[Taka no Me]

Спойлер:

Main part is Illumi's talk with Hisoka.
Illumi expects Killua will ask Alluka to cure Gon but he'll not do it by himself. Killua will ask someone to do it and he'll try to grant 3 requests. Illumi estimates 10000or much more people(Killua's all family and even Hisoka) will die if Killua fail because Gon used enormous power.
Alluka has another character in himself(herself?). True Alluka is cute and calls Killua "oniichan(big brother)" but another one calls him "Killua".

Alluka's line.
"No!! I'm glad!! Ohhhhh, I smell you, big bro"
