Perospero is great, a candy arrow, never expected bow and arrow from, very versatile and talented in use of his DF.
Also we were shown a panel of moon when marco was about to be shot, I am assuming something with moon might happen probably getting hidden(or it was just to showcase that the two are in sulong form, since oda established sulongs are not game changer anyway).
But them attacking perospero is feeling the same as pedro attacking perospero, i.e. trying to get him offgaurd. Honestly as said earlier, I just hope he dumpsters everyone.
Also BM said she can't waste time with small fights, is she planning to fight Kaido? Since I am pretty sure marco is the strongest out of the alliance. And seems like marco is also not following her.
