Any chances Yamato convinced Kaido to travel to Marineford and stop Ace's execution? Could Shanks be the real villain here?
Honestly, lemme take a leap here for a minute:
- Kaido loves his daughter enough to acknowledge her "male" appearance and inspiration. It seems like he does care about her enough to want his "son" at the party and has a group to go out and look for "him".
- Yamato knows Ace, seemingly friends with him. This is signficant.
- Kaido DOES respect Whitebeard. Hes jealous he died on his own terms, which Kaido can't do. Kaido also likely got along with Newgate when on the Rocks Pirates, all things considering.
- Yamato may or may not have heard of Ace's Execution. This prompts her to beg her father to help Whitebeard. Perhaps he accepts.
- Shanks stops Kaido for an unspecfied reason.
So yes, maybe we were tricked into believing Shanks wanted to stop Kaido to help WB, but instead he stopped Kaido to force WB's death.
I really think Shanks has been playing the long game.
