"What is so damn important that you needed us here in the middle of the night?" Tony Stark asked as he stormed into the lab.

The helicarrier had taken off two hours earlier so everyone assumed he had flown in using his suit.

"Well we were all here in the middle of the night," Steve growled. "It is now morning, so you don't really have anything to complain about."

"I may have not gotten here until a decent hour, but you chuckleheads still woke Pepper and me up at two a.m."

"And that is precisely when I wanted you here," Fury said blandly, appearing in the doorway.

"Oh hey boss," Stark said rolling his eyes and going to stand by Banner.

He shook the man's hand and nodded to Natasha and Clint.

"So where's Sparky?" Stark asked.

"He was off world when I sent for him. He should be here shortly," Fury answered handing manila folders across to all of them.

"I am here now," came the booming voice of the demigod.

"See I wasn't the last one here," Stark said, throwing a hand toward Thor.

"The only difference between you two is that he came from a different realm," Steve pointed out stiffly.

"I still got here first," Stark said stubbornly, as he folded his arms over his chest.

Steve rolled his eyes as Thor greeted everyone.

"So why did you call us all back?" Clint asked from Natasha's left.

"We have a new threat," Fury answered.

"Don't we always?" Stark asked.

Natasha sighed and leaned into Clint, showing her annoyance at Iron Man, who didn't seem to care.

"There is nothing in these folders," Banner put in quietly.

"Correction, there is almost nothing in these folders," Stark put in pulling the one paper from the file and dangling it in the air for them all to see.

"Frost Giant?" Natasha read from her file.

"Before I tell you anymore, I have to explain the visitors we have on their way," Fury said.

"Great!" Stark said, feigning joy. "Another new person to work with!"

"Actually I'm a rather old person," came a silky voice they all knew too well.

Everyone spun to see the last person any of them expected standing in the doorway. Natasha Romanoff phased easily into Black Widow and threw herself across the room, effectively pinning the god of mischief to the wall by his throat. Her vice grip was beginning to choak Loki to the point of his lips turning blue when a knife blade was pressed against her jugular.

"Let him go, miss Romanoff."

The voice was foreign to Natasha, but the knife blade was not. Many a knife blade had been pressed to the very spot, but it had never been a surprise before. It startled her to hear the rough voice of a female in her ear and feel an experienced hand holding a fistful of her hair, effectively cutting off any means of escape. If Natasha had been thinking about this woman as a friend, she would have realized that they were very much alike.

Faster than lightning, Clint had the point of an arrow pressed against the back of the newcomer's neck just above her armor; right at her spine.

"Move and you die," he threatened.

The girl felt the point of the arrow drawing blood and a low hiss grew from her chest. She threw a glance over her shoulder and could just barely see Clint out of her peripheral vision.

"Put your weapon down," he growled.

She seemed to be thinking; weighing her choices and finally, after an eternity, she let ago of Natasha's hair and released the pressure of the knife. She put both hands in the air and the pressure from the arrow lessened. Natasha still didn't loosen her grip on Loki. Before anyone had a chance to do anything, the girl spun around knocking Clint's bow away from her back and pressing the knife against his neck. She grabbed the hand that was on the bow and locked it under her knife arm.

"Let. Him. Go," she repeated to Natasha.

The moment Clint had raised a weapon to her while she had a knife on Natasha, she knew. She knew he was the easiest target because he loved her and she soon found out Natasha felt the same way when she glanced over her shoulder and saw The Black Widow, her eyes wide, terrified for Clint's life. She had chosen well. She pressed gently on the blade causing Clint's jaw to tighten and eyes narrow. Then something happened she hadn't expected. Something with very large footsteps clambered up behind her and growled. Her concentration broke and she turned to meet the huge green form of the Hulk. Her mouth slid open to form an 'o' shape. She had never seen anything like him. He was huge and menacing, had both hands in fists in front of him and was growling.

"He has a bad temper," Stark said.

