Ulysses went through many experiences before meeting Nausicaa and his servants. These experiences showed him that not everything is resolved on the basis of force, but many things are resolved in a less radical way, especially when you are in a strange territory, alone and without allies.
The moment when Ulysses faces the Neptune storm is a moment when he is proud, proud and arrogant for being a great and victorious warrior. At that moment Ulysses is immature and this provokes the wrath of the gods. However, when he encounters Nausicaa, that arrogance is no longer so evident, due to all the difficulties he faced along the way and which became much more difficult due to his immature behavior. That is why at that moment, Ulysses decides to act cautiously, which shows a great maturation of the character. This caution is the result of the unpredictability of the region and of the events, which Ulysses has learned to respect.
