Sayuri hadnt been anticipating the conversation that Kenshin brought up, even if she knew she should have. It only made sense that he would want to discuss her former husband after the last attack had left him so wounded. She was still worried about his health even though his gifts as a vampire had returned and healed him before there had been any truly lasting damage done to him.
"Kenshin..." She spoke softly as she put her utensils down and looked at him. "You cannot honestly be thinking to go and bring the fight to my husband. He's a dangerous man and he will make sure that you never leave his house alive." And then she would be devastated.
