her eye with her hand then pausing- noticing the delicate raised lines on her face, tracing them across her face. There were two lines across each cheek, three little dot-like ones below each eye that she found before her hand was grabbed by Briannas and pulled away from her face.
"I'll get you a mirror in a bit, now eat!" Brianna ordered, leaving no room for discussion. As Rilie ate the food, Brianna briefly left the room to fetch the assortment of clothes she owned that would come close to fitting the slightly taller girl along with the promised mirror.
"Alright these should fit you, pick what you want. Oh, here's the mirror you wanted and make up- if you want it." Brianna once again left the room to give Rilie some privacy.
"Hmm..." Rilie shuffled through the pile of clothing eventually deciding on a light green long sleeved shirt, leather vest, a maroon cropped blazer jacket, a dark floral skirt and some heels. She went to pick up the mirror but found herself hesitating, her hand shaking and  just hovering above it before grabbing it. The lines she felt on her face were a slightly paler colour shade of her skin, just pale enough to be noticeable.
Brianna was on her phone, messaging her friend from school-Peter Parker.
SpiderBaby: Srsly, ask her.
RecklessIdiot: Dude, I met her yesterday! I can't!
SpiderBaby: C'mon, it sounds like you're head over heels for her.
Brianna looked up from her phone as she heard the door open.
RecklessIdiot: GTG, talk later.
"Hey, you ready to...." Her voice trailed off as she saw Rilie leave the room. 'Damn, Peter was right'
"What? Cat got your tongue?" Rile said in her posh British accent, a black lipstick smirk on her face. Those marks that decorated her skin were covered with makeup and her eyeliner was sharp enough to kill a man.
"Well? Which way?" She gestured with her hand for Brianna to start walking, which she did.
In ten minutes, the two of them were stood in the training room The Avengers had decided was to be used for her training and Loki was already waiting.
~.~.~.~.~.~.~.~.~
"Look Fury, the kid's still unconscious. We don't even know who she is yet. We'll hand her over once Banner says she's well enough for travel." Tony insisted, talking to Nick Fury over a video call.
"You'd better do, Stark." Fury ended the call abruptly, leaving Tony to stare at a blank screen.
"That went better than expected." Steve appeared out of nowhere, commenting on the conversation he'd apparently heard.
"I'm only doing this because your precious little Brianna has a soft spot for her." Tony snarked, heading for the nearest bottle of scotch, pouring it into a shot glass.
"I thought Pepper made you stop that." Steve snatched the bottle out of Tony's hand. "Now, come on, we have to over look Rilies training."
~.~.~.~.~.~.~.~.~.~.~
"THE HELL!" Rilie screamed again as she lost control of her magic once more, an explosion going off around as she lost her temper.
"Calm down, your magic is tied with your emotions. The angrier you get, the more you'll lose control of your magic." Loki ordered, calm and collected. He used his own magic to prevent her outburst from affecting him.
Rilie clenched her fists and let out a deep breath, trying to calm her frustration.
"Don't worry, Rilie! You'll get it." Brianna was sat crossed legged off to the side on a large windowsill, working on a project she'd been given whilst assessing Rilies strengths and weaknesses (and not so subtly admiring her beauty).
"LADY RILIE! HOW ARE YOU!" Thor burst into the room yelling with goofy smile plastered on his face.
"...um, I'm well." Rilie  responded, stuttering ever so slightly.
"Brother, if you dare hug me I will stab you!" Loki snarled as Thor continued to ignore his threat, wrapping his arms around the younger God.
"Hey there, pa." Brianna greeted Steve who walked into the room a lot calmer than Thor with Tony by his side.
"Hello, Bri." Steve pulled Brianna into a one armed hug. Loki and Rilie just stood to the side, clearly confused.
"Oh, right. Rilie, once the paper work gets finished I will officially be 'Brianna Kühn-Rogers', daughter of Steve Rogers!" Brianna announces proudly, practically grinning from ear to ear.
"I see."
"Alright, enough with the smooshy stuff. Reindeer, continue training little miss mass murder." Tony broke up the conversation, forcing him, Thor and Steve to move where Brianna sat.
"Focus your magic, try and make a simple sphere with it." Loki instructed, using one hand to demonstrate.
"Okay."
She closed her eyes, focusing on the power she'd felt when she was running and fighting those people.
"Grab her!" One of them screamed. The man- no. He wasn't human. He was around twenty feet tall, his skin was a deep blue and had the same style markings as Rilie on his skin. There was more of them. Her mother, she was no longer the slightly above average height woman Rilie thought she was. Her neat black hair was now a messy midnight blue, her skin was also that marked blue like those things that surrounded them. Her brother, he was led on the floor, motionless. Rilies hand was blood soaked and resting on her brothers back. It was raining, or was she crying? Or was it both.
"RiLiE? RiLiE!" A girl was calling her but to Rilie it sound like she was underwater and the voice was coming from above the water.
"BrOtHeR, iS sHe AlRiGhT?" A deep male voice this time.
"HaNg On!"  This one was calmer and British.
In the blink of an eye, Rilie was back. Frost covered everything in the room (except the people) and it was snowing gently inside the room. Surrounding Rilie was spears of ice erupting from the area around her feet. Rilie was breathing quickly and shakily, her eyes darting around the room but they were unfocused.
"Rilie! Pay attention!" Loki raised his voice, getting the young girls attention.
"Um, I'll go get some warm blankets." Brianna whispered to her soon-to-be dad, sneaking out of the room after he gave a nod.
"We'll take a break for you to collect yourself." Loki ordered, strict but almost soothing.
"Um, Rilie? I've got some blankets." Brianna had returned to the room with a pile of fluffy blankets. Rilie made no response as a blanket was wrapped around her shoulders and she was carefully guided out of the little circle of ice to the windowsill to sit down. She just stared at her hands. She could still feel the cold blood dripping off of her hands and the bellow freezing temperature.
"Brother, what has happened to her." Thor quietly asked Loki, concerned for the small girl.
"I suspected a combination of amnesia, forgotten Trauma and unstable magic at the same time triggered her to remember something dark and thus lose control." Loki mused, speaking just above a mumble.
Jarvis' voice then appeared, cutting through the near silence.
"Sir, Director Fury has arrived at the Tower."
