AN: So this is my first Avengers fanfic so please no bashing! This is my take on what happens to Loki when he and Thor return to Asgard. There will eventually be Loki/OC. My OC is Waverly and I made her be Clint's sister for an added twist, so please don't complain about that! The story shifts from Loki's POV to Waverly's POV. I haven't read the comics so this is based solely on the movies "Thor" and "The Aveners." I'm not totally sure where I'm going with this so I'll welcome any suggestions. Please read and review. I hope you like!

Disclaimer: I own nothing except my OC!

Chapter One:

"Loki can return to face Asgardian justice on one condition," Director Fury said, his voice determined. "Otherwise, SHIELD will determine his fate."

"And what is the nature of this condition, Director?" Thor asked.

"One of our agents will accompany you back to your home realm. Then, they will act as our contact between the realms. I want to keep tabs on the bastard for obvious reasons."

"You do not trust that I am capable of dealing with my brother's crimes?" Thor thundered. He rose from his chair.

Agent Romanoff stood as well, in Fury's defense. "That is not what Director Fury is suggesting at all," she said in her level voice. "We simply want one of our own present, who's full attention can be given to Loki. You, Thor, as king of Asgard, will have other duties. We can't trust to be in contact with you at all times. If one of our agents is there, we will feel much more at ease."

Thor dropped back down into his seat. He was quiet for a moment, his eyes thoughtful. Finally, he nodded his head. "Very well. Who shall be accompanying my brother and I to Asgard? Surely not another Avenger."

"No," Fury said. "A volunteer actually." Fury stood from his chair and left the room. Thor looked at Natasha expectantly but she did not give away anything. When Fury returned, a small girl followed behind him. Thor had to admit he was shocked. His eyes widened as he surveyed the girl. He was expecting Agent Hill or someone… larger.

"Thor, this is Agent Barton," Fury said. The girl held her hand out to Thor.

"Pleased to finally make your acquaintance, Thor," stated Agent Barton.

"Barton?" Thor questioned. Still, he held out his hand and gingerly shook the girl's, afraid of breaking it.

"Yes. Waverly Barton. Hawkeye is my brother."

Thor had to smile. Knowing this girl was Clint's sister made him feel much more comfortable with the situation. If this girl was Clint's sister, she must be more deadly than seemed at first look.

The god of mischief sat hunched over at the table in his cell. He wasn't quite sure how he landed in this situation. He had the tesseract, he had his army; he should have won. Earth and her pathetic humans should be clenched in his fist, bowing to his command. But, instead, Loki was a prisoner in the palace of his home realm. It was all thanks to the Avengers and his brother. Oh, how Loki despised them. His hands balled up into fists and he felt the anger churning in the pit of his stomach. Leave it to Thor to ruin his plans, just like when he tried to destroy Jutenheim. And then Thor's new best friends had to get involved. Loki subconsciously rubbed the back of his neck. He was still sore from when the Hulk threw him around like a blasted rag doll. Loki felt his cheeks begin to burn at the memory of this embarrassing incident.

Loki pushed himself from his chair and began to pace his cell. He had been locked up for less than a day and was already restless. And unlike his stay on the helicarrier, there was no one here to manipulate; no one to play with.

Loki stopped pacing at the sound of a knock on the steel door of his cell. He looked through the small barred window to see the top of someone's head. Seconds later, the sound of a key fumbling in a lock could be heard and the door swung open.

Loki couldn't help but raise his eyebrows. They had sent a child to his cell? Loki looked the girl up and down. She was short, not even reaching his shoulders. She had a thick head of brunette hair that swept around her shoulders in a soft curtain. Her eyes were big and brown, taking in the sight of the imprisoned god. She was dressed in the same type of clothes that Asgardian servants typically wear. In her hands was a tray of food.

Loki blinked at the girl and she slowly stepped into the room. Over her shoulders, Loki could see the profiles of two large guards who put his brother's girth to shame. The girl was walking towards Loki's table, but he could feel her wide eyes on him. Her face was pale and she looked rather uneasy. No one to play with? Looked like that changed.

The girl set the food on his table and turned to leave the room.

"Thank you, kind miss," Loki said in his eerie, but charming, voice. The girl stopped and turned her face back to the god. She looked thoroughly shocked.

