This chapter actually has a bit of opening for discussion.
I wonder if Pufu's going to fight Gon. To be honest it could go either way, but I really hope it ends up with Gon vs. Pitou. Pufu seemed sort of pissed off at the end, although I think he's more intent on finding the king then fighting Gon. Also, seems like Killua was going back to Gon. Maybe Killua will confront Pufu in the next chapter for a little bit of a skirmish. All in all, it really seems like the protagonists are screwed.
The Yupi fight I think could be resolved with the protagonists winning, but I think they might need a bit of Novu's help.
The Pufu fight, I'm completely and utterly lost when it comes to this one. It seems like Pufu vs. Morau is completely out of question considering Morau doesn't have his pipe and he NEEDS to help Knuckle, or else Knuckle's just going to get his ass whipped. Gon probably won't fight Pufu, but there is a chance for Killua I suppose. Shoot is obviously out of question. Now, I really think Novu should do something like retrieve Morau's pipe. Otherwise, it seems like there really isn't anyone who is in the position to defeat Pufu. Maybe Pufu will interrupt Netero vs. the King and the King will get pissed and injure/kill Pufu? Although I would prefer a real fight, if he was injured, it could put one of the protagonists in a better position to oppose him.
As for the Pitou fight, I'm pretty sure Gon vs. Pitou is set in stone. If someone else fought Pitou, it just wouldn't be as impacting and enjoyable. Not to mention Gon doesn't look like he really wants to get a fight with someone else other than Pitou.
As for Palm, it looks like she's going to be turned into a Chimera Ant. This might be a reason for Novu's return (so he can save her).
