The Zs are monitoring Killua.
Killua wished that if he does not leave the mountain (the Zs live inside one, remember) in the next 30 minutes with Alluka then his mother will die, otherwise Alluka will kiss him on the check.
Alluka accepts the wish.
Bunch of guys minus Kurapika and Leorio visits Gon (still in a coma).
Killua's mother was remarking about how much Killua has grown prior to making the wish.
the visitors list:
Its spoken of Biscuit, Hanzo, wing, knuckle and Tetzugera.
Pretty much most guys Gon has met along the way are visting him.
Killua's using the wish as a mechanism to get out. He wished to leave with Alluka within 30 minutes, otherwise his mother dies. He obviously is aware that he is being watched.
Alluka makes 3 trivial demands from Killua.
Miluki remarks that he didn't know it was so cheap to wish for a PC. This angers Silva, and Miluki says he'll never do it again.
In the past, Silva asked Killua why he doesn't wish from Alluka, and Killua replied that's not how you treat a friend. After that Killua got needle in his head for *correction* from Ilumi.
Killua wishes to leave the mountain with Alluka in 30 minutes or his mother dies.
Killua revealed that if you make a wish for Alluka to do something constructive, Alluka must physically touch the object. Destructive powers have no range limitations.
Morel calls Killua and said he found an aura remover, but Killua says that's no good, leave it to him.
The head butler calls Killua saying the Zs were evasdropping the call and says from the call the Zs are afraid other people might figure out Alluka's ability. This placed Killua on level 4 surveilance.
Level 4 criterias:
Certain topics are forbidden.
Other family members/butlers will be following him.
If he violated the rules they will catch him home.
Survilience level will be increased to 5.
Level 5 criteria:
Can't leave the confined area at all.
Killua got a level 4 warning for being defiant to his parents and taking Alluka with him.
He got assigned the following criterias:
Can't talk to outsiders without permission.
Cannot leave more than 1 meter from Alluka.
Can't let anyone know Alluka's power.
Silva assigned the two most powerful butlers who are said to be unimaginably powerful blah blah blah.
Alluka suddenly makes demand from one of the butlers for her finger nail. The butler obliged and said now Alluka can't demand from others, and then said she will be nearby, and then disappeared.
Killua realized it was a trap, but says even without the ability to wish, he still can command and will save Gon.
