Steve Rogers and Nick Fury begin planning one final mission—to track down the Winter Soldier and end the chase once and for all. Fury assigns Clint Barton and Natasha Romanoff to aid Steve on a covert operation: infiltrate a Hydra airship storing intel on supersoldier camps. The trio battles through Hydra agents, reaching the core to retrieve coordinates for multiple camps. Steve and Natasha are sent to one in Eastern Europe—where James “Bucky” Barnes is guarding. As they enter the camp, Bucky finds them instantly. Seeing Steve triggers something. Memories. Mercy. Friendship. “You shouldn’t be here,” Bucky warns. “We came to free the soldiers,” Steve replies. Reluctantly, Bucky leads them deeper into the facility. But before they reach the cells, a shadowy figure drops before them. “I am the Grim Reaper,” he says coldly. “Your betrayal is unfortunate, Winter Soldier.” Steve stands firm. “James isn’t your weapon. He has a choice.” The Reaper attacks. Steve and Bucky fight side by side while Natasha releases the captive supersoldiers. United, they overwhelm the Reaper. Before retreating, he warns, “If you run, Hydra will never stop hunting him.” The soldiers escape. Back at base, Fury places Bucky in holding—for protection. Fury turns to Steve. “There’s someone you need to meet. A man named Sam Wilson. One of those freed soldiers… was his brother.”
