I still think the 2 boys are unreliable narrators and that Nami spoke & acted differently than they present, but the classic Straw Hat confidence is apparent as the crew calmly discusses chasing Nami while Hawkeye chops the opposing ship into pieces. We see some contrast between Sanji & the general crew attitude when Zoro is fighting Hawkeye and Sanji advises him to “give up your ambition and live!” The Straw Hats are almost always confident in battle, no matter the odds, especially if there is an emotional tie such as Zoro wanting to be the greatest swordsman in the world. Additionally, we have seen Sanji express this same attitude when engaging in his own conflicts. Even Usopp tends to have a very supportive outlook despite being personally terrified of almost everything they encounter. This paradigm is directly contradicted by Sanji’s advice to Zoro, but it is relatable as Sanji is new to the Straw Hats, underestimates them, and doesn’t want them to die, hence speaking & acting out of character.
We heard another reference to the East Blue, in the context of 4 great seas, which I assume are the North, East, South, & West Blues. It seems apparent that the show creators had a long-term vision from the start. Hawkeye’s comment that “you don’t know how big the world is” feels directed at the viewing audience who is only just beginning to witness the enormity of this television setting, and his large cross that doubles as a small sword seems to lead to this understanding, as well. I interpreted it as a bit of a romanticization of a foreign mystic symbol to an Eastern audience, similar to how the yinyang is often represented in Western media, ultimately symbolizing a culture distant from this one in both kilometers & tradition.
Last note, Usopp is such a bard with his quick supply & knowledge of first aid supplies, in addition to his other miscellaneous scattered skills.
