One day, stopping on an island, Luffy had captured someone, who he saw was a pirate and seemed to be very strong, fighting against some very strong navy guys and even having haki, obviously the others fought with Luffy for doing this, but as the person was there, they tied him to a chair while still unconscious **

There comes a time when Jinbei approaches to see what the person was like, upon seeing him he is immediately surprised, but happy

Jinbei: “Luffy, you can let him go, he is trustworthy”

the others don't understand, until he drops the bomb

others (Nami, Ussop, Chopper, Zoro, Sanji, Brook, Luffy and Franky): "WHAT?! ARE THEY YOUR HUSBAND/WIFE?"
