Everyone knew about Steve Rogers and Bucky Barnes. But what of Steve's unknown sister? She fought alongside the two men during the war. They were all the best of friends, they were family. On the mission to capture the Hydra scientist Arnim Zola, Steve's world was drastically flipped upside down. His best friend Bucky and his older sister James both were "killed" in action. Steve mourned his best friend and sister. You see just as mentioned before no one knew the captains sister, James Rogers. It was as if she never existed. She wasn't included in history books or museums, only in memories did her name exist, that and classified files of course. It came into light eventually that neither Bucky or James we're truly dead. They we're alive. She was alive. This is her story. Natasha x OC!
