Benn: Garp and Shanks’ influence indicates that Monkey or not, a crazy parental figure will have an effect. As will the sane one, as I have proved by imparting wisdom to Luffy like “remember to ask out the person you want to date” and “if you can’t punch it, ask yourself why to figure out what to do”
Shanks: Yeah. I mean, Luffy was already like me…but I think Ace and Sabo might have picked up a tendency or two…and somehow Ace got Garp’s narcolepsy. What’s up with that?
Garp: The weirdest part is that I’m fairly sure that hasn’t been genetic…Dragon doesn’t do it, Luffy almost never does it, but Ace does it….weird. And then there’s all the people who compare Luffy to Roger instead of Ace (and are weirdly correct in doing so…)
Rocinante: I’m more concerned about unleashing a kid with Luffy’s recklessness and Law’s plotting abilities on the world.
