Disclaimer: This is self explanatory but I still need to say it.

I do not own any of the songs used in these one-shots

I do not own any of the characters from the Avenger Movies (or any other Marvel Movie) and Agents of S.H.I.E.L.D. If I did, Romanov and Banner wouldn't be a thing, and if they were, it would have been done much more realistically than in Agent of Ultron. I don't list characters in here because for all I know they may never be used in my writing.

Some of these chapters might be set in an AU setting. If that happens I'll try to give a warning. Each chapter is a one-shot. The pairings are bound to mix up, personally I'm a Clint/Tasha shipper but I might surprise you.

Bad Blood- By Taylor Swift

'Cause, baby, now we got bad blood

You know it used to be mad love

So take a look what you've done

'Cause, baby, now we got bad blood

Hey

Something hot and cold flashed through him the moment he saw the familiar swish of red. For a long moment he didn't want to believe that it was her, that it was some other woman with vividly red hair. But Clint knew from the twist in his stomach and the throbbing along his right bicep that it was her. That it was Natasha. He was hot and cold, with anger and loss, hatred and sadness. With the urge to confront her and the urge to hide back in the shadows before she confronted him.

They were the best of friend, the greatest duo in S.H.I.E.L.D.. Emphasis on was, now she was a total stranger to him. A deadly stranger. And in all of Clint Barton's years of training, his instincts told him to never trust a stranger.

He did once. And look where that got him.

Now we got problems

And I don't think we can solve them

You made a really deep cut

And, baby, now we got bad blood

Hey

Clint barely escaped with his life, he considered himself extremely lucky to have survived. He'd seen so many other agents, young and old, die at their hands. At her hands. And they almost got him as well, except he got away. Albeit, with more injuries than he cared to admit.

His calloused fingers traced the scar along his right bicep, long and jagged. It was impossible to miss, it's milky white color stuck out sharply against his slightly darker skin tone. It was one of the most recent scars that littered his body, one of the newest in his collection. But what hurt the most was that Natasha gave him this one.

Did you have to do this? I was thinking that you could be trusted

Did you have to ruin what was shiny? Now it's all rusted

She matched her stride to his pace, a blank mask wiping her face clean of any emotion. Clint could only guess what she was feeling, what she was thinking. If anything, he could guess that she saw him as an idiot. He could also guess, though with uncertainty, that she was nervous.

"Don't worry," He told her, "Fury may be a stubborn son of a bitch, but so long as I'm there he won't shoot you dead."

"How can you be so sure?" Her voice was as blank as her expression and hollow. Her green eyes bore into his grey eyes, filled with skepticism and disbelief.

"Just trust me," Clint says, "I have good instincts. It might take some hard persuading and some stubborn arguing but I will get him to see the good in you. I will get him to see you as someone more than some killer for sale."

Her green eyes narrowed into slits, something Clint wasn't sure to be a dangerously bad sign or not. But it was true, she was a killer for hire. And often for the worse kinds of people, the wrong people. She didn't lend her skills and resources to the same people that paid Clint.

"There is no good in me."

"Then why are you still here? We both know you could get out of those handcuffs fairly easily," Their gaze fell onto the handcuffs that held the Russians wrists together, in front of her stomach. They both knew that getting out of those wouldn't be that difficult for the Black Widow. Clint smiled after a few moments, pausing in the hallway, "If there's no good in you, if you didn't want to change your ways, then we wouldn't be where we are right now. I believe you want to change. I know you won't hurt me because you would have tried to kill me already."

Without another word, they turned their gaze from each other to Fury's office door and stepped inside.

They all told him to not trust her. Fury, Hill, Coulson, every S.H.I.E.L.D. Agent questioned his sanity and warned him that Natasha Romanov was not to be trusted. That she would rather kill you than trust you, that she was manipulating Clint so she could get intel on them. No one trusted her. Except him.

They were the greatest duo throughout S.H.I.E.L.D., no one worked better together than them. Admittedly at first, they didn't quite get along or agree with the techniques of their partner. Clint didn't agree with her methods, mostly those concerning her using sex on her targets, and Natasha didn't understand why he preferred such an outdated weapon instead of some of the best guns offered to him. It annoyed, no, it angered her that he used such a primitive item.

But through hard work, through listening, through keeping each other's secrets, through hours of training, countless missions and captures they'd managed to work out all of the kinks in their partnership. They knew each other more or less like the back of their hands. Their strengths and weaknesses, their secrets, the things that torture them in their nightmares. They knew it all.

