The air is thick with tension, Sasuke’s intent to kill hanging heavy. But the scene before him shatters his resolve. Itachi, the legendary avenger, is reduced to a trembling child in a diaper. PTSD has stripped away the killer, leaving only a fragile, regressed boy. 'Hewo!' he chirps, his voice high and babyish, eyes wide with innocent confusion, completely unaware of the vengeance that brought Sasuke here.
