Two days later, you and Tony had installed new security measures on the 'Team Floors' - the training rooms, the pool, conference rooms, the lab, the MedBay, the bedrooms, kitchen and common rooms. You were all confined to the same three floors, not allowed to access anywhere else until the mission was over. All of you had to wear these thin silver bracelets that held a nanotracker inside, reporting each move they made to an offline computer in the lab that Tony monitored. You felt a little bad that they were being imprisoned because of you, but then you remembered that meeting them, meeting Bucky, was the most likely reason for Hydra finding you. So really, they deserved it.

Tony had installed the same security measures on the other floors himself, seeing as you weren't allowed out, and before you knew it, your days were filled with the sound of irregular beeps and hums of handprint scanners and moving cameras, as the team went about their days. With the new security in place, you were allowed outside of the lab, across the three team floors, but Bucky was still literally glued to you.

Before Hydra ambushed the building, you might have enjoyed it. You might have used it to your advantage. But your little game with him had been long forgotten. You hadn't said a word to him since the basement, and you didn't plan on saying anything to him anytime soon.

Nat dragged you to the gym a few days later, as in you. Bucky was following the two of you at a reasonable distance (for him), and you just huffed your way through the halls as the assassin kept a death grip on your wrist.

When you got to the gym, you purposefully averted your gaze from the boxing ring. And the punching bag. You were grateful when Nat took you over to the floor mats, by the mirrors, gesturing for you to step on them first. She stood opposite you, Bucky leaning against the side of the boxing ring, watching you intently. You saw his eyes flicker to it, then back to you, and you weren't sure if you saw his eyes darken.

It might have just been the lighting.

You rolled your shoulders, putting your attention back on Nat, and began the mind-numbing and completely useless training session.

She started you off with punches. Righting your stances. Showing you the better jab methods. She moved onto legs, kicks, sweeps, agility. Then defence, blocks, reading your opponent, quick moves to get you out of the way.

Your brain started getting into it, the methodical instructions from her helpfully pushing out all your anger, confusion, frustration. Your body was moving robotically to her words, punching when she said punch, kicking when she said kick, bending when she said duck.

You were doing pretty well keeping up with her, but you also felt like she was holding back a lot. She was a super assassin after all, and fighting close combat was her strong suit.

You were taking a breathing break when you heard a voice behind you.

"Hey you're doing pretty good!" You turned to see Sam walking up to you both. "Maybe we should move you onto some take downs next?" He added with a smile. You almost wanted to smile back.

But before you can respond, Bucky appeared in front of him, his hand on Sam's chest, pushing him back, stopping him from approaching you.

You couldn't hear what they were saying to each other next, you could only see Bucky's back, his shoulders tensed and rigid. Then Sam was walking away. Bucky walked back to the side of the boxing ring, resuming his stance, and resuming his watch over you.

"He's acting like I'll disappear into thin air if he takes his eyes off me." You scoffed as you turned back to Nat.

"He's protective." She replied, a softness to her voice that you didn't really care for.

"It's not being protective. It's being paranoid. Not wanting anyone near me, not leaving me alone. It's fucking annoying."

She tilted her head, then looked over at Bucky, whose eyes were still trained on you. She turned back to you, stepping closer and starting to unwrap the cloth from her hands.

"It's well intentioned. He's trying to keep you safe. And he might be paranoid, he still holds a lot of that from his Hydra days."

You stiffened at Nat's mention of the organisation. She noticed your demeanour change instantly.

"Well, that's his own fault." You spat. Nat frowned at you.

"What do you mean?"

"He worked for them for all those years. If he still feels shitty then he should have quit earlier." You went to walk out, but as you passed Nat, she grabbed your arm, making you look round at her.

"He didn't choose that life." She whispered.

"Of course he did, they all did. Hydra sucks them in with false promises, but once you see the truth of what they do, everyone has the choice to stay or to leave."

"No, he didn't." She shook her head. "I thought you read our files? His file?"

"I have."

"Not enough then." She looked round to see him watching the pair, his eyebrows pinched together as he frowned at you. She pulled you a little closer to her, aware that his hearing was better than most. "Bucky was forced into it all."

"I know, they make you think you're doing the right thing, but you're still -"

"No, he was actually forced. They brainwashed him. Tortured him. Electrocuted him. Implanted a mode into his brain they could trigger whenever they wanted, and he wouldn't remember anything that he did. They froze him, brought him back out, triggered him into doing their bidding, wiped his memory then did it all again. It wasn't the same as the others."

You stayed silent.

You didn't know this bit. Whenever you read his file, you skimmed. You hated half-assing anything, but his relation to Hydra always meant that you didn't want to give him the time of day. You knew he was doing their bidding, but you figured it was the same as the rest of them, being conditioned into believing it was right. Not being brainwashed. That was different. That was completely different.

Nat could tell that she got you thinking. She let go of you, and raised her eyebrows at you as if to stay 'your welcome', then she walked away from you.

She was quickly replaced with Bucky. You looked up at him. You ran your eyes over his face with a new perspective.

"You okay?" He asked, his voice a little croaky and bland. It didn't match his eyes, which seemed soft, worried. You didn't respond. "Back to the lab." He muttered, and you nodded, following him out of the gym, your mind moving a million miles an hour.

Steve and Sam were leaning against the opposite wall, watching Bucky lead you out. Sam was the first to comment.

"You ever feel like Tony isn't telling us the whole story?" He muttered to Steve, who breathed in deeply beside him before tugging at the cloth on his hands.

"What do you mean?" Steve asked, but he already knew what Sam was about to say.

"I mean, this kid, Amy, whatever her name is. We didn't know she existed until what, 6 weeks ago? Suddenly she's everywhere. Then Hydra attacked the compound, Tony's got her training, and Bucky hasn't left her side."

"Yeah." Steve breathed. "Something isn't adding up."

"I trust Tony with my life. When we're fighting, I know he's got me. But I don't trust him to tell me the truth. Something about all this stinks." Sam said with a pointed look to Steve. Steve nodded in agreement.

"I'll talk to Bucky." Steve finally said. "See what his side of all this is."

"You trust him to tell you everything?"

"I trust him not to lie to me. If he doesn't tell me everything, then there'll be a reason."

"Compartmentalising." Sam laughed. "Just like Fury used to do. And look how that turned out." Sam pushed off the wall and walked out the gym, leaving Steve by himself.

Steve thought to himself, everything he knew up until this point. A Hydra base in Peru spiked activity. They went to investigate. Hydra attacked the compound. You suddenly became involved in the team. If he didn't know better, he'd say that you were the leak. But Stark seemed adamant that wasn't the case, and he could tell that there was some truth to that.

So the question was, if it wasn't you, then who in the building was leaking information to Hydra?