They had the perfect partnership, were the perfect team. But that's ancient history now.

Did you have to hit me, where I'm weak? Baby, I couldn't breathe

And rub it in so deep, salt in the wound like you're laughing right at me

Oh, it's so sad to think about the good times, you and I

Her lips were moving, Clint could see that. But he couldn't hear a word of it. All he could do was read her lips and her hands when she bothered to use sign language. Her red lips moved in rapid fire, in which language Clint couldn't tell because he was a shitty lip reader when it was anything but English. She'd taken his ability to hear, used some weird high tech EMP that just shut off his hearing aides. He didn't know why she didn't just destroy them, but he didn't bother to ask. That wasn't his biggest concern. His biggest concern was that she had an arrangement of knifes, all in different sizes and styles, and when you lose one of your senses the others were heightened. And without his sense of hearing, his other four senses were heightened. His sight, his taste, his smell, his ability to feel.

Natasha approached him quietly, holding the knife right under his eyes before she started to dig the metal into his flesh. The pain that followed crackled and stretched through his nerves, a pain worse than what was usually experienced. The blood ran freely across his skin, dripping onto the floor beneath him and absorbing into his shirt. She watched as the pain registered across the archers face, she dug her knife deeply into his arm, letting his blood soak the very tips of her fingers.

"I TRUSTED YOU!" Clint screamed, although he wasn't quite sure if the words left his mouth or not. But Natasha heard them and she stared at Clint with a blank expression. Her hands immediately started to move, forming the shapes in sign language.

'You were wrong to trust me Agent Barton. All it did was bring you here, to your demise. Your instincts are not as good as you believed them to be. Everyone in S.H.I.E.L.D. was a fool to trust me.'

Clint stared at her, the translation hitting him like a sack of bricks. But before he could try to respond, before he could try to scream and make his mouth move to form words, she dug another knife into him. Through skin and muscle, cutting his veins and twisting it so he felt as much pain as possible. Pain so intense, it felt impossible to do anything but scream. Not even breath, just scream until the body gave out to pain.

'Cause, baby, now we got bad blood

You know it used to be mad love

So take a look what you've done

'Cause, baby, now we got bad blood

Hey

Clint turned, deciding it was better to head back to the tower than take his chances against the assassin. For all he knew she was here looking for him, to finish the job. And if that was the case he'd rather have a man in a metal suit, a super soldier, god, and Hulk backing him up in that fight. It wasn't cowardly, it was smart and strategic. That way, even if she killed him, there'd be someone to finish the job and do what he couldn't nearly ten years ago.

But she spotted him, she recognized that hair and those eyes anywhere and weaved her way through the crowd towards him. But she saw him leaving and picked up the pace, struggling with the decision on whether or not to shout his name. It was likely he'd run. Hell, given the location and situation of things, he'd more than likely run. As far as she knew, he wasn't armed. And as far as he knew, she likely was.

"Clint!" She dared to call his name but he was already out of the coffee shop, already making his way as far from the StarBucks as possible in order to lose her.

She ran after him, catching up to him fairly easy. As she neared him, she sprung onto his back, her unexpected weight sending them both crashing onto the pavement. The moment his knees hit it, she threw her weight to the side so they landed halfway into the alley. Using every once of strength in her upper body, she rolled them all the way in until they were a few feet away from their exit and entrance. Clint threw his elbow unexpectedly into her stomach, catching her off guard long enough to throw her off.

Now we got problems

And I don't think we can solve them

You made a really deep cut

And, baby, now we got bad blood

Hey

Natasha rolled onto her side as she hit the ground, her hand wrapping around Clint's left ankle as she scrambled to his feet. She pulled the leg out from under him, sending him sprawling onto his stomach. Before he could get back up again she was already positioned onto his back, her knees jabbing into his shoulder blades, pinning his arms down by the wrist. She could feel him struggling beneath her and it was only a matter of time before he threw her off.

"Stop struggling Barton," She hissed, her breath tickling the back of his neck tightly. She had leaned in a bit too close, a fact Clint was now becoming aware of, "I'm not here to kill you."

"Really? Because if I didn't know better you're either here to kill me or-" He stopped as it finally dawned onto him, on why she was here other than to kill him.

He jerked his head back, a slightly audible crack resonating between them when skull met skull. It disoriented Natasha enough for Clint switch their positions, pinning her smaller body beneath his.

Did you think we'd be fine? Still got scars on my back from your knife

So don't think it's in the past, these kinda wounds they last and they last.

