Earths Mightiest Family (REWRITE) [Male Reader x OC]

Family Reunion, yay

"Wait, Sister?" Y/N said as he turned to look confused at the Russian woman.

"Y/N..."

"Does that make her my auntie?" Y/N said as Nat turned to look at him with a glare, he looked to the woman tied up who was giving him the same stinkeye. "Wow, the death glare runs in the family huh?"

Wanda and Pietro looked at each other for clarification only to see one another shrugging.

Y/N walked up to the woman, crouching down in front of her getting face to face.

"Okay, Auntie...what's your name for starters?" Y/N asked as Nat looked worried.

"Y/N get away from her."

"I know, she can kill me with a shoelace or a toenail clipping, if she wanted to. She's had plenty of opportunity to kill me in the last thirty seconds, enough that I'm confident I'd be dead by now. She doesn't want me or anyone else here dead. Do you Auntie?"

"Belova, Yelena Belova." Yelena said as Y/N nodded.

"Lovely name, I'm Romanoff, Y/N Romanoff." Y/N said as he looked Yelena up and down for anything she could use as a weapon. T'Challa came up to him with a red colored vial. "Now Aunt Yelena..."

"Y/N stop calling her that." Nat ordered as Y/N paused to let Nat speak.

"Now Aunt Yelena, what's this, I know it's not a bioweapon because it was handed to me by the king and considering he's not wearing full hazmat gear I'd say it's nothing deadly, unless your the person who has it and the Red Room know you have it. So it's a counteragent of some sorts." Y/N deduced as he examined the vial.

"Tell us what it's for and I can get your sentence reduced." Nat said as Y/N let a sigh out.

"Mother, a Black Widow never gets captured in the field unless they want to defect or trick the enemy, now I have something valuable to them, the're not attacking, meaning that Yelena wants me to look at it, likely to create more. So, Yelena, do you want to help us take down Dreykov?" Y/N said as Nat looked at him.

Yelena looked at Y/N, practically trying to kill him with her stare.

"Look, you don't like me and mum sure as fuck doesn't like you, but if we don't stop Dreykov, we're all going to get kind of beating you don't walk off, so are you up for taking down Dreykov, saving the girls in the Red Room, then destroying the facility, all while making it look like another Tuesday for us." Y/N said as Yelena smirked at her Nephew.

"So, he's yours?" Yelena asked Nat who gestured to Wanda, Pietro and Y/N.

"Yeah, him and his siblings, he's the pain in the ass of the three." Nat said as Y/N smirked like he was proud of the label.

"do I get a shirt with that on?" Y/N quipped as he walked over to Yelena before holding the vial out in front of her.

"Dlya chego nuzhen vstrechnyy agent?[What's the counteragent for?]" Y/N asked as Yelena looked him in the eye.

"How does he know Russian?" Yelena asked as Y/N sighed.

"Him and the Twins were prisoners of HYDRA for fifteen years, they had a lot of spare time to study." Nat said as Y/N raised a brow at Yelena.

"It counteracts the effects of mind control." Yelena said as Nat let out an exasperated sigh.

"Yelena, the sooner you answer the sooner your free." Nat said as Y/N held the vial up again and looked Yelena dead in the eyes.

"She's telling the truth." Y/N said as he approached the edge of the water falls.

"How'd you know?"

"Same way I know she'll help us, she's already against Dreykov, I know because when I do this..." Y/N said as he began to hold the vial over the edge of the falls, Yelena's eyes looked panicked as he pretended to lose grip. "See, this thing is the counter agent to mind control, probably why the girls were so compliant with him while I was his prisoner. None of them tried to fight back, at the time it seemed like they were scared of him or something, mind control just answered my question."
