Fate/Zero: Season 1, Episode 9

1 - 9: Master and Servant

Kayneth wakes up with his body tied to a bed. Sola tells Kayneth that his Magic Circuits were destroyed by Kiritsugu's bullets and he can never use magic again. At Sola's mercy, Kayneth has no choice but to relinquish Lancer's command to her. Despite Sola becoming his new Master, Lancer wishes to remain loyal to Kayneth, but Sola convinces him to keep fighting with her, using Kayneth's honor as a pretext. Kiritsugu decides to hunt Kayneth down despite Saber and Iri's wishes to stop Caster. Meanwhile, Waver and Rider manage to find Caster's lair, where they are horrified to see the mutilated bodies of his victims. Before setting Caster's lair on fire, Rider kills an Assassin targeting Waver and drives off two more. With Waver and Rider now knowing their secret, Tokiomi orders Kirei to send his Assassins to spy on them.
