Best moment to have yamato flashback was either:
1- When Luffy finally got rid of her shackles.
2- That moment when she met Kaido on the roof, before the Calamities fight started.
But now?
For real?
You do know that we STILL have filler fights, right?
Like that Ninja fight, Neko vs Perospero, Jack vs Inu and Killer vs Hawkins (and whatever Apoo and Drake might do).
Not only that, but we had almost Z-E-R-O updates on Law+Kidd vs Big Mom, aside from what was actually an update on Killer vs Hawkins.
There's still SO MUCH in this raid. And I believe that we will get a full 5-6 chapters backstory from Kaido still, when Momo+Luffy reach the roof.
It's like you're making a girl almost reach an orgasm, but you decide to stop what you're doing to change positions because you saw it in porn and you completely lose the momentum and she never reaches the orgasm that was already right there.
If you're going for the climax, you go for the climax.