She glanced at him. He was leaning easily against the glass, slowly fanning himself with the manila folder, almost enjoying the change in pace. Her eyes shifted back to Clint, who had one hand clamped around her wrist, his eyes trained calmly on her. He could almost be smiling. She looked back behind her at the large, green wall. He grunted and brought his huge eyebrows together. He almost looked sad. Like he really didn't want to kill her, but he would to protect his team. She gulped and let go of the hand that was on the bow, and in turn Clint let go of her wrist. She put the knife on the table and turned to face the room. At that point, Thor blinked in confusion. He had been so surprised to see Loki he hadn't even been looking at her.

"Vynali?" he asked surprised.

She turned her dark eyes on him and a smile spread across her face.

"Hello Thor."

The other Avengers took in her appearance and had no trouble accepting that she knew Thor and possibly came from Asgard. She was wearing worn, brown leather trousers and simple leather boots on her lower half, but she had exquisite Asgardian armor on her top half. The thin leather between the armor and her skin was a maroon color and came down over her chest and torso and fell into an elegant but simple skirt that came to just above her calves. As she moved, they could see it had slits all the way up to her hips to make it easy to move in. The actual metal in the design was also rather simple. The chest plate was sleeveless and went up around the back of her neck. It came down over her chest, leaving ample room for her breasts then down into the abdominal portion. Those were just metal plates overlapping one another for easy mobility, as were the thinner plates around her ribs. There was chain mail all the way down each strip of her skirt, and her boots, they now noticed, had rings of metal around them. Her sword hand was wrapped up to the elbow in the maroon leather, then metal links over that making a rather intercut design. The other hand, in which she held a shield, was plated all the way up over her shoulder making the rest of her arm an extension of the shield itself. She was tall and muscular, but lean muscle, not bulky like Thor. More like Loki in fact. She wore no helmet and her raven hair was pulled back into a pony tail and held there with a strip of leather. Her eyes were round and chocolate colored, and the corners of her mouth turned up, making her look like she was always smiling. Her lips were pink and the bottom one just a bit fuller than the top.

"Vynali what are you doing here?" Thor asked stepping forward.

She glanced at Fury who had put a hand on Natasha's shoulder.

"Please put him down Romanoff," he said stepping into the middle of the room.

Natasha glared at him over her shoulder, but dropped Loki. He caught himself against the wall and stood. He looked no worse for wear, so Vynali turned back to Thor.

"I answered the call of your boss to bring Loki back here to help with your little... pest problem."

"The Frost Giants?" Thor asked.

"Precisely," she said nodding.

She turned and walked back to Loki.

"Wait a second," Stark said holding up a hand.

Everyone knew he had been silent for far too long.

"Is everyone forgetting something? Didn't we just put this guy away for… oh what was it" he pretended to think thought for a moment. "Oh that's right! He tried to take over the world! Not to mention he took over your mind –" he pointed at Barton. "He personally flushed you out of the helicarrier –" he gestured to Thor. "He threatened you with death!" he turned to Natasha. "He broke my house! And he sincerely pissed the rest of us off! Why is he even still here?"

"Because if you want him, you are going to have to go through me," Vynali hissed, standing tall at her full height of six feet.

"Listen princess," Stark began moving forward, his hands outstretched.

He closed the space quickly with his long strides and was right where she wanted him. Faster than the eye could see, she had him on the ground, one arm pinned behind his back.

"Come at me again and you will no longer have an arm, Mr. Stark."

After a second of him writhing with his cheek pressed against the cold floor, she let go and he jumped up. He backed away, eyes wide and disbelieving. She cracked her neck in response. Loki smirked behind her.

"What are you laughing at Rock of Ages?" Stark spat. "Why don't you come out here and stop hiding behind your rather large body guard."

"It's much more entertaining watching her take care of you," Loki said coolly.

"You're not much without that suit of armor, are you little man?" Vynali asked a sly grin touching her lips.

"Why don't I go get that little suit of armor and then we can go a few rounds?" Stark growled advancing on her.

She merely raised an eyebrow at him as he got closer only to have Thor step between them. He stood four inches taller than her so she couldn't even see Stark over his shoulder. Stark had to stop short to avoid running into Thor's rock like chest.

