One of the things I'm curious about with Loki going forward is his perspective on Xebec and how it might relate to Luffy/BB. He clearly admired him, but why? Was Xebec's morality more similar to Luffy or to Blackbeard when Loki first meets him? Does Xebec espouse personal liberty and that inspires Loki? Or does Xebec talk about burning the world down and making himself king, and that appeals to Loki's young angst?
It might be that Xebec, much like Blackbeard, is pretty similar to Luffy in a lot of ways short of morality, and that Loki saw the same thing in Xebec that most characters see in Luffy or Blackbeard after a short exchange with them and that's why he idolized him. Which then brings up the question is if tsundere ol' Loki would prefer Luffy's "everyone's free to do what they want, and we all get along under no king" or Blackbeard's "everyone's free to do what they want to become king, feelings be damned"?
