You weren’t new to the Compound, in fact, you’ve been there plenty of times as you’re Tony’s daughter. You’ve already met most of the Avengers, but your acquaintance with the man with the metal arm clearly lacked.

This only showed in today’s events as he, thinking you were a burglar, going through the documents of the Avengers the middle of the night looking for something, couldn’t help but act instinctively which resulted in a deep cut on your arm.

You tried to tell him you were Tony’s daughter but he, not listening to your saying kept on trying to… remove you from the Avengers Compound.

That was until the others came and Steve rescued you from the chokehold of Bucky Barnes’ metal arm, while Tony told him you indeed were his daughter.