"Welcome," she mumbled.

Loki stepped towards her, closing the gap between the two. That's when he sensed it. This girl was not of Asgard. His lips curled in a snarl. "My brother thinks to send me a human as my servant? What madness is this?"

The girl stood with a look of shock. It soon drained and she pulled herself up to her full height, which was only about 5'2". "Yes, I am human. And I am an agent for SHIELD." She took a step towards Loki and pressed a finger to his chest. "So don't try any of your games, god of mischief, because my boss won't like it. I'm here to make sure your sentence suits your crimes. Director Fury and I feel life imprisonment is quite lenient for a monster such as yourself."

Loki's snarl turned into an irritated frown and he felt the anger crawl back into his veins. So, Director Fury didn't trust Thor to keep him in check. Fury had to send one of his little lap dogs here to keep his eye on the situation. He brushed the girl's finger from his chest and grabbed her forearm with such force, she let out a squeal of pain. Loki may have had his magic taken away, but he still retained his god-like strength. "Listen, you mewling pest, I may be a prisoner, but I am a god. Lay a finger on me again and I will snap your neck like the twig it is." Loki let go of the girl's arm and both guards rushed into the room.

"Agent Barton, are you all right?" One asked in his husky voice.

Loki's eyebrows jumped up his forehead. Agent Barton? Hawkeye? Last Loki knew, Barton was a man; not this pathetic little girl.

"I'm fine," Barton said, holding her arm and throwing Loki a venomous look. "Let the baby throw his little tantrum."

"Agent Barton?" Loki asked. He wasn't sure why the words escaped his lips.

The girl looked at him again. This time, the snarl was on her face. "Yes. Barton. Waverly Barton. Clint's my brother and frankly, I'm quite pissed you got in his head and messed with him. So, if you don't mind, how about you don't touch me ever again and he won't have to come here and kick your ass. And let me tell you, he is just waiting for an excuse to do so."

Loki was ashamed at his loss for words. He knew he must look pathetic, his mouth slightly opened, eyes wide. He felt furious with himself and his anger only grew when he saw the snarl on Waverly's face twist even more. "Very well," Loki said through clenched teeth.

"Glad you see it my way," Waverly said. "Enjoy your dinner." Venom dripped from her voice and she left the room. Loki heard his door lock and the light footsteps of Waverly leaving the dungeon.

As Waverly walked back to her room, her skin tingled where Loki had grabbed her arm. His touch was icy cold and she couldn't shake the feeling. He had looked at her with such hatred, such evil in his deep blue-green eyes. His eyes made her sick. They reminded her of the icy blue eyes her brother had while he was under Loki's control. The only reason she accepted this job was to make sure Loki didn't escape and try anything sneaky again. Sure, Waverly was a SHIELD agent, but she only worked for the secret agency because her brother had recommended it. She wasn't a fighter, had little to no athletic skills, completely the opposite of her brother. Waverly's main job at SHIELD was to keep tabs on all potential Avengers candidates and report their actions once a week to Coulson. But Coulson was dead now, thanks to Loki, and the Avengers had more or less accepted their role as Earth' protectors. So, now Waverly was pretty much out of a job. Until Fury walked into the debriefing room and asked for volunteers for a special assignment. Watch over Loki and report to SHIELD. She had jumped at this opportunity.

So now, Waverly lived on Asgard, in the palace. Thor had suggested she act as a simple Asgardian maid when she went to monitor Loki. Well, that was out of the question now. Waverly stripped from the uncomfortable Asgardian garb and dressed in a pair of black skinny jeans and a dark purple button-down shirt. She slipped on a pair of light, combat boots, given to her by her brother. She was much more comfortable now.

Sitting on her large bed, Waverly pulled out her smartphone and selected Fury's number from the contact list. His face appeared live on her screen after the second ring.

"Agent Barton, why are you not dressed in your disguise?" The director asked.

"Loki found me out," Waverly answered. "So I figured I might as well dress as myself."

Fury nodded. "And what is the little bastard up to?"

"Thor has him locked in a high security cell in the dungeons," Waverly stated. "His magic has been taken away but he's still strong as hell." Waverly aimed the phone's camera at her arm. "Once he figured out I was human, he didn't play so nicely."

