Jean feels like the Nautilus crew is treating him like a kid and becomes eager to grow up. However, Nemo refuses to make him a crew member, while Electra, and the Grandis gang discourage him even further. Jean is at a loss, until Nadia offers that she has interest in flying again… "only in a craft built by Jean." Inspired, Jean decides to build another aircraft. He aspires to do so all by himself without the help of any grown-ups… a task that he finds more difficult than he anticipated when he can't get an engine to work. Even so, he refuses help from Hanson, straining his friendship with the latter. Later, however, Jean has a change of heart and decides to ask Hanson for help on making the finest aircraft he can. The aircraft is completed, and Jean takes Nadia on a joyous flight above the clouds. In doing so, he manages to impress Nadia and reassure her that he will get her to Africa someday.
