The Avengers

You are sat at the back of Natasha's office with a book, curled up on in a chair as you read while she works. All of a sudden, someone knocks on the door, and you freeze in panic, as you know she hasn't told anyone about you yet. She looks at you with a calming expression and walks over to the door openening it to reveal a woman with a dark red suit with brunette hair standing in the doorway Wanda: Natasha, you're finally… Nat, who's that?
