A/N: I forgot to mention that this fic is a slow burn OC/SR. As much as I love Steve Rogers being with Peggy, I wanted to pair him up with someone. Sorry if you don't like that pairing. BTW, my OC won't immediately be with SR. Both characters are a bit more complicated and need a lot of work for them to actually start to like each other besides physical attraction.

This is the first chapter and it's short. I will probably update the next chapter next week.

Enjoy!

Viviana's P.O.V.

The screams of terror and pain as her victims cried for their lives never left her dreams and nightmares, haunting her each day and night. They drove her crazy, her nights wasted in staring at the ceiling of the room as she counted the number of lives she's taken. She always stops after 30 in fear of acknowledging in what she was becoming.

As a lone wolf, Viviana has been used to do SHIELD's dirty work. She spied and eliminated those that got to close to endangering the world, always setting her mind into believing that what she does is for the best. The reality was that Viviana wasn't sure what she was doing was right, ignoring her victims pleads for their lives in order to please SHIELD. It was all backwards, sideways, and upside down, her morals be damn.

Viviana just imagined Zero being disappointed in her, making her feel like scum.

The blinds at her window blocked the streetlights from lighting the gloomy bedroom, which depressed Viviana. Her bedside alarm clock read 3:30, but Viviana wasn't planning to return back into her stiff bed. She got up, slipped into her pink slippers and left her bedroom, heading to the kitchen.

She walked through the empty hallway of the apartment, yawning. A loud shout from outside the building was muffled, two drunk men loudly singing to their hearts content.

She entered the kitchen-living room and took out a water bottle from the mini refrigerator, taking small sips. She was burning up, her cheeks flushed pink and her hair sticking to her skin. The cool water soothed her soar throat, making her feel better after waking from that awful dream.

Her nightmares were never the same, always twisted yet revolving around the truth. They mocked her, using her fear as fuel. Sometimes they were about the people she's killed. Most of the time it was about Zero's death, her still dead green eyes staring at her. Yet, the most frequent of dreams were that of what she feared in becoming, the animalistic side of her coming out and tearing everything she loved into pieces. Nonetheless, she feared sleeping.

A loud knock against the apartment door snapped her out of her tranquil mood and startled her. The bottle was pierced by her sharp nails instantly, water leaking out like a river. She quickly dropped the bottle into the sink lightly, her senses picking up as she crouched into a low position.

Her hearing senses detected a solo man outside of her apartment, his shoes tapping against the floor impatiently.

"Viviana? It's Phil. I know you're awake. Open this door." Phil loudly said, knocking again.

Viviana sighed, got up and rubbed her eyes. She went and opened her door, seeing Agent Phil Coulson standing impatiently in his black suit.

"Finally." The man said and he made his way inside, ignoring the fact that Viviana didn't invite him in. "I wasn't sure you'd be awake, but then again, you never sleep." Agent Coulson said. He examined the dark apartment, barely being able to see anything. "Christ, at least have the lights turned on." Agent Coulson muttered under his breathe, going ahead and flipping the lights switch. The lights harshly blinded Viviana and she instantly blinked multiplied times as her eyes got adjusted to the lights.

"Hold up now. Who's apartment is this? Because the last time I remember is that I sleep here." Viviana snapped at Coulson, arms crossing under her chest.

Agent Coulson rolled his eyes and frowned at the current state of the apartment. "Yeah? Well who's paying for the place?" He said rhetorically. He glared at the coffee stain on the light brown couch. "Seriously?" He unconsciously said. He sat down on the kitchen barstool, leaning back comfortably on the counter.

Viviana glared at him. "Are you my mother now? If not, get the fuck out." She said.

Coulson frowned, looking up and down at Viviana. She was dressed in her black tank top and black shorts, feet tucked into pink slippers. Her hair was ruffled, lose strands sticking out of her loose braid.

"Is that how you speak to your mother?" Coulson asked in a snarky tone.

Viviana smirked. "Yeah, I do. But she always washes my mouth out with soap after."

Coulson chuckled and shook his head, settling into a light mood. Viviana then made her way back into the kitchen, seeking for something to eat our drink in her refrigerator.

"What are you here for?" Viviana asked. She ignored the stinky Chinese food, and opted to take out the carton of low-fat milk.

Coulson sighed, slipping a manilla folder over the counter towards her. "The Avengers Initiative has been activated." He stated seriously, seeing Viviana's face as it twisted into disgust.

"No." Viviana immediately said.

Coulson rolled his eyes. "I'm not asking you. Fury is bringing everyone in. It's all hands on deck." He said.

Viviana studied the man curiously, drinking directly from the carton of milk. A milk mustache was left behind on her lips, and she quickly licked it off.

"But I'm already deep in an undercover mission, which, by the way, you're not supposed to be here." She said. She moved to open the file, looking through the mission debrief.

"Yeah, I know. Fury's taking you out of this one, though. He wants the Avengers Initiative to pick up for this mission. Says it's something only you and the others can do." He said. Viviana looked up, her eyes connecting with Coulson's blue eyes. She wasn't sure what she was searching, but whatever it was, she found it.

"When did this happen?" Vivi asked, looking back down at the file. She understood that the situation SHIELD found themselves in was definitely serious for the agents, whom both felt the danger and anticipation for what was to come.

"Just yesterday. Was ordered to come and get you and Stark."

"As much as Fury loves his plan of action against enemies, I must say that nothing will go according to his plan."

"That's fine with him. As long as we get the guy."

Viviana turned away from him, putting down the carton on the kitchen counter. She smirked, feeling the thrill for a fight.

"Good enough for me than. Want some coffee?"
