After all the fights, beefs and chaos everything was over...everyone went there separate ways for a while until the gang all ran into each other, Killua, Gon, Leorio and Kurapika and they all decided that they would all become friends again. Of course Gon and Killua became best friends again and those pent up feelings of liking Gon came back all at once

Kurapika and Leorio obviously could tell Killua's feelings coming back like a train hit him. He was more gentle with Gon more caring and loving. Leorio has pointed it out multiple times just for Killua to shut it down like normal

Kurapika and Leorio put on the titanic cause Gon kept saying it was a good movie as Kurapika and Leorio kept complaining even though they were tearing up. Gon was bundled up in blankets watching with a blank face on while Killua walked over pissed off about a fight, even though he won he was still mad it happened as he plopped onto the couch

Kurapika: "Why are you so pissed off now?"

Killua: "A stupid kid said chocolate robots were gross and I got mad so we fought."

Leorio: "You're being dramatic, Killua-"

Killua: "SHUT UP OLD MAN!"
