You make it sound like Oda wouldn't pull that off
We all know, Oda is that kind of man!
How long has Carrot been with SHs???? Zou? WCI? Wano? Now, Onigashima???? What's her progress with Luffy? how close are they? Does Luffy even express how amazed he is with her? is Luffy clingy to her like other crew members???? Luffy gives ZERO FUCKS about her, so basically, why should I see value in her joining?
I personally do not believe that...
I personally think this arc will bring both Kaido/BM down...
then, We will have TWO big arcs:
1- One that will include Shanks/BB/Xebec
2- The last will include WG/Revolutionary army (Final War)
Rest of arcs will be like Zou, set up small arcs, that's what I believe
Yeah, he declared, but isn't necessarily going to take the throne just now! Just like how Momonosuke refused to take "Ame no Habakeri" sword saying not yet... end of this arc, he can easily say that he needs to become a man worthy of being shogun first, and his step towards that is reaching laugh tale and discovering what his father knew with Roger... it really is easy convincing argument to make to delay his shogunate
