Brother!TonyxSister!ReaderxVision Hardheaded

From cool metal to soft earth. The grass brushed against her feet gently. She took a deep breath before turning back to the Blackbird and giving the pilot a large wave.

“Thanks for the ride, Beasty!”

“No problem, kid.” He chuckled.

As the Blackbird took off she walked at a leisurely pace towards the new Avengers Facility.

‘Nice place.’ She gave a small smirk at the facility as she made her way to what she figured was the entrance.

Her toes brushed over an odd patch of ground and she paused. A large intricate circle spread across the ground. She scrutinized it for a moment before shrugging and mumbling to herself.

“Someone isn’t concerned with proper lawn care.”

The sound of a door opening drew her attention to a familiar figure.

“Well if it isn’t little Miss Stark.”

She scrunched up her nose at the man before a large grin dominated her features.

“It’s been too long, Road Runner.” She closed the distance between them and shook his hand.

“You’re telling me.” He wrapped his arms around her.

“Ew affection. You going soft on me?”

Rhodey rolled his eyes and released her.

“Come on. Your brother is getting restless and I don't want another Code Green anytime soon."

She scoffed and shot him an amused glance before strolling towards the entrance a step behind him. He glanced back at her and slowed his pace to match her leisurely saunter.

“I’m just saying, I think you need a way to train the recruits against, say, robots. You know, to prepare them in case another Ultron scenario happens.”

“And I’m just saying that you are not bringing any robots here. For training or otherwise.”

“Come on, Natasha! I promise nothing will go wrong.”

“Just like you promised you wouldn’t blow up that super computer at that conference last week?”

“That’s different. It wasn’t programmed well.”

Bruce glanced up from his book with eyebrows raised.

“What? It’s not my fault it didn’t know the answer to life, the universe, and everything.”

Vision gave Tony a perplexed look.

“Forty-two. It would have been simpler of course to have known what the actual question was.” A new voice drew their attention to the doorway. Tony sprang up from his chair and strode across the room enveloping the girl in a hug.

“I missed you too, tin-for-brains.” She chuckled.

He pulled away and held her at arm’s length.

“I thought you brought the plane down or something.”

“Are you saying you were worried about me, old man?”

She shot him a smirk. He gave her an offended look and crossed his arms over his chest.

“I’m not old. You’re old.”

“At least I don’t behave like a child.”

She mimicked his stance and stuck her tongue out at him.

“Okay, kids, play nice.” Rhodey stepped into the room with a chuckle.

The others that stood in the room assessed the girl with varying degrees of surprise. Her (h/l) hair was messy and fell haphazardly around her face. She had the same cocky smirk that frequented Tony’s face but instead of his eyes, vibrant (e/c) orbs that seemed to glow faintly around the edges gleamed at whatever she gazed at.

She shifted her weight to her right foot and glanced around the room at the few people who inhabited it.

“So I finally get to meet your little friends?” Her eyes swept over them quickly before landing back on her brother. He raised an eyebrow at her signaling that a snarky comment was about to escape him, but before he could speak Rhodey stepped in.

“Steve and Sam are on their way up right now if we want to wait for them.”

“Nah, they’re big boys. We’ll bring them up to speed when they get here.” Tony motioned the girl forward. “Everyone, this is my sister, (y/n).”

“You really couldn’t have waited two minutes?” Sam walked into the room with Steve in tow and shot Tony an amused glance. Before Tony could reply Steve stepped up to the girl.

“It’s nice to finally meet you, (y/n). Tony has told us so much about you.”

She gave Steve a fearful look as she shook his hand and glanced at her brother.

“I sure hope he hasn’t.” Tony rolled his eyes and Sam stepped up with a grin to shake her hand.

“Sam Wilson. It’s a pleasure.”

“Well I guess we’re introducing ourselves now since Tony is pouting.” Natasha stood from her spot and moved towards the growing group.

“I’m not pouting!”

Natasha rolled her eyes and shook (y/n)’s hand.

“Natasha Romanoff. So you grew up with him? I can only imagine the headaches.” The girl laughed causing Tony to pout even more.

“He wasn’t that bad most of the time. He did have a bad habit of catching things on fire.”

Bruce and Clint hovered on the edge of the conversation for a moment before Natasha spoke up for them.

“This is Clint Barton and the one in the hoodie and sweatpants is Bruce Banner. They would have stood there all day waiting to introduce themselves.”

Clint shot her a look before exchanging pleasantries and returning to his seat to fiddle with his bow.

“So you’re Tony’s ‘science bro’ that I’ve heard so much about.”

“Yeah,” Bruce gave her a nervous smile, “he’s told you about me, then?”

“Mhmm, mostly about how you turn into a big green monster. That’s really cool by the way.”

Bruce cleared his throat and tried to find a way out of the situation. His way out just so happened to come in the form of an android.

“I believe it’s my turn to introduce myself?”

The girl tensed up and turned her gaze to the figure that was approaching her. She tilted her head slightly at him. He paused in front of her and for a moment silence filled the room.

“Woah, Jarvis?”

“I am Vision. It’s a pleasure to meet you, Miss Stark.” He watched her, slightly perplexed, as he waited for some reciprocation of pleasantry like the others received.

Instead, the girl disappeared from her place in front of him with a sharp crackle of electricity that caused the hair on Tony’s arm to stand on end. Vision felt a tug on his cape and turned his head to find the girl standing behind him poking at the material.

“It’s so real.” She breathed, her eyes glowing brighter. “How…?”

With a crack she reappeared next to her brother, brimming with excitement.

“How did you do it? Is it an advanced hologram? A robot?”

“Nope,” Tony made a popping noise on the ‘p’ and smirked at her, “guess again.”

