Nekomamushi said that he's gonna Kill Perospero
And let's be honest, Perospero implied he would have lost against Carrot & Wanda if they stayed Sulong
While Jack could Defeat entire Sulong Army, & he is comparable to Sulong Neko/Inu or slightly Weaker
So Neko vs Perospero doesn't make sense at all
Something must save Perospero & since next Chapter should be about Kid vs Big Mom
Then we might get Big Mom Pirates related Chapter (Which is basically also a Kid Chapter)
So what if Perospero actually pulls out Mont d'Or's Book & entire BM Pirates emerge !!
I really really wanna see that happening, so that the Raid becomes even more intense & Hype us for Conclusion in next Volume
This is very possible cuz Oda chose to let Perospero fight outside the Castle in an Open Space
So it makes sense for him to release his Siblings there
With Neko, Denjiro, Kawamatsu & Izo free to Fight again & also Killer/Drake could Defeat Hawkins/Apoo while still in good shape, not to mention the SHs who are also Free now (For example Brook & Chopper didn't have a Fight & they both went to WCI & lost against BMP, so it's better they get their Payback against them rather than fight Beasts Pirates)
If the Chapter is truly filled like this, it can actually be End of Act 3 & many actually Theorized about this, cuz the numbers add up