Now did you think it all through? All these things will catch up to you

And time can heal but this won't, so if you're coming my way, just don't

"Are you fucking kidding me?" Clint sounded like he was shouting, but his voice never rose from the quiet yet angry volume he used. The anger blazed like a triumphant fire in his eyes as he stared down at Natasha Romanov. She watched him silently as he spoke, "You really thought you could come running back to me like this? After all you did? You did worse than added new marks to my skin Natasha. Or should I call you Natalia?"

"That's the name of a past me," She never yelled, she never spoke in the same angry and hostile tone that he was expressing to her. She stayed calm, because otherwise it make Clint all the more angry at her.

"You think we can just push that betrayal behind us and start over like it never happened? You think I'll take you back? You did more than physically scar me, Natalia," He spat her real name venomously, "You did more than that. You hurt me much deeper, damaged my ability to trust. You destroyed us. And we will never recover. We will never go back to how we were."

"I left them for real Clint," Natasha stared at him, trying to find some compassion in his eyes. The same old Clint who had such faith and hope in her. But that Clint was dead. The Clint that would hesitate to kill her was gone, "I missed you."

"Don't pull that crap Romanova."

Natasha pursed her lips in a thin line, slightly frustrated and at a lost of what else to say. She opened her mouth to speak again when Clint interrupted her, venom in his words.

"Suppose I did take you back," It was a mere hypothesis, "Did you even think this all through? What about the Red Room Natalia?-"

"Don't call me that."

But Clint continued, as if she never interrupted him, "What about the KGB? You left them for real this time, all those missions where you faked being an ex-member... Before that was part of your plot remember? Now they'll really be coming for your ass and I am not letting you drag me down with you."

Clint glared down at her his grip tightening on her wrists. The entire time though she never struggled that much beneath him, and she was more or less still now, staring into him. He stared into those green eyes, the emerald orbs he thought belonged to a woman he could love.

He got off of her in one fluid motion and stood, making his way out of the ally, "Keep me out of your shit problems."

Oh, it's so sad to think about the good times, you and I

'Cause, baby, now we got bad blood

You know it used to be mad love

So take a look what you've done

'Cause, baby, now we got bad blood

Hey

'He's such an idiot,' She mused to herself, leaning against the bar counter with a beer in hand. Beside her stood Pepper, a glass of wine perched in her hand as they watched the guys. The five men sat on Stark's expensive couches with a stack of beer cans either on or underneath the coffee table.

They sat hunched over a game of monopoly, getting drunk off their asses. For some inexplicable reason, Tony thought it be fun to turn it into a drinking game as well, where everyone had to take a shot for every two hundred dollars they made. So, if someone gained 2,000 fictional dollars they had to take ten shots. The only reason Natasha wasn't playing was because she was running late, having been in a debrief with Hill, and the guys turned it into a dude bonding thing. That and they were getting impatient.

"Hey!" Clint slurred, waving his hands in a frantic gesture. He whacked poor Steve across the face, not even noticing as he yelled at Bruce, "You landed on New York Avenue, cough up the cash Bruce!"

Bruce glared, "You don't own New York Avenue, I do!"

"No I do!" Clint started to frantically shuffle through his cards, trying to find the proof he didn't actually have. In reality, Thor was the owner of that space.

"Actually guys, Thor-"

"SHUT UP STEVE!" Clint snapped, making the sober soldier back away slightly from the group. Poor Steve, the games banker before he can't possibly get drunk, caught in the middle. Natasha almost considered stepping in to break up the game and stop it from getting out of hand but she was actually a bit amused by this. She looked over at the strawberry blonde as she sipped her wine, glancing at Natasha silently.

"The Captain is right my friends, I Thor Odison rule the Avenue of New York."

"No!" Clint held up a card, but in his drunk state didn't realize it said Connecticut Avenue, "See? I owns it! So cough it up Bruce!"

"No friend Bruce, you must pay me!"

"I'm not paying either of you it's my space!"

"Should we stop this?" Pepper whispered to Natasha. For a brief moment the assassin pursed her lips in thought.

"Not yet."

"Well fine!" Clint turned, "Don't pay me. But I'm getting my money one way or anothers." Clint clumsily poured himself, another shot, spilling it all over the place and reached out, grabbing a handful of Tony's money. Without even counting it, he drunk the overflowing shot he had poured himself.

And thats when Tony joined the fight, tackling Clint for taking his money. He slurred profanities, profanities that Natasha was sure would be really harsh if they could only understand a word of it. But the billionaire was so drunk, that he was incomprehensible when he spoke.

