Oh and Wano is about to really reach its climax now, Big Mom hinted Wano may guard some secret about the One Piece.
Opening it's borders seems like a really big deal.
Momo delaying it along with Kaido and Big Mom being thrown out of the picture will probably lead to something against the World Government, whose CP0 agent conviniently just left Onigashima.
I would expect some big lore dump reveals as well as the real conclusion to Kaido (and no he won't awaken or do some shit again).
The ending feels off because it really is off, Momonosuke delayed the opening of the borders for a reason.
