Fate Stay night 21th & 22th Episodes

Shirou is talking with Saber when the Servant from the past Holy War appears. Shirou throws himself against him but he's easily defeated. Saber tries to attack him too but she isn't strong enough to stop him. He confesses he's Gilgamesh the king of all heroes when the world was once unified. They both strikes with their Noble Phantoms but Gilgamesh's one is the the strongest so Saber is bowled away and is lies on the ground. Shirou gathers all his forces and stands up, but Gilgamesh says that he has only the power to replicate things and the copies are not as powerful as the original and he wounds him seriously. Notwithstanding this Shirou rises again and with Saber by his side trying to materialize a sword, but he materializes its scabbard, Saber puts her sword in it and that generates enough power to hit Gilgamesh and make him flee. Then there's a flashback where Saber fight with a knight who's asking her to abdicate as 'king' and then she kills the knight who has the same face as Saber and calls her 'father' (?). In the current time Shirou wakes up and his wounds are healed. Saber wants to help him by preparing him the meal but she's too abrupt and thus Shirou helps her. While he's doing it Shirou hugs Saber and says he wants her to stay with him forever when she'll get the Holy Grail instead of redoing the selection as king. Saber runs away but Shirou hugs her again and he confesses his love for her and they kiss. Finally Shirou goes by himself to church to get more information on Gilgamesh, but in the basement he finds many slain bodies and he meets Lancer too that hits him in the chest with his lance.

Saber's speaking with Rin about Ilya's fever that's getting worse and the only thing that can stop it is the end of the Holy War. Moreover she informs her that Lancer's Master is dead and someone who's not a magician took controls of it. Rin wonders if Shirou has gone to the church and thus Saber who's worried about him goes there too. She remembers that in the church she felt the same aura she felt in the sanctuary. When she gets there she has to fight with Lancer, but she's stopped by father Kirei that confesses that he was the person who stirred up the disaster of then years ago by using the Holy Grail even if had lost the Holy War. The Holy Grail is nothing but a weapon that grant wishes by destroying everything in the neighborhood. Kirei offers him to recall the Holy Grail and to repeat the disaster but Shirou denies, so he asks Saber to kill Shirou to replenish the Holy Grail of mana. Saber denies too. Gilgamesh appears from upstairs and he says he was Kirei's Servant in the past war and he used the life of the people Shirou's found dead to get mana. Lancer gets very upset knowing that, Kirei orders both Gilgamesh and Lancer to kill them and goes away.
Lancer ignores his order and attacks Gilgamesh letting Shirou and Saber escape. Lancer is easily killed by Gilgamesh who confess he would have killed him anyway. Outside in the cemetery Saber tells Shirou that his father probably put the scabbard of her sword in him and so he's got regenerative power. Finally Shirou decides with Saber to destroy the Holy Grail.
