He wants to meet Luffy again after he is more mature, manly and stronger to "get back his hat"
Pretty gay if you think about it
- He set sails, lives in sea, spending time for weeks or months in sea, with all crew men.
- He loves to drink, but contrary to Doffy / Blackbeard / Kaido etc who partying with bitches, he drinks only with his guys.
- When he is upset, his moodbuster is seeing a boy's wanted poster.
- When he moves, all the conversation he wants to talk are about men (Ace to Whitebeard, certain man to Gorosei).
- He is crippled thus can't clean his own ass, so he lets his men cleans it for him when he doesn't wear any shorts every morning. He lets his guy sees his d*ck all day everyday.
- Even from his children, all the characters he is pretty close with are all guys, from Buggy to Mihawk to Beckmann to child Luffy erc.
- Luffy also doesn't like women and he is inspired by his childhood hero.
There are more and more clues around when you think about it..
