@RobZilla:
You didn't care about exposition concerning a mysterious character like Jack and the crew of a Yonko in general?
It's either Yonko or GTFO. Nobody cares about underlings anymore, so it has to be someone of substance. Unless we see him on equal standings with an Admiral, he's a no one. The fact that he didn't take on Tsuru, Sengoku, and Fujitora by himself means he's fodder.
Or the flashback as a whole, finally giving us some explanation as to what exactly happened when Jack ravaged Zou?
Flashbacks are for noobs, only the present matters. The fact that Jack is no longer there means it doesn't matter. We should focus on what that sexy red head is doing, because we haven't seen him since the War.
Or the introduction of new and important characters for this arc?
Said character will just be like Dressrosa. We get introduced and they won't have any important role:ninja:
Or the link back to Punk Hazard and Caesar's auctioning off of his crazy weapons?
Being serious for a second, I have to wonder how Jack got his hand on the weapon. Ceasar showed it off but he got captured before being able to sell it and show how it works.
Back to shenanigans. Punk Hazard was a terrible arc, so we should never have reference to such a terrible arc again. therefore this is a terrible development.
I'm genuinely mystified.
That's because it was all according to plan, because it was Dio all along.
disclaimer: I'm being snarky because I want to and this isn't directed towards anyone in particular.
