Super serious stuff, of course.
-Asked Nami, Sanji, Usopp and Brook's last names
-There are normal-sized humans and giants, but why are there a whole mess of people in the inbetween range (Moria, Admirals, Doflamingo, etc.)? Similarly, is there any explanation for characters with random horns (Moria again, Hannyabal, and now Caesar).
-Is one 1 berry supposed to be approximately equivalent to 1 yen, and if so, are we supposed to interpret it given the current, modern value of the yen?
-I asked about the changing character designs over the years- like if that's just Oda's natural, subconscious process, or if he had any explicit reasons for any specific changes, such as with Chopper, who is barely recognizable as the character he once was.
-Before Akainu (and his inspiration, Sugawara Bunta) were revealed, I asked if he would be based on Minegishi Toru (at Alina's behest), based on this clip where Toru + Aokiji and Kizaru's inspriations all appear together, wearing their admiral colors. (skip to 00:35:
