I know that there will never ever be a Taiga route, but man, how I'd love one where Shirou realizes that he views Fuji-nee more like a woman and less like a surrogate older sister and Taiga realizes that she kinda wasted her time chasing a wild goose named Kiritsugu and at first unconciously transferring her feelings on Shirou before accepting the fact that she genuinely loves him as a young man more than she likes him as a surrogate younger brother.
