The fall wasn't long but the impact with the solid ground was hard. Natasha landed on a fallen tree branch; the air was knocked out of her lungs. She gasped, tried to fill her lungs with much needed air and then breathed deeply. Stunned, she tried to get up but only managed to raise to her knees, still gasping for air. Her ribs hurt a little and she tried to clear her head out of the dizziness. A few feet from her were five H.Y.D.R.A. soldiers who seemed to be out of it as well. The spy checked her surroundings and saw trees and snow as far as the eye can see, no apparent building or house, nothing but trees. She knew that the soldiers were going to get up soon so she forced herself to get on her feet before them.

"It's been a long day. Hell, it's been a long week, guys. Are you sure you want to do this? You may as well choose life and run." laughed the redhead.

Five minutes earlier. Denali forest, Alaska.

It was a perfect day so far, nothing alarming in the Denali territory. Kate was not in a prankster mood; Irina was her soft self and Carzar (Carmen & Eleazar) were cute as always. The three sisters decided to go on a hunt, the mated couple not coming with them this time.

Tanya stopped in the forest to breathe the air and smelled a moose not far from her. Venom pooled in her mouth and she swallowed thickly, running silently towards her meal. Kate and Irina were close to her, having their own target. Tanya climbed in a tree near the moose, planning to drop on its back. Suddenly, a noise attracted her attention. She decided to keep the height to her advantage and stayed on her tree branch.

"Kate, Irina did you hear that?" the strawberry blonde whispered, loud enough only to be heard by her sisters.

"I did," responded Irina, quickly joining Tanya in the tree. "Did you see anything?"

"Some sparks of sorts, maybe?" whispered the older vampire.

"Some action! I was going to die of boredom at this point." said Kate with barely contained excitement. "Move, Irina! I want a good seat."

The said blonde huffed and made room for her sister. Tanya groaned and hit Kate on the back of her head, beckoning her to pay attention.

A red circle surrounded by sparks appeared horizontally at approximatively six or seven feet off the ground. A noise that sounded a lot like a gunshot echoed in the woods and seconds after it, bodies cladded in black dropped from the circle and crashed on the snowy ground with audible grunts.

"Huh, that's new." chuckled Kate. She hunched over, hands on her knees and legs swinging with glee.

They could decipher six bodies; they seemed human at first sight and smell. Five men were in black uniforms, mercenary sort of clothes and some were gripping a leg or arm as if in pain. The sixth body was a woman in what seemed to be a black catsuit with blue lines on it and weird bracelet on her wrists, short bright red hair forming delicate curls above the shoulders. The woman was the first to get up after coughing and catching her breath.

"It's been a long day. Hell, it's been a long week, guys. Are you sure you want to do this? You may as well choose life and run." said the woman in a raspy voice and with a slight accent.

"Do not intervene, we don't show that we are here except as a last resort." said Tanya, without taking her eyes off the scene. Irina nodded and Kade didn't respond but didn't move either.

The men were beginning to rise to their feet when the fight began. The woman jumped on the first man and used him as an anchor to kick the one behind him, sending him to the ground. She rotated on the first one and quickly jabbed her elbow on his head and electrocuted him with her bracelet. She ran to the remaining soldiers not without slamming her foot on the head of the fallen one she kicked seconds ago. One soldier took out his gun but too late, the redhead kicked it out of his hand then sent a kick to his head, he dropped on the ground. Before she could react, a man pounced on her, sending them both to the ground. He hit her in the ribs and she let out a pained grunt before reversing their positions and raising her fist to hit him but the last man standing caught her arm and twisted it behind her. She managed to take hold of his right arm an send him flying above her to crash on his colleague.

"Can't we go? I feel like an old grandma watching and judging people from a bench in a parc." complained Kate. "No." was her only response, causing the blonde to huff angrily.

They watched as the woman took several steps back and the two men rose from the ground.

"Is it me or is this redhead really beautiful and kicking their asses like it's a walk on a Sunday morning?" Kate said balancing on the branch as she watched the fight. Her sisters just hummed in agreement.

