You were one of the original 7 avengers and ever since Steve rescued Bucky he hasn’t liked you, or that’s the impression you always got, so you left him alone. Eventually you two started butting heads and not getting along and kind of “hated” each other. Neither of you know that inside it’s because you have feelings for each other and feel rejected. Anyways you and Bucky got paired on a dismantle mission of a hydra base in Yakust. It was supposed to be a simple mission. It wasn’t. There were too many men, more than you accounted for, and they must’ve had a tip off because while they were actively kicking your asses they were also destroying your safe house so you had no mode of contact back to the avengers. When the fight was over you came to, a blinding pain in your leg. The bone had to be nearly shattered. None the less you had to find Bucky, and you did, he was shot through the lung struggling and gasping for breath as the soldier serum fought to heal the wound.
