She already said it was a gamble, but she knows the stuff about the 20 years into the future, how Momo and company should reappear, then 20 years happen, and foreigners arrive into Wano opposing Orochi and Kaido, including Zoro who was good enough to save her and Toki, so it makes sense she would connect the dots.
-More Yamato vs Kaido
-Possible hints to why Yamato got bewitched by Oden and why Kaido is the way he is
-Luffy and Momo crashing through the mansion was funny as hell
-Cool combo attack against Kaido
-Beggining of what will probably be the final fight
I dunno whats there not to like
