You replaced Uvogin

You were taken by Kurapika, you being Chrollo's favorite, he did all he could to get you back but nothing was to avail, so he decided to meet up with Kurapika

Chrollo: "I want her back! Now! " Kurapika: "I want Gon and Killua back! "

Chrollo let's go of Killua and Gon, but Kurapika doesn't let you go

Chrollo: "Now, give her back to me. "
