I dont remember, are the SH aware than BM regained her consciousness? Or does Chopper still think she is the friendly O-Lin? If the latter i can expect some emoticon-worthy funny faces from him
Do you think there is any possibility to see Garp and Aokiji? Just thought about it out of the blue reading your comment, but that would match up better with the dog and pheasant....! Last time Drake reported to Sword, it was said that the Marine cant help coz too busy yea? That's perfect, Garp doesn't give a fuck about orders, he is the one who handled Rocks in the past, and Luffy is involved so i think it's enough reasons for him.... and I could see him being a part of Sword like Aokiji (even if no longer a marine, look at Drake)
As i wrote in a different post, I doubt Kaido would just reveal his secret entrance to BM just after they decided on a whim to ally... she is an enemy who could betray him at anytime, wouldn't make sense to casually reveal your hidden cards
