Luffy is always curious, always eager for adventure.

He 's learned it a long time ago that when people don 't want to tell you things, you don 't ask. Ace punched him in the mouth too many times for him to not think twice now.

And eventually, he realizes that it 's fine.

Everyone carries a different weight. He doesn 't need to know all of them to have an amazing adventure with them, right?

Plus, he has the World 's Greatest Swordsman in his crew! That 's awesome.

Oh oh

oh

, but even cooler! Nami! She has a metal arm. How cool is that? Ace is gonna be SO jealous when he hears this. She has a

metal

arm--

'Luffy, you 're shaking the boat with your jittering. If you 've got too much energy, walk around the boat on your hands or something. '

And Luffy does exactly that.

Then he trips over Zoro, flips into the sea, and after being rescued by an angry Zoro, Nami punches him on the head.

Ow.
