Avengers dad abuse

You're natasha's kid(i know she can't have kids but let's just pretend she can)you and your little sister live with your dad since he earned your custodies by paying the judge. He's abusive to both of you, one day you found a picture of him with natasha and you knew that it was your mom.one day you couldn't take it anymore so in the midnight, you packed your things and your sister's things, and escaped from the window, you ended up with a sprained ankle, but your sister didn't because you used your body as a pillow and let her jump on you so she wouldn't get hurt. You went to the avengers tower hoping she would let you both stay.
