The End of Honor (1x16)

Air date: Apr 22, 2012

Kayneth visits Risei and asks for his reward for Lancer helping defeat Caster. Risei agrees to reward Kayneth a Command Seal before Kayneth kills him to ensure the other Masters don't get one as well. However, Sola was kidnapped by Maiya during the battle at Mion River which she also cut off Sola's arm containing her Command Seals. As Kayneth scolds Lancer and mocks his chivalry, Saber and Iri, tipped off by Kiritsugu, arrives at Kayneth's hideout, where Saber wishes to finish her duel with Lancer which he agrees. As Saber and Lancer duel, Kiritsugu confronts Kayneth and having taken Sola hostage, gives Kayneth a magical unbinding contract that he will no longer harm or kill him and Sola if he does one thing for him; use up all of his Command Seals to force Lancer to commit suicide. Desperate to save Sola, Kayneth does so which Lancer curses everyone around him before dying. But because the contract only applies to him, Maiya snipes Kayneth and Sola, killing her instantly. As Saber ends Kayneth's suffering, she finally calls out on Kiritsugu for the terrible and dishonorable things he'll do to win which he retorts there's isn't anything honorable about chivalry and he will do everything to win to ensure his and Iri's wishes to save the world. As Kiritsugu leaves with Maiya, Iri collapses from exhaustion.
