Summary
Speedwagon notices Dio, and remembers the death of George Joestar and become enraged at Dio's past actions. Jonathan also has the image of George’s death in his mind. The young boy remains baffled by the events, and Jonathan asks for his name. The boy tells him that his name is Poco. Jonathan tells Poco to get on his back and hold on to his backpack straps, as the trio prepares to fight a hoard of undead knights. Jonathan and Zeppeli are armed with only their knowledge of Hamon, while Speedwagon takes up a sledgehammer to defend himself. They are able to fend off the hoard, and eventually Zeppeli confronts Dio, who is still observing them from atop a rock structure.

Zeppeli tries to get Dio to come down from the rock to fight him, but Dio refuses to do so. Zeppeli jumps into the air and attempts to destroy Dio with his Sunlight Yellow Overdrive, but Dio counters by freezing Zeppeli's arm, by vaporizing the water in his arm. Zeppeli's arm splits open, seemingly unraveling itself, almost cause him to compromise his breathing pattern. Dio prepares to crush Zeppeli's head with a punch, but Jonathan intervenes and blocks Dio's attack.
