Kuma, battered and without free will, approaches Bonney. Overcome with emotion, she tells him she saw all his memories and learned everything that he did for her. Watching the scene, Vegapunk wonders what compelled Kuma to come to Egghead.

As an order comes down to evacuate the island in preparation for bombardment, Navy soldiers rush to their ships. Meanwhile, Vegapunk pleads with Saturn to halt the attack, arguing how vital the island is for the future of humanity, but Saturn refuses to listen.
