S01E23 — The Holy Grail

After the incident at the church, Saber and Shirou return home only to find Rin on the floor and badly injured. It turns out that Kirei Kotomine attacked her, while Shirou and Saber were occupied and that's not all because he has also taken Ilya and plans to make her the sacrifice for the Holy Grail. Aided with Rin's final advice, they both head to Ryudouji where Kirei is going to summon the Holy Grail. Saber will battle again with Gilgamesh and Shirou will have to leave her and deal with Kirei, who obviously has some sort of personal vendetta against Shirou.The final fight has just begun.
