I honestly cant figure out what Gon and Killua are missing according to Biske´s words. In case of Gon it could have been typical stuff like "the will to kill" or whatever, but Killua certainly wouldn´t be missing that. So, I´m left without an idea.
Netero killing those lowly squadrons and being all content with himself feels wrong. Even Gon and Killua, prior to their training, maybe could have beaten the squadron leaders. Cant wait for the clash between Netero and the Royal Guard.
Oh, and I absolutely want to see Pitou put in place. Dat pussy is to arrogant for my liking :>
