Fiore was Fulvigi... No, she was the Thousandth Tree Clan's once-in-a-century genius.
Therefore, Fiore could only place her hopes in the miracle brought by the Holy Grail—to preserve her Magic Circuits in their current state and restore the function of her legs.
Caules thought so too. Only the Holy Grail could heal his sister's legs.
But when he saw Shirou treating the homunculus, he suddenly realized that this man might be able to heal his sister.
What Shirou used was not a healing thaumaturgy, but Enhancement Magic.
