Nothing really major, but a lot of small interesting stuff happened.
Garuu cutting articles about the Strawhats out of the newspaper, Zoro eavesdropping, the out of the blue party, Kinemon and Ganjuro finally arriving, Carrot's interesting reaction, Law trolling his crew etc.
Interesting turn of events though. If Luffy really is going to pick a fight with Big Mum while at the same time Kaidou is after him, this could inadvertently lead to Big Mum clashing with Kaidou. Despite the both of them being outrageous and completely mental, they still had the awareness till now to have some kind of a non-agression pact between all the Yonkou because they know very well that if one would start fighting the other, the world would be thrown into turmoil. On the other hand they are obliged to crush everyone who stands in their way, so either of them pretty much has to crush the Strawhats. It's a dilemma as backing down means losing face, but going through with it means a potential clash with another Yonkou. A situation like this likely never occurred to anyone as no one was ever bold, or stupid, enough to pick a fight with two Yonkou...simultaneously xd
