AN: So I love the Darcy/Loki pairing and currently have a fic underway, but I got to thinking…Darcy's always so strong and sassy, what if I did a fic where she was also kind of…weak? This fic puts Loki as a bit of a jackass, so consider yourselves warned. Also, not sure if T or M, so M for good measure. Enjoy!

It was nights like this that made Darcy thankful that she and her parents lived in an apartment building full of old people. While her parents went out to their parties, she didn't have to put up with trick or treaters, or deal with middle and high school children TP'ing their lawn. Instead, she could spend Halloween the way god intended- knee deep in the popcorn that jumped from her bowl when something startling appeared on her TV. This was the seventh consecutive year she had participated in her tradition, and she had no plans of stopping.

But divine interference had other plans.

There was a knock on the door, causing more popcorn to jump from the bowl. Strange, Darcy thought. I didn't buzz anyone up.

"Must have the wrong apartment," she mumbled, pausing 'Shark Attack 12' and walking to the door. She opened it and craned her neck back to look into a stranger's eyes.

"Trick or treat," he smiled, a mischievous glint in his green eyes.

"Sorry buddy, I don't have candy."

"Good. I had something sweeter in mind." He grabbed her shoulders and pushed her further inside the apartment, closing the door. Darcy turned and reached for a kitchen knife, a few feet away from her, but it slid further away. The man grabbed a handful of her curls, pulling her back against him.

"What do you think, Darcy," he whispered in her ear, "I'll play the trick, and you'll be the treat." She didn't even have time to tear up before the man spun her, lifted her small frame, and set her down roughly on the small kitchen table. Darcy kicked him in the stomach and crawled backwards, falling off of the table. She scrambled to her feet and ran down the small hallway to the right, running into her bedroom and slamming the door. She could hear the man's laugh grow louder as he approached.

"Hiding will do you no good, Darcy."

"Who the hell are you?" she shrieked through the door.

"All in good time." Then the apartment went silent. Darcy could hear nothing over her own heartbeat.

Is he going to get something to break down the door? she wondered. She'd seen enough horror movies to know he'd either be back with something dangerous or he was waiting for her to open the door, checking if he'd left. What do I do? she racked her brain, glancing around. Her eyes fell on the nightstand a few feet away from her. She leaned to the side, trying to keep her weight mostly in front of the door, and tugged at the small chest of drawers. After a few tugs it slid to her, a lamp falling and breaking on the floor. The door shook violently as the intruder attempted to break it down for seven seconds, falling silent once more.

Darcy's eyes were blurry with tears, but she scooted the nightstand into her place, running to the window. She pulled the curtains aside and screamed, seeing the man standing on the sidewalk below. Were there two of them? He smirked as Darcy pulled the curtains closed. She turned in circles, trying to remember what the movie survivors did.

The bed.

She opened the closet door and pulled a sweater sleeve out, closing the door again. In the bathroom, she pulled the shower curtain closed and rumpled the rug. Once she was finished, she slid under the bed and waited, trying to calm her breathing.

A few painfully silent minutes passed before her bedroom door turned to large splinters. How the hell had he managed that? Sure the man was tall, but his body didn't look that powerful.

"Darcy," he called softly, a smile audible in his voice. Oh god, she thought, that sick bastard's enjoying this.

He walked into the bathroom, turning on the light. Darcy could hear a ripping and a small crash, which she assumed was her shower curtain. His heavy footsteps then walked to the closet, opening the door. It rained clothes for the following minute as he searched for her. He stepped out of the closet.

"I know where you are." Tears streamed from Darcy's eyes. This wasn't a horror movie. She wasn't going to get away.

The man knelt and reached under the bed, grabbing Darcy's arm and yanking her out. He easily lifted her to her feet and pinned her against the dresser. She struggled against him, but he easily held her in place.

"I knew I picked you for a reason," he purred at her, his eyes practically glowing. "I knew you'd make it interesting."

"Please don't do this. Please," she choked on her tears, "I haven't don't anything to you."

