Returning home, Shirou Emiya reminisces about the fire that he survived ten years ago inspired him to become a hero of justice. At the church, Caster visits Saber, who is resisting her magical bondage. Caster is then confronted by Souichirou Kuzuki, who learns that her last two attacks had been of her own free will and that she intends to use the church to obtain the Lesser Grail. Rin Tohsaka wakes up from another dream about Archer. The two go to the church, where they find bloodstains, in which Rin concludes that Kirei Kotomine somehow managed to survive an attack made by Caster. Rin and Archer then confront Caster and Kuzuki, but when Rin tries to fight them, Archer suddenly defends them from her attacks. Citing Saber's change in alliegance to Caster's side, Archer pledges his allegiance to Caster, revealing that she is the ancient Greek princess Medea and allowing her to stab him with Rule Breaker, which removes Rin's Command Seals. Kuzuki tries to kill Rin, but she is saved by a recovered Shirou. When Caster counters with Golems, Archer stops her and has her release Shirou and Rin as a condition for him joining forces with her. While on their way back to Shirou's home, Rin confesses that Archer joined Caster because he knew Rin's strategies were hopelessly flawed. Shirou counters by telling her that even though she failed this time, it does not mean she was wrong. After comforting her, Shirou returns the red jewel pendant that he found at her house, telling her that he has another one at his home. When Rin asks why he rescued her, Shirou confesses that he loves her, which initially embarrasses her. However, she thanks him for saving her life.