Fury's one eye widened at the bruise on Waverly's arm. "Are you sure you can handle this task, Waverly?"

Waverly put her face back on screen. "Yes, Director. This man made a monster out of my brother. I intend to make sure he pays for his crimes." A dark shadow flashed across Waverly's brown eyes.

Fury looked at her carefully. "Agent Barton, you are not approved to do anything outside of your job description."

"Understood, Director Fury," Waverly assured. "I'm just here to make sure Loki rots for as long as I'm allowed to stay on this planet."

Fury nodded. "Just keep us posted if his status changes."

"Affirmative." Waverly ended the call and pocketed her phone. It was amazing really. She had surrendered the device to Tony and Bruce before she left for Asgard. Whatever they did to the thing made it powerful enough to still contact SHIELD back on Earth.

Waverly slumped back on her pillows. She was not a superhero or an assassin or a spy like the Avengers. She wasn't even a true agent like most SHIELD employees. The complete opposite of her brother. But still, she wanted to do some good. She wanted to protect people like her brother had on so many occasions. Waverly supposed keeping an eye on Loki was the best she could do. And even if she couldn't personally cause him pain and humiliation, she could toy with his head. God of mischief. Well, he was about to meet his match.

Waverly was jolted from her thoughts when she heard a knock at her door. "Come in," she called.

Thor entered the room and suddenly, Waverly's bedroom felt much smaller than it was. The god of thunder towered above her and his voice boomed around the room. "Miss Barton, how did your first encounter with my brother fair?"

Waverly held out her arm. A lovely purple bruise was painted just above her elbow. "Better than expected, actually. You know, he has hands as cold as ice."

Thor had to chuckle at this, but he eyed Waverly's arm apprehensively. "Waverly," he said, his voice now gentle. "Are you sure you are up to this task?"

"Thor," Waverly said in as stern a voice as she could muster. "I may be small and I'm not a superhero, but I am Hawkeye's sister. I'll survive. Clint taught me how to defend myself. I was caught off-guard when Loki grabbed me. It won't happen again."

"Maybe I should accompany you, from now on?" Thor questioned.

"I think that'll just make Loki more pissy. Really, I'll be fine."

Thor nodded and turned back to Waverly's door. "If you need anything, just ask."

"Thank you Thor."

Thor left the room and Waverly slumped back against her pillows. Even though it was only the afternoon, she fell asleep. Traveling between realms, meeting the god of mischief, she was exhausted.

Waverly was awoken around dinner time, by Thor knocking on her door once again. "Miss Barton? Waverly? Are you all right?"

Waverly opened her eyes slowly and rolled from her bed. It was massive really. And covered in silken sheets. Asgard really spared no expense. She opened her large wooden door and stepped aside to let Thor in. "I was just taking a nap. Sorry."

"Quite all right. You've had a rather busy day. Would you like dinner?" Thor offered his arm to Waverly.

"Yes, I'm starving." Waverly laced her arm in Thor's and he led her to the dining room. Waverly was overwhelmed to say the least. The palace was huge. There were so many twists and turns, so many doorways. And everything was so lavish. Nearly all the door handles were made of gold. The floors were marble and all the furniture was made of a shiny metal or gorgeous wood. Rugs were velvet and when the windows had curtains, they were made of pure white lace. Waverly tried to take in everything, but there was so much.

When Waverly entered the dining room, Thor led her to her seat. Waverly didn't realize she'd be eating with the entire royalty of Asgard. She nodded her head respectfully at Odin and his wife, and then took her seat. Again, she was in awe. The dishes and goblets were made of crystal and there was so much food; Waverly's stomach growled at the sight of it. Waverly didn't recognize any of the dishes, but it smelled wonderful.

Odin gave some words of welcome and Thor introduced Waverly to those who had not yet met her. The human girl shook hands with all of Thor's friends, as well as several other important people who's names she could not remember.

Waverly stayed silent through most of the meal. She stuffed herself with some kind of bird that was roasted and downed several glasses of wine. Being only 20, Waverly was just shy of drinking age back home, but here, there was nothing else to drink. Waverly smiled to herself. She was glad her older brother had allowed her to drink with him on several occasions, otherwise she'd be drunk by now. Waverly finished off her meal with some succulent, strange fruit when the conversation turned to Loki.