"Oh but you will." His expression grew dark.

"I won't, I promise. I swear-"

"You'll promise you'll swear what?" he hissed.

"I won't do anything. If you leave me alone, I swear I won't hurt you or whatever it is you think I'm gonna do."

"Swear it on your life," his voice was a growl- predatory and rigid.

"I swear it," she cried, her voice a high-pitched whisper.

And he was gone.

Darcy glance around with shaking breaths, expecting him to be hiding somewhere in her room. He was probably deranged enough to give her a false sense of security and then rip it right out of her. But several minutes passed and he never appeared. Darcy finally mustered up the courage to move.

That had been two years before Thor fell to Earth…

~*3 Years Later*~

It had been a year since Thor had arrived, shaken up their lives, and disappeared. Jane was an obsessive wreck, Eric was always away on S.H.I.E.L.D. business, and Darcy was, well, Darcy.

On this particular day, Darcy was being Darcy in Jane's new and improved laboratory. S.H.I.E.L.D.- true enough to their promise- had not only returned all of Jane's equipment and research, but had given them some substantial financing to expand. Darcy often found herself in the observation room- a small room full of TV monitors through which she could watch the entire lab. There were also a few unused monitors which she occasionally used to watch movies.

It was Halloween, and Darcy was tucked away in the observation room watching 'Shark Attack 14'. She was getting back on track with her tradition after skipping a few years.

On screen, a group of coeds was being savagely ripped apart by a swarm of genetically altered nurse sharks when the power went out.

"God dammit," Darcy mumbled.

"Hello Darcy." She froze. It had been three years since she had heard his voice, but she remembered it perfectly.

"No hello?"

Darcy turned slowly, shaking, and stared up into his green eyes. His hair was longer, but everything else was the same.

"You don't look happy to see me," he mused.

"What do you want?" she squeaked.

He took a step toward her, "I need your help."

"Why would I help you?"

In a heartbeat, the man leaned down, cornering Darcy, "Because I'm not giving you a choice, Darcy." She shivered when he said her name.

"Don't say that."

"Don't say what?"

"My name. I don't want you to say it."

"Why not?" he smirked.

"Because…it sounds evil." He laughed and Darcy cringed.

"Why do you need my help?"

The man straightened, "I'm afraid I've brought too much attention to myself recently. I need to, how do you people say, lay low?"

"I don't think so," Darcy leaned back, "I'm not gonna be your accessory for…whatever it is you do."

"Oh you will," the man's eyes flashed like a cat's. "You swore on your life."

"I swore not to hurt you, I didn't say anything about helping you."

"But you'll find that unbreakable vows can be manipulated. If you don't help me it will be the same as hurting me, and you will die."

"Unbreakable vow? This isn't 'Harry Potter', dude," Darcy's eyes narrowed and her volume increased.

"When you swear to a god, you stake your life on your word."

"God? Don't make me laugh." After their last encounter Darcy had struggled to rebuild her self-confidence, but she had taken several self-defense classes and carried multiple cartridges for her tazer. And when in doubt, she always fell back on her sass.

The man's expression grew darker, "Do not test me, Darcy Lewis." The air began to move, swirling around them.

"What are you doing?" Darcy's voice shook.

"You will assist me, or you will die." A blade-like shard of ice, crackling with electricity, formed in the man's hand. "What'll it be?"

Darcy opened the door to her cozy villa, leading the green-eyed man inside. I can't believe he's invading my house AGAIN, she thought. She felt numb. She stopped in the middle of the living room and watched him stride around, examining random things like her collection of ballerina figurines on the mantle.

"This will suffice," he muttered. "Where are my sleeping quarters?" he glanced at her expectantly.

"You're looking at them. You can have the couch," she spat.

"I think not," he bristled. "I know that all of these villas have at least two bedrooms. Show me to mine."

Darcy glared at him, "If you already know it's here why don't you just find it yourself?"

"Because I want you to show me," he smirked.

