Oh? The Nexus just mentioned the idea that the owner of a Holy Grail could be bested in combat and have their grail taken. That was an interesting bit of information. Well, what she understood of Gilgamesh he may have done that, even so, this was something that would need to be addressed by those of current holding. Apparently, the Nexus was only able to interact with people who utilized the key. "I think I understand a bit better now. That is quite useful information," Artoria said. Of course, she couldn't truly figure out Gilgamesh and there were a few others she couldn't quite read completely. That was a problem she could perhaps be helped with, especially given a long term problem she'd been having even before coming here.
More of an explanation was incoming. Apparently, there was a core, granted by the coming of the Queen of Saints, had created in the world a spiritual foundation for people. Saint Graph and Saint Graph Core, were already there and Hoshimi Emi had been the one to make it so. What did Artoria add to the world, apparently a secondary classing which could be used even if she damaged her first. Her own was apparently Paladin, that made sense considering the magical nature of her extra abilities. "I see, these things all make sense I suppose..." she said. What did she want? Her inner assassin said she wanted and needed clarity, and that it needed to be something no one should know. "There is something that is part of me that you cannot touch? How very interesting," she admitted. "If you can grant me what I wish I would like something specific," she admitted. "I wish the ability to discern the true motivation of people when I look at them, but I also do not want anyone to know I have this ability," she said carefully. She looked up quizzically. "Can you provide this? And can I ask for more?"
