"Have you heard from Natasha?" Tony demanded, walking toward Steve, Clint, and Bruce, who were sitting around in the living room of the Avengers tower.

They all looked at him with confused expressions on their faces.

"She isn't with you?" Clint asked, worry filling his voice.

Tony shook his head, breathing out. His chest hurt and he felt like he was going to be sick. He had called her earlier that morning to talk about if they were going to do anything that day and then make arrangements. She normally picked up right away, but when she didn't, Tony knew something was up. He had tried calling about six more times after that but to no avail. That's when he decided to come to the Avengers tower, hoping maybe she was here or one of the other guys saw her.

No such luck.

"I dropped her off at her house last night," he informed them, bringing up a few screens on the monitors hanging in the room. "And now she's gone. I tried calling, but she didn't answer. And she always answers."

He looked through several files, trying to see if she had hit one of the panic buttons in her home. But she hadn't. He briefly wondered if that meant she was okay, but quickly pushed the thought aside. If she was okay, he would have heard back from her by now. He sighed, aimlessly scanning through files, hoping that something would come up as to where she might be.

That's when Tony remembered the audio recorder he had secretly set up in her apartment. He had done it back at the beginning of their mission, wanting to be sure that he had some way to know if anything bad had happened to her in case someone tried to harm her in any way. Tony knew that if someone was going to try to harm him, it would be through his biggest weakness – his girlfriend, who was being played by Natasha at the moment. It only took a minute for him to find the files from the audio recorder.

"Jarvis, scan through last nights' recordings and see if anything abnormal comes up," Tony instructed the AI.

He sat down and strummed his fingers against the desk, staring up at the monitor impatiently. She had to be safe, this was Natasha for crying out loud. Maybe he had said something yesterday to upset her. He carefully thought through their conversations in his head and failed to come up with anything that would push her away so much.

"Sir, I found something abnormal at the time 11:48 pm. Would you like me to play it for you?" Jarvis reported.

Tony sat up in his seat, extremely focused in on what the AI had just told him. He barely noticed Steve, Clint, and Bruce walking over to stand behind him to listen to the audio themselves. It seemed that they were all hoping that Natasha was perfectly safe, that whatever Jarvis had deemed to be abnormal was actually nothing.

"Yeah, play it."

The audio was silent at first, none of the men able to detect any noise. Then a faint creak was heard, and a sudden struggle. There was a groan and a quiet thud, as if someone had fallen. A quiet click was heard, then finally, someone speaking.

"Get off him, Agent Romanoff."

Tony swore that he could feel his heart jump in his throat as soon as he had heard the words. She was ambushed last night. From the sounds of the recording, there seemed to be only two people who broke into her apartment. She should have easily been able to take them out.

He was pulled back into listening to the audio once again when there was an apparent struggle. There was a thud again and a man – possibly the same one who had just spoke – groaning in pain.

"Who are you?"

That was Natasha that time. At this point, she was still fighting. Good.

"I'm afraid we can't answer that."

"But you can. So tell me, who are you. And don't think I won't shoot, because I will."

Tony couldn't help but smirk a little bit. He knew she would get control of everything. She had the gun, and he knew very well that she would shoot if she had to.

His heart sank and the sudden realization that if she had indeed gotten control of the situation, and stayed in control, that he would know where she was.

The man chuckled. "Go ahead. Do it, then."

A tick could be heard, and then what sounded like a fog machine. Tony's eyebrows furrowed together, fearing what these sounds might mean.

"Let's take her back to base. We'll get answers out of her there."

Tony straightened up in his seat, staring intently at the screen, as if he were trying to see into the previous night so he would be able to get a description of the man who was now kidnapping Natasha. To be able to pull a stunt like this off, they had to be trained.

"Jarvis. Pause it and do a voice recognition on the last person who spoke."

"Will do, sir. Voice recognition in progress now."

Someone had cleared their throat behind him. He quickly spun his chair around, seeing Steve, Bruce, Clint, and now, Fury.

"I see that Agent Romanoff is not here with us yet," he stated, looking around at the four Avengers, then settled his eyes questionably on Tony. "Do you know why that is?"

"It appears that the Black Widow has been trapped in a jar," Tony said between teeth.

How he was able to be sarcastic in this situation, he would never know. Because right now, he was worried sick. Worried that they would not be able to identify the man who had talked in the recordings, worried that because of this, they wouldn't be able to find Natasha, and that she would –

No. He would not think like that. They would find the men who did this to her and they would be punished. That is, if Tony didn't his hands on them first.

Fury's expression faltered just slightly. "Do anything you can to find her. Finding her will be our top priority right now."

Tony, Steve, Clint, and Bruce all nodded to Fury. Fury nodded back, then turned around and walked away.

"I have been able to identify the man in the audio recordings, sir."

Tony turned his chair around. "Spill the beans then."

"It appears to be a man by the name of Victor Remmings."
