There are so many layers of bluffs & deception in this episode that it is almost difficult to keep track of them all. Nami is clearly torn between her false loyalty to Arlong in an effort to save her hometown and her newfound love for the Straw Hat crew. Usopp is simply saying anything he thinks will save his life. Zoro persuades Octojohn that he is a guest of the fish people and not their prisoner. Arlong tries to catch Nami in a lie before revealing that he pilfered her private room. It also seems that Johnny is unintentionally spreading misinformation about Nami murdering Usopp in cold blood without understanding the ruse, which is obvious for the audience but clearly convincing to all onlookers.
This level of false communication is indicative of many problems in society when individuals feel they cannot reveal the truth for a multitude of reasons, not the least of which is pure survival. Avoiding conflict, or attempting to gain the upper hand in a conflict, often involves less than scrupulous behavior, particularly on the part of who either has the most at stake or who has the disadvantage. Interpersonal relationships are typically convoluted to begin with, but when several parties with a range of goals & motivations are all trying to manipulate each other into specific actions to aid their own cause, these difficult dynamics become even more nuanced & unpredictable.
I personally find Zoro’s interaction with Octojohn to be the most compelling. After escaping his restraints and slaying the guards, he is unsure of his next move until he encounters the octopus guy fishing just outside the gate, but then immediately takes advantage of the situation with quick-witted cleverness. Octojohn’s hubris, believing that no one could escape their captivity or defeat a fishman, makes this gambit easily successful and is an example of misplaced confidence. He doesn’t even check with anyone else or make any effort to investigate the compound before just aiding Zoro in his adventure, assuming that if he is walking free in the fish people’s headquarters, surely Zoro belongs there because everyone knows how dangerous it is and would never enter or hang around unless they had express permission to be there.
Last note, it saddens me that Luffy & crew have not only harnessed the sea cow for their own purposes but also eagerly push it beyond its physical capacity to the point of painful exhaustion before just abandoning it. This mentality that humans hold towards non-human creatures continues to bother me, particularly from the protagonist characters that are typically so committed to freedom & equality. This mirrors reality where the use & abuse of animals for all sorts of purposes isn’t even considered to be slightly problematic or worth discussing, and I still hope we will see these concepts developed in future episodes where the Straw Hats begin to form more meaningful relationships with the animals of their world.
