Episode Title:
Unlimited Blade Works.
Episode Description:
Gilgamesh mocks Shirou with his ideals after the latter is largely incapacitated by the effects of Ea. Although Shirou admits the flaws in his idealism, he reaffirms his dream nonetheless. Saber arrives and blocks an attack made by Gilgamesh, but Shirou orders Saber to save Rin instead. Having an epiphany about the true nature of his powers, Shirou activates his Unlimited Blade Works and uses its infinite number of replica swords to counter Gilgamesh's Gate of Babylon. Meanwhile, Saber approaches the Holy Grail and recognizes it as a corrupted Servant called Angra Mainyu, which has been summoned improperly. She locates Rin, who uses a Command Seal and orders Saber to destroy the Holy Grail with Excalibur, as Rin is being consumed by Angra Mainyu. When Rin loses hope of surviving, Archer's voice reprimands her for giving up, and a barrage of swords strikes Angra Mainyu, freeing her. With Rin free and using her final Command Seal to augment her attack, Saber unleashes Excalibur, destroying Angra Mainyu and the Holy Grail. As she fades, Saber admits that she would have liked to stay with Shirou and Rin, but accepts that her role is over. Inside Shirou's Unlimited Blade Works, Shirou begins to overwhelm Gilgamesh, who furiously draws Ea, but Shirou severs Gilgamesh's arm and slashes his chest before running out of mana. Gilgamesh, grievously injured but alive, prepares to finish him off, but a portal to the Holy Grail opens and engulfs him. He ensnares Shirou with Enkidu in order to pull himself out, but Archer, having survived Gilgamesh's previous attack, intervenes by shooting a dagger into Gilgamesh's head, fatally wounding him. As he speaks his last words, Gilgamesh is consumed by Angra Mainyu before the portal closes. Rin and Archer say farewell as he fades away, with Archer asking Rin to look after his past self. Shirou reunites with Rin, and they walk off together as a couple.
