I enjoy the chapters Pretty much and completely disagree with you About being a mess. But thats just my opinion.
About Whitebeard and Oden... it is a difficult Task. I mean, Marco didnt asked for Oden so far we see, seems like he knew he is dead. Maybe they know About what happened to Oden and the time-jump, but no Details? So Whitebeard could have wanted to wait for the re-appearance of the scabbards to get Details?
I dont know, i hope to get a solution for the Situation. but how could BM make Whitebeard to step back if he wanted to go for Kaido?
