The only problem is that in the original anime, in order to flesh out the fight, they decided to deviate from the manga plot and place it ahead of Gon and Hanzo's fight (so that it wasn't simply an afterthought). In the manga, Gon is supposed to sleep through the fight, just as it happened in the newer version.
It seems they really are trying to follow the manga more closely in the newer version.
Except they're censoring the shit out of everything...
Yeah, the way they censor stuff has me quite confused. For instance, they have no problems showing Killua's face and hands smeared with blood after the fact, but they won't show any blood coming out when he is thrusting his hand into Bodoro's chest.
