On Zou, Kinemon mentioned that Kaido killed Oden because he was attempting to pry information out of them. This could be a plothole. It definitely should have been mentioned in the Oden flashback. I need this plot line resolved in a satisfactory way, it makes no sense for Kinemon to know that Kaido is trying to pry information out of them since he didn't try to in the Oden flashback and straight after the execution, Kinemon & co travelled 20 years into the future and haven't seen Kaido since. Very weird.


Kaido wanting information from them is legit, but as you said, how does kinnemon know this?
He shouldnt be able to know it, so maybe he was just guessing or oda fucked this up.
