Fate/Zero Season 2 Episode 8

Knight on Two Wheels

As Saber chases after Rider throughout the city on her motorcycle, Kiritsugu investigates and concludes that Rider was not responsible for attacking Iri and Maiya. Saber finds the real Rider and Waver and concludes that they did not kidnap Iri. The two servants duel which results in the destruction of Riders chariot. Meanwhile, concluding that the Matōs were behind his wife's kidnapping, Kiritsugu tortures Kariya's brother who reveals that Kariya was working with Kirei. It is soon revealed that Kirei made a deal with Kariya to kidnap Iri using Berserker's noble phantasm which allows him to disguise as another hero, in this case Rider, in exchange for two Command Seals (which he used to command Berserker to capture Iri) and a duel with Tokiomi at the church. When Kariya leaves, Kirei orders Zōken, who has been hiding and watching them, to come out. Zōken comments that he and Kirei are the same in enjoying watching Kariya suffer before he is driven away by Kirei. Kariya arrives at the church to duel with Tokiomi only to find him dead. Aoi arrives at the church immediately afterwards and becomes convinced that Kariya is her husbands killer. As Aoi weeps for Tokiomi, she angrily asks Kariya if he is happy now. A confused Kariya attempts to explain the situation and places blame on Tokiomi but Aoi reprimands him stating that he doesn't understand her and that he's never loved. Kariya snaps and strangles Aoi; by the time he comes to his senses, he has killed her. As Kariya stumbles out of the church in despair, Archer and Kirei are shown to have been watching from the balcony, enjoying the tragedy as it unfolded.