"I'm already going out of my way to help you," Darcy crossed her arms, "Don't expect special treatment. We're not friends. Hell, I don't even know your name."

"You may call me Loki."

"Oh, may I? Thank you so much," she glared at him before walking to the kitchen to get a drink. Loki followed her. He watched silently as she poured a glass of iced tea and began to take a sip.

He then proceeded to tip the glass, pouring the tea all over Darcy's face and down her front.

She spluttered and stared at him, mouth open and eyes blazing.

"What the hell was that?" she screamed and threw the glass at him. He dodged it easily, letting it shatter on the wall behind him.

"That was just a bit of fun," he replied coolly.

"What is wrong with you? Do you get off on shit like this?" she demanded.

"And by that you mean-"

"Invading people's homes, ruining their lives, shaking out any sense of security they managed to rebuild."

"Ah, then yes, I do."

"You make me sick."

"Some day, Darcy-"

"I told you not to say my name-"

"-You'll learn that we can't all be heroes. The world needs its villains- like me- and its victims- like you."

"I am not a victim."

"They may say so in your self-defense classes, but you and I both know that you're just a scared, weak little girl."

"I'm going to kill you," Darcy shook her head, trying to not believe his words. They were far too similar to the voice in her head that had been whispering how helpless she was for the past two years.

"Causing me intentional harm will kill you instantly."

Darcy glared daggers. She wasn't sure if he was right. He had put on quite a show that evening, and she knew that gods did exist, but she didn't want to believe that this monster could actually wield that kind of power over her.

"It just might be worth it," she turned and left the kitchen, walking to her room to change out of her wet clothes. Her mind swam as she peeled off her sweater and tank top, standing in just her jeans and bra. She buried her face in her hands, trying to clear her mind of this Loki person and everything he had done.

"Three years, and I can't get over it." She looked at the mirror above her dresser, staring at her reflection. "You make me sick." Darcy changed into a pair of modest pajamas; baggy sweatpants and a loose t-shirt, and climbed into bed. She wasn't sure if she would be able to sleep that night, knowing what was in the other room. She curled up into the covers, clutching her blanket tight around her.

The digital clock on her nightstand flicked through numbers as she lay there, heart beating in the ears that strained to hear the monster in her house. Would he attack her again? Or maybe just kill her in her sleep? Maybe that would be best, she thought, I wouldn't have to worry about him anymore

She didn't know what time she finally fell asleep, but she knew that she woke up far earlier than normal. Darcy never woke up before eight A.M. She fumbled out of her blanket cocoon and opened the door, sneaking down the hallway as quietly as possible. Loki wasn't in the living room, so he was either in the kitchen, the guest room, or not in the villa. She wouldn't have expected him to actually stay in the guest room, as it was full of storage boxes and didn't even have a bed- if she ever had overnight guests they were generally too drunk to care where they slept. But once she reached the kitchen, she was back on edge. There he sat, looking well-rested, at the kitchen table. He was reading the newspaper, sipping coffee and taking an occasional bite of toast. If she didn't know any better, she'd think he was a normal person.

But she did know better.

"There's coffee," Loki said, eyes never leaving the newspaper.

"I can see that."

"And I made toast."

"Obviously."

"Oh come now, don't be so frigid." He turned the page.

"Don't you dare tell me what to do," she spat. That caused him to look up.

"I overlooked it last night because I expected you'd be surprised to see me, but don't make the mistake of thinking you can speak to me so rudely."

"I've had enough of this 'holier than thou' regal formal shit," Darcy advanced toward him. He folded the newspaper and set it down. "I don't know where you're from, but it's not acceptable to treat anyone like this."

"I'm from Asgard, actually, and I treat people however I like no matter where I am."

"Asgard?"

"Correct," he took a sip of coffee.

"So you know who Thor is, right?" Loki paused, and Darcy continued, "Because I know Thor, and he's a great person. He's nice, and he always does the right thing, and you should be ashamed that you don't act like him."

"Like I said," he set the mug down, "The world needs its villains."
