As a result of Nadia's foolishness, the children only have meat for food. This infuriates Nadia so much that she declares to starve... until she becomes desperate to eat a can of rotten spinach, getting sick. Jean sets off to find a cure, only to become intoxicated by hallucinogetic mushrooms(!). Overwhelmingly grateful, and stupidly unaware that Jean is not himself, she gives him his first real kiss....

Gargoyle's battleships appear over Tartessos. To save Jean and the others, Nadia surrenders herself... but not before Jean swears to save her. Forced to flee from Gargoyle's battleships, our pals run into Captain Nemo and his crew, who have survived... and now operate a superpowerful battleship called the New Nautilus.