Clint kneed Tony in the stomach and shoved him off of him, right into Thor. Thor leapt to his feet, bellowing in anger. Before Clint could do something stupid, something that could land him in a hospital bed, Natasha had wrapped her arms around him and restrained him. She had crossed the distance in a heartbeat, and despite being smaller than him, she had no problem restraining him.

"Game over," She glared as Pepper started to pull Tony away, no doubt to go put him to bed where he can't possibly hurt himself. Steve stood, ready to restrain Thor as best he could. But Thor merely turned and disappeared down the hall to go to his room, with Bruce clumsily trying to help Steve clean up the game.

"Come on Clint," Natasha turned him around and guided him towards his room.

"But the game isn't over with," Clint complained loudly, stumbling. Natasha softly groaned, wrapping his arm around his shoulders so he didn't fall. So she could help him walk.

"Well, if you keep playing then you're going to end up with either a hangover and a couple other injuries. That, or alcohol poisoning. And you're no good to me on missions if you're dead."

"You're probably right," Clint's head fell onto her shoulder, "And your no good to me if I'm am dead."

Natasha dragged him into the elevator and pressed the button. She propped him up as best she could against the wall, but his entire body sagged forward.

"Hey Natasha," He slurred, his eyes staring up at her but not quite seeing her, "Have I ever told you that you're really sexy when you speak Russian."

"Yes Clint, you've mentioned it many times before," Natasha sighed. She was used to him saying stuff like this, especially when he was drunk. Almost always when he was drunk.

"Talk to me in Russian," Clint blinked, rocking on his feet, "Let me hear you talk to me in Russian."

Natasha sighed, and dragged him out of the elevator the moment it opened. She looked at him,"Clint, you're drunk. You're going to bed."

"I'm not drunk," Clint ripped himself away from her and immediately fell on the ground, so drunk that he couldn't even stand. Natasha reached out to catch him before he fell, but he merely brought her down with him.

"Smooth Barton," Natasha turned to look at him, just in time to see the archer cracking up in a hysterical fit of laughter. She couldn't help but crack a grin at his contagious laughter and join in a bit.

All of the ememories they had together, every story they could flashback to, those stories meant nothing now. They weren't friends anymore, they weren't allies or partners, Natasha desecrated those memories by betraying S.H.I.E.L.D., the Avengers, Clint.

Now we got problems

And I don't think we can solve them

You made a really deep cut

And, baby, now we got bad blood

Hey

Natasha knew that she had hurt Clint, she wasn't an idiot. She knew she hurt him, the Avengers, everyone who ever trusted her as an agent. She hurt them more than just physically, she did more than physically injure them especially Clint. But a part of her, the good seed that Clint and the Avengers unknowingly planted in her craved their good influence. Craved their presence. Guilt clawed its way through her heart, clawed through her from the inside out.

When she entered S.H.I.E.L.D., she was always a double agent. She had always intended on betraying them, and being so trusting to a few hand picked individuals just made her cover all the more convincing. The KGB had never expected the Avengers initiative, and if it hadn't actually been used she probably would have betrayed them sooner. But the Avengers were formed, she was an Avenger. She gathered more information for the KGB. She's always intended on betraying them, but something in her broke when she did betray them. She actually liked being one of the good guys and she never really knew it until she revealed herself as the bad guy.

So she left, she left the KGB to be the hero she'd been pretending to be. She came looking for Clint, because she had honestly hoped he'd take her back. She thought that she could fix them. That she could be the hero he thought she was. All Natasha wanted was her archer back, even if he was out of the spy and super hero gig. She just wanted to be with him. To patch them back together.

And he was telling her to fuck off.

Natasha reached out and caught his shoulder, spinning him around to stare back at her, "Clint, I'm sorry. You can't really be walking away from me. Think of everything we've been through."

Band-aids don't fix bullet holes

You say sorry just for show

If you live like that, you live with ghosts (ghosts)

Band-aids don't fix bullet holes (hey)

You say sorry just for show (hey)

If you live like that, you live with ghosts (hey)

If you love like that blood runs cold

'Cause, baby, now we got bad blood

You know it used to be mad love (mad love)

So take a look what you've done

'Cause, baby, now we got bad blood

Hey

"Everything we've been through?" Clint echoed as a question, staring down at her with a glare. His grey eyes met her green orbs, "You think your little apology will make me forget about the pain you put us through? Bring us back to before you revealed yourself as the deceptive bitch you really are?"

"Clint," Natasha stared at him, "I promise I will never betray you again."

"I know you won't," He says, "Because you're dead to me."

