Sakura and Shirou
As soon as Sakura made her move, the blonde servant stepped in, grabbing hold of her hands and stopping the attack. Sakura glared angrily at the servant, but she knew there was nothing she could do, especially given that she appeared to be able to completely nullify her magic. Her shoulders sagging slightly, she simply continued to glare, hoping that the servant or her master would not decide to finish off her helpless husband.
Shirou, meanwhile, continued to struggle to stand.
Sakura is in danger! he thought, desperately, struggling against the white-haired woman holding him.
Before he could do anything, however, the alternate Sakura spoke.
"Apparently, this fool never uncovered his true nature, and still naively trusts him, like a child", she said, seemingly talking to Jeanne, presumably continuing an internal conversation. "It must be unfortunate, to find out your beloved is worse than an axe murderer. I'm truely sorry."
Sakura felt a combination of sadness, irritation and anger at the woman's words. Her willingness to openly slander Shirou and the way she was talking down to the much-older version of herself was seriously grating, but the empathic tone blunted Sakura's anger a little. It was clear that the woman meant her no harm, and was simply seriously mistaken as to Shirou's nature.
Whilst Sakura did not like seeing someone misjudge Shirou in this manner, she could understand it to an extent, even if she was surprised at the unwillingness of the alternate version of herself to give Shirou the benefit of the doubt, as she knew she undoubtedly would have. He had made a serious mistake, and compounded it with an inexplicably bad apology. And, besides, despite her obvious anger, Sakura knew she was heavily disadvantaged. Shouting at or insulting the woman would not help her, all she could do was try to convince her to see reason.
"Sakura, Shirou is not a monster. He simply made a mistake, one which he was about to apologise for. Properly", she aaid, glancing at her husband, who was gradually struggling to his feet, hoping he would soon get to it. "Please, do not hold his mistake against him, or against me."
It was obvious that Sakura was angered and upset by what she had said, but she held it in. She just wanted to protect Shirou, and avoid causing a conflict between herself and Rider's new master. She knew that her beloved servant would be heartbroken to see the two of them fighting, and it was something she desperately wanted to avoid.
Shirou, having struggled free of Irisviel's grip and unsteadily risen to his feet, stood straight up and walked towards the alternate Sakura, only to immediately throw himself to the floor again. Prostrating himself before her, he began to speak, his voice full of regret and distress.
"I'm sorry for kissing you! I'm sorry! I'm really, really sorry!" he said, his anguish obviously genuine. "Please forgive me! I'm really, really, really sorry!"