The redhead rolled her shoulders before running again, hitting the first soldier in the throat multiple times, making him gasp for breath. She jumped on the second one, wrapping her thighs around his neck and squeezing before snapping his neck with her hands.

"Ow, that has to hurt." commented Kate again as if in a movie theater, popcorn missing but still.

The redhead was now left with the last soldier who moved his hand to the gun strapped on his thigh, one hand still at his throat. The woman moved rapidly, rolled on the ground and picked up the fallen gun of the goon that she kicked earlier, she removed the security and shot three times, emptying the clip and killing her opponent even before he could take the security off of his gun. The first man who was knocked out was slowly starting to wake up a few feet away from her so she took a knife out of her boot, drew back her arm and thew the blade, hitting him square in the chest.

"Well, that was fun. Thank you for your cooperation." muttered the redhead. She took her hand to her earpiece and clicked on it. "Steve, do you copy? Stark?" No response. "Fuck."

The three vampires still watched like hawks, not making any noise and not taking their eyes away from the lady even for a second.

"Dr. Strange? Dr. Strange! Where the hell did you send me? Fucking men with red capes." complained the redhead.

She threw a look around, still not seeing anything out of the ordinary so she leaned forward and searched the bodies. She found a single full magazine and replaced the empty one.

"I think we can show ourselves, see if she had a good reason to kill those men and she can tell us where she's from." announced Tanya, the coven leader. The woman had her back to them and the blonde jumped from the tree silently, softly approaching as Kate took the left and Irina stayed in the tree.

Third person pov

Natasha could feel the baby hair at the base of her neck standing. She had a feeling that someone or something was watching her. Suddenly, she took the gun out of the holster and turned around, pointing it at the blonde woman approaching.

"Do not come any closer or I'll shoot." stated the spy. The blonde immediately stopped, even if a bullet wouldn't do her any harm.

"You are on the Denali territory, what are you doing here? Who are you?" demanded the blonde with an authoritative voice. The redhead narrowed her eyes, remarking that the blonde was unnaturally beautiful, with weird golden/yellow eyes, really pale skin and seemed to have appeared from nowhere "hardly human" she thought.

"Oh god, isn't Denali in Alaska?" said Natasha, slightly exasperated.

"Yes, it is. Where did you come from?" asked Tanya, narrowing her eyes in suspicion.

"Great," the spy huffed. "A weird dude appeared and one thing leading to another, poof here I'm. Just another day at work."

"Why did you kill those men?" said the blonde, getting angry at not having any questions answered. The redhead responded with a sigh.

"They were responsible for the explosion and attack in New York. Didn't you see the news or something?" Casting a glance around her, she added. "Maybe not."

Tanya spotted Kate behind the redhead, supposedly trying to surprise the woman to take her gun? She wasn't sure, Kate was always unpredictable.

"Worry not, I'm not one of the bad guys." Natasha said, trying to see if the woman was a threat or not. She saw the blonde cast a glance over her shoulder and, trusting her instinct, turned around and throwed her last widow's bite behind her. It hit the chest of another blonde whose hand was extended towards her. The woman stared at the device on her chest before going rigid and dropping to one knee from the electricity coursing through her body.

"Kate!" yelled Irina, jumping from her hiding place and running to her sisters.

"How many are you? What are you?" yelled Natasha, taking a few steps back from the blondes and still gripping her gun, pointing it at the two blondes standing.

"Calm down, there's only the three of us. Put the gun away, we will not attack you if you say the truth." said Tanya calmly.

"Oh my, that's a cool trick! I have something similar, do you wanna-" still on one knee, Kate cut herself short, her golden eyes connecting with green ones as breathed out. "Mate."

Natasha watched as the golden eyes of the blonde she just electrocuted turned a dark caramel, emotions swirling on her face, joy, longing, admiration, ...something else?

"Oh shit." said Tanya, eyes wide with choc.

"Mate? Are you some kind of creature?" asked the redhead, eyes going from the caramel ones to the strawberry blonde who just spoke.

