The scream and blind panic both startle Riku, so much so that he backs off to give Ienzo some space. What is he so afraid of? Sure, Riku had defeated him back then, but Zexion had escaped. Was it his mastery of darkness he'd displayed back then that frightened him... or something else?

"Hey," he says, spreading his arms, slowly, to show he's unarmed. No weapons, no darkness, nothing. "You don't have to be afraid of me. I'm not here to fight anyone."
