After Killua collapsed from his injuries from his fight against the Ortho Siblings, Ilkago brought him in the clinic to nurse him back to health for two days. After two days, Killua awakes and the doctor greedily demands him to pay large sum of money. Before payment, he demands the doctor to give him access to the phone with hefty service fee. After contacting Gon and being informed by the situation, he pays the fee to the doctor and leave the place.