"Why are you helping her?"

"Blood before friends, I'm afraid," Vynali said leaning around Thor, who sighed and looked at Stark.

"I thought he was adopted?" Stark said.

"He is," Thor answered glancing back at Loki. "She, on the other hand, is not."

The reality of the situation hit each Avenger at different times; Stark last.

"Your sister?" Natasha asked when no one said anything for a long moment.

"Yes," Vynali answered stepping around Thor. "No relation to the god of mischief, but Thor and I are siblings."

No one spoke so she continued.

"Daughter of Odin and Frigga. Twin to Thor the High Prince of Asgard."

She paused and glanced at Loki who had his arms crossed over his chest, one eyebrow raised; curious as to the rest of the story.

"That is all of the story I know," she said dropping her eyes then glanced up at her brother. "Did the Allfather tell you the rest?"

Thor sighed again.

"You were taken when we were infants. By King Laufey."

Loki drew back in surprise.

"Then father went in to try and get you back. He could not find you, but he did find you," Thor said looking at Loki. "He took you."

"A life for a life," Loki said quietly.

"Excuse me," Stark interrupted. "Who is King Laughy?"

"Laufey," Thor corrected. "He is king of the Frost Giants."

"Oh," was Stark's answer. "Continue."

"There is nothing else. Vynali grew up in Yodenheim with the Frost Giants; Loki, in Asgard with me."

"Yeah but didn't you look a little different?" Stark asked Vynali.

She nodded.

"As a child I was an outcast. My mother and father told me I was special, but I was not blue."

"That is precisely why they are here," Fury said finally cutting in. "They both know more about our enemies than we could ever learn in the little time we are given."

"But Stark is right," Natasha said. "Loki did try to take over this planet a year ago."

"That is more the reason I am here," Vynali said. "I am Loki's personal guard back home. I make sure he doesn't hurt anyone, and that no one hurts him."

She glared pointedly at Natasha who glared right back.

"But I will help you in any way I can."

"I still don't trust him," Clint said.

"As well you shouldn't," Loki said leveling his eyes with Hawkeye. "I had you under my control for a long time."

Clint uncrossed his arms, ready to string his bow and put an arrow in Loki's head if he kept it up.

"That is enough," Vynali growled quietly at Loki.

He said no more, but Clint's eyes never left him.

"As much as I hate to say it, I think Stark is right. There is no way we can trust him, especially since he is a Frost Giant," Steve said. "And now that we are talking about it, I don't think I trust her either. We don't know whether her alliance lies with Thor or with the enemy. I mean she was raised by them. Didn't she just call the ones that raised her 'mom' and 'dad'?"

"If I was still on their side, why would Odin have appointed me guard to Loki?" she asked turning her cold eyes on Captain America.

"Still," Steve said crossing his arms.

Vynali sighed.

"I know you have a cage built for Mr. Banner, am I wrong?"

Fury nodded.

"We fixed it after Loki ejected Thor a year ago."

"Good. That is where we will stay if it makes you all feel better."

They all seemed to relax instantly.

"On one condition."

They waited.

"No cameras. Even war criminals need their privacy."

Fury agreed and after some interior decorating the class pentagon was ready for use. Vynali and Loki were served an early dinner and escorted to their quarters. All of the Avengers were there, but Thor ushered them away before Loki and Vynali were locked away for the night. The two 'prisoners' watched Thor pace in front of the open door.

"Thor? What's the matter?" Vynali asked her brother.

"I haven't seen you in almost six months," he said finally looking up at her.

Before she had a chance to say anything he was across the room and had her locked in his tight embrace.

"I have missed you sister."

Vynali smiled and returned the gesture, though it seemed strange and forced. She had spent a long time with only the Frost Giants for company before she realized who she really was. It was even longer still before she met Thor and Loki and realized she had family that was like her. That is until she found out Loki was not actually their brother, but a Frost Giant himself. Neither family permitted visiting the other, even knowing what they knew, but Thor always found a way to see her. They had become close. Then, when she had finally come to Asgard, Thor had to be off world for six months straight and she was appointed Loki's personal guard, and they had become much closer.

