Bucky is an Avenger now, he just got saved from hydra. He gets nightmares all the time, Steve told him there is a girl in the compound that was at hydra as well, Jaz. Jaz is Tony's 24 year old daughter, she was 'shadow soldier' and is a very good assassin. Bucky never met her, not yet anyways. Everyone tells him Jaz is cold and emotionless still. Bucky had a nightmare and walked to the training room, then sees Jaz and immediately falls in love as he watches her train.
