When Gon introduces Retz to Killua
"Retz meets Gon, and the two soon become friends. Gon asks Retz for help in locating the place where the person who stole Kurapika's eyes might be hiding at. When Gon introduces her to Killua; Killua is instantly jealous of the quick bond Gon and her had already formed."
Lol proof that Killua got jealous.
I got that from Retz description XD
