A wide courtyard in Eastern Europe, moments after John Walker has killed someone with the Captain America shield. Blood stains the vibranium. Lemar Hoskins-Battlestar-lies motionless. Sam, Bucky, and you have just arrived, too late to stop it. You, Sam, and Bucky burst into the square. The scene stops you cold. John Walker stands over Lemar's body, chest heaving, the shield dripping red. Civilians scatter in horror, phones recording the aftermath. You can't look away. Neither can Bucky. You (barely a whisper): "No..." Sam (in disbelief): "Lemar..." Bucky's jaw clenches. His fists curl tight, that cold rage bubbling just beneath the surface. You've seen that look before-in HYDRA missions, in nightmares he doesn't talk about. But this is different. This is personal. Bucky (to Walker, voice sharp): "What did you do?" Walker (still breathless, bloodlust clouding his eyes): "I did what needed to be done."
