The girl with no name. That's all the Winter Soldier knows of the girl. She had been frozen ever since he was captured. He doesn't know who she is. She doesn't know who she is either. Neither of them know who they are. All they know are their missions. They train together, they fight together, they are wiped and frozen and tortured together. When the two are ordered to eliminate Steve Rogers, the first domino is tipped, tipping over more and more until the two begin to remember pieces of their pasts.
