Enjoyable chapter. I love that we finally got confirmation Caribou got his ride. The goof deserved it and happy to cross one more person off the list to wonder where they went after Wano. The crew discussion about Vivi was just the right type of feel I've missed. Luffy's dream moment felt a little forced but eh, it'll be a cute anime moment I'm sure. As far as which poneglyph is the most lost; I do like to believe some renegade minks that left home at some point would've either let out rumors either to their new loyalties or just accidentally on a bad drinking night. Meanwhile there's absolutely nothing to go off on the missing Fishman island poneglyph, since not even the Neptune or Jinbei had any knowledge about who could've snatched it.
I've seen some people have issue with why the government/Im would keep such a powerful weapon secret or what the downsides to this must be. Personally, I'm already good with what we see here and basic assumptions. Using such a powerful weapon publicly and regularly would drastically change the world order into something completely different and filled with fear and stagnation. Obviously if Im wasn't using it regularly, that means that type of world isn't what they want. They want the world as it already has been, thus this weapon is absolutely reserved for only the most drastic situations (to hide their own identity in this case) and in ways that can still keep it a secret (so the world can actually function outside of being terrified of this threat). But that's just my personal rationalization, will have to wait and see if Oda elaborates.
I don't think the writing of the situation works if one reads it as Lulusia was the target and Sabo was just coincidence. Narratively it needs to be that Sabo was the target and this attack can really be mobilized this fast. It helps give Im some cred a lot better than Blackbeard got for basically failing to raid Hancock.
I look forward to Bonney age changing shenanigans and I desperately hope Luffy and Chopper aren't about to be separated with Bonney for awhile.
