Waver returns to the Mackenzie household. The old couple, who Waver put under a spell to make them believe he was their grandson, are actually aware he isn't related to them, but enjoyed his and Rider's company. In Caster's lair, Kirei interrogates Iri about Kiritsugu, who he believes is like himself. However, Iri tells him her husband has nothing in common with an empty man like him, as Kiritsugu is fighting for the Grail to wish for a world without conflict. Disappointed, Kirei kills Iri and vows to destroy Kiritsugu's dream. Later that night, Rider and Waver see magical flares sent up the theater, meant to lure them into a duel with Archer. As Rider summons his horse Bucephalus, Waver decides to use all of his Command Seals to give Rider the power he needs to win and conquer the world, as he feels he is no longer worthy of being his Master. Instead, Rider tells Waver he considers him a friend and wants him to ride with him into battle. Kiritsugu and Saber sees the flares as well, aware they are a trap meant to gather the remaining Masters and Servants in the same area. Having sent out the flares, Kirei prepares for his fight with Kiritsugu, sending Berserker to deal with Saber and Archer to face off with Rider. Meanwhile, Iri's soul awakens inside the Holy Grail.
