Dreams
Some of the crew loves fishing, some more than the others. No one has never really ever stopped to think why. It is obvious that to some it gives pleasure to catch something, sometimes after a long wait. It also provides them the food they need, so it is fun and work merged together, like it often is with their crew. And they are at the sea, so of course they would do some fishing! Who knew, maybe one day they would catch an enormous sea king and then have a proper feast with lots of meat and singing – and drinking, in some cases. They have never stopped to think the possibility that one day they might catch a lot of fish not only native to that particular part of the sea, but from the other seas as well. They might love fishing so much because in their hearts they want to help Sanji to locate his dream.
Luffy is always enthusiastic to go to all the oddest unmapped places they could find. At times a feeling of adventure is enough for their captain to point out a direction he wants to head off to, and – nowadays – not to their surprise they would find someplace absolutely weird and unvisited, just like it was supposed to be. There would be no adventure to that, otherwise. If it looks dangerous they will protest, they always do, though they know it is for naught. They could keep arguing or just stay behind, but they rarely do, and then they somehow get dragged all around the place. But visiting the unknown is the only way for Nami to complete her dream.
Going in the new places, exploring, it all takes time. They are never really in the hurry – unless it's about saving a kingdom or the world or something as trivial, you never know what little errands you have to run when you're a pirate. They check every corner while looking for a treasure, whatever it might be on that particular island. Each has their own view on what's treasure and what's not. What might seem just another rock on the ground might be something much more. Eyes wide open in case there's something that someone in the crew really wants they stroll around. Because any old ruin or rock with odd text could be the one Robin needs to complete the puzzle and any regular looking flower could be the herb that takes Chopper so much closer to healing any and all the diseases in the world.
Being a pirate is dangerous by itself, but being a pirate on Thousand Sunny, being in Luffy's crew, is like calling the danger with the loudest shout and largest flare. They attract trouble – or they are attracted to trouble unconsciously. They all don't love to be face to face with their potential Reaper, but what else could've they expected when they left their previous lives to become wanted criminals. Once they step somewhere they can always tell something will be after them. If nothing happens, it's just because Luffy is sleeping. Even eating could draw trouble with him. But in the end, regardless all the complaining and screaming and running and whatnot, that danger makes them more and more ready to face whatever is thrown at them, and this is how it is supposed to be if Usopp ever wants to become the brave warrior of the seas.
Sometimes the danger doesn't stay on ground but finds them on the open sea instead. Fighting is a bit different from that done on a more stable footing, but having lived on the sea for so long, the Straw Hats don't have trouble. They slash, hit, hack and kick their enemies away. Not all enemies are breathing and walking on one, two or more legs or moving by some other means, however. Sometimes they have to deflect the cannonballs to protect their largest nakama, Thousand Sunny, who carries them from adventure to other. She is strong, more fit for these seas than their previous ship Merry had been. They miss her greatly but that doesn't mean they don't love Sunny: she is just as much a part of the crew as Merry had been. So they protect her so they wouldn't have to go through another tragedy that is funeral for a ship. While at it, they also protect Franky's dream as well. Also, if there's no ship, there's no way for Brook to finally meet Laboon again.
And when it comes to protecting, some do it more than the others. No one minds, they are supposed to keep each other safe. Taking hits meant for others comes naturally, no one wants their nakama getting hurt, and if someone is capable of taking more damage then there's no question whether it should be done. Strong do not eat the weak in here, the strong protect the weak so they can become stronger on their on pace. They're just thankful to be able to see another day together, and being saved isn't really that bad. And when Zoro does the protecting, it just helps him on his way on getting not just better, but the best.
Through all the crew does its best to protect and help one another. They are ready to sacrifice themselves, though they do choose life over death anytime so they can keep being there for each other. When the world doesn't throw adventures and dangers at them, they take it easy and enjoy the company they have. They bond, perhaps not seeing it themselves, but every word and action strengthens the string that bounds their lives together, even if only slightly. They have their disagreements, but to be able to bring them out is just another way for them to show trust: they don't have to fear they'll be left behind for their opinions. After all, the future Pirate King's family has to be tight-knit through it all.
