Found Out

---

As told, Will went to the shooting range the next morning. He had arrived 10 minutes earlier, just in case he got held back and was late. He didn't want to disappoint the assassin, not quite sure what she was capable off.

When he entered the room, he noticed that is was empty, but he also noticed a bag on the ground and a note placed on top. Curiosity got the best of him, so he walked toward the bag, picked up the note and read the, surprisingly, rough hand writing.

Will,

I got called into a meeting with Fury, so I may be late. Inside the bag is equipment that we will be using today. Have a look, test which ones you like, which ones you don't. I should be back at 0930.

Natasha.

Will did as he was told and opened the bag. Inside were many different kinds of melee weapons. Knives, swords, knuckle dusters and nunchucks.

The doctor stared at the weapons, not really knowing what to do. He reached into the bag and pulled out a knife. It felt too heavy, so he got another one out. This time it wasn't too heavy or too light, Will decided to use that one. He had also decided that he didn't want to use the other weapons, they were not his style, (to be honest, none of this was his style).

Looking at the knife he had chosen, he gripped the handle tightly and moved his arm, testing a swing. Will felt uncomfortable with this. He didn't want to hurt anyone but if they attacked Bruce or Natasha, who he had slowly started to trust, even though she was an assassin, he would try and help them, even if that means hurting people. Will would prefer to use a gun because he doesn't have to be up close to the person he is shooting at. With a knife, however, he would have to touch them in order to stab them. He felt sick at the thought of hurting anyone, he was a doctor not a killer.

Putting the knife down and turning towards the gun rack, he picked up the gun he was using the day before and walked to the targets, being sure to check if the gun had bullets, almost dropping the Cylinder. He aimed down the scoop to the men on the cardboard, one eye closed, and fired. The bullet hitting the man right in the neck. Will slowly lowed the gun and stared at the target, almost in horror. If that had be a real person, they would have died. Will wasn't sure if he was ready for that to happen.

Shaking his head, Will raised the gun again, aimed and fired. Hitting the shoulder. Aim, fire. The stomach. Aim, fire. The head. This scared Will, he was getting better, he could kill someone with these wounds. His hands shook.

"Will?"

Jumping at the sudden voice, Will spun around to see Natasha standing by the door, frowning at him as she noticed his expression, "What's wrong?" Her voice was laced with concern.

He looked at the ground, avoiding her gaze.

Natasha then saw the targets behind Will and noticed the accuracy of the shots. All of them deadly. She knew how gentle Will was, so him knowing that he is capable of killing someone must be scaring him.

Romanoff stepped closer to the doctor, who had turned his back on her, "Will." She said in a calming tone, "Will, look at me." Slowly, he turned to face her, still keeping his eyes down

"It's okay." She said, trying to convince him.

However, he shook his head, "No, no, no. It's not okay. I could kill someone. I could kill someone and that's not what doctors are supposed to do. They save people. They save lives. Not shoot bullets at them. I could kill someone!" His wide eyes connected to Natasha's as the possibility sank in. She could see the fear in them. "I could kill someone, Natasha! They could die because of me! I wouldn't be able to live with that! They would die and I-"

Natasha quickly got in front of Will, gently placing her hands on his arms, and looked at him with a comforting gaze, "Will Banner, you won't kill anyone. I promise you that won't happen. You're a doctor, not a murder. All you want is to help people, that is why you agreed to come with me when we first met. You are not a murder."

Will was silent for a few seconds, staring into Natasha's eyes, "So I'm not a monster?"

This surprised the assassin, "Of course not! If anything, I'm the monster, but that's a story for another time." She said, not meaning to say it out loud.

Will frowned but nodded in understanding.

Looking at her watch, Natasha said, "It's 10. Let's have a small break, yeah? After that we should come back here so I can teach you how to shoot at people's legs, that way you're injuring them but not causing a fatal wound."

He nodded silently, his eyes now on the ground, blushing when he realised he had been staring into her green eyes. God, he's screwed.

In the canteen, the assassin and the doctor ate food and had small conversations. But most of the time, they were in comfortable silence.

While they were having another small conversation, Bruce Banner walked in and spotted the two together. He frowned. He didn't trust Natasha, he didn't trust anyone on the Helicarrier, and now his young brother was talking with her. He has tried to keep his brother safe over the years and now he was sitting next to a deadly assassin.

Bruce walked through the canteen, keeping an eye on the two. But as he was about to get food, they started to leave. He followed them. He needed to know if his brother was safe.

He followed them down corridors, up and down stairs until they disappeared behind a door. Bruce stopped outside the door and tried to find a sign of some sorts to know what was on the other side, he came up short.

Bruce decided to go inside anyway. He slowly opened the door.

What he saw scared him.

His young brother. Holding a gun. With Romanoff standing next to him, pointing to the targets and telling him something, Will nodded and went to shoot the gun but Bruce stopped it.

"Will!"

His brother flinched harshly at his voice and turned to see the older brother staring at him, with a mix of fear and disbelief on his face, "What are you doing?! I wanted to keep you away from this, the fighting! And now you're learning how to shoot a goddamn gun!"

Will flinched again at his brother's loud voice, "Br-Bruce, I'm sorry. I want to be helpful. I want to help you if you're in danger. I can't do that by yelling science facts at them, can I? I want to be able to protect the people I care about." Bruce didn't miss the way Will's eyes flicked to Natasha for a second before going back to him, staring at his brother's shoulder.

"I apologise Doctor," said Natasha, "I had offered to help Will, you should be blaming me."

"Oh, I am!"

Romanoff ignored what Bruce had said and continued, "However, isn't best that Will learns how to use a gun? What if we come across Loki and he's still in his murderess mood? How would Will protect himself then?"

"I would protect him."

"You won't be with him all the time. Will is old enough to look after himself."

Bruce was silent. He replayed what Natasha had said to him and he understood why Will wanted to do this. He realised he sometimes treat Will as a child.

"Fine. I'm not happy about this, but you do need to learn how to protect yourself, Will." His brother smiled widely at him, although he wasn't looking into his eyes, which Bruce had gotten used to over the year, "However, Will, I need your help in the lab."

"Oh. Alright." Will said quietly.

Natasha spoke again, "Go, Will. I will let you know when we will have another training session."

The young doctor nodded happily at her and followed Bruce to the lab.

After a few hours, the lab was quiet. The two brothers hadn't spoken at all.

Will decided to be brave and break the silence, "I'm sorry, Bruce." He said, giving his brother the perfected puppy face.

His brother signed, "It's okay, Will. It's-I just worry about you. You're my little brother and I love you."

Will chuckled, "I'm only an hour younger."

"Aww, only a baby!" Bruce laughed, which made Will join in as well.

"I love you too, Bruce. More than anything." Will said, a small smile brightening his face.

Everyone is so caught up on the twins thing and honestly, you're right. Will is definitely a few years younger but I'm too lazy to change it and I can't remember if I had mentioned it again somewhere else so.

Will is at least 5 years younger than Bruce, just ignore me saying that they're twins. Or pick whatever you prefer, up to you.
