Episode Title:
Winter Days, Where the Heart Is.
Episode Description:
After a sparring lesson, Saber notices that Shirou was using Archer's techniques as a basis for study to improve his stance. Shirou arrives late to school and is greeted ominously by Shinji. During lunchtime, Rin reluctantly forces Shirou to eat with her at the school rooftop, where she reveals that she used a Command Seal to prevent Archer from further attacking Shirou during their alliance. Rin tells Shirou that the bloodline of mages of the Matō family died off with each generation. She admits that she recently found out that Shinji was a Master, but she relented in attacking him because he lacked experience in magecraft, which now results in another Master present in the school. Rider activates a stronger magical barrier around the school, which absorbs the mana of everyone except Shirou and Rin. The two are attacked by skeletal beings called Golems, and Shirou summons Saber via Command Seal. Saber battles the Golems while Shirou and Rin go to the school's first floor to disable the barrier. After dispatching several Golems, Saber faces off against Rider and manages to stab her. Rider is revealed to be an apparition created by Caster, who disappears. Meanwhile, Shirou and Rin find Shinji and the corpse of the real Rider, which dissolves, causing the barrier to dissipate. Shinji refuses to identify the Servant who killed Rider and flees the school. After Shirou, Saber and Rin assess the situation and deduce that Caster killed Rider, Rin notes Shirou's ability to recognize the conditions of the unconscious students and employees. Shirou replies that he is used to seeing dead bodies, which confuses Rin.