"You're sure you will be alright in here?" Thor asked worriedly looking at the floor that he knew from personal experience opened up.

"I will be fine. We both will," she assured him.

She knew he really didn't care about Loki, but she included him anyway. Thor touched her cheek gently with his fingertips, his eyes on hers, but his brain much father off in a memory. Finally he smiled and took her face between his palms and pressed his lips to her forehead. She closed her eyes, letting herself breath in the safe aroma that was so Thor.

"Goodnight sister," he said finally pulling away.

"Goodnight," she said stepping inside the cage beside Loki.

Thor pushed the button on the control panel and the glass door slid into place with a hiss. He walked out and as soon as the door closed behind him, the lights went off, leaving everything in an almost unnaturally dark state.

"Damn, I thought he would never leave," Loki purred in Vynali's ear.

She jumped at his proximity, but it was an involuntary reaction. She turned to face him, not that she could see much, but she didn't need to. She had spent so many dark nights in his cell that she knew him better when there were no lights. She traced the sharp jaw line with one finger from his ear to his chin, then up to his lips. They were parted, but only just. She ran her nail lightly along the bottom one and leaned in against him. He chuckled as he ran his hands down her back, expertly unhooking the armor as he went. He was two inches taller than her; perfect for what she was going to do. She looked up and began lightly brushing his neck with her lips. He lifted his chin, allowing her as much access as he could to his flesh. As she passed over his trachea he pulled he armor forward and up over her shoulders. He was used to being quiet with her armor. If they were caught back on Asgard, both of them would be exiled, or something worse. He tossed the armor behind him landing it perfectly on the bed. He pressed further forward, his body hard and lean against hers, no longer allowing her to suck his neck. She knew better than to deny the god of mischief his fun, and she quite enjoyed when he took control. He pushed her hard against the glass, making the whole thing tremble.

"Is this why you didn't want cameras?" Loki asked his voice husky and guttural against her cheek. "You didn't want your brother to see?"

"I couldn't care less when Thor sees," she answered harshly.

"Ahh, well then wouldn't it have been fun to have an audience?"

He purred the last word in her ear making her tremble from head to food. He didn't miss the reaction.

"Yes darling, you would like that wouldn't you?"

Honestly Vynali couldn't think of much else than what his fingers were doing at that very moment. His hands were sliding up and down her stomach, teasingly lightly.

"Loki," she whispered.

He grinned against her collar bone. That was the way he liked to hear his name. Every letter dripping with lust.

"Yes?" he asked nipping the flesh of her breast.

She jerked forward, drawing a bigger smile from Loki.

"You are such a tease," she said letting her head fall back against the glass.

Loki could hear every word, every syllable shaking with anticipation. He kissed the line where her undergarments ended and her skin began, lightly pulling on the fabric with his teeth, sometimes purposely getting a little bit of skin. He continued across her chest then moved lower. He hovered over her hip where the silky fabric hugged her lean figure and looked up. She wasn't looking at him, but he knew she knew what was about to happen. He breathed out slowly drawing a jagged gasp from her lips. Then she looked down at him. Just the sight of him waiting there was enough to send her over the edge, but she held on. For a few more minutes at least. He lightly drew his tongue across her hip bone and down to her inner thigh, making her arch her back and moan his name. suddenly he came back up to her face and pressed a hand against her neck. her eyes shot open in surprise, but she was not fearful. He put his lips to her ear and stuck out his tongue so it just touched her ear lobe. The hand on her neck came up to cup her chin and her turned her face roughly away from him.

"It is not going to be that easy tonight my darling," he murmured. "You brought me back to earth. I am going to make you pay for that."

Oooooh! ahhaha I also just wanted to stress that this is a playful kind of 'I'm going to make you pay for it.' Like a sexual 'you're going to pay.' Nothing bad. they are both going to really enjoy it :)

Anyway, thank you for reading! No please tell me what you think!
