Kurapika was with Gon, Killua and Leolio, fighting against Omokage and the puppets he created at the image of the Phantom Troupe members, until you suddenly arrive with the rest of the Phantom Troupe, and your comrades start fighting off their copy while you go and fight your copy that was about to attack Kurapika. Upon seeing you, Kurapika freezes, his eyes going wide. He started seeing colors. And he knew what that meant. You're his soulmate.
