After burnside was arrested, he and his deputy, the third Bucky, were put into the hibernation cabin. Later, the person in charge of guarding them was dissatisfied with the reality and let them out. They didn't know the news that Steve had thawed back from the Arctic Ocean, thinking that Steve, the active American team at that time, was an impostor, so they tracked Steve and Sharon, who were on vacation in Miami, and tied them together with the falcon who came to the rescue.
