He watched as Zoro glanced over at the others. "Well, captain, I guess I wouldn't be thrilled if you decided you wanted us to sail under another man's flag." "Would you leave?" Luffy was gripped with a sudden terrible panic that Zoro's soft look and little shake of his head immediately assuaged. "Never." Two years ago, in the first few months when they had met, Luffy was sure that the answer would have been 'yes'. He let go of Zoro's hand and twined his arms around his arm in a curling spiral instead, walking as close to him as possible. They were quiet together for a moment, bathed in the last warm rays of twilight and the soft chatter of the rest of the Straw Hats, and the former Heart Pirates and Doflamingo– all of them surrounded by the greater, distant noise of the crowd and Uta's song. When Luffy had been little, talking with Ace and Sabo about how they'd all be pirate captains, he didn't really understand what that meant, or why it meant that the three of them couldn't sail together. It had been Zoro who taught Luffy what being a captain meant. He still wasn't sure that he understood it. Or maybe it was more that there was a part of him that didn't quite like the answer. Pride. Pride and rank. It made him think of the marines.  And he hated it.

Niji smiled, that soft, real smile again, slightly pained, and took her wrist in his hand.He turned it over and looked over her veins. "The surgery I was dreaming about. It was when Caesar put the ports into my arms for injections." Rebecca's eyes trailed down his arm—to the very ports he was talking about. The ports installed to make it easier for them to receive their injections through that hard internal—carapace? She still wasn't sure what it was called.  The little silver ring there gleamed like a piercing in the middle of his arm.
