Sorry I haven't updated in a while! But good news: today I took my last final exam and it is officially the first day of my summer, so I'll actually have some time to write;) Well I hope you enjoy this chapter, again I am sorry that it took so long, and please review!

They made their way through the arid terrain silently. Each step was taken carefully.

"So Agent Barton, how did it feel to cuddle up with a master assassin last night?" Tony whispered with a smirk on his face. Steve pretended like he didn't hear anything and so did Natasha for the most part—she simply raised an eyebrow.

Clint snapped his head around and stared at Tony in bewilderment. "What? Didn't think I noticed?" Tony continued to smirk. Clint turned back around and acted as if Tony never asked and tried to read the expression on Natasha's face.

Hours later, the Avengers were only a few hundred yards from the warehouse. It was very dark and very quiet. Tony quickly, and as silently as he could, gathered the reluctant marksman in his arms, and set off for the roof. Once there, Natasha and Steve heard the 'okay' in their ear buds.

"Get behind me," Natasha ordered, "and whatever you do, do not bring attention to us."

"You got it, Black Widow." Steve replied.

In less than a minute, they were at one of the doors, but it was locked. "I got it. I can break the chain with my shield." Rogers stated as he lifted the metal above his head.

"No!" Natasha hissed at the ignorant soldier. "Too loud…" she said less bitterly.

Steve watched carefully as she removed a small capsule from her belt and unscrewed the top. "All clear?" she spoke into her microphone.

"Yeah," Clint answered from the other end. Then she poured a clear liquid onto the metal chain and it disintegrated before their eyes.

"What was that?" Rogers whispered.

"A concentrated poison… of sorts. I used it a lot when I was a spy for the KGB," she stated, then turned to look at the Captain, "except I didn't use it on locks."

She could see the man swallow hard and smiled reassuringly. "Don't worry Cap, I haven't used it like that for years."

"Can we get a move on it down there? I would like to get home sometime soon," Tony, obviously bored, requested in their ears.

Without a reply, Natasha slowly slid open the door and slipped inside.

There was a low buzz of voices inside the warehouse, and dim lighting made it perfect for her to move around unnoticed.

"Shit," Natasha heard Steve say from under his breath. She looked up to see the same horror as he did. There were bombs everywhere. They lined the walls hundreds of feet up and in front of them, on ladders, were men in lab coats with machine guns. It may have been nighttime outside, but the terrorists were still very much alert and at work.

"I can get up there," Natasha pointed to a loft with a window looking out onto the work deck. It was obviously were the leader of the organization was. "But I can't be worried about you behind me. Stay here and watch my back. If you see anything coming or anything suspicious, let me know through the earpiece," she ordered as she tapped her own. "And if we are compromised, get out. Do not look back for me. I will finish the mission and be right behind you. Understand?"

Steve stared worriedly at the Black Widow. Her words frightened him and he didn't want to agree. "No man," he cleared his throat, "or woman, left behind."

"Don't be a hero Cap, I have been doing this for a very long time and I am no damsel in distress. I don't fail." Her face was stern. Rogers couldn't argue with her, he didn't even know how.

Natasha turned and agilely leaped onto a metal container. She landed on the balls of her feat and silently took flight again, this time grabbing onto a pipe with both of her hands and propelling herself onto the rafters. Steve watched in awe as the Black Widow calmly bounded from rafter to rafter, until she was almost above the office. She glanced once back at Captain America and winked before diving up and over the wall and into the office.

Steve waited for a scream, for a noise of some sorts, but nothing came. He searched the rest of the warehouse for something out of place, but no one seemed to recognize a thing. He couldn't see the tinted window, and he hoped that no one else could either.

"I got him," her voice buzzed through the speaker of the other three earpieces. The other Avengers could also hear groaning, but they tried to ignore that.

"Was anyone else up there?" Clint inquired.

"Yeah, a few, but they won't talk," she answered nonchalantly. "Let's get out of here."

Steve shifted in relief and almost simultaneously, a siren went off and there was a flash of lights and yells from every crevice of the warehouse.

"Seems like someone spotted your striped friend, Miss," a man with a heavy accent declared with a smile in his voice. They guessed it was the man Natasha was holding, the leader.

"Steve, get out of here!" Natasha yelled into her microphone as men with machine guns ran towards him and up the stairs to the office.

"What about you? They're coming up!" Steven yelled back.

"GO! I can handle this!" she replied out of breath. But Steve didn't believe her. There was no way out of that office except for the door the armed men were about to crash through and over the wall, but there was no way that Natasha could lift a man and herself over it.

The metal released from his hand and Captain America's shield spun through the air, taking out nearly ten men at once. He caught it as he bounded up the same metal container Black Widow recently used. He wasn't as graceful or agile as she was, but he could leap farther because of the super serum. He got to the rafters, making his way to where Natasha was, and throwing his shield to take out terrorists every few steps of the way.

Some of the men had broken down the door and were taking fire into the office. As Steve jumped over the wall and into the room, he hurled his shield once more, taking out four of the men. There were dead and injured bodies everywhere, thankfully none of them Natasha's.

"What are you doing here? I told you to get out!" Natasha chastised from the other side of the office as she flipped through the air, snapping necks and causing the terrorists to shoot their own allies.

"I told you, I won't leave you behind," Steve answered as he released his shield once more and punched some guy through the window. "Where is the leader?"

"He got shot. I guess we won't be asking him any questions," Natasha exasperated as she took down man after man.

Just then, another—louder—sound erupted from the other side of the warehouse. Someone was setting off bombs.

Okay so… I don't know how this became an action fanfic but… I'm sorry? Anyway, please review and as always be brutal!