She frowned and gave a thoughtful look. The others who had already taken a seat turned their attention to the scene before them.

“If it’s not a robot what could it be?”

“He,” Tony began with a triumphant smirk, “is an android.”

She stared at him for a moment processing the new information.

“But he sounds like Jarvis."

“Yeah.”

She turned to look back at Vision who was watching the two with an almost entirely blank expression with just a hint of amusement.

“C’mon, you can work it out.”

“You know what?” Tony looked at his sister taken aback.

“What?”

“I don’t even want to know.”

Now it was his turn to stare at her and process the new information.

“It’s great to meet you, Jar-ehem-Vision.” She took his hand and shook it, giving him a warm smile. He gave her a small smile in return and she moved past him to join the others.

Tony shook his head and absentmindedly followed his sister. He plopped down on the small sliver of couch that she wasn’t occupying.

For a moment she sat and watched electricity jump between her fingers. Silence reigned in the room once again as everyone waited for one of the Starks to say something. Vision returned to his spot next to the window but watched the girl, fascinated with her behavior.

“So,” all attention turned to her as she began to speak, relieving the tension of the room, “Jarvis got sexy.”

Tony's jaw dropped. Bruce spewed coffee across his book and started wiping furiously to keep it from staining.

“Excuse me?” Tony’s older brother instincts kicked in.

“What?” She looked at him confused.

The rest of the room’s inhabitants had their eyes trained on Vision who stood motionless, staring in between the two siblings.

“Did you just say he was…?”

“Sexy? Yeah, why?”

They stared at each other for a moment. No one in the room moved or spoke. Rhodey shifted awkwardly, the rustling fabric of his clothes seemed to break the trance and save him from having to come up with something to say.

“I thought you would go after Spangles, not…”

“I never said I was going after him. I just said he was sexy.” Her gaze was focused on her bare toes where electricity was jumping from their tips to the metal legs of the table. “Though, I do like a good challenge and since he hasn’t been around for too long…”

“No, stop right there. I forbid-” He let out a loud yelp.

“I’m sorry what was that, bro?”

He blinked at her innocent look.

“I said, I forbi-” He yelped once again.

“What’s up with you?” Now she couldn’t hide the smirk as he glanced at her hand that was pointed in his direction.

“(y/n), I don’t want you-” He jumped up from the couch. “Will you cut that out?”

“Cut what out? I’m just trying to listen to my older brother’s hardheaded attempts to forbid me to do something.”

By this time Vision was watching the altercation with a foreign look in his eyes.

“Me? Hardheaded? Have you looked in a mirror recently?”

Clint leaned over to Rhodey.

“Are they always like this?”

“Yeah.”

At this point, both siblings were starting to get irritated.

“Tony, seriously, even if you forbid me I’m still going to do whatever the hell I want.”

“Not if I lock you in a room.”

“You wouldn’t.”

“Try me.”

They glared at each other before a loud crack filled the room. Tony blinked, surprised at the absence of his sister but turned to find her standing right in front of Vision.

Who was watching her slightly shocked at how close she stood to him. (y/n) glanced over her shoulder at her brother and a silent battle went on between them.

Only the two siblings seemed to know what was going on. Although, everyone in the room had their hunches. Other than Vision of course.

Before Tony could say a word, (y/n) turned back and stood on her tiptoes, wrapping her arms around Vision’s neck and pulling his lips down to hers.

Everyone was shocked. Vision even more so. A strange sensation seeped into his body. His eyes closed as he reveled in the foreign feeling. The warmth of her touch and the electricity that bounced from her body to his cause all thoughts to escape him.

Then it was over.

She pulled away and released him, turning on her heel and walking towards the exit of the room. She briefly paused in front of her brother whose expression was a mixture of shock and anger.

Then she was gone.

Vision straightened up slowly, trying to process all the sensations he had just experienced.

Silence reigned in the room once again.

“That went well.” Rhodey finally spoke earning an incredulous look from almost everyone in the room. “At least nothing blew up.”

The faint sound of music could be heard coming from the rooftop of the facility. The trainees had been wondering what it was and who could have gotten up there all day.

They would ponder the sound for a little while before going back to their duties and shrugging it off as nothing important.

Tony hadn’t searched for his little sister since their exchange earlier. Instead, he spent his time pouting and whining constantly asking anyone who would listen, Rhodey being the only anyone, ‘Where did I go wrong?’ to which the answer would be, ‘She’s a grown woman, Tony, and just like you.’

Which is a pretty accurate answer considering she was the one sitting on the rooftop listening to AC/DC and contemplating how she would make it up to her older brother without coming straight out and saying ‘I’m sorry.’

That is until a certain android found her. He didn’t make his presence known immediately, instead opting for a more sneaky approach so he could gauge her emotional stance at the current time.

She hummed along with the song that was playing and Vision observed just how much like her brother she was. Though, he came to the conclusion that it wasn’t such a bad thing.

“Miss Stark?” She jumped slightly at the sound of his voice.

“Oh, hey. What brings you here?” She cleared her throat and ran a hand through her hair.

“I was hoping to find you.”

Her gaze met his and she cleared her throat again.

“Listen, about earlier...sorry about that whole kiss thing. I just…”

“That is actually what I wished to discuss with you.”

She blinked at him.

“Really? Uh, okay. Go for it.”

He took a moment to go over what he was about to say before speaking slowly.

“Perhaps we could we discuss it over dinner?”

Her eyebrows shot up and she looked at him with surprise.

“Are you asking me out on a date?”

“I believe so.” He looked at her, perplexed with her reaction.

“I believe the answer is yes then.” Her smile caused a warm feeling to spread through his chest and he tilted his head slightly trying to understand what it meant.

She picked up her speakers and walked up to him.

“In guess Tony was right. I am hardheaded.”
