you were taken by Hydra a while back when working with the Avengers. Steve and Tony finally found the base you were held captive in. They rushed to Alexander Pierce’s lab and start asking where you were.

Alexander Pierce: “Woah boys settle down.”

Steve: “You made a genetic hybrid, raised in a lab. She does not even know what she is.”

Tony: “she will kill everything that moves. She is learning where she fits on the food chain and I’m not sure you want her to figure that out.”