"Uh, we're...vampires." Tanya said hesitantly.

"Vampires." the redhead repeated.

"Yes. But we're "vegetarian", uh, that's a little vampire-joke really," the blonde said with a awkward laugh. "But essentially we don't drink from humans."

"Mate!" said Kate again. She rose herself off of the ground and with a goofy smile, took a step closer to the redhead.

"No, Kate, that's not a good idea! The lady just electrocuted you." said Irina, running to stop her sister whose current mission was to go to the redhead and probably try to kiss her, hug her, or worse.

Said Kate began to growl and snarl at her sister. Natasha watched with attentive eyes, her instinct telling her that the woman was not a direct danger to her. She could feel a little something in her body but could not place a finger on what it was. Just as the blondes were beginning to shake each other she put her gun back in its holster.

"What are they doing?" she asked, taking a step closer to Tanya.

"How to put this... Vampires have what we call a mate, like a soulmate if you will, a one and only. When a vampire sees his mate, he knows instantly when looking in their eyes." explained Tanya.

"Hmm. Like love at first sight?"

"Yes, you could say that. Only on a deeper level." the strawberry blonde smiled and then added "I'm Tanya Denali. Those are my sisters Irina and Kate."

Irina was still holding Kate back but it was difficult as her sister was not quite herself at the moment. Just before the angry blonde shocked her sister, the redhead interrupted.

"Kate, was it?" she said softly, gazing at the eyes of the growling blonde. The woman stopped immediately and nodded with wide eyes, pushing Irina away.

"She's lost in her instincts. Her vampire side wants to protect you and be near you."

The redhead nodded and took a few steps closer to Kate. The blonde was frozen and breathing deeply, watching her every move. Natasha closed the distance and softly placed a hand on the blonde's cheek, gasping at the cold skin. Kate immediately leaned in her touch, breathing in her mate's scent.

"Do calm down, little vampire." she ordered. The blonde blinked a few times and, after a few seconds, seemed to come back to herself slowly, her dark eyes becoming again a dark caramel.

"W-what's your name?" asked the vampire trembling slightly. She took the chance to really look at her mate, seeing her beautiful features. Green eyes, well-shaped eyebrows, pulpy red lips, sharp jawline, beautiful curly red hair. And that was just her face, Kate couldn't admire her body quite yet. That would be inappropriate. Wouldn't it? The redhead raised an eyebrow at the stutter but didn't comment.

"Natasha Romanoff. Pleasure to meet you." smirked the spy.

"Natasha" repeated the vampire, admiration in her voice. She reached out to touch the spy and, not receiving any complains, slowly slipped an arm around the redhead's waist. Before she could hug the woman, a single finger poked her in the chest.

"Not so fast, Speedy Gonzales." Natasha said with a smirk. She allowed the arm to stay around her waist and turned around. The vampire whined behind her.

"Do you have a phone?" she asked Tanya.

"Yes, at our house." the coven leader said. "Kate, you were a succubi for heaven's sake! Have some class!"

Natasha raised an eyebrow "Succubi, you say? I'm more like a Black Widow kind of gal." she said with a smile. "Anyway, can we go to your house? I need to make a phone call." The adrenaline rapidly leaving her body, she realized it was cold, like freezing cold. Every breath she took came out in a cloud and she began to shiver.

"Yes! I can take you there in a matter of seconds." responded Kate proudly. Natasha scoffed and throw a glance at the blonde still holding her.

"I can walk."

"O-okay, but it's freezing! The house is twenty miles from here!" she argued.

Natasha pushed the blonde away. "I'm Russian, I don't get cold." Kate watched with an open mouth as the redhead began to walk away adding a sway to her hips. Venom pulled in her mouth and she swallowed thickly. "Well, that was hot." she muttered, hearing her sisters laugh under their breath.

"Miss Romanoff?" Irina called. Natasha turned and the blonde continued with a barely contained smile. "This way." she said, pointing the exact opposite direction.
