Gon was always a playful and supportive brother towards you, You both were inseperable, and will never let eachother down. ....though, there can be a huge difference between the both of you, He was more Energetic and Optimistic, however you were more of a Calm person and To be honest, you dont express emotions to anyone besides your brother Gon.

After finishing the hunters exam together with Gon and Killua, Gon remembered that Hisoka made an offer to him that cannot be denied..

"Dang it!! I completely forgot i had to punch Hisoka on the face to give his badge back!" he pouted, while killua insisted for him to train..

"Well, ...I do know a place where you can both train, and earn money at the same time..." Killua said. "The Heavens Arena!"
