You followed the Avengers through the large corridors of the complex. You stop in front of a door, everyone without turning towards you. Steve takes a key out of his pocket and kneels in front of you, to get to your level and look you in the eyes

Steve: I know you still don't trust us...but it's true when I say we just want to help you.

Steve unlocks the handcuff and takes it off your wrist. Wanda opens the door and you can see a room, it was decorated the way an 11 year old girl would like. Wanda gestures for you to come in

Wanda: We even found out how your power works, we want you to stay here in the complex.

Natasha looks at you worriedly. The Avengers had to capture you, an 11-year-old girl, because your powers were too strong

Natasha: You can come in, the room is yours now.

Tony: And know that there is no way for you to escape.

Everyone looks at Tony seriously
