My conspiracy theory is that the Prisma Ilya universe is the result of an untainted Grail granting Sakura's wish for a life that provides a PG-13 romcom between her and Shirou and the rest of the setting is the arbitrary details to support that.
From that, I predict mysteriously dead Zouken, and that she's being raised properly by Uncle Kariya.
