Ok maybe this isn't the trial by fire that Luffy will be going through to master his Busoshoku Haki. At least both Luffy and Hyogoro survived and Luffy has taken a step forward.
The bad news is that Big Mom regains her memories. Of course it was going to happen sooner or later. However, by some stroke of luck, Big Mom falls asleep and the Beasts Pirates bind her in Seastone chains. I hope Big Mom reaches Kaido's island so I can watch Kaido and Big Mom destroy each other, but Big Mom will have to break free first.
Anyway, with Queen and Big Mom both out of the Prisoner Mines, now is Luffy and his allies' chance to start the prison uprising.
