Artoria, no... Hoshimi Eri had three siblings and of the three only two would claim to fully understand her motivations. The eldest of their group, Hoshimi Rie, who shared her goal, but not her disposition. And Hoshimi Emi, who understood, but was encouraging her older sister to be a bit more selfish of herself. Imagine a saint telling someone else they were too selfless, that whole thing was laughable. So laughable, in fact another smile crossed her face and she simply shook her head. Irrespective of anything else, he was willing to drop subjects that were not fruitful to him in discussion. Good, he couldn't be reasoned with but he'd at least stop speaking from time to time. That would make any future alliance with him, not quite as annoying as it could be.
Or, maybe not. It would seem the King of Heroes was a bit coy with her earlier understanding and looking into Artoria's build. He was certain of a thing, but it was not the normal type of certainty. It was instead it was the certainty of Clairvoyance in whatever way it manifested in those strange eyes of his. Artoria, honestly scoffed in this moment. He spoke of impossibilities, things that were legitimately impossible. And more over, he made several claims about the situation which made her nod her head in simple understand while she stared fire at this man. "That is the annoyance. Clairvoyant and assured. That damned mage..." she stopped speaking and closed her eyes in the moment. But what was she seeing in her own mind? The annoyance in her life that was Merlin. In fact, this very meeting was occurring right now because that sulky, annoying, clairvoyant mage would not reveal the direction she should point her sword. After almost a fortnight without sleep, the aggravation and lack of comfort had gotten so bad, her walk had ended her, here. At a dinner table, with Gilgamesh. She rather suddenly had the desire to draw her sword and end every single clairvoyant individual who had ever stated random facts of her life to her as if dictation. But what would she say? "There is nothing wrong with chasing dreams. Yours however have many impossibilities weaved in... like the fact that I am permanently fifteen years old, barren and I am going to die. These are absolute facts. You never stopped to consider the idea that those are likely one of either of my sisters' children as we all share a face? Nor the idea that you see my face in things because you simply wish to?" she questioned this before adding in the other thing. "There is also the fact that I still am annoyed by you, and I would see no purpose in marrying someone who annoys me." Artoria gave the most absolute version of the truth she could because there was no reason not to, she could understand him. Speak to him, even help him a bit while he grieved, but there was no option in her future where she could marry him... even if she wasn't barren, she was uninterested.
Ah, but somewhere, there was as silver haired woman with cold blue eyes and a hard expression who, indeed shared Artoria's visage. Her little sister's words in those moments as she saw a vision of them clicked into place the answer to the ultimate question. "You really should do something about that bad habit, little sister. Though, I can not complain since I now understand how you are truly. Do not worry, I can think of at least one reason to connect yourself to someone who annoys you, and even to bear his children!~"
