Chapter 1

"I vote we never do anything like that again." Clint said while holding an ice pack to his head.

"It wasn't that bad," Steve replied, getting out of the quinjet. Steve, Clint, and Natasha had just gotten back from stopping some terrorist group who were trying to bomb the White House. While it was a fairly easy mission, Clint had gotten a minor concussion, and Natasha was walking with a slight limp.

"Easy for you to say, Mr. Superhero Serum, you don't have a scratch on ya."

"Well I guess he's just better at dodging punches than you." Natasha said with a slight chuckle.

Clint huffed indignantly as they headed in to the tower and went to try and get the smell of ash and blood off of them.

A few hours later they were called in to get the remaining people of the terrorist cell and bring them in for questioning.

"Why can't Fury just send some of his other monkeys in, I'm sure they'd be able to get this done just as easily." Clint complained for the millionth time as they were walking towards the quinjet once again.

"I'm sure Fury has his reasons." Natasha replied, obviously annoyed. She had been listening to him complain for the last three hours how his head hurt and it honestly took her all her willpower to not kick him where the sun don't shine.

"The sooner we get this done the sooner we can go home. How far out are we?" Steve asked while looking at the blueprints of the abandoned office building the terrorist were believed to be hiding in.

"Ten minutes," Natasha replied.

Steve turned to Clint, "Hawkeye, you're going to sweep the perimeter of the building and check for traps, then drop down through the skylight and hit as many as you can with tranquilizers." Steve then turned to Natasha, "Once he gives us the okay, you're going to go in the back entrance and I'll go in the front. Remember we need these guys alive, so don't kill them if you don't have to."

"ETA thirty seconds."

"Ok guys lets go."

"Does anyone else think this was too easy?" Natasha asked suspiciously.

"Maybe we're just really that good." Clint replied.

"Usually if it's easy, that means something's wrong."

"Let's do a final sweep of the rooms. You guys take this level, I'll take the second floor." Steve said while walking towards the steps.

Each room was about the size of an office, most without windows, and had almost nothing in them. The place was probably just a temporary hiding place till they got to home base. Steve only had a few rooms left to go. 'Great, almost done' He thought. He honestly wanted to just go home. Missions like this always made him frustrated. All terrorists want is to spread fear and that just pissed him off. Pointless acts of violence.

He was so lost in his thoughts he almost didn't hear the faint cry. He looked around, thinking he must have imagined it, but then he heard it again. It was just barely there. He ran through all the rooms looking for the source of the sound, but couldn't find anything. He went back to the room he had heard the cry and looked around. 'This room is smaller than the others' He noticed. He pressed his ear to the south side of the room and listened carefully. 'It's definitely coming from there.' He backed up and braced himself. Three, two, one. He hit his shield against the wall and a hole just big enough to see through appeared. The crying got louder. He looked in and saw a small baby screaming it's lungs out and frantically waving its arms, clearly scared.

Steve hit his shield against the wall a few more times. He went through the hole and walked up to the crib. The cries quieted as soon as he was next to the crib. What he saw nearly broke his heart. In the crib was a small, shivering, baby girl with blue eyes. She couldn't have weighed more than ten pounds. He put his shield on his back and carefully went to pick her up. Wow she's small.

Turned on his comm. "Guys, we have a situation."

"Cap? What's wrong?" Clint asked worried.

"I found a baby."

"You found a what?" Clint asked.

"A baby, I found a baby girl." Steve looked down at the baby in disbelief and saw she had fallen asleep and slowed to a walk to not wake her.

"Are you sure?"

"Of course I'm sure. What do you think I don't know what a baby is?" Steve snapped at Clint as he was walking towards the stairs.

"Cap, bring her down. The quinjet's here." Natasha said.

When they finally saw Steve coming down the stairs, they saw that he was, in fact, carrying a baby.

"I thought he was joking." Clint stated in disbelief as he stared at the bundle Steve was holding wide-eyed. Of all the things to find in a terrorists' hideout, who would've thought it would be a baby?

"Do you really think he would joke about something like this?" Natasha replied with a mirrored expression. 'What would terrorists want with a baby?'

"Where did you find her?" Clint was still in shock it seemed.

"She was in a hidden room. I heard her crying through the walls."

"What could they possibly want with her?" Natasha said with a slight anger in her usually emotionless face. Clint knew the anger came from how she was raised, but Steve didn't.

The baby was taken from Steve's arms when they got on the jet to be examined. Hopefully they could find out why these terrorists wanted her. The shift woke her up but thankfully, she didn't make a sound. Steve watched warily as the doctor examined her.

"Find anything?" Clint asked hopeful to get a reason why they would want this baby.

"I cannot find a single thing wrong with her," the doctor sighed. "She has no strange injuries, injection sites, nothing. Of course I won't know for sure till we get to headquarters and can do more thorough testing. But, otherwise, she seems perfectly healthy. She didn't even cry when we took blood."

"Then what could they possibly want from her?" Natasha asked with a dangerous glint in her eye. Clint could tell this was getting to her.

"I honestly have no idea. Like I said, maybe we'll know more when we do a more thorough examination."

"How old is she?" Steve quietly asked.

"My best guess is around one month. I'm not really sure."

"So we got nothin'? Can't wait till Fury hears about this." Clint mumbled.

"Just did. So let me get this straight, you found a one month old hidden in a terrorist hideout?" Fury stated in his usual no bullshit manner as he walked into the room.

"Yup."

"And there's nothing unusual in about her? At all?"

"Besides finding her in a terrorist hideout? No."

Fury was rubbing his temples trying to fight his oncoming headache. Of all the things. "I'll have her taken care of. You're dismissed." A moment after he said that, Agent Hill ran in.

"Sir, there's been a break in. Three intruders. Alien. They're heading here."

"What are they after?"

"We don't know. My best guess is that little girl." She said, nodding in the girl's direction.

The three intruders burst into the room. All had a light purple skin. Great, now aliens are after her. What's so special about her? The aliens approached her and she stared straight at them. She was watching them carefully. Has she already gotten bigger? He watched them and tried to listen to what they were saying, but they were speaking a completely different language. They started advancing towards her. Now or never. Steve jumped up and threw his shield at one, while hit the other one. Steve caught his shield and while Natasha proceeded to fight the remaining one. The fight didn't last long. The aliens weren't expecting a fight.

He looked over to her. Her eyes were fixed on him. It's almost like she's studying me. He shook his head. That's not possible. She's only one month old.

"You can't just ask us to take a baby. What do you think we are? Babysitters?" Clint yelled at Fury.

"She needs protection until we find out why everyone is so interested in her." Fury yelled right back.

"Fury has a point, Clint." Natasha calmly said, putting a soothing hand on his arm.

"So you're siding with him now?"

"She needs to be protected and the safest place for her is Stark Tower?"

Clint was about to yell back, but he knew he wouldn't win any fight against Fury, especially if Nat's on his side. "I am not changing any diapers." He said and left the room. Natasha rolled her eyes and sighed. If only it would be that easy to convince Stark.
