Waver returns to his hideout at the Mackenzie's household. The Mackenzies, whom Waver put a spell on them to made them believe he was their grandson, are actually aware he isn't but they enjoyed his and Rider's company. At Caster's lair, Kirei interrogates Iri about Kiritsugu, believing both of them are similar. However, Iri tells him her husband is nothing like him who is empty 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 sees magical flares from the theater as a sign for 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 to be his Master. Instead, Rider still consider Waver his friend and wants him to ride with him for the battle. Kiritsugu and Saber sees the flares as well, knowing it's a trap to gather all of the contestants at the same area. Having sent the flares, Kirei prepares his fight with Kiritsugu while he sends Berserker to deal with Saber while Archer faces off with Rider. Meanwhile, Iri's soul finds herself inside the Holy Grail.
