Charles overall idea seemed to be to show up, without weapons or outward forms of aggression. To potentially hand over a peace-making gift, in this case, temporarily his Holy Grail to be used as a sign of trust and respect. And to use that entire situation to get his group ingratiated to the other. "I really have no idea how you came to this set of conclusions," Sakura started. "But the plan itself doesn't sound like a bad idea given human emotions are at play," she finished up seemingly amazed by the well-thought out plan basically brought from nothing into something that seemed somewhat reasonable. As for the extra bits associated with his question about why he could or could not hand over his grail, she gave it a bit of thought. The only technical problem she could see facing the lad would be the transference of the grail leading to a shift in a grail babies parents. But after seeing Angelica within the space, she was sure that the young goddess of Justice would be birthing Charles's Grail, Jeanne would be giving birth to her own, and Sakura would be birthing her own. Given this it would be rather simple to temporarily surrender custody of the item without handing it over in the more permanent sense. "Given the way I constructed my own grail, I would say that as long as you don't intend to permanently pass on your grail, it would be no problem to hand over the physical cup. All the potentially problematic magical issues aside from you giving it away in truth have already been settled," she finished her thought and gave a gentle nod.
Still she was observing the friend group's interactions and wondering how far back they went. She didn't fully understand all the terms, but at least the other two studious ones were still paying enough attention to keep track of what she'd said. This was made immediately obvious by Anais, "Well, if it's possible for you to not accidentally hand it over it would be fine. I know it's a very powerful artifact so you should be mindful of handing it over, but if Sakura-chan doesn't think it will be a problem then I think it will be fine. Also we could technically offer to help them before we do what we need to do, they are probably in a bit of a bind without their leader around," she added. At the mention of her name with a simple but familiar honorific Sakura smiled, perhaps she was making casual progress towards her desired new friends.
Just the same Astolfo seemed to be realizing that Anais was apart of the friendgroup of his younger sister, and had taken to poking the bottom of Yume. In her own kind of flirty manner she brushed back against it and laughed just a bit. "Come on now, the horse is nice but that poking isn't it~" she mused just a bit. "As for which one she is, this is Iino Miko, the Student Council President, former Iron willed little empress of the Disciplinary Committee, our Party Mom, you know the one we have a bet going on whether or not she has a secret boyfriend or she's like Daft Punk? Come on you have to know her~" she held her hand against her chest and turned so that she could motion about how tiny the girl was in their previous world. She was the friend stationed front and center in all their group photos so she didn't get lost. "Waah, wait wait wait, can we not talk about this right now?! Charlie's trying to give a speech!" Anais seemed to be rather aghast and her face was now redder than even it'd managed to be during the whole Mugen fiasco the previous day. And she was deflecting very hard, but this was all very normal activity for her. She really wasn't prepared for anything else today, their most invasive friend spilling her entire identity was well beyond normal.
