ตอนที่ 4: เซเบอร์และแลนเซอร์ต่อสู้กัน ขณะที่คิริซึคุสอดแนมหามาสเตอร์ที่ซ่อนอยู่ และอัสซาสซินรายงานผลการต่อสู้

Saber and Lancer fight, while complimenting each other on their skills and chivalry. At the same time, Kiritsugu and Maiya are scouting the battle, with Kiritsugu spotting Lancer's hidden Master. As he is about to snipe him, Kiritsugu spots Assassin, who is relaying the battle to Kirei and Tokiomi. Lancer's Master orders him to use his Noble Phantasms, Gae Dearg, the anti-magic spear and Gae Buidhe, the cursed spear that inflicts wounds that cannot be healed. From these, Saber recognizes Lancer as Diarmuid of the Love Spot, while Lancer discovers Saber's identity after using Gae Dearg to temporarily dispel the invisibility spell on her sword. Saber, whose left tendon was wounded by Lancer's Gae Buidhe, is about to give it her all when Rider, who was watching the battle from afar, suddenly rides down to the harbor on his chariot, interrupting the battle. (Source: Wikipedia)
