Summary: When a mission goes wrong Natasha must be comforted by Steve but he is hiding a terrible secret. Can he continue lying to her about what really happened to the man she loves?

Please review and let me know what you think!

Positive.

As Natasha stared down at the little stick one word was replaying itself over and over in her mind.

Positive.

How could she be pregnant? How? They had been careful. She had fearlessly faced many battles in her life but now, faced with the biggest one of all, she was terrified. She was a master assassin. There was no way she could be a mum too.

Clint.

Even as the name came to mind she felt herself relax. Clint would know what to do. Of course. He would tell her exactly what they needed to do.

On the other side of the bathroom door Stark was banging and shouting but Natasha paid no attention. As gently as any mother could she cupped her flat stomach and imagined she could feel the baby's tiny heartbeat. Her baby.

Natasha walked into the living room of the Avenger's Tower to find Nick Fury waiting.

"Black Widow. Gather the rest of the team. I have urgent news." He commanded. Natasha turned without another word. As she searched for her team mates she couldn't shake Fury's worried face out of her mind. The old director had faced many battles and he never showed fear. Now he was worried but not because of the mission. He wasn't sure why he was worried. Maybe it was just what would follow. Maybe he was getting too old for this job.

She found Steve in his room on his laptop.

"Fury wants us all down stairs now." Natasha told him and he nodded.

She found the rest of the team except one and told them all to go down to Fury.

She found Clint in their room, staring out of the window. As quietly as she could she passed the unmade bed and stepped easily over all their scattered clothes.

She slipped her arms smoothly around his waist, her chin fitting onto his shoulder.

"Looks like dinner tonight is off. Fury's downstairs." She told him. He turned to face her, his scar lined face looking lost. He had been like this for the last few days but she hadn't worried about it until now. His eyes looked so lost and confused she almost didn't recognise the deadly assassin she loved.

"Oh right. Let's go so." He replied his voice distant and it really worried her. He slipped his hand into hers and took a step towards the door.

"What's wrong?" she asked, pulling him back.

"What? Nothing. It's nothing. Don't worry about it." He told her. She raised an eyebrow at him. He sighed knowing his girlfriend was not one to let things rest. "Honestly it can wait." He promised her, smiling. He gave her a quick kiss.

"Wait. C'mon. They're not screaming for us to come down yet so tell me." she begged him. Natasha never begged with anyone else. She could find out information from others with less vulnerable methods. But Clint knew her inside out and knew her every trick. Begging was the only way with him. she hated how weak he made her feel but at the same time she loved how safe she felt with him around.

He gestured to the bed and they sat. He paused for a moment, his lips pursed, hands clenched. Now he really had her worried.

"Do you ever wonder why we do this?" he asked his voice guarded. They shared everything. Why was he guarded now?

"Do what?" Natasha's heartbeat quickened and her palms suddenly felt sweaty. Do what? Love each other? Be together? Surely he didn't mean…

"Fight. Kill. What's the point?" he asked, his eyes searching her face for any reaction.

"What's brought this on?" She asked, trying to keep her voice even.

"I don't know. It's just with mission after mission… it just never ends. And it never will. I don't know. I just think maybe it's time to stop." Natasha thought about what he was saying, mulling it over. Before she could reply there was a knock at the door.

"Fury wants you downstairs now." Steve told them. Clint nodded and stood up. He held his hand out for Natasha and she took it.

"Two hours ago I received word from Thor that Loki has escaped Asgard. One hour ago I was informed of a hostage situation in a warehouse in London. Loki is behind it and we need you all to investigate." The room was silent after Fury's statement.

"Let's go." Tony replied. Steve and Bruce stood, nodding. Natasha watched as Clint stood too, a look of determination on his face. She knew he wanted to kill Loki for the mind control but she was less eager to face Loki. His words still rang in her ears but now, with a heavy heart, she joined her team.

Natasha drew her guns from their holsters, feeling comforted with their weight in her hands. She stood, crouched behind a stack of wooden boxes in the corner of a warehouse. From her perch she could see Loki walking between a circle of about one hundred people, all of them on their knees, terror etched on their faces. Glancing up she could see Clint hunkered down in the rafters his bow already raised. Through one of the roof windows she could see Tony in his Iron Man suit, flying through the dark night. Steve stood behind her, his breath warm on her neck. Bruce was nowhere to be seen.

"You know I expected your heroes to be here by now…" Loki commented. Natasha could see Clint glance down to Steve for the signal but Steve shook his head.

"I suppose there's no point keeping you all here anymore so…" With ease Loki strode towards the door.

Something's wrong… thought Natasha. He was giving up too easily.

Loki reached the doorway.

"No point keeping you alive either." He told them and shot Natasha a smirk. He knew. Loki threw a metal ball into the air confusing everyone. The instant the ball hit the ground it exploded, sending everyone flying through the air and causing the whole building to explode.

And even as Steve threw himself on top of her, his shield protecting them both, Natasha could have sworn she heard Loki laughing.

Okay so this is the first in a multi chap story but if I don't get response I won't continue! Thanks for reading and please review!
