You're a freak, a man made freak. You became an experiment against your will, the result is the two enormous wings attached to your back. You hate them and what they stand for, bulky, awkward, and clumsy. They and the scars that litter your back are a remind of how cruel people can be. When you've finally had your fill of self pity you contact the man that saved you, Tony Stark.
Bucky see you late one night while everyone is out on a mission. All he wants is to get to know you, and to help you see that you aren't the freak you think you are.
