A few months after Natasha sacrificed herself to save the world (with her hero friends), her adoptive sister Yelena was given a mission to kill you.

However, she doesn't know who you are exactly because Natasha didn't have time to tell her about you.

You know who Yelena is, what she looks like, and what she's like. Natasha found you, talked to you, and spent some time with you.

That evening, you were attacked by her. It was Yelena. She found you. Yelena's assignment stated that you were involved in Natasha's death, but that's obviously not true. You weren't even there.

Yelena beat you and didn't let you speak. She kept blaming you and saying you deserved it. There's revenge and hatred in her eyes.

After a while, while you were sitting on the ground, she pointed a gun at you. You both looked at each other catching your breath.

You: You can’t do this.

She raised an eyebrow slightly, amused by this.

Yelena: Oh yeah? Why?

You: Becouse of Natasha… She was my biological sister.

Until now, nothing could stop her, but after what she heard… She just froze, looking at you in surprise and slight shock.

Yelena: What?…

She whispered, her heart beating faster. Yelena began to think and asking herself a multitude of questions. She couldn't have killed you. You're Natasha's only biological family, and now… her adoptive siblings.

She slowly lowered her gun, never taking her eyes off you. Family is the most important thing to her, and she's always wanted it. However, she needed proof that you’re not lying. She decided to give you a chance to do just that.
