By the way on topic of Carrot again, I wanted to point out something that maybe could give some people that want Carrot for Nakama or just want a proper send off to Carrot, a bit of hope for it.
Aside from what I pointed out in my previous message about how Carrot could still join, as Neko and Inu did with Whitebeard by staying 3 days undiscovered, there's actually another thing to keep in mind when having an arc finished in One Piece. Luffy and the crew always give a send of to important or relevany characters to them or just in the story. For some reason in Wano, the Minks and Carrot didn't get one. Therefore there must be something with them, to not get one.
Yo may point out characters like the Scrabbards or Hiyori not getting one, but I just don't feel as they are that connected to the Strawhats as the Minks were, at least that's what I think.
Here's someone who pointed out, each and every send off there have been in One Piece since it began, so that you see how odd it is that Oda hasn't given them an actual send off, specially to Carrot (if she isn't in the Sunny that is).
The chances are slim, but not impossible.
Note: It's in Spanish, so you'll have to constantly translate it.
