Kaylee - Age 10

"You're going to be a good little omega," a nurse cooed to the young girl. She hasn't even hit puberty yet and almost everyone keeps calling her an assumed presentation. She didn't lash out at the assumptions but knew that, if it's true, she won't be important like she hoped she would.

This feeling of importance started only a year or two ago. Growing up in an orphan house wasn't ideal for any presentation - beta, omega, or alpha. But luckily for her, all her 'orphaned siblings' turned out beta or omega. She knew the feeling of wanting acceptance - maybe she was an omega.

"Ma'am?" she started before the nurse lashed at her for speaking out of turn. Maybe a fear scent mingled into the air as a guard knocked on the door and asked if she was ok. Looking up to the nurse, who nodded, she relaxed. "I'm fine," she called out politely and heard the footsteps move away from the door just a bit.

The first day at the boot camp was horrible. She wasn't really built for anything as she spent her previous days inside doing household duties for the 'alpha' in charge of the house. With each physical test, she found herself half way through, on the brink of begging someone to make it stop but she always, successfully ended with the encouragement of her siblings. For kids, Hydra was calm with the output but merciless compared with the input - until one day.

As the weeks raged on, Kaylee was forced to stay behind in boot camp to gain more muscle as the rest of her orphaned friends moved on. As more recruits for hydra came in and left, she began being depressed about her family and angry at hydra for not letting her pass - until the Winter Soldier came to validate the tests.

She tried her best - like she always does - but something told her not to beg in front of the man with a mask and the metal arm. The other recruits started teasing Kay about her scent as she sweated through the tests but she knew something was different with the way they were reacting to her as the majority were older - much older.

"What's wrong little orphan," one of the older boys sneered at her.

"Shut up, Mason!" Kaylee hissed at him.

Finishing the last test and crouching down to breath some and relax her aching muscles, everyone stood at attention as the Winter Soldier started walking towards them with two others. She didn't even notice until his shadow covered her.

"Stand," he growled and she obeyed, going to join the others on one side of the line. As he looked around, he kept darting his eyes to the other two he walked with.

He came up to each person to stared them down. It was almost frightening but she's realized by now, this is HYDRA.

It was her turn. As he loomed over her, Kaylee hesitantly looked up at him. He looked better without the mask and it calmed her down.

"Name?" He asked.

"Kaylee, sir," she told him. "I don't have a last name."

He gave a quick nod and walked back to the two men. Their conversation was quiet and quick.

"Kaylee and Mason," one of the other men called. "Step out and come with us."

Present Day

"Kay?" A voice called to her. She was staring at the wall again at dinner the next day. "Kay!" The voice called - it was the Captain. "Kaylee!"

"What?" Her snapped over to him and glared. "What the hell do you want?" She hissed, trying to look mean but was embarrassed by the small daydream.

Steve looked taken back. "You haven't touched your food," he pointed out and looked around the table to the rest of the team. "You haven't eaten all day."

Kaylee mentally hissed at herself. Today was just one of her moods in defiance of her presentation. "Just," she started calmly before immediately standing, slamming her hands on the table getting angry. "Fuck off!" She yelled and stormed to the stairs to go to her small apartment, two floors below.

Just thinking about boot camp brought back the pain of advanced training and missions with the Soldier. She hated him with every fiber of her being. She hated HYDRA for forcing her into boot camp but one thing was for sure, she felt that she was important for HYDRA.

She scavenged around for her suppressants that HYDRA gave to her an abundance of every year. She only gave Shield three so they could recreate the suppressants specially made for her but thankfully she has a two years worth of the pills.

She held the bag close like it was her life - as it was. If shield doesn't recreate the pills for her, she can't take the regular pills to stop her heats.

"I hate being an omega," she whispered into the small room as tears escaped her eyes. "Screw HYDRA. Screw Shield," she sobbed, hugging her 'life line' tightly before the last thing she knew was hideous sleep as nightmares from the old days haunted her.

Steve watched her go sadly and looked around at the rest of the betas. "I wish I knew what happened to her," he mumbled before taking another bite from the steak on his plate. He knew what she was feeling, as much as he could tell from her actions and reactions.

"There's nothing in the database of Hydra that says she was Hydra," Natasha told him, taking a bite of her food too. "She'll tell us when she's ready."

"What if we -" Tony started before getting a glare from Steve.

"You can't do that, Tony," Bruce said, finally speaking up on the matter. "She's an omega," he looked around the room. "And shield's trying to recreate her pills but - we need more of them."

"You keep taking them she'll be pissy!" Nat hissed at the other beta. "If shield can't make them then - who knows what will happen to her."

Clint, the only one who hasn't spoken about it or to the young girl, shook his head. If Hydra could make the suppressants for her, why couldn't Shield? He spoke his mind, finally breaking his silence for the matter. "There's something they gave her that could help with the recreation. There's a reason Hydra made special ones for her."

The rest of the team sat in silence as they finished eating. Steve and Natasha were just getting done with the dishes when the alarm went off. They both groaned as they set a bee line for their rooms, making sure everyone was up.

Going to where the matter was needed, Kaylee found herself in an alpha type situation with Natasha. With an asset being retrieved, it was for better or for worse that Steve was not part of it.

"It's him," Steve called while a few alphas dragged him off the plane. "You're getting Bucky, aren't you!" he stared at Fury and Natasha helplessly. "I need to be there! Bucky -"

"Will be fine," Fury stated calmly to the beta as he was walking out. He turned to the others and pointed out Kaylee and Nat. "You two are in the lead. Natasha knows him from back then and you know how hydra has been trained."

Kaylee glared at him but nodded. "Yes sir," she said. "The asset?"

"He's not an asset, more or less," Sam piped up from the back, looking through a small file. "He is Steve's best friend from childhood," He looked up at the team and through the file on the table, making a picture fall out. "And an assassin."

Kay stared at the picture and shook her head - the entire mission coming back. "No," she whispered and stepped back till she touched the metal wall of the plane. "No!" she screamed at them. "I can't! He'll hurt me! He's not a fucking friend, he's a murder!"

Nat turned around to the now shaking, fear scented omega. "Kaylee, he's not the Winter Soldier," she tried to tell her calmly as the alpha and other beta stared at her out of sadness - they found one little thing about her.

"Do you have any idea what he can do?" she screamed at the beta and tears started falling from her eyes. "He's reckless, vicious and cruel! He's just like every fucking alpha out there!"

Fury seemed to swallow hard and looked down at the omega. "You can stay on a rooftop and watch. You're still taking point with Natasha on this one. We need to trust you," he said, almost growling out the last part. "Understood?"

Kaylee glared at him. "He doesn't come near me. He won't know I'm here," she said eyeing all of them. The visions of his assassins coming to her rapidly. "He can't know," she whispered to herself as she hugged her legs and tried to relax.