Natasha stared at him silently, her green eyes widening at the heavy implication of his words. She was dead to him. She meant nothing to him anymore.

"Don't say things like that Barton," She whispered emptily, her hand falling away from his shoulder.

Clint stared down at her, getting angrier and angrier at her. She lies to him, she lies and betrays not only him but the Avengers and suddenly comes back looking for some sort of forgiveness. What Natasha was trying to do was exactly like putting a band-aid over a bullet hole. You could cover the unsightly wound but the damage behind it is still there, and not even the bandaid can change that. They couldn't go back to before her betrayal, because the pain she caused would always still be there.

"Why?" He asked, "You're trying to live in the past Natalia. You're living with ghosts, people who don't exist anymore."

"I'm done being who I am now. I'm done being the villain the KGB has not only made me out to be, but someone who will fight you again. I don't want to fight you all. I made a mistake ok? I want to be the hero I used to be."

"You were never a hero," Clint glared, "You were a spy. A spy for the wrong people. You had ten years to come clean. Ten years to decide that you liked being the hero for once and give yourself up to S.H.I.E.L.D., to Fury. But you didn't. You are not the woman I thought I loved."

Natasha paused for a moment, holding her breath, "You loved me?"

"No, I loved Natasha Romanov. I loved a cover. You're Natalia Romanova. I never loved you. I was sent to kill you. And I regret not following orders."

Without another word, the archer turned and made his way out of the alley, melting into the New York crowds and disappearing.

Now we got problems

And I don't think we can solve them (think we can solve them)

You made a really deep cut

And, baby, now we got bad blood

(Hey)

Natasha stood there, staring at where Clint Barton once stood, staring at his ghost as he walked right out of her life and disappeared, right into the crowd of New York. She stared at the ghost of the man who once loved her, the man who would risked everything to give she a redemption. To make her a hero.

She could have prevented this. She could have come clean and told S.H.I.E.L.D. about the KGB, about her true intentions. Maybe they would have respected her for coming clean and telling the truth, or maybe they'd have thrown her in prison and melt the key. Or maybe they would have shot her dead right then and there. But they all sounded so much better than the consequences she was facing now. If only she hadn't lead the KGB in an attack against S.H.I.E.L.D., if only she hadn't help destroy S.H.I.E.L.D., if only she hadn't betrayed the only people who truly cared about her.

If only she had come clean, then Clint wouldn't hate her. Then she would still have him. Him and Steve and Tony and Bruce and Thor. But she didn't, and now she'd damaged all of her relationships to the point of no return.

She had no one. Clint was right, she wasn't Natasha Romanov. Natasha Romanov didn't exist. She was Natalia Romanova. A traitor to her friends and enemies.

'Cause, baby, now we got bad blood

You know it used to be mad love

So take a look what you've done (look what you've done)

'Cause, baby, now we got bad blood

Hey

Clint Barton walked all the way to Avenger's Tower, never looking back. Well, every now and then he would make sure he wasn't being followed, but he never looked back in the sense that he was regretting his decision. It wasn't that he didn't love Natasha Romanov anymore, it was that he had accepted the heartbreaking truth. He accepted that Natasha Romanov never actually existed. He had accepted that the woman he loved was as real as Natalie Rushman. No, the woman he was with in that alley was not the love of his life, just another spy who should have died at the end of his arrow.

Now we got problems

And I don't think we can solve them

You made a really deep cut

And, baby, now we got bad blood

Hey

And he knew that no matter how hard she tried to win him back. No matter how hard she tried to prove herself a hero to him. No matter how sorry she is or how many KGB bases she destroys, he will never forgive her and take her back. He was a fool to trust her the first time. He will never make that mistake again.

End of the chapter. :D You have no idea how long I'd been dying to write this. I'm sorry if it's long. I'm sorry if it hurts your feels. I'm sorry. It hurts me too. I'm a big Clint/Tasha shipper.

Ok, well, I gotta really thank Dizilla because I sent her a small segment of the story and she really liked it.

And independentalto. I love her story All the Reason's Why. It's just a series of beautiful one shots and she does an arrangement of ships. She's a very loyal Romanogers fan who has actually gotten to me ship that ship. She does so much more than romanogers, she has Stucky, Natasha/Skye, Mockingnerd, Hunter/Bobbi (I forgot the ship name), she does so much. She's open me up to different ships that I'd honestly didn't look at. Perhaps I'll do a series of one shots too, with music. And if I do, I gotta honestly thank her because she's so good at it. And she gave me the idea for the title.
