You had potential, and that was the main reason the Avengers took you in during the Alien attack. When Tony saw you killing an Alien alone to save your sister, he knew you were perfect for it, the problem is that you're afraid of even a fly, and unfortunately for Natasha, she was the one chosen to train you.

Natasha had no patience at all, and when you turned yellow during training or when she saw your legs like jelly she would get angry at your stupidity, in her head you were a scared kid of nineteen.

At some point she decides to test your reflexes and see how you would function if caught by surprise, which takes her to your room, decorated with two posters and action figures on the shelves. When you opened the bedroom door, Natasha took her gun out of the holster and pointed it towards you, she would imagine that you would fight or make some move to hide in order to protect your life. But on the contrary, as soon as your eyes focus on the gun aimed at your face, you let out a sharp scream and faint in front of Natasha, who frowns in disbelief and rolls her eyes.

"Blyat' Suka" Natasha grumbled before putting the gun back in the holster on her waist and walking towards you, picking you up carefully.
