Jinbe apologizing to Lucci is VERY interesting to me.
Jinbe is a Warlord, and his diplomatic skills and knowledge of power structures is so thorough that Topman Warcury was impressed enough to comment directly on Jinbe's efforts bridging the gap between Fish-Men and humanity.
Jinbe should be WELL AWARE that Lucci and Kaku are slaves to the WG.
Lucci is a murderous asshole, but that's how he was raised. I'm going to be putting a theory out on this, so, I won't go full into detail, but Lucci to me is a product of Garling and Garp.
Like Garling, Lucci enjoys "hunting" people for sport. He's filled with a natural bloodlust, that was only ehnanced by his Carnivorous Zoan.
Garp and Garling are enemies, and hate each other. Garp is known to protect everyone he views with respect, even mountain bandits like Dadan. And Garling?
"Stand up for sub-human scum, and you sink even LOWER!"
IMO, Garling kidnapped Dragon's wife, Laffy, the forced her into a marriage. Garling did the same with Ginny; Garling wanted to "complete the hunt" by killing Ginny, and used Bonney to lure Kuma to Saturn. So, Garling intentionally infected Bonney with Sapphire Scale, because he knew Kuma would have to seek out Vegapunk, the only person who can cure the disease.
Garling did the same with Laffy. Dragon was a Marine who saved Luffy's mom from a human hunt held by Garling in the Goa Kingdom. This is what caused the creation of Gray Terminal in the Goa Kingdom in the first place. Dadan is most likely also a survivor of this hunt.
Garp named Dragon after the Celestial Dragons to piss them off. We know Garling hates this, as at God Valley a Celestial Dragon stated that people naming things after the gods pisses them off. Garling hates Dragon JUST BECAUSE HIS NAME IS DRAGON.
Since Garp and Dragon were in the Marines, Garling couldn't touch them.
So, Garling annexed Goa Kingdom, held a hunt, and tried to murder Laffy, Dragon's wife. Dragon, furious, fought back, and was enslaved along with this wife in Mary Geoise. Laffy died giving birth to Luffy, Garling's son, and Dragon, in rage, rescued Luffy, and fled Mary Geoise. I believe Dragon also got his scar from Garling, and that his burn mark is some kind of brand the Celestial Dragons use for those who try to take the title of god or dragon. Luffy contracted Sapphire Scales, and was going to die from it. So, Vegapunk cured Luffy, and then Dragon gave Luffy to Garp, and told him to make Luffy into a Marine so that Luffy could change the Marines from within. Since Luffy has the blood of a Celestial Dragon, Garp could protect Luffy from the WG if he became a Marine (Rosinante fits this too).
This is why Dragon said what he said about Luffy being a Pirate; he wanted Luffy to be a Marine, like Garp wanted.
Dragon loves Luffy as his son, even though he's Garling's biological child, like Kuma with Bonney. Shanks chose to raise Luffy, his father's bastard child, and protect him.
It's like Naruto if the Hidden Leaf Village wasn't full of assholes.
Anyway, Rob Lucci is Luffy's half brother. Like Luffy, his mother died giving birth to him. BUT Lucci was raised by the WG, and became... well, evil.
Garling raised Lucci, another bastard child, to be a murderous monster, and told him that he could only exist in this world through killing. BUT, Garp, who instructs WG soldiers in Rokushiki, taught Lucci, and helped him become kind. IMO Hattori was probably a gift Garp got Lucci to teach him how to love.
When Lucci is fighting Luffy, he tells Luffy that he wants to tell a certain idiot about Luffy, and that he's fit to be captain. That idiot is Garp, Lucci's teacher. Like Aokiji and Koby, Lucci has heard Garp bitch about his kid becoming a criminal for YEARS.
Jinbe knows Lucci through Garp (remember that Garp is friendly with Neptune, Shirahoshi, and Fish-Man Island), and knows Lucci isn't a bad guy. Jinbe and Lucci have probably talked before, as well.
Jinbe: "I'm surprised that someone as... ruthless as you views me as a person, Rob Lucci. I would have though you would view me as nothing but meat, to be frank."
Lucci: "I prefer human blood, to be frank. But, Garp told me I could trust you, and Garp taught me what justice is. You're a pirate, sure, but, you serve justice. You clearly wish for there to be peace; you are not my enemy, Jinbe, Knight of the Sea. I'm an assassin, who commits acts of evil in the name of dark justice, to maintain that same peace. Besides... it would be foolish, to act like you're lesser, just because you're an animal. I am a Zoan, after all. I identify as both man and beast. Hattori is the closest thing I've had to a friend, and he's a pigeon. So what if you're a fish. As long as you can understand my justice, I can understand you."
Jinbe knows what it's like to be a slave, to be an orphan. To Jinbe, Rob Lucci isn't a monster, but a tragic hero.
Jack, an orphan Fish-Man, was the person to help Kaido discover the Road Poneglyph. This means Jack also likely knows about Pluton.
Jinbe the Fish-Man will work with Lucci to stop Blackbeard from gaining Pluton, as Blackbeard will plan to use Pluton to attack Fish-Man Island to kidnap Shirahoshi, who Jinbe promised to protect in Otohime's stead.
I also am now officially shipping Vivi with Lucci, because this also makes Vivi Luffy's sister-in-law, since Lucci is Luffy's half brother.
Rob Lucci for Nakama.
You're awesome, Rambles. Keep Ramblin! WHOOOOOOOOOOOOOOOOOOOOOOO!
What a fucking world.
Forgot to mention this makes Shanks Luffy's half brother, which is really cool.
