It was the date of a meeting with the other Avengers, but your family had called you to come to the grandparents house for some important stuff. At first you tried to refuse it but your father didn't let you. Here you are, in your familial palatial villa, sitting on the couch casually and unbothered, listening to them telling you you were adopted.

Your mother: "Look sweatie, it doesn't change the fact you're a part of the family."

Your father: "Your mother is right. You're still one of us, if you want it."

You look at them, your brother is standing a little farther looking at you. So do your grandparents. Then before anyone can say any other thing your phone rings.
