That brother of killua deserves way more the title of being a 'killer' since his psychotic mind tricks are on a high level. It's not surprising that he can manipulate killua that easily.
Holy holy shit. You can just see all the manipulative tactics that Killua's brother was using on him. And Killua's poor little rant of wanting to be a normal kid with friends... i feel so bad for him...
While being disqualified, Killua also made Leorio pass. (Of course, as in the past, in the confrontation with Netero, he ruined his disability on someone else!) Hmm...