"Lady Barton," Odin thundered, "Was my son," Odin searched for a word, "Accepting of you?"

Waverly looked up at the god. "Not entirely." She showed off her wonderful bruise. "You tell me?" Waverly felt Thor's warning gaze. She was being too casual with Thor's father. Waverly cleared her throat. "What I mean to say is that he found out I was human. He wasn't too pleased with that fact."

"Are you sure you're still up to this task?" Odin asked.

Waverly suppressed the urge to roll her eyes. If she heard that question one more time, she was going to lose it. But, Odin's words were filled with concern and Waverly felt touched that Thor's father worried about her safety.

"Yes, I am sure. I can handle Loki."

Dessert was served and it was some type of ice cream-like treat. Waverly loved the stuff. It was sweeter than any ice cream she had had on Earth but it was also light. Waverly ate four bowls before her stomach started groaning in protest. Once dinner was finished, a maid laid a covered tray in front of Waverly.

"This for Loki?" Waverly asked. The maid nodded. Waverly turned to Odin. "Loki still gets to eat like a prince even though he's a prisoner?"

Odin nodded. "He is still my son."

Waverly waited for Thor to excuse himself and then followed him through the maze-like halls. The pair descended into the dungeon. It was significantly cooler down in the dungeons and less lavish. They passed several lower security cells. Guards were scattered here and there. Finally, they reached the door that led to the high security cell. Two burly guards stood on either side. They opened the door and allowed Thor and Waverly to pass without question.

"Waverly, there will be no guards directly outside Loki's cell. But I will be there if you need me."

Waverly nodded at the god of thunder and walked down the stone hallway to Loki's cell.

She knocked once but wasn't quite sure why. He was a prisoner, a criminal, he didn't deserve privacy. And he certainly didn't deserve his cell. Waverly unlocked the door and pushed it open. Loki's cell was small and cold but he had a bed with the same lavish, silk bedding that Waverly had. He had a nice wooden table and a small shelf with some things to occupy his time; paper and quills, some books, nothing he could use as a weapon. It was far too nice in Waverly's opinion.

Loki looked up when Waverly entered his cell for the second time that day. Instead of catching him in a restless pace, Loki was now sprawled out on his bed, his arms crossed behind his head.

"Ah, Waverly," he said with fake enthusiasm.

"You will call me Agent Barton. We're not friends, Loki." Waverly walked into the room and let the door close softly behind her. She had the keys secured firmly to a belt loop of her jeans. She sat the tray of food on Loki's table. "Here's you dinner."

Loki didn't rise from the bed. He surveyed Waverly for a moment, curious. She was small; he could snap her spine in two with one hand. But she was brave. The fear from her eyes was no longer present and she gazed upon Loki with such hatred, he felt his cheeks reddening. She wasn't dressed as an Asgardian maid and was instead in ugly human clothes. Loki nodded at her. "You are not keeping up with the ruse?"

"Everyone else knows I'm human. I only wore that to keep you from getting your panties in a twist. But, since you figured it out, I though, 'why bother?'" Waverly explained.

Loki swung his legs from the bed and sat facing Waverly. Her arms were crossed and her brow was furrowed. She looked quite menacing for such a tiny creature. Loki laughed. Humans were so confused. Defiance, determination, strength, they had all these qualities. Really, they were just a pathetic race in need of a true ruler. Loki laughed again and shook his head.

"What?" Waverly snapped, despite herself.

"I am just amused by your defiance." Loki stated. He rose from the bed and sat at the table. Waverly took a few steps back from him, her arms still crossed and her gaze still furious.

"Defiance?"

"Yes."

Waverly rolled her eyes. "You are demented." Loki laughed again. Waverly shook her head this time and walked to the door. "You better show me some respect, Loki, or else I'll make sure all you have to eat is stale bread and water."

Loki opened his mouth to retort, but Waverly slid from the room and locked the door with a deafening click. Loki was once again furious with himself. Waverly had gotten the last word with him twice in one day. He was really starting to miss the gift of his silver tongue. No matter. He was still his mischievous, sarcastic, evil self. Waverly would soon regret volunteering for this job.
