Fantastic Chapter. I never was a huge Leorio fan, but him pleading for Gon's life was powerful stuff. He's really beating himself up over not being there for Gon in his time of need and, it will be interesting if the voters are swayed to go for him because of that. I still don't think he'll win, though. Pariston definitely has to have something up his sleeve.
Really like the stuff with Killua and Alluka as well. It seems he really will leave Gon, unless Alluka is going to travel with them from now. With her powers, though, it's just not practical. I think it's a great move from a storytelling standpoint, though, as it will cause Gon to have to suffer sever consequences for his actions against Pitou. Obviously he can't die, but losing his best friend is honestly just as bad. That's if that happens, though. I'm pretty much just speculating.
You know, with how much Killua and Leorio are doing for Gon it really makes it even stranger to me that Kurapika isn't around.
