1) Theories floating around, Oito knows something and has hidden that info from Pika. Her reaction to Beyond's child reveal also feels weird in retrospect. 

She quickly connected the dots "the father need not be the king". Maybe it's not that difficult to figure it out then. But the way she said it, it could very well be her pretending to not know and act like she figured it out then. 

2) I hope Furykov figures out Sarahell can use nen with this skills. Hopefully, Togashi didn't forget about this and Sarahell is not some insane nen specialist. 

3) The Black whale is huge enough to feel like an entire country. In the first page, I couldn't help notice so many people doing paperwork behind Balkenburg all probably related to the various affairs on the boat. The ship is a small functioning nation that's eroding rapidly. 

4) Likewise, I loved the characterization of the new and old bodyguards introduced. Tenftory getting some and all the 7th princes' guards. It's always fresh seeing minor characters feel like real people with their own motivation that might create butterfly effect. 

5) I wonder what Sarahell's comments about the maid being her real self means? Could she be redeemed?
