Sakura and Shirou
Sakura looked at the woman with a mixture of concern and scepticism. She wasn't sure how this woman knew her sister but, from the sounds of it, he had met the version who was with the other Sakura, who was, presumably, quite a bit younger than her Rin was. Further, she didn't share his low impression of her sister's capabilities. After all, her sister was close to achieving true magic. If Rin said she could send them here and back, Sakura was sure she could.
Before she could reply, however, the woman continued speaking, addressing the "future omens" part of her question. Part of Sakura was intrigued by the response, but another, much larger part concurred with Julius' statement. Her future was her own to determine, and whatever this woman had to say would only act to divert her from that.
"Thank you for your offer, but I trust in my sister's ability to bring us home. I believe the version you met of her is far younger, and therefore far less knowledgeable. Further, I do not want to return to my home dimension without Rider unless it is absolutely unavoidable, so for now I would rather stay.
As for my omens, I agree with Julius. Our future is for us to make, and asking you to predict our fate will only push us away from the path we wish to take. Sorry, but I will not take you up on that offer", she said.
