See, this is all I really wanted people to understand. To preface, Carrot stans need to accept Yamato is joining. That is a FACT. But Yamato stans need to understand that there is "potential" for Carrot to pull the stowaway joke again.
I'm honestly in the Yamato camp, and i can unbiasedly see that this event with Carrot is weird. Take away her "irrelevance" in Wano, and you see still left with a character who witnessed an apparent traumatic event where said character left her his will, in which that same will was prefaced by this:
Then you can just combine that with the time this happened:
With not only Carrot but same gag happens to the kings:
So it's totally in line for her to do it yet again, especially to Inu and Neko lol. This chapter just leaves it off in a weird way. Wanda clearly is the "better" leader, older and had the same position as Carrot.
Again, I don't expect it to happen, but people need to get that if it does happen, it's a triple join with Jinbe, Carrot and Yamato, not a means to boot Yamato from the running. That is definitely not happening.
